How many liters of oxygen gas, at standard temperature and pressure, will react with 35.4 grams of calcium metal? Show all of th
Margaret [11]
Answer: 19.8 l


Explanation:

1) Chemical equation:

2Ca + O₂ → 2CaO


2) Mole ratios: 2 mol Ca : 1 mol O₂ : 2 mol CaO

3) Convert 35.4 g of Ca to moles:

n = mass in grams / molar mass = 35.4 g / 40.1 g/mol = 0.883 mol

4) Volume proportion: 1 mol of gas at STP = 22.4 l


1 mol at STP              0.883 mol at STP

--------------------- = ------------------------------

22.4 l                                      x

⇒ x = 0.883 mol × 22.4 l / 1 mol = 19.8 l ← answer

Why are ionic compounds solids
enot [183]

Answer: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points.

In this chemical reaction, how many grams of h2 will react completely with6.50 moles of CO
geniusboy [140]

52 g of hydrogen H₂

Explanation:

I will assume that the problem is talking about the hydrogenation of carbon dioxide CO₂ not carbon monoxide CO. It is harder to reduce carbon dioxide than carbon monoxide and if you manage to reduce carbon dioxide you can reduce the carbon monoxide as well.

This reaction it will take place in the presence of catalyst at a specific temperature and pressure.

CO₂ + 4 H₂ → CH₄ + 2 H₂O

Now taking into the account the chemical reaction we devise the following reasoning:

if         1 mole of CO₂ react with 4 moles of H₂

then   6.5 moles of CO₂ react with X moles of H₂

X = (6.5 × 4) / 1 = 26 moles of H₂

number of moles = mass / molecular wight

mass = number of moles × molecular wight

mass of H₂ = 26 × 2 = 52 g
