Answer:

Copper(II) nitrate and silver

Explanation:

2AgNO₃(aq ) + Cu (s) --> Cu(NO₃)₂(aq ) + 2Ag(s)

This can be called a redox reaction because silver nitrate is reduced and copper is oxidized. This can also be called a single replacement reaction because copper replaces silver in the substance silver nitrate.

What is the molar mass of F^2

amm1812

F2 means that there are two flourine's usually a gas is a diatomic molecule.

Since a fluorine molecule has an atomic mass of 18.998 that molar mass of F2 would be 18.9998 *2 = 37.996 except in molar mass the units change so instead of being g/mol it would just be grams.

so 37.996 grams

hope this helps!

Sarah is writing a paper explaining protein formation. Choose the correct way to complete each sentence.

Amanda [17]

Answer :

Amino acids join by forming (1) peptide bonds. Water is released.

The chains of amino acids vary according to their (2) side chains, which each have differing makeup.

These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.

Explanation :

Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine $(-NH_2)$ and carboxylic $(-COOH)$ groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.

Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.

Some examples of amino acids are glycine, lysine, alanine, etc.

Peptide bond formation image is shown below.

In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc

1. If 3.25 moles of oxygen were consumed, how much moles of carbon dioxide are<br> produced?

liraira [26]

Answer:

3.25 mol CO₂

Explanation:

Step 1: Write the balanced equation

C(s) + O₂(g) ⇒ CO₂(g)

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to CO₂ is 1:1.

Step 3: Calculate the number of moles of CO₂ produced from 3.25 moles of O₂

We will use the previously established molar ratio.

3.25 mol O₂ × 1 mol CO₂/ 1 mol O₂ = 3.25 mol CO₂
