Answer:
A. It is the work done when a force of 1 newton is applied to an object for a distance of 1 meter
Explanation:
Answer:
False
Explanation:
While chemical reactions can proceed in the forward direction , they can in fact also proceed in the backward direction too. The direction they would proceed depends majorly on the state of chemical equilibrium at that particular time for that particular chemical reaction.
It should be known that when a chemical reaction proceeds in the forward way, more products are formed and the reactants are used up. If however, the chemical reaction proceed in the backward way, more reactants are formed and the products are used up.
A practical example is in the case of an exothermic reaction. This is one in which heat is released to the surroundings as a result of the reactants being at a higer energy level compared to the product. Now, depending on the prevailing equilibrium constraint, the reaction could proceed forward or backward.
If for example, the temperature is decreased, this is a constraint being applied to the equilibrium state. The chemical reaction would take a shift and will favor the forward reaction and more of the products will be formed. And also of the temperature is increased, it is the backward reaction that is favored
Answer:
24.5
Explanation:
15/6.3 => 2.38 half lives passed.
.5^2.38 => 0.19198 decimal representation of the percentage that is left over after 2.38 half lives have passed.
0.19198 *128 = 24.5 mg of the material remaining.
Answer:
Ki = 30atmL
Kf = 30atmL
Explanation:
The following data were obtained from the question:
V1 (initial volume) = 15.0L
P1 (initial pressure) = 2atm
V2 (final volume) = 7.5L
P2 (final pressure) = 4atm
Ki (initial constant) =?
Kf (final constant) =?
Boyle's law states that PV = K
Ki = P1V1
Ki = 2 x 15 = 30atmL
Kf = P2V2
Kf = 4 x 7.5 = 30atmL
Since Ki and Kf are the same, the gas obey Boyle's law
No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
