Answer:
The correct answer is B) both are made up of monomers that are linked by covalent bonds
Explanation:
The polymers consist of a set of monomers by covalent bonds. There are those that are natural (DNA formed by nucleotide units, proteins by amino acids, starch by glucose) and synthetics made by human hands (polyethylene formed by ethylene monomers).
Answer:
233 g
Explanation:
Let's consider the following reaction.
CaCO₃ → CaO + CO₂
We can establish the following relations:
- The molar mass of calcium carbonate is 100.09 g/mol.
- The molar ratio of calcium carbonate to carbon dioxide is 1:1.
- The molar mass of carbon dioxide is 44.01 g/mol
The mass of carbon dioxide produced from 530 g of calcium carbonate is:
All I know is that Pseudoscience is: A collection of beliefs or practices mistakenly regarded as being based on scientific method.

There are 67.2 liters of CO2 at STP
<h3>Further explanation</h3>
Given
3 mole of CO2
Required
Volume of CO2 at STP
Solution
Standard conditions for temperature and pressure are used as a reference in certain calculations or conditions
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
So for 3 moles :
= 3 x 22.4 L
= 67.2 L
