A catalyst is a chemical that increases the rate of a chemical reaction without itself being changed by the reaction. The fact that they aren't changed by participating in a reaction distinguishes catalysts from substrates, which are the reactants on which catalysts work. Enzymes catalyze biochemical reactions.
Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as:
Energy = mCΔT2520= 10.0(C) (70.0 - 10.0)C = 4.2 J/ kg K
Answer: The nuclear equation is
.
Explanation:
A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.
For example, ![^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma](https://tex.z-dn.net/?f=%5E%7B180%7D_%7B173%7DTl%20%5Crightarrow%20%5E%7B180%7D_%7B173%7DTl%20%2B%20%5E%7B0%7D_%7B0%7D%5Cgamma)
Here, energy is radiated in the form of gamma radiation.
Thus, we can conclude that the nuclear equation is
.

Answer:
Electrons are trapped inside the atom because of the attraction forces with positively charged protons that are found in the nucleus.
