Answer:
The correct answer is
C. 6 Protons
Explanation:
Carbon is a nonmetallic element that is available in both organic and inorganic compounds.
Carbon belongs to group 14 elements in the periodic table,carbon is a chemical element with the symbol C and atomic number 6, it can form long chains with its own atoms, a feature called catenation.
Two allotropes of carbon available are diamonds and graphites, which have different crystalline structures
The physical properties of carbon vary widely with the allotropic form.
examples are.
- Graphite, diamonds and coal are all nearly pure forms of carbon
- Diamond is highly transparent. Graphite is opaque and black
- Diamond is one of the hardest substances known to man. Graphite is soft and often used as the "lead" in lead pencils
- Diamond has a very low electrical conductivity. Graphite is a very good conductor
- Very brittle, and cannot be rolled into wires or pounded into sheets
Vanadium (V)
Vanadium is the only one in the 4th period here so
Carbon atom has 4 valence electron and can form 4 bonds with carbon and other atoms and it can also form single, double and triple bond with other carbon atoms.
So, the statement is false.
Answer:
156 g of AlCl₃ will be produced from 3.5 moles of HCl.
Explanation:
Given data:
Number of moles of HCl = 3.5 mol
Grams of AlCl₃ produced = ?
Solution:
Balanced Chemical equation:
3HCl + Al(OH)₃ → AlCl₃ + 3H₂O
Now we will compare the moles of AlCl₃ with HCl from balanced chemical equation.
HCl : AlCl₃
3 : 1
3.5 : 1/3×3.5 = 1.17 mol
Mass of AlCl₃ produced:
Mass = number of moles ×molar mass
Mass = 1.17 mol × 133.341 g/mol
Mass = 156 g
Thus 156 g of AlCl₃ will be produced from 3.5 moles of HCl.
