Answer : In the reaction of Ca +
--->Ca
, the coefficient of Ca and
will be the same which will be 1.
Explanation : As per the rules of writing a chemical equation and balancing it properly, the number of elements in reactants side should be equal to the number of elements generated in product side. Hence when we use 1 molecule of Ca and one molecule of
then it generates 1 molecule of Ca
.
Answer:
Milk boils at about 212 F (100 c)
Explanation:
A physical property is a property in which a chemical change is not nessecary to undergo to know about.
Since all the other options require a chemical change to know, they are not physical properties.
The third option is a physical property because it does not require a chemical change to know.
Answer:
1) The value of Kc : (C.) remains the same
2) The value of Qc : (A.) is greater than Kc
3) The reaction must : (B.) run in the reverse direction to reestablish equilibrium.
4) The number of moles of Br2 will : (B.) decrease
Explanation:
Value of concentration equilibrium constant Kc depends only on temperature. Since temperature remains constant, therefore, Kc remains constant. Decrease in volume means increase in pressure. Increase in pressure favors the side with less gaseous species. Hence, increase in pressure will favor the reverse reaction towards reactants.
I think it would be 125 per mile
