4Ga + 3S2 → 2Ga2S3 1. How many grams of Gallium Sulfide would form if 20.5 moles of Gallium burned?

Answers

Answer:

$m_(Ga_2S_3)=2415.31gGa_2S_3$

Explanation:

Hello,

In this case, for the given chemical reaction, we can notice there is a 4:2 molar ratio between the burned moles of gallium and the yielded moles of gallium sulfide, therefore, we compute them as shown below:

$n_(Ga_2S_3)=20.5molGa*(2molGa_2S_3)/(4molGa)=10.25mol Ga_2S_3$

Then, by using the molar mass of gallium sulfide (235.64 g/mol), we directly compute the grams:

$m_(Ga_2S_3)=10.25mol Ga_2S_3*(235.64gGa_2S_3)/(1molGa_2S_3) \n\nm_(Ga_2S_3)=2415.31gGa_2S_3$

Best regards.

Which of the following statements about compounds is true?A- Each Compound contains only one element.
A- Each Compound contains only one element.

B- Compound can be classified as either heterogenous or homogenous.

C- A Compound has a defined ratio by mass of the elements that it contains

D- Compounds Vary in chemical composition depending on the sample size.

Answers

The following statements about compounds is true that a compound has a defined ratio by mass of the elements that it contains. Option C is correct.

A compound is a substance that is made up of two or more elements that are chemically bonded together. The elements in a compound are always present in a fixed ratio by mass. This means that no matter how much of the compound you have, the ratio of the elements will always be the same.

For example, water is a compound that is made up of hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1 by mass. This means that no matter how much water you have, there will always be twice as much hydrogen as oxygen.

A compound can be classified as either homogeneous or heterogeneous, but not both. Homogeneous compounds have a uniform composition throughout, while heterogeneous compounds have different compositions in different parts of the sample. Compounds do not vary in chemical composition depending on the sample size. The chemical composition of a compound is always the same, regardless of how much of the compound you have. Option C is correct.

Blood samples for research or medical tests sometimes have heparin added. Why is this done?

Answers

It is essential for accurate results that the correct volume of blood is sampled to achieve a correct concentration (and dilution, if liquid heparin is used), and that blood and anticoagulant are well mixed immediately after sampling.
