From the given balanced chemical equation,
CO2 + 2LiOH --> Li2CO3 + H2O
we can conclude that for every 2 moles of LiOH, we need a mole of CO2. Calculate first the number of moles of CO2 by dividing the given mass by the molar mass giving us an answer of 0.58 moles. Using proportionality,
0.58 / x = 1 / 2
The value of x is equal to 1.16 moles.
Answer:
B because you will feel the moons gravitational force and not earths

Explanation:
The valence electrons of an element is usually determined by its atomic number. The valence elctrons are the electrons that have the highest energy level.
Fluorine has 7 valence electrons in the ground state.
need 0.500 x 0.125 = 0.0625 moles of NaOH. The molecular weight is 23+16+1 = 40, so 0.0625 x 40 = 2.5 grams will do the trick.
The correct answer is A. Ethanol is alcohol; gasoline is fuel.
