Answer:
less dense
Explanation:
the reason that the density would be lower is because the air bubbles keep the maximum amount of atoms possible from being in that space. imagine pouring a glass of soda from a freshly opened bottle, at first it looks like there's a lot in the glass but as the bubbles dissipate, there's less and flat soda appears to have even less in the glass. i hope this analogy helped :)

M is molarity here not metre
Answer:
0.0008 mole of HCl
Explanation:
From the balanced equation between HCl and NaOH:
1 mole of acid requires 1 mole of base for neutralization.
mole = molarity x volume
mole of NaOH = 0.02 x 0.04 = 0.0008 mole
mole HCl = 0.16 x 0.01 = 0.0016 mole
Since 1 mole of NaOH requires 1 mole of HCl for neutralization, it means that 0.0008 mole of NaOH will require 0.0008 mole of HCl. The remaining mole of HCl must have been neutralized by the antiacid:
0.0016 - 0.0008 = 0.0008 mole.
Therefore, 0.0008 mole of HCl must have been neutralized by the antiacid.
Answer:
<h2>
2 is the coefficient of CO₂</h2>
Explanation:
The <u>coefficient</u> is the number in front of a substance that indicates how many molecules or atoms are. For example, when we see 5He, it shows that there are 5 atoms of helium. When we see 5H₂O, it indicates that there are 5 molecules of water, each having 2 atoms of hydrogen and 1 atom of oxygen, so a total of 10 hydrogen atoms and 5 oxygen atoms.
Answer : The correct option is, (2) Fission reaction.
Explanation :
- Fission reaction : This is a type of nuclear reaction in which the splitting of bigger nuclei into two smaller nuclei takes place. During this process, the large amount of energy is released.
- Redox reaction : This is an oxidation-reduction reaction in which the electrons transferred between the two molecules.
- Substitution reaction : In this reaction, one functional group is replaced by the another functional group in a chemical compound.
- Neutralization reaction : In this reaction, the acid and base react to give water and a salt.
Redox reaction, substitution reaction and neutralization reaction are the chemical reactions in which the heat releases when the chemical bonds are breaking and forming.
Therefore, the greatest amount of energy released per gram of reactants occurs during the fission reaction.
