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

How much mass do 3.4 moles of silver contain?
tensa zangetsu [6.8K]

367.2 g of silver

Explanation:

To find the mass of a substance knowing the number of moles we use the following formula:

number of mole = mass / molecular weight

In the case of silver we use the atomic weight of 108 g/mole.

mass = number of moles × molecular weight

mass of silver = 3.4 moles × 108 g/mole

mass of silver = 367.2 g

If 250 milliliters of Calcium Hydroxide is titrated with 345 milliliters of 0.75 molarity hydrobromic acid, what is the concentr
Bingel [31]
The balanced neutralization reaction here is:

Ca(OH)2 + 2HBr --> 2H2O + CaBr2

Notice that two moles of Her are required to neutralize every one mole of Ca(OH)2. This means that for however many moles of Her reacted, HALF as many moles of Ca(OH)2 reacted as well.

Moles of HBr reacted = 0.75 M x 0.345 L = 0.259 mol

Moles of Ca(OH)2 reacted = 0.259 mol / 2 = 0.130 mol

Concentration of Ca(OH)2 = 0.130 mol / 0.250 L = 0.52 M
