3- Fully folded proteins typically have polar side chains on their surfaces, where electrostatic attractions and hydrogen bonds
Elden [556K]

Answer:

Option C= A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

Explanation:

All three given options a, b and d have common mechanism to accommodate the polar amino acid.

A= A hydrogen bond forms between two polar side chains.

B= A hydrogen bond from between a polar side chain and protein back bone.

D =  hydrogen bond form between polar side chains and a buried water molecules.

All these are use to accommodate the polar amino acid.

While option C is not used. which is:

A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

Aluminum reacts with chlorine gas to produce aluminum chloride according to the following equation. Al + Cl2 → AlCl3 Which of th
anzhelika [568]
<h3><u>Answer</u>;</h3>

B. 3/2

<h3><u>  Explanation;</u></h3>

Balance the chemical equation

2Al + 3Cl2 → 2AlCl3

We want to convert moles of AlCl3 to moles of Cl2

The conversion factor is 2 mol AlCl3/3 mol Cl2.

We choose the one that makes the units cancel:

x mol AlCl3 x (3 mol Cl3)/(2mol AlCl3) = x mol Al

The fraction for the molar ratio is 3/2.

Determine the mass of SO₂ that contains 6.075 × 10^26 S atoms.​
Misha Larkins [42]

Avogadro's law states that in a mole of any substance, there are 6.022 \times 10^{23} atoms. This means that in the given sample, there are

\frac{6.075 \times 10^{26}}{6.022 \times 10^{23}}=1008.8010627 \text{ mol}

  • The atomic mass of sulfur is 32.06 amu.
  • The atomic mass of oxygen is 15.9994 amu.

So, the atomic mass of sulfur dioxide is

32.06+2(15.9994=64.0588 \text{ g/mol}

Therefore, the mass is:

(64.0588)(1008.8010627)=\boxed{64620 \text{ g (to 4 sf)}}
