False-  Strontium will need to lose two valence electrons to make its second-highest energy level be its valence energy level (being filled with an octet of electrons) and possess a more stable electronic arrangement. In order to do so, a single oxygen atom must be available, as both strontium valence electrons will be gained by the single oxygen atom.

Answer:

False

Explanation:

When this ionic bond is completed it will not have the result being presented in the question.

The answer to the question is 0.8055 as the answer should not include units in it.

Molarity (M) = n/v

n = moles of solute

v = liters of solution

According to question

1% solution → 1 gram of solute for 100 milliliters of solution

2% solution → 2 grams of solute for 100 milliliters of solution

6% NaClO solution → 6 grams of NaClO (solute) for 100 milliliters of solution

Molar mass of NaClO = (22.98 + 35.5 + 16)g/mol = 74.48 g/mol

Atomic mass of Na = 22.98 g/mol

Atomic mass of Cl = 35.5 g/mol

Atomic mass of O = 16 g/mol

1 mol NaClO = 74.48 grams NaClO

74.48 grams NaClO = 1 mol NaClO

6 grams NaClO = (1×6) / 74.48 mole = 0.08055 mole

As unit molarity is mole / liter

So 100 milliliters = 0.1 liters

1 liter = 1000 milliliters

100 milliliters = 100/1000 liters = 0.1 liters

Molarity of NaClO = moles of solute (NaClO) / liters of solution or volume of solution

Molarity of NaClO = 0.08055 / 0.1 mole/L =  0.8055 mole/L

As in question it is mentioned that 'Do not type units into your answer'

So, Molarity of NaClO in clorox bleach = 0.8055

Thus we find out the value of molarity of NaClO in Clorox bleach which came out to be 0.8055 as we dont have to give the answer with units.

A reaction that produces great heat for welding and incendiary bombs
Anna11 [10]

Answer:

7.19 g of Fe2O3 will produce 0.092 mole of iron

Explanation:

One mole of Fe2O3 reacts with 2 mole of Aluminum to produce one mole of Al2O3 and 2 mole of iron.

Mass of one mole of Fe2O3 = 159.69 g/mol

Thus, 159.69 g/mol of Fe2O3 produces two mole of Fe

7.19 g of Fe2O3 will produce

\frac{2}{156.9} * 7.19\\= 0.092moles of iron
