Worms are fully developed insects and larvae are not.
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water.
If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up.
That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

Answer:
The answer is 30 g of sodium hydrocarbonate
Explanation:
This is a acid-base reaction, so in order to neutralise the spilled acid, the mol of spilled acid should be calculated.
M = n / V => n = M x V = 0.028 x 6.2 = 0.1736 mol
Since 1 mol of sulfuric acid generates 2 mol of H⁺, so the mole of H⁺ is 0.3472 mol or 0.35 mol with two significant figures.
To neutralized the acid, we need at least the same mole of base, so we need at least 0.35 mol of NaHCO₃, which can be converted to its mass at 29.4 g.
Since the answer need to be expressed in two significant figures and also need to make sure to neutralize all the acid, so we will use a little excess base. The answer is 30 g.
Answer:
The net ionic equation:
Explanation:
The given chemical reaction is as follows.
The total ionic equation is as follows.
Similar ions on the both sides of the reaction will be cancelled.
The remaining reaction is
Therefore, the net ionic reaction is as follows.
Gas 2 because it has more particles that are colliding
