Which climate condition is typically found in the tropics due to the interaction of the atmosphere and hydrosphere?
A.Dry with low humidity
B.Dry with high humidity
C.Wet with high humidity
D.Stormy with low humidity
Answer:
A- Dry with low humidity
Explanation:
The hydrosphere includes the water which is on the surface of the earth, below the ground and in the air.
On analyzing the climatic conditions in the tropics due to the interaction of the atmosphere and hydrosphere, the presence of water droplets in tropics is less resulting in less humidity and, thus the climatic condition is dry.
Therefore the climatic condition that is typically found in tropics due to interaction of the atmosphere and hydrosphere is dry with low humidity.

A mixture contains 220 mmHg of CO, 350 mmHg of Ne and 840 mmHg of He. What is the total pressure of the mixture
a
1.86 at
b
1.59 atm
c
1.46 atm
d
none of these
Considering the Dalton's partial pressure, the correct answer is option a.: the total pressure of the mixture is 1.86 atm.
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
[tex]P_{T} =P_{1} +P_{2} +...+P_{n}[/tex]
where n is the amount of gases present in the sample.
This relationship is due to the assumption that there are no attractive forces between the gases.
In this case, a mixture contains 220 mmHg of CO, 350 mmHg of Ne and 840 mmHg of He. The total pressure of the mixture can be calculated as:
[tex]P_{T} =P_{CO} +P_{Ne} +P_{He}[/tex]
[tex]P_{T} =220 mmHg +350 mmHg+840 mmHg[/tex]
Solving:
[tex]P_{T}[/tex]= 1410 mmHg
Being 760 mmHg=1 atm, then:
[tex]P_{T}=1410 mmHgx\frac{1 atm}{760 mmHg}[/tex]
Solving:
[tex]P_{T}[/tex]= 1.86 atm
Finally, the correct answer is option a.: the total pressure of the mixture is 1.86 atm.

Answer:
These weather conditions are consistent with droughts, often characterized by hot, dry, weather. When this is the case, it is important to conserve water and use it only for necessities. Garden sprinklers are not essential, so their use can be sacrificed in order to provide more crucial services, such as drinking water. This rule has been put in place in order to avoid water shortages and energy crises, events that would be even more damaging during an emergency.
why is extra vitamin C excreted in urine from the body but vitamin A in excess is retained in the body
Answer:
Vitamin C is water-soluble and not stored in your body
In contrast to fat-soluble vitamins, water-soluble vitamins do not get stored within the body. Instead, the vitamin C that you consume gets transported to your tissues via body fluids, and any extra gets excreted in urine ( 1 ).
Answer:
The reason vitamin C isn't stored well is because your body can't make it, and vitamin C is a water-soluble vitamin. This means it dissolves in water, and what your body doesn't use right away is excreted through urine. Thus, it is not stored in our body to a significant extent.

Anser is C Agl
Explanation:
Agl does not dissolve in water.
All of the following compounds are soluble in water except AgI because of very high value of lattice energy. Therefore, the correct option is option C.
The capacity of a material, the solute, to combine with a different material, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration for the solute within a saturated solution—a solution where no more of the substance can be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. The two compounds are considered to be at the point of solubility equilibrium at this time. All of the following compounds are soluble in water except AgI because of very high value of lattice energy.
Therefore, the correct option is option C.

In the chemical stockroom, there is a 0.500 L bottle filled with 2.30 M CuSO4 solution. How many moles of CuSO4 are in the bottle?
A. 0.217 moles
B. 4.60 moles
C. 01.15 moles
D. 1.80 moles
The number of moles of the solute in the solution is the product of its volume and molarity. The number of moles of copper sulphate in 0.500 L of 2.30 M solution is 1.15 moles.
What is molarity?Molarity of a solution is the common term used to represent the concentration of a solution. It is the ratio of its number of moles of solute to the volume of solution in liters.
Molarity = no.of moles/volume in L.
Molarity is a temperature dependant quantity.
The given solution has a volume of 0.500 L.
molarity of copper sulphate solution = 2.30 M
Thus, number of moles of copper sulphate solute dissolved in 0.50 L of water is calculated by multiplying the volume with molarity.
No. of. moles of copper sulphate = molarity × volume
= 0.500 L × 2.30 M = 1.15 moles.
Therefore, there will be 1.15 moles of copper sulphate in the solution.

