What would be the effect on this reaction of increasing the temperature?
2H2 + O2 = 2H20 + energy
A) the rate of formation of H2O would increase
B) The forward reaction would be favored
C) Increasing the temperature would not have an effect on this reaction
D) The rate of the forward reaction would decrease
Answer:
D) The rate of the forward reaction would decrease
Explanation:
The statement that describes effect on the reaction of increasing the temperature is "the rate of the forward reaction would decrease."
What is temperature?Temperature is the measurement of a body's level of hotness or coolness.
The average kinetic energy of the system is measured by temperature. The kinetic energy of particles in a matter raises as they move faster, which boosts the temperature of the system. When two bodies of differing temperatures come into touch, heat is the energy exchanged between them.
The term "exothermic reaction" refers to a reaction that releases energy. An exothermic reaction, in other words, produces heat. The temperature of the reaction will rise unless it is cooled in some way. When you use an external heater to raise the temperature, it slows or reverses the reaction, reducing the number of products while increasing the amount of reactants.
Hence the correct answer is D.

However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

Why are different detergents made for cleaning different surfaces and how their chemical structure/composition affects this?
Answer: This is because of the different chemical composition of the types of detergents affects their cleansing actions.
Explanation:
Detergent means any substance which has the ability to clean an object. This includes soaps, soap powers and dish washing liquids as well as water. Detergents fall into two main types
--> Soapy detergents and
--> Soapless detergents
Soapy detergents are sodium salts of fatty acids. They are saponification products of fats and oils. In the chemical composition, each molecule of soap possesses a long hydrocarbon chain attached to an ionic head. The hydrocarbon tail is hydrophobic, so it is insoluble in water but soluble in oil and organic solvents. The ionic head is hydrophilic, so it is soluble in water. Due to this dual nature, when is dissolved in water, the soap molecule forms spherical clusters called MICELLES( hydrocarbon tails points inward and ionic heads point outward). Repulsion between the similarly charged ionic heads keeps the micelles apart. This property helps the soapy detergent to lift grease from grease coated fabrics when applied to it.
While the chemical properties of the Soapless detergents has a hydrophobic tail and a hydrophilic head. The hydrophobic tail is either a long chain hydrocarbon or a benzene ring with a long alkyl group attached. The hydrophilic head, unlike the Soapy detergents, can be positively or negatively charged or even neutral. These chemical properties makes it to have a more favourable and wider application than soapy detergent.it is suitable for washing acid - sensitive fabrics and for breaking up oil slicks.
Calculate the molarity of each aqueous solution with the given amount of Nacl58.44 and final volume. A .3.30 in 0.340L,6.00mol in 550ml,0.0160mol in 9.00ml
Answer:
For A: The molarity is the solution 9.706 M
For B: The molarity of the solution is 10.91 M.
For C: The molarity of the solution is 1.78 M.
Explanation:
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.
The formula used to calculate molarity:
[tex]\text{Molarity of solution}=\frac{\text{Number of moles of solute}}{\text{Volume of solution (L)}}[/tex] ......(1)
For A:
Number of moles = 3.30 moles
Volume of solution = 0.340 L
Plugging values in equation 1:
[tex]\text{Molarity of solution}=\frac{3.30 mol}{0.340 L}=9.706 mol/L[/tex]
For B:
Number of moles = 6.00 moles
Volume of solution = 550 mL = 0.550 L (Conversion factor: 1 L = 1000 mL)
Plugging values in equation 1:
[tex]\text{Molarity of solution}=\frac{6.00 mol}{0.550 L}=10.91 mol/L[/tex]
For C:
Number of moles = 0.0160 moles
Volume of solution = 9.00 mL = 0.009 L
Plugging values in equation 1:
[tex]\text{Molarity of solution}=\frac{0.0160 mol}{0.009 L}=1.78 mol/L[/tex]

22 Determine the molar mass of an unknown gas that has a volume of 72.5 mL at a temperature of 68C, and a pressure of 0.980 atm and a mass of 0.207 g.
Answer:
81.5g/mol
Explanation:
Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.
To solve this question we must find the moles of the gas in order to obtain the molar mass using:
PV = nRT
PV / RT = n
Where P is pressure = 0.980atm
V is volume in Liters = 0.0725L
R is gas constant = 0.082atmL/molK
T is absolute temperature = 68°C + 273.15 = 341.15K
0.980atm*0.0725L / 0.082atmL/molK*341.15K = n
2.54x10⁻³ moles = n
Thus, the molar mass of the gas is:
0.207g / 2.54x10⁻³ moles
81.5g/molconvert 2.41 x 10^2 m to cm
answer choices
2.41cm
2.41 x 10^4cm
2.41 x 10^-2cm
2.41 x 10^-6cm
Answer:
2.41*10² m equals 2.41*10⁴ cm
Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{c*b}{a}[/tex]
In this case the rule of three can be applied as follows: if 1 m equals 100 cm, 2.41*10² m equals how many cm?
[tex]cm=\frac{2.41*10^{2} m*100 cm}{1 m}[/tex]
cm= 24100 = 2.41*10⁴
2.41*10² m equals 2.41*10⁴ cm

A solution of 12M HCl is diluted so that it goes from 550mL to a total volume of 1000mL. What is the new concentration of the solution?
Answer:
6.6M
Explanation:
C=concentration
V=Volume
C1V1=C2V2
rearrange formula to find C2
(C1V1)/V2= C2
(12M x 550mL)/1000mL= C2
6600M*mL*/1000*mL* =C2 (cancel units)
6.6M=C2

Suppose you have 1000 lb of waste copper (II) oxide sitting in the basement of your factory. Do you see a problem with sending it to a landfill?
Answer:
Yes.
Explanation:
Yes, we have a problem with sending it to a landfill of copper oxide because it has harmful effect on the health of humans as well as more weight of the copper oxide. Copper oxide usually found in powder form which can easily be inhaled that causes death of the cell due to toxic effect on the mitochondria and lysosomes of the cell. It makes problem of health in carrying the copper oxide from the basement of the factory to the landfill region due to its power form so we can say that it can do problems to human health while carrying from one place to another.
