Answer:
Expand
Explanation:
When you heat up a substance it expands
Answer:
6.76*10^-4 , or 6.8*10^-4 if you consider sig figs
Explanation:
This is a bit of a confusing question, since it incorrectly states that the acid disassociation constant is simply [H+][F-].
Ka = [H+][F-]/[HF] , so plugging in the values, we get
If we were to use the equation in the question, Ka=[H+][F-], we would get the answer 6.76 * 10^-6 , which is not the Ka for HF
<span>The equation of the reaction for the production of the phosphorus trichloride is : 2P + 3CI2 = 2PCI3. Carlos added 15g of phosphorus, but there are two molecules of phosphorus in the chemical reaction, this implies that, there are 7.5g of phosphorus for each phosphorus atom, therefore, we are going to multiply both sides of the chemical reaction by 7.5. 2 * 7.5 = 15. Then 15 * 3 = 45. Thus, 45g of chlorine will be found in the product.</span>
Answer:
Endothermic reactions is the result of heat being absorbed.
Explanation:
Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.
(These are all examples of endothermic reactions.)
