Answer:

The charge will be "-1".

Explanation:

In a neutral atom there are protons and neutrons in the nucleus and the same number of electrons (as of protons) in the outer shells.

As given that there are four protons and 5 electrons, it means the given atom is not neutral.

An atom may have lesser number of electrons than that of protons or it may have more number of electrons.

If an atom has less number of electrons, it will carry positive charge

If an atom has more number of electrons, it will carry negative charge.

So the total electric charge on the atom will be "-1"

Neutrons are uncharged
proton (+4) + electrons (-5)= -1

Molarity =  Moles/Liter

Use the molecular atomic mass of NaCl to convert from grams to moles.
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol ,
so NaCl = 23 + 35.5 = 58.5 g/mol

multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl

over 1 Liter is just 1.3 M NaCl
Hope this helps!

Which is true when a reaction has reached equalibrium
Serggg [28]
The answer should be: <span>D. The reaction rate is equal in both directions

In the equilibrium state, the rate of reaction to the right is same as the reaction to the left. Because of this, the concentration of the reactant and product will be kept same.
It might seem like the reaction is stopped because there is no change in the concentration, but it wasn't.  Adding a reactant or product will break the equilibrium state.</span>

A positively charged substance is brought near the ion. What will most likely happen and why
d1i1m1o1n [39]

<u>Answer:</u> It repels positive ion and attracts negative ion.

<u>Explanation:</u>

There are 2 types of ions:

1. Cations: These ions are positively charged ions which are formed when a substance looses electrons.

2. Anions: These ions are negatively charged ions which are formed when a substance gains electrons.

It is known that, like charges repel each other and unlike charges attract each other.

As, it is given that the substance is positively charged, so it will attract anion and repel cation.
