Answer:
A
Explanation:
Metal atoms are held together by metallic bonds. The metallic bonds are composed of a lattice of positive ions in a 'sea of electrons'.
The metal atoms are held together by strong electrostatic attraction between the positive ions and the 'sea of electrons' leading to high melting point of metals including copper.
Similarly, when a metal undergoes stress, the layers of the metal roll over each other but the lattice remains in place. Hence for metals such as Copper, layers of atoms in the lattice can slide over each other thereby making the metal malleable.
Metals oxidize by electron loss. Since Copper is metal, it can also be oxidized to form copper ions by loosing electrons.
The most stable conformation of
trans-1-tert-butyl-2-methylcyclohexane is the one in which both the
tert-butyl group and the methyl group are located near the equatorial position.
Trans conformation are usually stable at the equatorial position to avoid the
bulkyl group ( the tert-butyl group and methyl group) be together to reduce the
so called Steric hindrance.
DescriptionIn chemistry an element is a species of atom having the same number of protons in its atomic nuclei. For example, the atomic number of oxygen is 8, so the element oxygen describes all atoms which have 8 protons. In total, 118 elements have been identified.
density is the mass of an object/ liquid per unit volume
formula for density is as follows
density = mass / volume
the mass of steel is 80 g
and density is 8 g/cm³
substituting the values in the equation we can find the volume
volume = 80 g/cm³ / 8 g
volume = 10 cm³
volume of the sample is 10 cm³
Answer:
There are 
moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells
Explanation:
Given that:
The number of molecules present in one bacterial cell is 
molecules
and the sample contains 
molecules.
Number of moles = number of molecules /Avogadro's number
where;
Avogadro's number = 6.023 × 10²³
Number of moles = 
Number of moles = 
moles
So; moles is present in one bacteria cell
Similarly; the sample contains molecules.
Therefore; the number of moles present in the bactoX is = 
= moles
