Answer:
my gues is red not a 100% but its in the 700s
Explanation:
Although we are all unique, there are often obvious similarities within families. Maybe you have the same nose as your brother or red hair like your mother? Family similarities occur because we inherit traits from our parents (in the form of the genes that contribute to the traits).
This passing of genes from one generation to the next is called heredity. Simple organisms pass on genes by duplicating their genetic information and then splitting to form an identical organism. More complex organisms, including humans, produce specialised sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. The process that produces gametes is called meiosis.
The product of this reaction could be N2.
Among the options, only atoms of nitrogen have five electrons on their outermost shell.
The fact that they have five electrons in their outermost shells implies that they can combine by sharing six electrons in a triple bond.
When this occurs, each of the nitrogen atoms involved in the bond now has an octet of electrons. Hence, the product formed when the atoms share six electrons. Which molecule could be the product of the reaction is N2.

Answer:
16.93%.
Explanation:
- If we have 1.0 mol of Fe₃Al₂(SiO₄)₃:
∴ The mass of 1.0 mol of Fe₃Al₂(SiO₄)₃ = (no. of moles of Fe₃Al₂(SiO₄)₃)(the molecular mass of Fe₃Al₂(SiO₄)₃)
∴ The mass of 1.0 mol of Fe₃Al₂(SiO₄)₃ = (1)(the molecular mass of Fe₃Al₂(SiO₄)₃) = (the molecular mass of Fe₃Al₂(SiO₄)₃).
∴ The mass of 1.0 mol of Fe₃Al₂(SiO₄)₃ = 3(atomic weight of Fe) + 2(atomic weight of Al) + 3(molecular weight of (SiO₄)₃) = 497.7474 g.
The mass of Si in 1.0 mole of Fe₃Al₂(SiO₄)₃ = 3(atomic mass of Si) = 3(28.0855 g/mol) = 84.2565 g.
∵ The mass % of Si = (the mass of Si)/(the mass of Fe₃Al₂(SiO₄)₃) = (84.2565 g)/(497.7474 g) = 16.93%.
Answer:
342.3 g
Explanation:
From the question given above, the following data were obtained:
C = 12.011 g/mol
H = 1.00794 g/mol
O = 15.9994 g/mol
Molar mass of C₁₂H₂₂O₁₁ =?
C = 12 × 12.011 = 144.132 g
H = 22 × 1.00794 = 22.17468 g
O = 11 × 15.9994 = 175.9934 g
Total mass = 144.132 + 22.17468 + 175.9934
Total mass = 342.3 g
