In a very violent reaction called a thermite reaction, aluminum metal reacts with iron (III) oxide to form iron metal and aluminum oxide according to the following equation:

Answers

Answer 1

Answer: Here's the equation:
Fe2 O3 + 2Al → 2Fe + Al2 O3

Here's the question.
What mass of Al will react with 150g of Fe2 O3?

In every 2 moles Al you need 1 mole Fe2O3

moles = mass / molar mass
moles Fe2O3 = 150 g / 159.69 g/mol
= 0.9393 moles

moles Al needed = 2 x moles Fe2O3
= 2 x 0.9393 mol
= 1.879 moles Al needed

mass = molar mass x moles
mass Al = 26.98 g/mol x 1.879 mol
= 50.69 g
= 51 g (2 sig figs)

So the mass of Al that will react with 150g of Fe2 O3 is 51 grams.

Carbon can share a maximum of how many of its valence electrons when bonding to other atoms?2

Cannot be determined

Answers

Carbon can share a maximum of four of its valence electrons when bonding to other atoms. This is the reason why organic molecules can be so large because of this bonding. Suppose you have a compound of CCl4. You know that chlorine can only share 1 electron because 7 of its electrons are filled. Also, in carbon, it can only share 4 electrons because 4 of it are already filled. That is why carbon needs four chlorine to form CCl4.

Answers

The observed trait of the individual rabbitis referred to as the phenotype.

Organisms receive a set of genes from their parents. This set of genes that an organism receives from its parents is called the genotype of the organism.

However, genes occur in pairs called alleles. In a pair of alleles, one gene is dominant while other is recessive. The dominant gene determines the expressed traits of the individual organism.

This expressed trait of the individual organism as determined by the dominant gene is called the phenotype of the organism.

Which organic reaction produces rubber and plastics? A) polymerization B) esterification C) saponification D) fermentation

Answers

Answer: Option (A) is the correct answer.

Explanation:

When monomers in a chemical reaction combine together then it results in the formation of long chains. This process is known as polymerization.

For example, rubber and plastic are formed by polymerization.

Esterification is defined as a process in which esters are formed when an acid is heated with alcohol.

Saponification is defined as a process in which aqueous alkali is heated with a fat or oil resulting in the formation of a soap.

Fermentation is a process in which bacteria like microorganisms, yeast etc help in the breakdown of a substance into simpler substances.

Thus, we can conclude that polymerization is an organic reaction which produces rubber and plastics.

The answer would be, A) Polymerization.
