I’m thinking
It conducts electricity when Molten.
Answer:
Volume of liquid = 28.7 mL
Explanation:
Given data;
Density of solid = 3.57 g/ml
Mass of solid = 19.5 g
Volume of water = 23.2 mL
Total volume when solid is dropped into graduated cylinder= ?
Solution:
Density = mass/ volume
v = m/d
v = 19.5 g/ 3.57 g/ml
v = 5.5 mL
Volume of liquid = volume of water + volume of solid
Volume of liquid = 23.2 mL + 5.5 mL
Volume of liquid = 28.7 mL
I don’t see any equal signs to make it an equation. Am I missing something?
Answer:
The forward reaction is occurring at a faster rate than the reverse reaction.
Explanation:
Reaction quotient (Q) of the given reaction is -
![Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%7D)
where [NO],
and
represents concentrations of respective species at a certain time.
Here
= 0.80 M,
= 0.050 M and [NO] = 0.10 M
So, 
Hence 
It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of
and
which makes Q higher than K.
Answer:
B
Explanation:
Option B is the correct answer. When you add 7 in front of the O2 in the left side, and then you add 4 and 6 in front of NO2 and H2O respectively, the number of oxygen atoms is the same in both sides.
