Answer: Option (d) is the correct answer.

Explanation:

A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.

For example, $CH_{4}$ has tetrahedral geometry.

Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.

AURORKA [14]

a) Answer:

Number of molecules in 1 mole

Explanation:

a) Whether we take any of the substance among all three of the given substances they will have the same number of molecules in 1 mole of the substance is considered and the value for this will be $6.023 x 10^23$

b) Answer:

In the given question mass of the substance which is greatest is asked for one mole and we also know that mass of one mole is given by molar mass.

Explanation:

b) It is known that $31.98g/mol$ is the molar mass for oxygen which is greater than that of hydrogen while fluorine has a molar mass of $38.0 g/mol$ which on comparison shows that, it is the highest amongst all three.

If a bottle of olive oil contains 1.4 kg of olive oil, what is the volume, in milliliters ( mL ), of the olive oil?

Serhud [2]

We know that density of olive oil = 0.93 g/mL

Given that mass of olive oil = 1.4 kg or 1400 g because 1000 g = 1.0 kg

From the definition of density;

Volume = mass/ density

= 1400 g/ 0.93 g/mL

=1505 mL

When oxygen is depleted, the citric acid cycle stops. What could we add to the system to restore citric acid cycle activity (oth

Hoochie [10]

Answer:

NAD+, FAD.

Explanation:

The citric acid cycle is popularly known as the Kreb's cycle. The cycle involve the oxidation of acetyl-CoA to produce energy. The Kreb's cycle is a chemical process that produces produces two carbon dioxide molecules,NADH,FADH2 and one ATP.

When oxygen is depleted, the citric acid cycle stops, apart from oxygen NAD+ and FAD could be added to the system to restore citric acid cycle activity. NAD+ acts as an electron acceptor.

Citric acid cycle/Kreb's cycle is an aerobic process that occurs in the mitochondria and produces thirty-six(36) ATPs.
