Carbonic acid's chemical formula is H2CO3. Its decomposition to water (H2O) and carbon dioxide (CO2) is represented by the equation:
H2CO3(g) → H2O(l) + CO2(g)
Hey there!
Volume in mL :
1.25 * 1000 => 1250 mL
Density = 0.921 g/mL
Therefore:
Mass = density * volume
Mass = 0.921 * 1250
Mass = 1151.25 g
Answer:
Option-B (k) is the correct answer.
Explanation:
As we know the rate of reaction is given as;
Rate = k [A]ˣ
Where;
Rate = Rate of Reaction
k = rate constant
[ ] = concentration of A
x = order of reaction
So, from this equation we found that rate of reaction depends upon concentration and rate constant (k).
Now,
The rate constant is as follow,,
k = Ae^(Ea/RT)
This equation is known as Arrhenius Equation, according to this equation rate constant depends upon Temperature and Activation energy. Greater the temperature greater is the rate constant and hence greater is the rate of reaction. Or smaller the activation energy greater is the rate constant and vice versa.
Answers:
Fission breaks apart nuclei
Fusion puts them together.
======================================================
Explanation:
The term "fission" is related to the term "fissure" which means "a cut or divide", often describing a geologic feature of the earth (eg: a crack in the rock).
Fusion is the idea of putting things together, which is the opposite of fission. The term doesn't have to apply to nuclear fusion. It could be something like the fusing of two ideas to create one new idea.
An increase in pressure increasing the billing point is an example of a physical property.
- The term "boiling point" describes the temperature at which a liquid, which is being boiled, changes from a liquid to a vapor when its pressure equals that of its environment.
- Physical changes are those that take place when a material's structure is the same both before and after the change.
- When a substance is changed into another chemical substance, this is known as chemical transformation.
- When describing the state of a physical system, a substance's physical qualities are those that can be measured.
- A substance's characteristic that is seen in a chemical reaction is referred to as a chemical property.
As it demonstrates the physical state, the increase in pressure with boiling point is an example of a physical property.
