Answer : The value of reaction quotient Q is, 0.498
Explanation:
Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given balanced chemical reaction is,

The expression for reaction quotient will be :
![Q=\frac{[CO][H_2]}{[H_2O]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BCO%5D%5BH_2%5D%7D%7B%5BH_2O%5D%7D)
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now we have to calculate the concentration of 

and,

and,

Now put all the given values in the above expression, we get:

Thus, the value of reaction quotient Q is, 0.498
Answer: Electrons
Explanation:
Most of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons have the least mass of an atom's particles.
<h3>
Answer: 4.25 g/ml %</h3>
Explanation:
weight/volume percentage concentration = (mass in g ÷ volume) × 100
= (0.850 g ÷ 20 ml) × 100
= 4.25 g/ml %
∴ the weight/volume percentage concentration of the sucrose solution is 4.25 g/ml %.
Answer:
Moving Across a Period
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons
