Answer: The standard state refers to 1 atm and 
.
Explanation:
It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.
So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of then it known as standard state of substance.
Thus, we can conclude that standard state refers to 1 atm and .
Answer and explanation :
DIFFERENCE BETWEEN HOMOGENEOUS AND HETEROGENEOUS MIXTURE :
- In homogeneous mixture the component which are present in the mixture all are in the same proportion whereas in heterogeneous mixture the component which are present in the mixture don't have the same proportion
- We can not pick out the component of homogeneous mixture but in heterogeneous mixture we can pick out the components from the mixture
- Example of homogeneous mixture is water, oil ,water sugar solution, milk blood etc. And example of heterogeneous mixture is solution of sand and water ,concrete etc.
Answer: Dinitrogen pentoxide
Explanation:
Answer:
The catalyzed reaction will take 1,41 s
Explanation:
The rate constant for a reaction is:
Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:
Replacing:
That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:
4,50x10⁻⁸ years×

72g
Explanation:
Given parameters:
Number of moles of LiOH = 3moles
Unknown:
Mass of LiOH = ?
Solution:
A mole of substance is a unit used to make quantitative measures in chemistry.
It is the amount of substance that contains the avogadro's number of particles.
The mole is related to mass using the expression below;
Mass of a substance = number of moles x molar mass
Molar mass of LiOH = 7 + 16 + 1 = 24g/mol
Mass of LiOH = 3 x 24 = 72g
