Which phenomena does wind cause?
A)tides and waves
B)deep currents and tides
C)waves and surface currents
D)surface currents and deep currents
HELP PLEASE ILL GIVE OUT BRAINLIEST
The phenomena which wind causes are waves and surface currents.
What are surface currents?
Surface currents are caused by winds which blow over the ocean water and result in creation of waves. Surface currents are horizontal streams of water which are capable of flowing thousands of kilometers and can reach great depths.
Surface currents play a major role in determining the climate all over the world. They are influenced by three major factors 1) overall global wind patterns 2)rotation of earth 3)shape of ocean basins . When a surface current collides with the land it changes the direction of currents.
Because of surface currents the global climate has warmer water from equator to the cooler parts of the ocean as they transfer heat energy.

If 9 moles of P203 are formed, how many
moles of O2 reacted?
NEED HELP ASAP WILL GIVE BRAINLIEST
Answer:
First we know that the molar mass of CO2 is 44.01g/mol, and that the sample of CO2 contains 3.408 x 10^21 molecules, and we have to find the mass of that sample.
We know that moles = mass/molar mass, if we rearrange the equation for mass, we'll get:
mass = moles x molar mass
Also, note that the number of atoms/molecules in a sample is the moles of the sample x Avogadro's number (6.02 x 10^23)
If we rearrange the equation for moles, we would get:
moles = molecules of sample/6.02 x 10^23
Plug in the values for the equation above to get the moles:
moles = (3.408 x 10^21)/(6.02 x 10^23)
moles = 0.00566112956 (we're not done yet)
Now that we have the moles and we were already provided the molar mass, we can calculate the mass using the very first equation we rearranged.
mass = moles x molar mass
mass = 0.00566112956 x 44.01
mass = 0.2491g (answered 4 places past the decimal point)
Therefore the sample of Carbon Dioxide has a mass of 0.2491g

If the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture in a buret
Answer:
f the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture
Partial pressure of H2 in gas mixture is :
739.765 torr .
Explain total pressure?The overall pressure ptot is the total of all pressures in a reference system. This pressure, according to Bernoulli (see Fluid mechanics), consists of the static pressure p, the dynamic pressure pdyn, and the geodetic component ( g z) that exists in a fluid along a stream line in a frictionless flow.The total pressure of a gas mixture is the sum of its component gases' partial pressures: Ptot = ∑Pi = P1 + P2 + P3... ntot = total number of moles in the gas mixture (the sum of all ni).Total pressure of mixture =
Partial of hydrogen + Partial pressure of oxygen
Partial of Hydrogen = Total pressure - partial pressure of oxygen
Here total pressure = 757.3 torr
Partial pressure of oxygen = 17 . 535 torr
Total pressure = 757 . 3 - 17 . 533
= 739.765 torr.

Octane has a density of 0.703 g/ml. Calculate the mass of CO2(g) produced by burning one
gallon of octane. There are 3.79 liters to one gallon.
The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.
The given parameters:
Density of the octane, ρ = 0.703 g/mlVolume of octane, v = 3.79 litersThe mass of the octane burnt is calculated as follows;
[tex]m = \rho V\\\\m = 0.703 \ \frac{g}{ml} \times 3.79 \ L \ \frac{1000 \ ml}{L} \\\\m = 2,664.37 \ g[/tex]
The combustion reaction of octane is given as;
[tex]2C_8H_{18} + \ 25O_2 \ --> \ 16CO_2 \ + \ 18H_2O[/tex]
From the reaction above:
228.46 g of octane -------------------> 704 g of CO₂ gas
2,664.37 of octane --------------------> ? of CO₂ gas
[tex]= \frac{2,664.37 \times 704}{228.46} \\\\= 8,210.3 \ g\\\\= 8.21 \ kg[/tex]
Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).
Answer:
Molecules don’t have to collide with each other in order to experience intermolecular forces.
Molecules with permanent dipoles, held in fixed orientation, such as water molecules in the solid state (ice), interact with a potential proportional to the inverse cube of distance. This intermolecular force always exists, no matter how far apart the molecules are; every water molecule interacts with every other water molecule. However, because it diminishes rapidly with distance, it tends to only be important at short distances. (In contrast, the potential between two ions goes as 1/r, and that between an ion and a dipole goes as 1/r^2.)
The van der Waals forces, of which London dispersion forces are the most important, are described by a potential proportional to the inverse sixth power of distance. Theoretically, those forces are always operating between any two atoms or molecules, but again, only become important at short distances.

Answer:
n = 0.324 mol
Explanation:
PV = nRT
STP:
273.15K and 101.325kPa
n = PV/RT
n = (101.325kPa)(7.27L)/(8.314 L kPa/mol K)(273.15K)
n = 0.3243693408 mol
