Answer:
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle.
solve using the chemical equation and molar mass
Explanation:
Answer:
A) Nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds.
Explanation:
Methane is formed when nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds. Nonmetals share electrons to form covalent bonds.
Good luck! :)
Given:
Sulfur dioxide and dihydrogen sulfide system
Vapor Pressure of water, H2O = 23 torr
P_SO2 = P_H2S
Temperature of the system = 298 K
Assume: Total pressure of the system is 1 atm = 760 torr
If partial pressure of SO2 is equal to the concentration of H2S, then,
760 = 0.5*PSO2 + 0.5PH2S
760 = PSO2
Hey there!
There are 6.022 x 10²³ particles in 1 mole.
We have 3.55 moles.
6.022 x 10²³ x 3.55
2.14 x 10²⁴
This is how many particles we have.
NaCl has 2 atoms for every unit.
So we multiply this by 2.
2 x 2.14 x 10²⁴ = 4.28 x 10²⁴
There are 4.28 x 10²⁴ atoms in 3.55 moles of sodium chloride.
Hope this helps!
