An empirical formula means that the chemical formula of a compound has to be in it's simplest whole number form. In this case, D is not an empirical formula because it is able to be simplified to C3H6. All the other answers are simplified to the simplest whole number ratio. Think of it as a fraction being in simplest form.

Ionic compound K₂O is potassium superoxide. CaCl₂ is calcium chloride. The compound Mg₃N₂ is magnesium nitride and NaClO is sodium hypochlorite and KNO₃ is potassium nitrate.

Ionic compounds are formed between metals and non-metals. They are bonded by lose of electrons from the metal to the non-metals. An ionic compound is named starting with the cation and then the anionic part is named second with the suffix "ide" , "ate" , "ite" etc.

The compounds with the general formula M₂O are called super oxides. K₂O is called potassium superoxide or dipotassium oxide.

The compound, CaCl₂ is named as calcium chloride. The subscripts in formula  are the number of each atoms in the compounds.

Similarly Mg₃N₂ is named as magnesium nitride and KNO₃ is called potassium nitrate. The compound NaClO is named as sodium hypochlorite.

Explanation:

According to the concept of percent yield, the percent yield of carbon dioxide is 72.51%.

Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.

In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .

In the given example, theoretical yield of carbon dioxide is as 32 g oxygen produces 44 g carbon dioxide,thus 32.5 g which is obtained by 2.5 moles of oxygen will require 32.5×44/32=44.68 g

Thus , on substitution in formula of percent yield, 32.4/44.68×100=72.51%.

Hence, the percent yield of carbon dioxide is 72.51%.

Answer:

A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.

Explanation:

nun

Answer:

Both the pebble and metal bead of the same mass will be equally accelerated  if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.

56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

A body's mass is an inherent quality. Prior to the discovery of a atom or particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the very same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to acceleration in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

2 Al + 3 Cl[tex]_2[/tex] → 2 Al C l[tex]_3[/tex]

mole of Al =  135.0/ 26=5.19mol

mole of Cl[tex]_2[/tex] = 75.0/ 35 =2.14 mol

mass of aluminum chloride =  56.8g

Limiting reagent = Al

excess reactant =  Cl[tex]_2[/tex]

Therefore, 56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

Answer:

4.03 g

Explanation:

The mass in grams of the hydrogen gas is 4.0 g

From the question,

We are to determine the mass in grams of the hydrogen gas.

First, we will determine the number of moles of hydrogen gas present.

Using the formula,

[tex]Number\ of\ moles =\frac{Number\ of \ molecules}{Avogadro's\ constant}[/tex]

From the given information,

Number of hydrogen molecules = 1.204 × 10²⁴ molecules

Thus,

Number of moles of hydrogen gas present = [tex]\frac{1.204 \times 10^{24} }{6.02 \times 10^{23} }[/tex]

Number of moles of hydrogen gas present = 2 moles

Now, for the mass of the hydrogen gas

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of hydrogen gas = 2.016 g/mol

Then,

Mass of the hydrogen gas = 2 × 2.016

Mass of the hydrogen gas = 4.032 g

Mass of the hydrogen gas ≅ 4.0 g

Hence, the mass in grams of the hydrogen gas is 4.0 g
