Answer:
Explanation:
We are given the formula:
This is a molecular formula, because it contains nonmetals.
1. Name the first element
The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix.
2. Second element
The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of <u>hepta</u>-.
- Phosphorous heptachlorine
Add the ending of -ide.
- Phosphorous heptachloride
The prefix used for the second element is hepta. The compound name is phosphorous heptachloride.
Answer:
Temperature
PH
Explanation:
Enzymes are organic catalysts that speeds up the rate of a chemical reaction. Their activities are affected by temperature and pH of the environment among other factors.
- At extreme temperatures, enzymes can easily be denatured and they will cease to act.
- At extremes of pH, they can also be adversely affect.
Enzymes generally have temperature and pH window for their activity.
Answer:
See explanation
Explanation:
The synthesis of asprin involves the;
i) Hydrolysis of Methyl salicylate
ii) Reaction of salicylic acid with acid anhydride
The chemical name of asprin is acetylsalicylic acid.
It is preferable to use an acid anhydride for ester formation with an alcohol rather than a carboxylic acid because we will not produce water which can then cause the hydrolysis of the newly formed ester.
Density = mass/volume
So..
D = 10.74/5
D = 2.148 g/mL ^3
