Given are the steps in the titration process:

- Clean and rinse the burette with water
- Read and record the initial burette volume.
- Fill the burette with standardized base solution
- Rinse the burette with standardized base solution

The steps in the titration process is as follows:

1.) Clean and rinse the burette with water
2.) Rinse the burette with standardized base solution
3.) Fill the burette with standardized base solution
4.) Read and record the initial burette volume

Write the chemical equation for the reaction whose enthalpy change is the standard enthalpy of formation of fructose, C6H12O6(s)
ziro4ka [17]

Answer:

6 C(s) + 6_{H2}(g) + 3_{O2}(g)

Explanation:

The chemical equation of the reaction is as follows

According to the question, data provided in the question is shown below:

C_6H_12O_6

The C = Carbon and its standard state is Graphite C(s)

The H = Hydrogen and its standard state is H_2 (s)

The O = Oxygen and its standard state is O_2 (s)

Now the chemical equation for the reaction is

6 C(s) + 6_{H2}(g) + 3_{O2}(g)

How much silver can be produced from 125g of Ag2S
rosijanka [135]

Answer:

108.9g of Silver can be produced from 125g of Ag2S

Explanation:

The compound Ag2S shows that two atoms of Silver Ag, combined with an atom of Sulphur S to form Ag2S. We can as well say the combination ration of Silver to Sulphur is 2:1

•Now we need to calculate the molecular weight of this compound by summing up the molar masses of each element in the compound.

•Molar mass of Silver Ag= 107.9g/mol

•Molar mass of Sulphur S= 32g/mol

•Molecular weight of Ag2S= (2×107.9g/mol) + 32g/mol

•Molecular weight of Ag2S= 215.8g/mol + 32g/mol= 247.8g/mol

•From our calculations, we know that 215.8g/mol of Ag is present in 247.8g/mol of Ag2S

If 247.8g Ag2S produced 215.8g Ag

125g Ag2S will produce xg Ag

cross multiplying we have

xg= 215.8g × 125g / 247.8g

xg= 26975g/247.8

xg= 108.85g

Therefore, 108.9g of Silver can be produced from 125g of Ag2S

When explaining chemical reactions to a friend, Brianna models a reaction by taking several colors of modeling clay and making a
Ludmilka [50]

Answer:

True

Explanation:

A synthesis reaction is one that involves the combination of more than one reactants to form a single product. This is directly opposite to a decomposition reaction where a complex compound is broken down into various products.

Examples of synthesis reaction are;

1. The combination of sodium with chlorine to form sodium chloride.

2. The combination of hydrogen and oxygen to form water

so explaining what Brianna did, the models of clay are the reactants coming together to form a single product which is the sculpture.
