Answer:

n_{CO_2}=0.119molCO_2

m_{CO_2}=5.24gCO_2

Explanation:

Hello.

In this case, since the chemical reaction:

NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2O+CO_2

And 10.0 grams of sodium bicarbonate (molar mass = 84 g/mol) are reacting in a 1:1 mole ratio with the yielded carbon dioxide, those moles and grams turn out:

n_{CO_2}=10.0gNaHCO_3*\frac{1molNaHCO_3}{84gNaHCO_3} *\frac{1molCO_2}{1molNaHCO_3} =0.119molCO_2

And the mass by considering the molar mass of carbon dioxide to be 44 g/mol:

m_{CO_2}=0.119molCO_2*\frac{44gCO_2}{1molCO_2} \\\\m_{CO_2}=5.24gCO_2

Best regards.

How many ATOMS of boron are present in 3.61 grams of boron trifluoride ?
Delvig [45]

Hi there!

\large\boxed{3.203 *  10^{22} atoms}

We can use the following conversions to solve:

Total mass --> amount of mols --> amount of atoms (Avogadro's number)

Begin by calculating the amount of boron trifluoride in 3.61 grams:

3.61 g * (1 mol BF₃ / 67.8 g) ≈ 0.0532 mol BF₃

Use avogadro's number to convert:

0.0532 mol * 6.02× 10²³atoms / 1 mol = 3.203 × 10²² atoms

To make a Br2 bond, how many total valence electrons are required?
lapo4ka [179]

Answer:

2. 14

Explanation:

To form Br₂ bond, a total of 14 electrons are needed.

Bromine is an element in the 7th group on the periodic table. It has 7 valence electrons.

  • In forming the bromine gas, the two atoms of bromine shares 7 electrons each.
  • These electrons are from their outermost shell.
  • The outermost shell is the valence shell.
  • So, two atoms donating 7 electrons gives 14 electrons.