Darren looks up at night and sees a bright object with a tail moving quickly across the sky. What is the most likely object that Darren saw? A. an asteroid B. a meteor C. a comet . D. a cupid
Answer:
A
Explanation:
asteroids most often leave trails due to the large amount of friction that occurs.
The bright spatial object with a tail moving fastly across the sky is called a comet. Comets are made of rock, dust and ices.
What are comets?Comets are orbiting snowballs around sun made of frozen gases, rock, and dust. They enlarge to the size of a sizable town when frozen. A comet heats up and ejects dust and gases into a huge, blazing head that is larger than most planets when its orbit puts it near to the Sun.
Millions of kilometers away from the sun, the dust and gas combine to form a tail. The Kuiper Belt and much further Oort cloud are presumably home to billions of comets that orbit our sun.
Some of their ice begins to melt and boil off as the comet approaches the sun, along with some dust. The coma, which is created by these particles and gases, surrounds the nucleus.

Select True or False: Consider the reaction N2(g) 3H2(g) 2NH3(g). The production of ammonia is an exothermic reaction. When heat is added to the equilibrium system it will shift to increase the amount of ammonia produced.
Answer:
False
Explanation:
As I like to think of it, equilibrium will shift either 'forwards' (to increase products) or 'backwards' (to increase reactants) to oppose any change in system;
If heat is added, the equilibrium will shift in the direction that reduces heat within the system;
In other words, it will shift in favour of the endothermic reaction, i.e. the reaction where heat is gained by the molecules/atoms and therefore taken out from the system;
If the 'forwards' reaction, producing NH₃, is exothermic (i.e. energy is released in the reaction), then the 'backwards' reaction is endothermic;
So the equilibrium will shift in this direction, which is the reaction of 2 NH₃ molecules producing N₂ and 3 H₂

A student wants to determine the melting point of water as part of an investigation into the strength of electrostatic forces. The student considers determining the freezing point of water instead. Is this a valid option?
According to the forces of attraction freezing point and boiling point of water are different and are not related to strength of electrostatic forces.
What are forces of attraction?
Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

D) 39.6
E) 7.01 x 10-6
Answer:
Answer: 0.66 hours
Explanation:
[tex]{ \rm{time = \frac{distance}{speed} }} \\ \\ { \rm{time = \frac{(950.5 \times 1000) \: m}{400 \: m {s}^{ - 1} } }} \\ \\ { \rm{time = {2376.25 \: s}}}[/tex]
• Remember 1 second accounts for 1/3600 hours
[tex]{ \rm{time = \frac{2376.25}{3600} }} \\ \\ { \rm{time = 0.66 \: hours}}[/tex]
The time taken by object traveling at a speed of 400 m/s to reach 950.5 km distance is 0.66 hr or 39.6 min.
What is average velocity ?
Average velocity is given by the total distance covered by the object in total given time. SI unit of velocity is m/s.
Here in this question it is given that the object is travelling with speed v of 400 m/s and it is to find the time t to reach 950.5 km distance d.
it is known that 1 km = 1000 m
that is 950.5 km = 950500 m
Now, using the relation of speed-distance to find time t to reach 950.5 km distance :
[tex]\begin{aligned}v&=\frac{d}{t}\\t&=\frac{d}{v}\\&=\frac{950500}{400}\\&=2376.25 \text{ s}\end{aligned}[/tex]
Now converting 2376.25 sec into hrs by dividing it by 3600 we get :
2376.25/3600 = 0.66 hr or 39.6 min.
Therefore, the time taken by object to reach 950.5 km distance is 0.66 hr or 39.6 min.
