In balanced equation there are same number of atoms in each element on both sides of the equation. unbalanced equation is when there are different number of atoms in each element on the both sides
In a combustion reaction, one of the reactants is always oxygen.
Answer:
Number of Protons = 19
Number of Neutrons = 25
Number of Electrons = 19
Explanation:
Number of Protons:
The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Potassium is 19 therefore, it contains 19 protons.
Number Neutrons:
The number of neutrons present in atom are calculated as,
# of Neutrons = Atomic Mass - # of protons
As given,
Atomic Mass = 43
# of Protons = 19
So,
# of Neutrons = 43 - 19
# of Neutrons = 24
Number of Electrons:
As we know for a neutral atom the number of electrons are exactly equal to the number of protons present in its nucleus. So, for 19 protons in neutral Potassium atom there must be 19 electrons.
Answer:
May 17
Explanation:
When it refers to 0% light it describe a new moon, from a new moon to a full Moon are 14 days, then if you start a full moon on May 3 and you add 14 days it means that the next new Moon would be on May 17.
Answer:
Soils are a function of the five soil-forming factors: climate, organisms, relief, parent material, and time. Each of these factors range on a continuum, so the different soils of the world number in the thousands. Soil scientists recognize 12 major orders of soils.
