Answer:
Neither of them have more particles than the other.
Explanation:
Neither of them have more particles than the other because;
1 mole of any substance usually contains 6.022 × 10^(23) atoms/molecules/particles of that very same substance.
Thus, it will be the same value for Gold (Au) and water(H2O).
Explanation:
The Sun's gravatitional pull drags the earth around the earth as well with the other planets surrounding the sun

1. Remember (sum of products) - (sum of reactants)
So ΔHrxn = 2 ΔHf [H2(g)] + ΔHf [Ca(OH)2(s)] - 2 ΔHf [H2O(l)] - ΔHf [Ca(s)]
= 2*0 + -986.09 kJ/mol - 2*(-285.8 kJ/mol) - 0
Do the math and you'll have the answer. BTW the ΔHf [H2(g)] and ΔHf
[Ca(s)] were 0 because these are elements in their standard states.

Answer:
<h3>The answer is 3.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 15 g
volume = 5 mL
We have
We have the final answer as
<h3>3.0 g/mL</h3>
