I believe that would be a parasitism because one organism benefits yet the other is harmed.
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:
If we use a thick foil, then more α particles would bounce back, and no idea about the location of positive mass in the atom would be available with such certainty.
Answer: Synthesis
Explanation:
2 or more substances combine to form a new compound. In this case 2Na(s) combined with Cl2(g) to make 2NaCl(s)
