zloy xaker [14]

Answer:

24 g of C are needed to produce 1mol of CH₄

Explanation:

The reaction is:

2C (s) +  2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g

What is the correct way to write 0.0000250 m in scientific notation?
yulyashka [42]
Scientific notation is: n * 10^a, where n is a number between 1 and 10 ( but not 10 itself ) and a is an integer.

Answer:
0.0000250 m = 2.5 * 10^(-5) m.

Which of the following would increase the pressure acting on a closed-system chemical reaction?
Nitella [24]

Answer:

Increase the temperature of the chemical reaction.

Explanation:

the reason you would increase the temperature to increase pressure is that heat usually makes reactions occur faster but also expands the gasses and solids itself. the expansion of gasses and solids creates more pressure in a closed-system.
