Explanation:
The net equation will be as follows.
So, we are required to find 
for this reaction.
Therefore, steps involved for the above process are as follows.
Step 1: Convert K from solid state to gaseous state
, 
= 89 kJ
Step 2: Ionization of gaseous K
, 
= 418 KJ
Step 3: Dissociation of 
gas into chlorine atom
.
, 
= 122 KJ
Step 4: Iozination of chlorine atom.
, 
= -349 KJ
Step 5: Add 
ion and 
ion formed above to get KCl
.
, 
= -717 KJ
Now, using Born-Haber cycle, value of enthalpy of the formation is calculated as follows.
= 89 + 418 + 122 - 349 - 717
= - 437 KJ/mol
Thus, we can conclude that the heat of formation of KCl is - 437 KJ/mol.
I am pretty sure it is the most reactive elements
The correct answers :
It increases with a decrease in the concentration of H₂(g).
It decreases with an increase in the concentration of S₂(g).
It decreases with an increase in the concentration of H₂(g).

Forward reaction : rate to form product
In equilibrium :
The product decreases ⇒ system will move from left to right(forward reaction)
The product increases ⇒ system will move from right to left(reverse reaction)
Explanation:
Rate = 84mL/s
A minute has 60 seconds;
Rate = 84mL/s * 60s = 5040 mL/minute
Volume of blood in a minute = Rate * Number of beeats per minute
Volume = 5040 * 72 = 362880 mL
How long to circulate 3500ml?
1 minute = 362880mL
x = 3500 mL
x = 3500mL min / 362880mL
Math Expression:
Time to circulate 3500ml of blood (min) = 3500ml * 1 minute / Volume of blood at a rate of 84ml/s and 72 beats per minute (ml)
