Answer:
electrons can bond atoms together
Explanation:
when two atoms share electrons,they are locked together by that sharing.These are called covalent bonds...but when an atom gives one of its electrons to another atom ,they are held together by electric forces.HOPE THAT HELPED☺
Answer:
Five peaks
Explanation:
GaAs would show two peaks:
Ga-69 + As-75 = 144
Ga-71 + As-75 = 146
Their intensities are in the ratio 60 : 40 = 100:67.
Ga₂S₂ would show three peaks:
Ga-69 + Ga-69 + 2As-75 = (Ga-69)₂(As-75)₂ = 288
Ga-69 + Ga-71 + 2As-75 = (Ga-69)(Ga-71(As-75)₂ = 290
Ga-71 + Ga-71 + 2As-75 = (Ga-71)₂(As-75)₂ = 292
Their relative intensities are in the ratio
(60 + 40)² = 60² : 2×60×40 : 40² = 3600 : 4800 : 1600 = 75 : 100 : 33
A spectrum of a mixture of GaAs and Ga₂As₂ would show five peaks:
Two at m/e 144 and 146 with intensity ratios 100: 67 and
Three at m/e 288, 290, and 292 with intensity ratios 75:100 :33.
We cannot predict the absolute sizes of the peaks because we do not know the relative amounts of GaAs and GaAs₂.
Yes it is just in the back which still makes it negative

Answer:</h3>
55.81%
<h3>
Explanation:</h3>
Mass percentage composition of an element in a compound can be calculated by dividing the mass of the element in the compound by the relative formula mass of the compound and expressing it as a percentage.
Therefore;
% composition = (Mass of the element/ relative formula mass)100%
In this case;
We are given the mass of the element (oxygen) and the mass of the compound (Kaolinite) thus;
Mass % of oxygen in kaolinite = (Mass of oxygen/ mass of Kaolinite)100%
% composition of Oxygen = (8.009 g/14.35 g)100%
= 55.81 %
Therefore; the mass percent of oxygen in Kaolinite is 55.81%
