Answer:
Mass of products equals mass of the reactants. If you build a campfire like this one, you start with a big pile of logs. As the fire burns, the pile of logs slowly shrinks. By the end of the evening, all that's left is a small pile of ashes.

Add 2 that’s why and I said if
Answer:
1.758 x 10⁻¹¹.
Explanation:
∵ pH = - log[H⁺].
∴ 5.47 = -log[H⁺].
log[H⁺] = -5.47.
∴ [H⁺] = 3.388 x 10⁻⁶ M.
∵ [H⁺] = √(Ka.C)
∴ [H⁺]² = Ka.C
<em>∴ Ka = [H⁺]²/C </em>= (3.388 x 10⁻⁶)²(0.653) = <em>1.758 x 10⁻¹¹.</em>
Answer:
Explanation:
Here, we want to get the new volume of the gas
What we need to know is the law that connects volume and pressure at constant temperature
The law that supports this is the Boyle's law
It states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature
Mathematically, we can have this as represented as:

We can proceed mathematically to solve as follows;
answer D
