<em>Atoms</em> comprise of the nucleus and electrons.
A <em>molecule</em> <u>comprises of two or more,</u> <em>identical</em> or <em>different</em> <u>atoms</u>, combined chemically.
Answer:
All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Atoms come together to form molecules, which are the building blocks for all types of matter
Answer : 13.64 mL
Explanation : The reaction requires 13.64 mL of NaOH
From the reaction we know that oxalic acid requires two moles of NaOH so we have to calculate the number of moles of both.
0.150 L X 0.1500 moles/L = 2.25 X 
So the moles of NaOH will be 2 X (2.25 X ) = 4.5 X
Now, we know the concentration of NaOH as 0.330 M
4.5 X moles / 0.330 moles/L = 0.01364 L or 13.64 mL
So, the volume of NaOH needed to neutralize oxalic acid will be 13.64 mL
Answer:2 is the correct answer
Explanation:
Enthalpy of vaporization is the amount of energy that must be added to a liquid substance to transform that substance into gas.
The chemical reaction is expressed as:
<span>Cl2(g)+H2O(l) -> HOCl(aq) + H+(aq) + Cl- (aq)
</span>Reduction reaction is a reaction that loses electrons while reacting.The half reaction which represents the reduction reaction is written as:
<span>C<span>l2</span>+2<span>e<span>−1</span></span>→2C<span>l<span>−1
