Answer:
Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... The rest of the bonds all contain electrons from both hydrogen and nitrogen, so they would be considered ordinary covalent bonds.

Answer:
10kg = 10 x 1000 = 10,000g
Explanation:
To know the quantity with the largest mass, we have to express all the units in grams:
for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g
0.001kg = 0.001 x 1000 = 1g
1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g
2 x 10²cg = 2 x 10² x 10⁻² = 2g
10kg = 10 x 1000 = 10,000g
Note:
10⁻ ¹ deci(d)
10⁻² centi(c)
10⁻³ milli(m)
10⁻⁹ nano(n)
10³ kilo(k)
