It shouldn't have any lone pairs since it is a tetrahedral structure. Ge has 4 valence electrons. Each H has 1 valence electron. Therefore, each H valence electron will pair with each valence electron on Ge.
¿What? For you bye, i love you, no sabo ingles.
Answer:
The reaction is not at equilibrium and reaction must run in forward direction.
Explanation:
At the given interval, concentration of NO = 
Concentration of
= 
Concentration of NOBr = 
Reaction quotient,
, for this reaction =
species inside third bracket represents concentrations at the given interval.
So, 
So, the reaction is not at equilibrium.
As
therefore reaction must run in forward direction to increase
and make it equal to
.
Answer:
D. chlorine, oxygen, nitrogen, hydrogen.
Explanation:
- Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>ν ∝ 1/√M</em>
where ν is the rate of effusion and M is the atomic or molecular mass of the gas particles.
- The molecular mass for the listed gases are:
O₂: 32.0 g/mol,
Cl₂: 70.906 g/mol,
N₂: 28.0 g/mol,
H₂: 2.0 g/mol.
- Hence, the smallest molecular mass of the gas, the fastest rate of effusion.
So, the order from the slowest to the fastest rate of effusion is:
<em>Chlorine, oxygen, nitrogen, hydrogen.</em>
