The atomic number of an atom (Z) is equal to the number of protons.
The mass number of an atom (A) is equal to the number of protons plus the number of neutrons (N), i.e. A = Z + N
Therefore, N = A - Z = 7 - 3 = 4.
So, this neutral lithium atom has 4 neutrons.
Answer: 4.
Answer:
I think it's b.
Explanation:
Because solubility increased by temperature.
Pretty sure it’s B, it increases then remains constant
Hope this help
The rate of change of (g)=0.024M/s when the rate of change of is – 0.012 M/s.
<h3>What is the rate of reaction?</h3>
Reaction rate, in chemistry, is the speed at which a chemical reaction proceeds.
→
Rate = \frac{-dcs_2}{dt} =\frac{-do_2}{dt} =\frac{+dco_2}{dt} =\frac{1dso_2}{dt}
Given:
The rate of change of (g)=0.024M/s
Hence, the rate of change of (g)=0.024M/s

Answer:
B) extensive/intensive
Explanation:
An extensive property is a property of a component or system that is a function of the whole component. It is a kind of property that changes if the material is added or subtracted to the component.
An intensive property is a property of a material that does not depend on the amount or shape of the material, a property of a material at a specific point in time.
From the question, we can conclude that heat is an example of extensive property and temperature is an example of an intensive property.
