Answer:
the answer is 5⁷
Explanation:
it is 5 to the power of 7 because 5 is it base and then the 4 and 5 get added to get ur exponent
"The vapor pressure will decrease and the boiling temperature will increase." When sodium chloride is added to water, the vapor pressure above the resulting salt solution is less than the vapor pressure above the pure water, and the boiling point of the salt solution will be greater than the boiling point of pure water. This results from the introduction of salt molecules to water, in which the salt solution needs a higher temperature for the vapor pressure to be equal to the pressure of the atmosphere.
Answer: B.) Salt and water
Explanation: A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
Hope this helps :)
Answer:
Melting = endothermic, solid = exothermic
Explanation:
Ok so when ice cream melts, that requires heat, so it’s Endothermic. In order to melt it, it requires heat, heat is entering. When it becomes solid again, that is exothermic because it is losing heat in order to become cool again.
Answer:
1/t means that the order of reaction is a first order. Meaning that the rate of reaction is directly proportional to reactant concentration. Scientists work with the standard units, therefore 1/t is 1 divide by 1 second.
