Answer:
60
Step-by-step explanation:
Set up a ratio problem
15/25 = 36/x
15x = 900
x = 60
Answer:
Step-by-step explanation:
5(-5)-2=-27
5(-2)-2= -12
5(1)-2=3
5(2)-2=8
5(3)-2=13
x g(x)
-5 -27
-2 -12
1 3
2 8
3 13
The expression we have is:

And we are given some values for x and y:

The first step will be to substitute the given values into the expression:

The next step is to solve 4^2 which is equal to 16:

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

Solving this final multiplication we get the result:

This gives:


Solving (d): Probability of 1 or 2 CDs
Here, we consider:

This probability is calculated as:

This gives:


Solving (e): Probability of more than 2 CDs
Here, we consider:

This probability is calculated as:

This gives:


Answer:
The reactant that acts as an acid, by contributing an H⁺ ion to create H3O+ in the chemical equation is C₆H₅OH.
Step-by-step explanation:
According to Brønstend-Lowry, an acid is a substance that transfer a proton (hydrogen cation, H⁺) to a base, forming a base conjugate for the first and an acid conjugate for the second.
From the following reaction:
C₆H₅OH(aq) + H₂O(l) → C₆H₅O⁻(aq) + H₃O⁺(aq)
We have that the C₆H₅OH transfer a proton to the water to form its conjugate base C₆H₅O⁻ and the conjugate acid of water H₃O⁺. Hence, the C₆H₅OH is the acid and the water is the base.
Therefore, the reactant that acts as an acid, by contributing an H⁺ ion to create H3O+ in the chemical equation is C₆H₅OH.
I hope it helps you!
