If you have 24 g of Mg burn in 32 g Oz, how many g of MgO are produced?

Chemistry

Answer:

Mass = 40 g

Explanation:

Given data:

Mass of Mg = 24 g

Mass of O₂ = 32 g

Moles of MgO = ?

Chemical equation:

2Mg +  O₂ → 2MgO

Number of moles of Mg:

Number of moles of  Mg= Mass /molar mass

Number of moles of Mg= 24g / 24/mol

Number of moles of  Mg= 1 mol

Number of moles of O₂  :

Number of moles of O₂  = Mass /molar mass

Number of moles of O₂  = 32g / 32 g/mol

Number of moles of O₂  = 1 mol

Now we will compare the moles of water with hydrogen and oxygen .

                 Mg            :            MgO

                  2               :               2

                  1                :               1

                 O₂              :                MgO

                  1                :                    2

The number of moles of MgO produced by Mg are less it will be limiting reactant.

Mass of MgO:

Mass = number of moles × molar mass

Mass = 1 mol × 40 g/mol

Mass = 40 g

The pipet used for transferring the pickle juice to the flask was dirty and consequentially some of the pickle juice stuck to th
lesya [120]

Explanation:

Since, some of the given sample is stuck inside and behind the pipet. Hence, there will occur a decrease in the percent of acetic acid.

This is because a decrease in concentration of the acid will also lead to a decrease in the amount of sample taken for the estimation. Since. lesser is the amount or concentration present lesser will be its analyte concentration.

For example, we took 10 mg of a pickel sample but 3 mg of the sample remain stuck in the pipet. This means we actually titrating a  sample less than 10 mg.

Therefore, the analyte concentration in the pickel will also be less.

Shown here is a person shaving.  Under magnification, the shaving foam might look like the image above the shaver. What type of mixture does the foam demonstrate? Give your reasoning.

Foam is a colloid. Colloids includes gas dispersed in a liquid and it also includes gas dispersed in a solid

On the next slide, you can select any answers you want, or you can select nothing. There's no wrong answer.

A student squeezes several oranges to make a glass of orange juice. The juice contains pieces of orange pulp mixed with the juice. Explain why this drink can be considered a combination of a suspension and a solution.

The juice contains sugars, plant pigments, and other chemicals dissolved in water. This is a solution. The pieces of orange pulp will rise to the top or settle to the bottom of the juice if it is allowed to sit. The pieces of pulp mixed with the juice form a suspension

On the right side, you can also select any answers or none at all. There is no wrong answer.

__________________________________________________________

<h2>Explanation:</h2>

There are two main types of mixtures, homogeneous mixtures and heterogeneous mixtures. The components of a homogeneous mixture are evenly distributed throughout the mixture. The properties of a mixture are the same everywhere. The components of a heterogeneous mixture are not evenly distributed. Different regions of this mixture have different   properties.

Particles in a homogeneous mixture do not settle down or separate when left alone. Particles in a heterogeneous mixture eventually separate or settle when left alone.

  • Colloids are a type of heterogeneous mixture that do not naturally settle out quickly, and can be separated with different methods.
  • A suspension is another type of heterogeneous mixtures in which the components of the mixture will quickly settle out or can be filtered or separated.
