Answer:
hot air rises and expanded the balloon
Explanation:
thats it.
The answer is B.mass because like the periodic table it determines the elements by mass
Quick look: In its modern sense, epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. It can apply to characteristics passed from a cell to its daughter cells in cell division and to traits of a whole organism
Are there any answer choices? If not, here are some possible responses you may see (that are correct, of course):
*It is used in the process of decomposition.
*It is used to release ammonia from dead animals that ultimately gets turned into nitrogen-based substances.
*It involves the formation of nitrates into nitrogen to complete the nitrogen cycle.

Considering the equation,
3Na₂SO₄(aq)+2Al(NO₃)₃(aq)------>Al₂(SO₄)₃(s)+6NaNO₃(aq)
As it can be seen from the equation,
2 moles of Al(NO₃)₃ reacts with 3 moles of Na₂SO₄ to give 1 mol of Al₂(SO₄)₃.
Here 690 mL of 2.5 M Al(NO₃)₃=2.5× 690/1000
=1.7 mol of Al(NO₃)₃
As 2 moles of Al(NO₃)₃ give 1 mol of Al₂(SO₄)₃
So 1.7 mol of Al(NO₃)₃ give 1.7/2 mol of Al₂(SO₄)₃
so it will give 0.86 mol of Al₂(SO₄)₃.
Moles=mass given /molar mass
molar mass of Al₂(SO₄)₃= 342.1509 g/mol
Moles= mass given/342.1509
0.86=mass given/342.1509
mass of Al₂(SO₄)₃=295.1 g
so 295.1 g of Al₂(SO₄)₃ will be produced.
