You can use physical properties to compare substance by the texture depending on how rough, hard, soft etc
Synthetic materials are made from natural resources and can be used for many purposes.
<h3>What is synthetic material ?</h3>
Synthetic materials are made by chemically changing the starting substances to create a material with different characteristics. Some examples of synthetic materials are plastics, medicines, and new fuels.
A synthetic substance may be chemically identical to a naturally-occurring substance or may be different.
Item is made from a synthetic material :
- Plastic bag
- Plastic bottle
- Disposable diaper
- Synthetic fiber/cloth (polyester, nylon, or rayon)
- Kevlar
- Artificial sweetener
- Synthetic fuel (Synfuel)
- Synthetic rubber
- Chloroquine (Malaria drug)
- Taxol(Cancer drug)
- Physostigmine (Glaucoma drug)
- Aspirin

Answer:
0.2598 M
Explanation:
Molarity is mol/L, so we have to convert the grams to moles and the mL to L. To convert between grams and moles you need the molar mass of the compound, which is 36.46g/mol.
Round to the lowest number of significant figures = 0.2598 M
Cao + H2O ---->Ca(OH)2
Calculate the number of each reactant and the moles of the product
that is
moles = mass/molar mass
The moles of CaO= 56.08g/ 56.08g/mol(molar mass of Cao)= 1mole
the moles of water= 36.04 g/18 g/mol= 2.002moles
The moles of Ca (OH)2=74.10g/74.093g/mol= 1mole
The mass of differences of reactant and product can be therefore
explained as
1 mole of Cao reacted completely with 1 mole H2O to produce 1 mole of Ca(OH)2. The mass of water was in excess while that of CaO was limited
Answer:
Following two compounds have Hydrogen Bond Interactions;
1) CH₃(CH₂)₂NH₂ (Propan-1-amine)<span>
2) </span>CH₃(CH₂)₂NH(CH₂)₄CH₃ (N-propylpentan-1-amine)
Explanation:
Hydrogen Bond Interactions are formed between those molecules which has hydrogen atoms covalently bonded to most electronegative atoms like Fluorine, Oxygen and Nitrogen. This direct attachment of Hydrogen to electronegative atom makes it partial positive resulting in hydrogen bonding with neighbor's partial negative most electronegative atom. So, in above selected compounds it can be seen that both compounds contain hydrogen atoms directly attached to Nitrogen atoms, Therefore, allowing them to form Hydrogen Bonding Interactions.
