Answer: let me figure it out rlly quick
Explanation:
They use natural resources like sunlight water they need soil water and sunlight to grow the stem should be pliable and firm and will have a green cast on the inside
Answer:
It means these compounds are only made up of two elements.
Explanation:
Binary compounds:
The compounds which are made up of the atoms of only two elements are called binary compounds.
For example:
The following compounds are binary:
HCl
H₂O
NH₃
HCl is binary because it is composed of only hydrogen and chlorine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.
water is also binary because it is also made up of only two elements hydrogen and oxygen.
While all polyatomic compounds are not binary. for example,
H₂SO₄
It is made up of hydrogen, sulfur and oxygen. There are three elements are present in this compound. So, it is not binary compound.
Answer:
Only Reaction 1
Explanation:
In reaction 1, there is a change in state from solid to liquid. Hence, there is an increase in number of ways particles and their energies could be arranged. As a result, entropy increases.
In reaction 2, there is a decrease in amount of gas particles (4 mol to 2 mol). Hence there is a decrease in the number of ways particles and their energies could be arranged. As a result entropy decreases
