Answer: An acid contains more hydrogen ions than hydroxide ions.
Explanation:
An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton 
donors when they have high concentration of hydrogen ions.
A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton acceptors when they have low concentration of hydrogen ions.
Hence, an acid is contains more hydrogen ions than hydroxide ions.
The rays of the sun will go directly to the trees, then
trees take up light that absorbs light energy which converting light to
chemical potential energy kept in chemical bonds. And when the trees cut into
woods and burnt it, it will convert to thermal energy.
I am assuming that the problem ask for the pressure in
the system. To be able to calculate this, we first assume that the system acts
like an ideal gas, then we can use the ideal gas equation to find for pressure
P.
P V = n R T
where,
P = Pressure (unknown)
V = 0.17 m^3
n = moles of lng / methane
R = gas constant = 8.314 Pa m^3 / mol K
T = 200 K
We find for the moles of lng. Molar mass of methane = 16
kg / kmol
n = 55 kg / 16 kg / kmol
n = 3.44 kmol CH4 = 3440 mol
Substituting all the values to the ideal gas equation:
P = 3440 mol * (8.314 Pa m^3 / mol K) * 200 K / 0.17 m^3
P = 33,647,247 Pa
<span>P = 33.6 MPa</span>
Answer:
Try looking for some kind of answer that has to do with .61904
Explanation:
52 g x 1 mol/ (molar mass of aluminum fluoride) 84 g = .619047619
Sorry if this is wrong but that's my best guess
Answer would be A)the atom
