One of the key differences is that of the waysin which electrons are utilized. Metals form ionic solids, as well as metallic solids. This has todo with the hold that metals have on their electrons. This hold is quite weak, ranging from no desire to hold them, as observed in the large number of ionic solids, to a low affinity as observed in metallic solids, such as copper wire, tin sheets, and iron bars. Nonmetals have a desire for electrons, ranging from quite strong, as observed in ionic solids, to moderately weak, as observed in countless molecular and covalent solids, such as sucrose, napthalene, and diamond. This difference in types of solids revolves around the electron conduction among the atoms/ions of the solids. This conduction is highest in metallic substances and lowest in nonmetallic substances.
Answer:
C
Explanation:
because valence electrons are located at the last energy level
Answer:
Water volume produced is 7.3 mL
Explanation:
This the reaction:
4NH₃ (g) + 5O₂ (g) → 4NO (g) + 6H₂O (g)
We have to work with density, to solve this question
Density of ammonia = Ammonia mass / Ammonia volume
0,00073 g/mL = Ammonia mass / 6300 mL
(Notice, we had to convert 6.3L to mL)
0.00073 g/mL . 6300 mL = Ammonia mass → 4.599 g
Mass / Molar mass = Mol
4.599 g / 17g/m = 0.270 mole
Ratio is 4:6
4 mole of ammonia produce 6 mole of water
0.270 mole produce (0.270 .6)/4 = 0.405 mol
Molar mass . mole = mass
18 g/m . 0.405 m = 7.30 g
Water density = 1 g/mL
Water density = Water mass / Water Volume
1g/mL = 7.30 g / Water volume
Water volume = 7.3 mL
CO will diffuse faster than CO2 because its molar mass is smaller.
The rate of diffusion depends on molecular weight and the least mass will diffuse faster.
