<span>What are some examples of monomers and oligomers?
</span>Organic molecules, such as proteins, carbohydrates, lipids and nucleic acids, are made of simple subunits called monomers. <span>Plasticizers are </span>oligomeric esters widely used to soften thermoplastics such as PVC and <span>urethane acrylate </span>.

</span><span>If a chemical compound accelerates and regulates metabolic reactions, which type of role does it play - structural or physiological?
</span>I believe the function that it plays would be physiological since it focuses more on the regulation of the reactions inside the body.
Answer:
2.9 grams.
Explanation:
- From the balanced reaction:
<em>Mg + 1/2O₂ → MgO,</em>
1.0 mole of Mg reacts with 0.5 mole of oxygen to produce 1.0 mole of MgO.
- We need to calculate the no. of moles of (1.8 g) of Mg and (6.0 g) of oxygen:
no. of moles of Mg = mass/molar mass = (1.8 g)/(24.3 g/mol) = 0.074 mol.
no. of moles of O₂ = mass/molar mass = (6.0 g)/(16.0 g/mol) = 0.375 mol.
<em>So. 0.074 mol of Mg reacts completely with (0.074/2 = 0.037 mol) of O₂ which be in excess.</em>
<em></em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of Mg produce → 1.0 mol of MgO.
∴ 0.074 mol of Mg produce → 0.074 mol of MgO.
<em>∴ The amount of MgO produced = no. of moles x molar mass </em>= (0.074 mol)(40.3 g/mol) = <em>2.98 g.</em>

Gloves is the tool component which will unlikely present a hazard in this scenario.
<h3>
What is Hazard?</h3>
This is referred to as potential source of harm when performing various types of activities.
Gloves will unlikely cause harm as it is used to prevent the risk of electric shock when handling electrical devices which is why it is the most appropriate choice.
