This is what the lewis structure looks like
so Each carbon atom has 4 unpaired electrons available for bonding.

Each of the 3 chlorine atoms has a single unpaired electron available for bonding.

The hydrogen has a single electron available for bonding.

This results in carbon forming 4 single covalent bonds.

The systematic name is trichloromethane.

2FeCl3 + MgO -> Fe2O3 + 3MgCl2 Convert 3.00 moles of MgO to moles of Fe2O3

71.8 g of iron (III) oxide (Fe₂O₃) were produced from 3 moles of magnesium oxide (MgO).

Explanation:

We have the following chemical reaction:

2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂

We see from the chemical reaction that 3 moles of magnesium oxide (MgO) will produce 1 mole of iron (III) oxide (Fe₂O₃).

number of moles = mass / molar weight

mass = number of moles × molar weight

mass of Fe₂O₃ = 1 × 71.8 = 71.8 g

How many molecules of ethane ( C2H6) are present in 0.197g of C2H6?

Brut [27]

Answer:

3.945 x 10²¹ molecules

Explanation:

Firstly, we need to calculate the no. of moles using the relation:

n = mass/molar mass = (0.197 g)/(30.07 g/mol) = 6.55 x 10⁻³ mol.

It is known that every 1.0 mol of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).

∴ 0.197 g of C₂H₆ will contain = (6.55 x 10⁻³ mol)(6.022 x 10²³) = 3.945 x 10²¹ molecules.

Tema [17]

Answer:

45.13 psi

Explanation:

Assuming the volume does not change

P1/T1 = P2/T2 T must be in Kelvin

40/(273.15) = P2/(273.15 + 35) P2 = 45.13 psi
