right 5 possible mole ratios
Answer:
Here's what I get
Explanation:
I think this may be the equation you intended to write:
C₃H₅(OH)₃ + 3HCl ⟶ C₃H₅Cl₃ + 3H₂O
The mole ratios are the ratios of the coefficients in the balanced equation.
Here are some of the possible molar ratios.
(2) parts per million
(3) grams per Kelvin
(4) joules per gram
Answer:
(2) parts per million
Explanation:
Concentration of a solution can be expressed in terms of parts-per-million (ppm).
ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.
It is expressed as:
1 ppm = 1 mg / L
1 ppm = 1 mg/ Kg
B.Oxygen
C.Hydrogen
D.Iron

Explanation: its right if you go to k12
(2) 0.0005 u
(3) 1 g
(4) 0.0005 g
The mass of a proton is approximately 1 atomic mass unit (u). Among the options provided, the correct one is (1) 1 u. The mass of a proton is a known constant and does not change.
The mass of a proton is approximately 1 atomic mass unit (u). Atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights. Given the options provided, the correct answer would be (1) 1 u. The other options are not accurate because a proton's mass is a known constant in physics and chemistry and does not correspond to those values. It's important to remember that the mass of a fundamental particle like a proton remains constant and does not change.
