Explanation:
Water has a formula which represents two hydrogen atoms are attached to one oxygen atom. Therefore, the formula of water is .
Salt is also known as sodium chloride. Its formula represents that one sodium atom is attached to one chlorine atom, therefore, its formula is NaCl.
Carbon dioxide has a formula which represents one carbon atom is attached to two oxygen atoms. Therefore, its formula is .
Methane has a formula which represents one carbon atom is attached to four hydrogen atoms. Therefore, its formula is .
Thus, we can conclude that is water,
is carbon dioxide, NaCl is salt, and
is methane.
Answer:
Explanation:
Given the moles, we are asked to find the mass of a sample.
We know that the molar mass of methanol is 32.0 grams per mole. We can use this number as a fraction or ratio.
Multiply by the given number of moles, which is 2.0
The moles of methanol will cancel each other out.
The denominator of 1 can be ignored.
Multiply.
There are 64 grams of methanol in the sample.
Formal Charge on Nitrogen is "Zero".
<h3>Explanation:</h3>Formal Charge on an atom in molecules is calculated using following formula;
Formal Charge = [# of Valence e⁻s] - [e⁻s in lone pairs + 1/2 # of Bonding e⁻s]
As shown in attached picture of Hydroxylamine, Nitrogen atom is containing two electrons in one lone pair of electrons and six electrons in three single bonds with two hydrogen and one oxygen atom respectively.
Hence,
Formal Charge = [5] - [2 + 6/2]
Formal Charge = [5] - [2 + 3]
Formal Charge = 5 - 5
Formal Charge = 0 (zero)
Hence, the formal charge on nitrogen atom in hydroxylamine is zero.
