Answer:
number of moles= 0.844 moles
Explanation:
Number of moles of Hydrogen atom = given mass / molar mass
given mass= 0.850 g
Molar mass= 1.007 g
number of moles= 0.850/1.007 = 0.844 moles
Answer:
X and Z
Explanation:
If the difference in electronegativity between two atoms is greater than 1.7, they will form an ionic bond.
W and Z: 3.2 - 1.5 = 1.7 no
X and Z: 3.2 - 0.93 = 2.27 yes
Y and Z: 3.2 - 2.0 = 1.2 no
W and Y: 2.0 - 1.5 = 0.5 no
X and Y: 2.0 - 0.93 = 1.07 no
W and X: 1.5 - 0.93 = 0.57 no
X and Z are most likely to form an ionic bond together.
Hope this helps.
It should be 3.36 g / min but i m not sure
A - its condensation and gas particles have a higher kinetic energy
