The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:
(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.
(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.
In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
Answer:
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series. Magnesium oxide decomposes into magnesium and oxygen. If 4.03 g of magnesium oxide decomposes to form 2.43 g of magnesium, what mass of oxygen gas is also released in the reaction
The word say magnesium oxide decomposes to magnesium and oxygen
the chemical symbols say
MgO-----------> Mg + O2 (since natural oxygen is diatomic)
the balanced equation says
2MgO-------------->2Mg + O2
4.03 gm----------> 2.43 + ?0 gms
tour high school Algebra I class says
? = 4.03 -2.43 =1.60
your chemical analytcal lab says %mO in MgO = 16/40.3 = 39.7%
your calculator says
39.7/100 X 4.03 = 1.60
all of these prove the law of conservation of mass
Explanation:
rate of diffusion of H2S is about one Fourth times faster than that of SO2 by what factors is the rate of diffusion of ammonia faster than that
Answer:
Explanation:
1 mole of Fe require 2 Moles of NiO(OH)
so for 4.25 mol of Fe and 6.70 mol of NiO(OH), Fe is the limiting reagent.
1 mole produces 1 mole of Fe(OH)2
4.25 moles will produce 4.25 moles of Fe(OH)2
Answer:
Explanation:
density = m/v
answer = 2.0819 g/ml
rounded (correct sig figs) = 2.08
