Hydrogen bonding takes place between hydrogen and either nitrogen, oxygen, or fluorine. Carbon has an electronegativity similar to hydrogen's, and will not hydrogen bond with hydrogens in other molecules. Only molecules with -OH, -FH, or -NH groups can form hydrogen bonds.

lawyer [7]

Answer:

Lipids.

Explanation:

Steroids are known as the type of lipid which consists of 4 rings of carbon atoms. All steroids have 1 five-sided carbon ring and a 3 six-sided carbon ring. They are works as a hormone in the body and secreted by the ovaries and testes.

Steroids differ in functional groups. When this functional group attached to the steroid ring it gives steroids with a different function. They are composed of largely carbon, and hydrogen atoms. They are insoluble in nature in water.

Which of the following should have the largest Henry's law constant (kH) in water?

Ostrovityanka [42]

Answer: Option (B) is the correct answer.

Explanation:

It is known that Henry's law is a relation between the concentration of a gas in a liquid (solubility) and the pressure it exerts on the surface of the liquid.

According to Henry's law, the pressure of a gas is directly proportional to the solubility of the gas in a liquid.

Henry's constant is represented by the symbol $K_{H}$ . And, mathematically it is represented as follows.

P = $K_{H}C$

where, P = pressure and C = solubility

As the pressure for the given species is the same. Hence, the standard values of solubility of the given species is as follows.

Gas Solubility

Ar $3.025 \times 10^{-5}$

CO $2.095 \times 10^{-5}$

Xe $10.519 \times 10^{-5}$

$CH_{3}CH_{3}$ $4.556 \times 10^{-5}$

$CO_{2}$ $8.21 \times 10^{-4}$

As, Henry's constant is inversely proportional to the solubility. Hence, more is the value of solubility lesser will be the value of Henry's constant.

Thus, we can conclude that out of the given options CO have the largest Henry's law constant ( $K_{H}$ ) in water.

In the first 15.0 s of the reaction, 1.7×10−2 mol of O2 is produced in a reaction vessel with a volume of 0.440 L . What is the

Step2247 [10]

Answer:

$Rate=2.57x10^{-3}\frac{M}{s}$

Explanation:

Hello,

In this case, for the reaction:

$2N_2O(g) \rightarrow 2N_2(g)+O_2(g)$

We can easily compute the average rate by firstly computing the final concentration of oxygen:

$[O_2]=\frac{0.017mol}{0.440L}=0.0386M$

Then, we compute it by using the given interval of time: from 0 seconds to 15.0 seconds and concentration: from 0 M to 0.0386M as oxygen is being formed:

$Rate=\frac{0.0386M-0M}{15.0s-0s}\\ \\Rate=2.57x10^{-3}\frac{M}{s}$

Regards.

Find the mass of calcium oxide produced from the thermal decomposition of 50 g of calcium carbonate.

anastassius [24]

Answer:

28 g

Explanation:

The chemical equation of the reaction is given below:

CaCO₃ (s) ⇒ CaO (s) + O₂ (g)

From the chemical equation, 1 mole of CaCO₃ produces 1 mole of CaO.

So, we find the number of moles,n of CaCO₃ in 50 g from

n = m/M where n = number of moles of CaCO₃, m = mass of CaCO₃ and M = molar mass of CaCO₃ = 40 g/mol + 12 g/mol + 3 × 16 g/mol = 52 g/mol + 48 g/mol = 100 g/mol

So, n = m/M

= 50 g/100 g/mol

= 0.5 mol

Since From the chemical equation, 1 mole of CaCO₃ produces 1 mole of CaO, then 0.5 × 1 mole of CaCO₃ produces 0.5 × 1 mole of CaO, which is 0.5 mole of CaCO₃ produces 0.5 mole of CaO.

So, we have 0.5 mol of CaO.

We find the mass of CaO from

n =m'/M' where n = number of moles of CaO = 0.5, m' = mass of CaO and M' = molar mass of CaO = 40 g/mol + 16 g/mol = 56 g/mol

So, m' = nM'

= 0.5 mol × 56 g/mol

= 28 g
