Explanation: these both have chemical and physical changes happening to them.
Answer:
H2 is Molecular hydrogen. It is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond
Explanation:
Answer:
Elements that have atomic numbers from 20 to 83 are heavy elements, therefore the ratio is different. The ratio is 1.5:1, the reason for this difference is because of the repulsive force between protons: the stronger the repulsion force, the more neutrons are needed to stabilize the nuclei.
The Answer would be e: 3.2 g/L
<span>At STP : p = 1 atm and T = 273.15 K
molar mass Cl2 = 70.906 g/mol
d = molar mass x p/RT = 70.906 x 1 atm / 0.08206 x 273.15=3.16 g/L</span>

What is the empirical formula?
Answer:
Hi, There!
- ,the empirical formula of a chemical is a simple expression of the relative number of each type of atom (called a chemical element)
- Empirical formula is defined as the formula of a compound which gives the simple whole number ratio of the atoms of various elements present in one molecule of compound.
Hope this Helps!
