Ocean currents determine the various directions of wind movement.

<h3>What is ocean current?</h3>

Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.

Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

How many grams are there in 9.40 x 10^25 molecules of H2? with prove so i could understand how you got it. if you can thank you
Nadya [2.5K]
Convert amount of molecules into moles using Avogadro’s number

9.40 x 10^25 molecules H2 x 1 mole / 6.02 x 10^23 molecules

= 156 moles H2

Convert moles of H2 into grams using H2’s molar mass (1.01 x 2 = 2.02)

156 mol H2 x 2.02 g / 1 mol
= 315 g H2

The heat of vaporization for water is 40. 7 kJ/mol. How much heat energy must 150. 0 g of water absorb to boil away completely?
netineya [11]

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.

The heat required for the vaporization has been given as:

Q=m\Delta H_{vap}

<h3 /><h3>Computation for the Heat of vaporization</h3>

The heat of vaporization of water has been given as, \Delta H_{vap}=40.7\;\rm kJ/mol

The mass of water sample has been, m=150\;\rm g

Substituting the values for the heat energy absorbed, <em>Q:</em>

<em />

<em />Q=150\;\times\;40.7\;\rm kJ\\&#10;\textit Q=6,105\;kJ

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

Consider the balanced equation below. 4nh3 3o2 right arrow. 2n2 6h2o what is the mole ratio of nh3 to n2? 2:4 4:2 4:4 7:2
KIM [24]

The required mole ratio of  NH₃ to N₂ in the given chemical reaction is 2:4.

<h3>What is the stoichiometry?</h3>

Stoichiometry of the reaction gives idea about the number of entities present on the reaction before and after the reaction.

Given chemical reaction is:

4NH₃ + 3O₂ → 2N₂ + 6H₂O

From the stoichiometry of the reaction it is clear that:

4 moles of NH₃ = produces 2 moles of N₂

Mole ratio NH₃ to N₂ is 2:4.

Hence required mole ratio is 2:4.

What is the mass of 6.02 x 10^23 atoms of arsenic?
Anvisha [2.4K]

Answer:

Mass = 74.9 g

Explanation:

Given data:

Number of atoms of arsenic = 6.02×10²³ atoms

Mass of arsenic = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022× 10²³ is called Avogadro number.

one mole =  6.02×10²³ atoms

So number of moles of arsenic are 1 mol.

Mass of arsenic:

Mass = number of moles × molar mass

Mass = 1 mol ×  74.9 g/mol

Mass = 74.9 g
