Which statement best describes the polarity of SCL4F2?

Chemistry
1 answer:
kotegsom [21]4 years ago
3 0

Answer: Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.

Explanation:

Polarity is when the electric charge that is leading to a molecule is being separated.

The polarity of SCL4F2 can either be polar or non polar and this depends on the arrangement of outer atoms. It is the arrangements of these outer atoms that'll help in the determination of its polarity.

ANEK [815]
Because we are moving at a constant rate (seeing as we're on earth and the earth is spinning) but the moon does not spin as it revolves around us, therefore we only see the one side of it.

Oxygen has 6 valence electrons. How many electrons does an atom of oxygen need to become stable?
SOVA2 [1]

Answer:

Two electrons

Explanation:

According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.

Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.

In a constant-pressure calorimeter, 55.0 mL of 0.340 M Ba(OH), was added to 55.0 mL of 0.680 M HCI. The reaction caused the temp
Brut [27]

Answer:

Ba(OH)2 + 2 HCl → BaCl2 + 2 H2O

The reactants are present in equimolar amounts, so there is no excess or limiting reactants.

(0.0500 L) x (0.600 mol/L HCl) x (2 mol H2O / 2 mol HCl) = 0.0300 mol H2O

(4.184 J/g·°C) x (50.0 g + 50.0 g) x (25.82 - 21.73)°C = 1711.256 J

(1711.256 J) / (0.0300 mol H2O) = 57042 J/mol = 57.0 kJ/mol H2O
