Answer:
Mass is 725.46g/cm
Explanation:
Mass = density × volume = 22.6g/cm^3 × 32.1cm^2 = 725.46g/cm
Explanation:
1 grams Gallium to mol = 0.01434 mol
10 grams Gallium to mol = 0.14342 mol
20 grams Gallium to mol = 0.28685 mol
30 grams Gallium to mol = 0.43027 mol
40 grams Gallium to mol = 0.5737 mol
50 grams Gallium to mol = 0.71712 mol
100 grams Gallium to mol = 1.43425 mol
200 grams Gallium to mol = 2.86849 mol
The answer is 58.6934. We assume you are converting between grams Nickel and mole. You can view more details on each measurement unit: molecular weight of Nickel or moles The molecular formula for Nickel is Ni. The SI base unit for amount of substance is the mole. 1 grams Nickel is equal to 0.017037690779543 mole.
Answer:
electrons
Explanation:
When elements combine to form compounds, chemical bonds form between the atoms. Bonds form when atoms share or exchange electrons in a way that gives each atom a complete outer shell.
For example:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and have complete octet.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive. Both have complete octet.
