Highest percentage of gold by weight can be determined by looking at the atomic mass of the other elements in the compound. the smaller the total of mass of the other elements, the heigher the percentage of Au will be in that compound
a. AuOH, OH- = 17 gram/mole
b. Au(OH)3, 3 x OH- = 3 x 17 = 51 gram/mole
c. AuCl3 = 3x35.5= 106.5 gram/mole
d. AuI3 = 3x127 = 381 gram/mole
as we can see AuOH has the least Molecular mass, hence % of Au will be the highest compared to other choices
Answer: A
Answer:
Co2,so2
Explanation:
Hybridization is the mixing of atomic orbitals to form new hybrid orbitals.
Molecule shapes arise from how many hybrid orbitals the central atom uses and how they are arranged.

The acceleration : 0.25 m/s²
<h3>Further explanation</h3>
Given
mass = m = 24 kg
Force = F = 6 N
Required
The acceleration
Solution
Newtons' second law :
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
ΣF = m x a

Input the value :
6 N = 24 kg x a
a = 6 : 24
a = 0.25 m/s²
Answer: 1 proton, 0 electron and 1 neutron are present in 1 H⁺ isotope.
