Answer:
= a) chirality
Explanation:
Because chiral molecules has four different atoms bonded to the central atom, hence they rotate plane polarized light and produces non-superimposable mirror images
<u>Answer:</u>
<em>The returns of the company as it is given is already large that is 91% and to get an outcome even better is what it is getting now. There should be certain improvements that needs to be applied with the </em><em>help of stoichiometric data gathered.
</em>
<u>Explanation:</u>
Since the cost of materials cannot be affected and have to be bought under similar rate of cost of working or process can be decreased. By using machines calculation and mechanical devices this come would be accurate and the laws would be minimised. Hence the companies outcome would increase.
Answer:
B) high temperatures increase the activation energy of a reaction.
Explanation:
Ammonia is formed when the nitrogen gas is combined with hydrogen gas in a very high temperature. The high temperature increases the activation energy and nitrogen atom make chemical bonds with hydrogen atom results in the production of ammonia. At room temperature, they cannot react with each other.
Silicon is used in producing Pv celss because cells made from the crystallized polycrystalline silicon have efficiencies in the range of 14-18% and a moderate price.
