Answer:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Explanation:

The thermochemical equation for the combustion of methane can be obtained as follow:

Methane (CH₄) under goes combustion in the presence of air (O₂) to produce carbon dioxide (CO₂) and water (H₂O). This can be represented in the equation below:

CH₄ + O₂ —> CO₂ + H₂O

Thus, we can balance the equation as follow:

CH₄ + O₂ —> CO₂ + H₂O

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H₂O as shown below:

CH₄ + O₂ —> CO₂ + 2H₂O

There are a total of 4 atoms of O on the right side and 1 atom on the left side. It can be balance by putting 2 in front of O₂ as shown below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Now the equation is balanced.

If 35.8 grams of LiCl are dissolved in 184 grams of water, what is the concentration of the solution in percent by mass?
uysha [10]
Mass of solute = 35 grams
Mass of solution = mass of nacl + mass of water = 35.8 + 184 = 219.8 grams


Concentration = mass of Nacl x 100/mass of solution.

= 35x100/219.8 = 15.92%.

Hope this helps you.

The molecular weight of NaCl is 58.44 grams/mole. If you had a 1.0 molar solution (1.0 M), you would have to put 58.44 g of salt
Andre45 [30]

Answer:

5,844 grams of NaCl

Explanation:

Knowing the molecular weight 58,44 g/mole and saying 1 molar solution is 58,44 of NaCl in 1 liter of solution. 100 mL means 10% of the whole solution then we are going to have 10% of NaCl

58,44 x 0,1 = 5,844 grams of NaCl
