The equation looks like this:
KBr + AgNO3 —-> KNO3 + AgBr
The products are potassium nitrate and silver bromide
Vol.250 before its to much pressure
To
determine the empirical formula of the compound given, we need to
determine the ratio of the elements present in the compound. To do that we use the given amount of sample
of the compound and the masses of each of the element included. Then, we calculate for the number
of moles of each element. We do as follows:<span>
mass moles
Potassium 5.81 0.1486
Chlorine 5.27 0.1487
Oxygen 18.21 - 5.81 - 5.27 = 7.13 0.4456
Dividing the number of moles of each element with
the smallest value of number of moles, we will have the ratio of the elements:</span>
K = 1 Cl = 1 O = 3
Therefore, the empirical formula would be KClO3.

90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you
Explanation:
Answer is: A. adding heat to the product mixture.
Balanced chemical reaction:
CO(g) + 3H₂(g) ⇄ CH₄(g) + H₂O(g); ΔH = -206.1 kJ.
This reaction is exothermic, which means that heat is released.
According to Le Chatelier's principle when the reaction is exothermic heat is included as a product and when the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the left.
