Answer: d. Remove one-half of the initial CaCO3.
Explanation: Le Chatelier's principle states that changes on the temperature, pressure, concentration and volume of a system will affect the reaction in an observable way. So in the reaction above:
A decrease in temperature will shift the equilibrium to the left because the reaction is exothermic, which means heat is released during the reaction. In other words, when you decrease temperature of a system, the equilibrium is towards the exothermic reaction;
A change in volume or pressure, will result in a production of more or less moles of gas. A increase in volume or in the partial pressure of CO2, the side which produces more moles of gas will be favored. In the equilibrium above, the shift will be to the left.
A change in concentration will tip the equilibrium towards the change: in this system, removing the product will shift the equilibrium towards the production of more CaCO3 to return to the equilibrium.
So, the correct answer is D. Remove one-half of the initial CaCO3.
Yes cellulose is alive because it contains cells
Answer:
10 km/hr
Explanation:
We are told that a jogger runs;
3km in 0.3 hr and
7 km in 0.7 hr
We are required to determine the average speed;
We need to know that average speed is given by;
Average speed = Total distance ÷ total time
In this case;
Total distance = 10 km ( 3km + 7 km)
Total time = 0.3 hr + 0.7 hr
= 1 hr
Thus;
Average speed = 10 km ÷ 1 hr
= 10 km/hr
Therefore, the average speed of the jogger is 10 km/hr
