Answer:
Option A
Explanation:
Silicon (Obtained from Sand (SiO2)) is the element that is primarily used in appliances to make electronic chips.
A pure chemical compound is a chemical substance that is composed of a particular set of molecules or ions that are chemically bonded.
Answer:
the moles of mercury are nHg = 65/201
HgO --------> Hg + 1/2O2
65/201 65/201
=> the moles of HgO are 65/201 mol
<span>Saturated hydrocarbon cannot bond with compounds anymore, where as unsaturated hydrocarbons can bond, as they contain double or triple bonds. When they bond, the double and triple bonds break and new separate single bonds are formed with hydrogens or any other external compounds</span>
Also called thermal capacity, is when the amount of heat required to raise the temp. of one mole or one gram of a substance by one degree Celsius without change of phase.
Hope this helps :)
