Pls help I don’t understand: Which of these is a balanced chemical reaction?

Chemistry
1 answer:
nata0808 [166]2 years ago
3 0

Answer:

C) 2CO + O₂ →   2CO₂

Explanation:

The equation C is correct.

2CO + O₂ →   2CO₂

This equation have four oxygen atom and two carbon atoms on both side of equation. So it is correctly balanced.

All others are incorrect:

A) CO + O₂ →   CO₂

this is incorrect because there are three oxygen atoms on left while two atoms on right.

B) CO + 2O₂ →   2CO₂

this is incorrect because there are five oxygen atoms on left while four atoms on right.

D)  2CO + 2O₂ →   2CO₂

this is incorrect because there are six oxygen atoms on left while four atoms on right.

Answer:

663 g

Explanation:

Step 1: Write the balanced equation

2 LiOH + CO₂ ⇒ H₂O + Li₂CO₃

Step 2: Calculate the moles corresponding to 825 L of CO₂

At standard pressure and temperature, 1 mole of CO₂ has a volume of 22.4 L.

825 L × 1 mol/22.4 L = 36.8 mol

Step 3: Calculate the moles of H₂O formed from 36.8 moles of CO₂

The molar ratio of CO₂ to H₂O is 1:1. The moles of H₂O formed are 1/1 × 36.8 mol = 36.8 mol.

Step 4: Calculate the mass corresponding to 36.8 moles of H₂O

The molar mass of H₂O is 18.02 g/mol.

36.8 mol × 18.02 g/mol = 663 g

<h3>What is hydrogen made of?</h3>

Hydrogen can be produced from various domestic resources such as fossil fuels, biomass, and the electrolysis of water by electricity. The environmental sustainability and energy efficiency of hydrogen depends on how hydrogen is produced.

Hydrogen is the simplest element. Each hydrogen atom has only one proton. Hydrogen is also the most abundant element in the universe. Stars like the Sun are mainly made of hydrogen. The sun is essentially a giant sphere of hydrogen and helium gas.

Some facts about hydrogen:

  • Hydrogen is the most abundant element on earth.
  • Hydrogen is an alternative fuel with a very high energy content by weight.
  • The fuel cell can be used to power multiple applications.

  • Fuel cells are a clean way to generate electricity.

Fuel cell vehicles are very similar to traditional gasoline vehicles
