That is the definition of pressure. The amount of force exerted over a certain area: N/m^2 (Newtons per square metre).
Hiii,so the problem is ♀️
Answer: A wave
Explanation:
Because it’s the one that’s cause the new medium to go between the two media.
Answer:
pH=2.34
Explanation:
HBr -> H + Br
The dissociation it's complete, for that reason the concentration of the products is the same of HBr
[H+]=[Br-]=0.00234 M
pH= - log (0.00234)=2.34
Number of moles = mass of product / molecular mass
=mass of product (MgO) / 40.3
Since the mass of MgO is not given in the question, the correct answer choice cannot be given. However, proceeding witht eh above formula will enable you to find the correct number of moles given the mass of MgO.
