Answer:

The formal charge on H atom in HF = 0

Explanation:

Formal charge is the charge on an atom when all the chemical bonds that are formed by that atom are formed by equal sharing of electrons.

<u>The formal charge of an atom is given by the equation:</u>

Formal charge = [Total number of valence electrons in the ground state (n)] - [Number of non-bonding valence electrons on atom in a molecule (N)] - [Number of shared or bonding electrons (B) ÷ 2]

<u>To find out the formal charge on hydrogen (H) atom in H-F molecule:</u>

For H atom in ground state: n = 1

For H atom in H-F molecule: N = 0 and B = 2

Since, Formal charge = n - N - (B ÷ 2)

So, The formal charge on H atom in HF = 1 - 0 - (2÷ 2) = 1 - 1 = 0

<em><u>Therefore, the formal charge on H atom in HF = 0</u></em>

mash [69]

Yes, it will be worthwhile to investigate finding a catalyst to use in this reaction under standard conditions because it is negative.

<h3>What is a Catalyst?</h3>

This is a substance which speeds up the rate of a chemical reaction by lowering the activation energy.

ΔG being negative indicates a a slow reaction which is why a catalyst under standard conditions should be used.

alisha [4.7K]

Remark

The balance numbers in front of the chemicals tell you how to set up the proportion to solve your question

For every 2 moles Na only 1 mole of Cl2 is required.

Equation

2 moles Na:1 mole Cl2 :: x moles Na:4 moles Cl2

Solution

2/1 = x/4                 Cross multiply

2*4 = x*1

8 = x

Conclusion

8 moles of Na will be used. <<< Answer

What is the base metric unit for measuring volume?
uranmaximum [27]
I got this idk if it's correct: For measuring large distances, the kilometer (103 or 1000 meters) is often used. The basic unit of volume in the metric system is the liter (l). The most common derived unit is the milliliter (ml) (10-3 or 1/1000 of a liter). The volume of a milliliter is equal to the volume of a cube 1 centimeter per side.
