Answer: 1.348 ×10^23 atoms
Explanation:
Given that volume = 1.00L
At standard condition, the volume of a gas is 22.4L/mol (at S.T.P)
Volume = mole /volume at STP
1 = mole/22.4
Mole= 22.4mol.
Also
Mole = number of atoms /Avogradro constant
Where avogrado's constant = 6.02×10²³
22.4 = number of atoms/6.02×10²³
Number of atoms = 1.348×10^25atoms
Hi!
In collision theory, for a chemical reaction to occur - there must be <em>sufficient </em>energy to break down chemical bonds.
We call this the activation energy, as it's the energy needed to <em>activate </em>a chemical reaction!
Hopefully, this helps! =)
Answer:
then it would still be 101.3
Explanation: because if it's constant that means it remained still
Answer:
false
explanation:
it is possible to lower the amount of activation energy required in a system. the process of speeding up a reaction by reducing its activation energy is known as catalyst.
Answer : The value of 
of the generic salt is, 
Explanation :
As we are given that, a solubility of salt is, 8.70 g/L that means 8.70 grams of salt present in 1 L of solution.
First we have to calculate the moles of salt 
Molar mass of 
= 345 g/mol
Now we have to calculate the concentration of 
The equilibrium chemical reaction will be:
Concentration of 
= 
Concentration of 
=
The solubility constant expression for this reaction is:
![K_{sp}=[A^{2+}][B^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BA%5E%7B2%2B%7D%5D%5BB%5E-%5D%5E2)
Now put all the given values in this expression, we get:
Thus, the value of of the generic salt is,
