Answer: Covalent type of bonding does a material most likely have if it has a low melting point, does not dissolve in water and has a dull appearance.
Explanation:
A covalent bond is a bond formed by sharing of electrons between the combing atoms. The bond through with these atoms are combined is called covalent bonding.
Some characteristics of non-metals are as follows.
Covalent compounds have low melting point.
Being non-polar in nature covalent compounds do not dissolve in water.
They are brittle in nature.
Thus, covalent type of bonding does a material most likely have if it has a low melting point, does not dissolve in water and has a dull appearance.
The answer is 17.2365 Kilograms
Mass divided by Volume
-----
Density
32.7 g Zn
Explanation:
First convert the amount of gas into moles:
11.2 L H2 × (1 mol H2/22.4 L H2) = 0.500 mol H2
Then use the molar ratio to find the amount of zinc necessary to produce the amount of gas above:
0.500 mol H2 × (1 mol Zn/1 mol H2)
= 0.500 mol Zn
Now use the molar mass of zinc to find the number of grams of zinc for the reaction to occur:
0.500 mol Zn × (65.38 g Zn/1 mol Zn)
= 32.7 g Zn
