Answer;

-Nucleic acids;

Explanation;

-Living organisms all have DNA (deoxyribonucleic acid) and RNA (ribonuclei acid) which are both nuclei acids. All living organisms store genetic information using the same molecules, these are DNA and RNA.

-DNA and RNA both carry genetic information, however they differ in that RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose, and also RNA has the nucleotide base uracil while DNA contains thymine.

Which one of the following statements is correct? A. A pure substance may be separated by filtration or distillation into two or
torisob [31]

Answer: Option (D) is the correct answer.

Explanation:

  • A pure substance is defined as the substance that is made up of only one type of atom or only one type of molecule.

For example, Cl_{2} is a molecule and it is a pure substance.

Also, substances that contain two or more different element which are chemically combined in a fixed ratio by mass are known as compounds. They are also pure substances.

A pure substance can only be separated by a chemical method and not by any physical method.

  • A heterogeneous mixture is defined as the mixture which contains non-uniform composition of solute particles into the solution.

For example, mud dissolved in water.

It is not necessary that two or more substance present in a heterogeneous mixture should be of same phase.

Also, it is not necessary that combination of a liquid and a solid always results in a heterogeneous mixture.

If the solid is able to dissolve completely into the liquid then it will result in a homogeneous mixture.

  • Whereas a homogeneous mixture is defined as the mixture which contains uniform distribution of solute particles into the solvent.

For example, salt dissolved in water is a homogeneous mixture.

Thus, we can conclude that the statement composition is uniform throughout a homogeneous mixture, is correct.

Methane burns in the presence of oxygen to form carbon dioxide and water.
wlad13 [49]

Answer:

= 9.28 g CO₂

Explanation:

First write a balanced equation:

CH₄ + 2O₂ -> 2H₂O + CO₂

Convert the information to moles

7.50g CH₄ = 0.46875 mol CH₄

13.5g O₂ = 0.421875 mol O₂

Theoretical molar ratio CH₄:O₂ -> 1:2

Actual ratio is  0.46875 : 0.421875 ≈ 1:1

If all CH₄ is used up, there would need to be more O₂

So O₂ is the limiting reactant and we use this in our equation

Use molar ratio to find moles of CO₂

0.421875 mol O₂ * 1 mol CO₂/2 mol O₂=0.2109375 mol CO₂

Then convert to grams

0.2109375 mol CO₂ = 9.28114 g CO₂

round to 3 sig figs

= 9.28 g CO₂
