Describe the process of evaporation.

1 answer:

5 0

Hopefully this helps, this is basically simplified but you could ask me for a more detailed explanation. But evaporation works by water on the ground(puddles, lakes, etc) turn into a vapor, which means the water tunrs into gas, which is invisible. Then that water goes up and is stored in the clouds which would then become water and fall into a puddle and the cycle repeats! Hope this Helped!

The chemical equation for the formation of ammonia is unbalanced. 3H2(g) + N2(g) -----> NH3(g) If three molecules of hydrogen

mestny [16]

Answer: 2 molecules of ammonia

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the formation of ammonia is:

$3H_2(g)+N_2(g)\rightarrow 2NH_3$

According to stoichiometry,

3 molecules of hydrogen combines with 1 molecule of nitrogen to give 2 molecules of ammonia.

How many molecules are in 3 moles of potassium bromide (KBr)

sattari [20]

Answer:

Your strategy here will be to use the molar mass of potassium bromide,

KBr

, as a conversion factor to help you find the mass of three moles of this compound.

So, a compound's molar mass essentially tells you the mass of one mole of said compound. Now, let's assume that you only have a periodic table to work with here.

Potassium bromide is an ionic compound that is made up of potassium cations,

, and bromide anions,

−

. Essentially, one formula unit of potassium bromide contains a potassium atom and a bromine atom.

Use the periodic table to find the molar masses of these two elements. You will find

For K:

39.0963 g mol

−

For Br:

79.904 g mol

−

To get the molar mass of one formula unit of potassium bromide, add the molar masses of the two elements

M KBr

39.0963 g mol

−

79.904 g mol

−

≈

119 g mol

−

So, if one mole of potassium bromide has a mas of

119 g

m it follows that three moles will have a mass of

moles KBr

⋅

molar mass of KBr

You should round this off to one sig fig, since that is how many sig figs you have for the number of moles of potassium bromide, but I'll leave it rounded to two sig figs
