Answer:
the energy of the products is less than the energy of the reactants.
Explanation:
the the change is enthalpy is negative, and heat is released to the surroundings.
Answer:
The effect is the increasing of the molar concentration.
Explanation:
When you standarize a solution of NaOH with KHP you are establish its molar concentration (That is the amount of moles of NaOH per liter of solution).
If you evaporated some water of the solution, you are increasing its concentration because volume is decreasing doing the amount of moles per liter increasing.
It's not really possible to tell longitudinal vs. transverse in this image as given. However, we can say that the waves labeled A are high-frequency (short wavelengths) while the waves labeled B are low-frequency (long wavelengths). So, this third answer choice would be correct here.
They both represent equations, they both use lines
The glowing splint in the reaction of hydrogen gas and oxygen gas to form water provides the activation energy for the reaction.
<h3>Reaction of hydrogen gas and oxygen</h3>
A chemical reaction involves the combination of two or more substances to yield a new substance which is different from the starting materials. It may also involve the break up a substance.
Since energy is required for a chemical reaction to take place, the glowing splint in the reaction of hydrogen gas and oxygen gas to form water provides the activation energy for the reaction.
