Increased temperatures cause changes in atmospheric circulation and increase evaporation and water vapor, resulting in precipitation increases, more intense precipitation, more storms and sea level rise.
Answer:
it means positive and negative charges are equal.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
when a neutral atom loses a electron positive charge is created because number of protons are positive charge becomes greater than negative charge.
X → X⁺ + e⁻
When a neutral atom accept the electron negative charge is created because negative charge is become greater than positive charge.
X + e⁻ → X⁻
We require the information related to atomic mass of the compound and the number of each element present in the compound.
Option A
<u>Explanation:</u>
Molar mass is the amount of any compound present in a given sample. So we can determine the molar mass of any compound by the ratio of atomic mass of the compound to the amount of compound or element present in the sample.
So it can be defined as the mass of the compound in a given sample with respect to the number of elements present in that sample. Thus, we require the information related to atomic mass of the compound and the number of each element present in the compound.
