Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).
Explanation:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
2H₂O(g) → 2H₂O(l)
- To add the two equations: we omit H₂O(g) that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation
- So, the overall chemical equation is obtained by combining these intermediate equations is:
<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>

Answer:
1.32 mole
Explanation:
The following data were obtained from the question:
Volume of solution = 2.2L
Molarity of solution = 0.60M
Mole of Li3PO4 =..?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is represented as:
Molarity = mole /Volume
With the above formula we can easily calculate the number of mole of Li3PO4 as shown below:
Molarity =mole /Volume
0.6 = mole of Li3PO4 /2.2
Cross multiply
Mole of Li3PO4 = 0.6 x 2.2
Mole of Li3PO4 = 1.32 mole
Therefore, 1.32 mole of Li3PO4 is contained in the solution.
Answer:
4/15
Explanation:
15/15 - 11/15 = 4/15
If 11/15 is the probability that it'll rain tomorrow, then the rest should be the probability that it'll not rain tomorrow.
