Answer:
16
Explanation:
FIRST AND FOREMOST, BALANCE YOUR EQUATION.
Al + S8 ➡️ Al2S3
Numbers of Al=1. ➡️ Numbers of Al = 2
Numbers of S =8. ➡️ Numbers of S. = 3
USE COEFFICIENT TO BALANCE THE EQUATION.
16Al + 3S8 ➡️ 8Al2S3
Now the Numbers of Al and S in both sides of eqn. is balanced
The Answer Is 16
Answer:
It reacts explosively with oxygen.
Explanation:
Reactivity is a chemical property.
Taste, temperature, and density are all chemical properties.
Answer:
1.23 moles
Explanation:
Ideal gas law
PV = n RT R = .082057 L-atm/mol-K
25 C = 298.15 K
12 (2.5) = n (.082057) (298.15) n = 1.23 moles
Answer:
The atomic number equals number of protons and electrons
This is true when an atom is in neutral state.
Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is the name of the liquid state of H2O at standard conditions for temperature and pressure.
