Oduvanchick [21]2 years ago
4 0

The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.

The angle that exists among two covalent bonds that come from the same atom is known as a bond angle.

When there have four bonds and no lone pairs, the tetrahedral geometry occurs. Given that many molecules would adopt this geometry, it represents one of the most significant and prevalent geometries. For example,  CH_{4} assumes a tetrahedral geometry. Tetrahedral molecules have a bond angle of around 109.5°.

Therefore, The typical bond angles (in degrees) in molecules with 4 electron groups will be <u>109.5 degrees</u>.

Fe2O3+2Al=Al2O3+2Fe
True [87]
We determine the limiting reactant by using the moles present in the equation and the actual moles.
According to equation, ratio of Fe₂O₃ : Al = 1 : 2
Actual moles of Fe₂O₃ = 187.3 / (56 x 2 + 16 x 3)
= 1.17
Actual moles of Al = 94.51 / 27
= 3.5
Fe₂O₃ is limiting. Fe₂O₃ required:
(moles Al)/2 = 3.5/2 = 1.75
Moles to be added = 1.75 - 1.17
= 0.58
Mass to be added = moles x Mr
= 0.58 x (56 x 2 + 16 x 3)
= 92.8 grams

Answer:

Mass = 5.56 g

Explanation:

Given data:

Mass of Cl₂ = 4.45 g

Mass of NaCl produced = ?

Solution:

Chemical equation:

2Cl₂ + 4NaOH     →   3NaCl + NaClO₂ + 2H₂O

Number of moles of Cl₂:

Number of moles = mass/molar mass

Number of moles = 4.45 g/ 71 g/mol

Number of moles = 0.063 mol

Now we will compare the moles of Cl₂ with NaCl.

                  Cl₂         :         NaCl

                    2          :          3

                 0.063      :        3/2×0.063 =0.095 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 0.095 mol × 58.5 g/mol

Mass = 5.56 g
