Answer:
334.08 g
Explanation:
87 proof = 43.5%
in 1L of liquid there is 43.5% alcohol/ethanol
1L (43.5/100) = 0.435 L alcohol
we want density in g/L because that's the volume u have
density 0.798 g/mL = 798 g/L
multiply the volume of alcohol by its density to get grams
0.435 L(798 g/L) = 334.08 g
Answer:
20
Explanation:
protons and nucleons have an atomic weight of 1
electrons carry no weight
hence the weight of the atom is
10 + 10 = 20
No It is not correct.
Correct oxidation number of hydrogen in NaH,H2 and H2S are:
- Let x be the Oxidation state of ’H’ by oxidation state rule.
x+1 =0 (Sodium has +1 Oxidation state )
x=−1
Therefore, -1 is oxidation number of Hydrogen in NaH.
- The oxidation number of an element's atom in its standard state is zero. As a result, the oxidation number for H2 is zero.
- The hydrogen oxidation number in H2 is +1. As a result, that hydrogen atom can be reduced to lower oxidation states of hydrogen, such as 0 and -1. However, because +1 is the highest oxidation state of hydrogen, the hydrogen atom cannot be reduced any further.
<h3>What is oxidation number?</h3>
In simple terms, the oxidation number is the number assigned to elements in a chemical combination. The oxidation number is the number of electrons that atoms in a molecule can share, lose, or gain when forming chemical bonds with atoms of a different element.
