Answer:
C
Explanation:
A gas is a state of matter that has no fixed shape and no fixed volume gases have lower density than other states of matter such as solids and liquids.
Answer:
The entity that decreases is the Weight.
Explanation:
Every object on the surface of the earth is usually pulled downwards by the action of gravity. The force or weight is W = mg
Now, the farther one gets away from the surface of the earth by climbing a mountain, the further the person is from the Earth's centre of gravity.
We know that the formula for Force of gravity away from the Earth's surface is given by;
F_g = GM1M2/r²
So the greater the distance, the lesser the gravitational force.
Now, the gravitational force equals the weight of the individual.
Thus, the entity that decreases is the Weight of the individual.
Carbon has a tendency to form covalent bonds.
Because of the fact that NaBr is an ionic bond, the bond is harder to break, therefore it needs more heat (or a higher temperature) to break it.
Rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122M.
A rate law indicates the rate of a chemical response depends on reactant concentration. For a response inclusive of the price regulation commonly has the form rate = ok[A]ⁿ, in which okay is a proportionality constant known as the fee regular and n is the order.
The charge of a chemical response is, perhaps, its maximum crucial asset because it dictates whether or not a reaction can arise all throughout an entire life. knowing the charge regulation, an expression concerning the price to the concentrations of reactants can assist a chemist to modify the response conditions to get an extra suitable rate.
half-life is the time taken for the radioactivity of a substance to fall to 1/2 its authentic cost whereas implies existence is the common life of all the nuclei of a particular risky atomic species.
