Answer: Fluorine
Explanation: It belongs in the same group as Bromine
Answer:
According to Le Chatelier's principle, increasing the reaction temperature of an exothermic reaction causes a shift to the left and decreasing the reaction temperature causes a shift to the right.
Explanation:
C6H12O6(s) + 6O2(g) ⇌6CO2(g) + 6H2O(g)
We are told that the forward reaction is exothermic, meaning heat is removed from the reacting substance to the surroundings.
According to Le Chatelier's principle,
1. for an exothermic reaction, on increasing the temperature, there is a shift in equilibrium to the left and formation of the product is favoured.
2. if the temperature of the system is decreased, the equilibrium shifts to right and the formation of the reactants is favoured.
3. if the reaction temperature is kept constant, the system is at equilibrium and there is no shift to the right nor to the left.

Explanation:
<u>Answer:</u> The moles of hydrochloric acid is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

Or,

We are given:
Molarity of solution = 0.5173 M
Volume of solution = 
Putting values in above equation, we get:

Hence, the moles of hydrochloric acid is
