Answer:
A table salt molecule is bigger than a salt molecule.
Explanation:
I'm saying this because it's a table salt and salt could be much smaller and table salt could be bigger.
<u>Answer:</u> The concentration of diluted bleach solution is 0.0157 M
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:

where,
are the molarity and volume of the concentrated bleach solution
are the molarity and volume of diluted bleach solution
We are given:

Putting values in above equation, we get:

Hence, the concentration of diluted bleach solution is 0.0157 M
Well you see its part sodium and sodium is another word for salt so It is a salt because it is formed by the reaction of an acid and a base
Answer:
The answer is
<h2>6.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
density = 2.7 g/mL
mass of aluminum = 16.2 g
The volume is

We have the final answer as
<h3>6.0 mL</h3>
Hope this helps you
We subtract the enthalpies of the reactants from that of the products:

Since this is < 0, this is an exothermic reaction.
