Answer:
See explanation
Explanation:
Number of protons = 28
Number of neutrons = 28
Mass of each proton = 1.007277 amu
Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu
Mass of each neutron = 1.008665 amu
Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu
mass defect of nickel-56 = 0.4667 amu
Binding energy = Δmc^2
Binding energy = 0.4667 *(3 * 10^8)^2
Binding energy =4.2 * 10^16 J
Binding energy per nucleon = 4.2 * 10^16 J/56
Binding energy per nucleon = 7.5 * 10^14 J
Answer:
the first one which is A
Explanation:
the burning of fossil fuels causes both air pollution and water pollution
Answer:
B. Reese's yard
Explanation:
Because Reese's yard is full of rocks, rock's don't absorb water, while Chris' yard is only soil, which will make his yard absorb water quicker.
Answer:- Third option is correct, relative strength of orange juice to pure water is 1000 times
Solution:- pH is a way to represents the strength of the acids. Lower is the pH higher is the acid strength and higher is the pH lower is the acid strength. So, we could say that acid strength is inversely proportional to the pH.
From given pH value, we calculate the hydrogen ion concentration and then compare the hydrogen ion concentrations of the two acids to find out the relative strength.
for orange juice = and for pure water it is .
So, the relative acidity of orange juice compared to pure water =
= 1000
So, third option is correct, the relative strength of orange juice to pure water is 1000 times.
