Upon combustion, a compound containing only carbon and hydrogen produces 3.54 g CO2 and 1.09 g H2O. Find the empirical formula of the compound.

Answers

The empirical formula of the compound is CH₃

What is the empirical formula of the compound?

The empirical formula is determined as follows:

Given the general equation of the combustion of hydrocarbons as follows:

CxHy + O₂ → x CO₂ + y H₂O

mass of CO₂ produced = 3.54 g

molar mass of CO₂ = 44 g/mol

moles of C in the sample = 3.54/44  = 0.08 moles

molar mass of C = 12 g/mol

mass of C in the sample =  0.08  * 12 = 0.96 g

mass of H₂O produced  = 1.09 g

molar mass of water = 18 g/mol

moles of H in the sample = 1.09 /18  * 2

moles of H in the sample = 0.12 moles

Ratio of C : H = 0.08 : 0.12

Ratio of C : H = 1 : 3

Therefore, the empirical formula of compound = CH₃

Answers

It has been observed that most US adult intake high levels of sodium and low level of potassium.

The American Health Association (AHA) published in its reports that US adults consume food containing more sodium and avoid food containing potassium. It causes various side effects and health-related problems. It was estimated that 99.4% of the total United States adults intake high levels of sodium on daily a basis. AHA guidelines recommend (<1500 mg) of sodium to be consumed. They consume even more than the Institute of Medicine's tolerable upper Intake level which is 2300 mg.

In the US, adults aged over 51 years or people suffering from diabetes, chronic kidney disease, or hypertension are recommended by the Dietary Guidelines to reduce sodium intake to 1500 mg per day. The overall result suggested that 98.8% consumed more than 1500 mg per day, and 60.4% consumed more than 3000 mg per day. These calculations of intake are more than double the recommendation guidelines. Only less than 2% of US adults and around 5% of US men consumed less than 4700 mg per day of potassium.

Therefore, it is concluded that the maximum US adult intake is high levels of sodium and low level of potassium.

First convert the temperature into kelvin.

25.00°C+273.15=298.15K

Now convert the hear capacity into J/g.K

28.0(j/mol.K)×1mol/200.59g

=0.1396J/g.K

Now calculate the hear transferred using the specific heat of mercury

q=mcΔT

q=(29.5g)0.1396J/gK)(234. 32 -298.15 K)

q=-262.85 j = -0.26286 Kj

The calculation would involve the enthalpy of fusion, but with a negative sign.

(29.5g Hg)(1mol/200.59g Hg)×-2.29Kj/mol= -0.064221 Kj

Add the heat transferrers of both process together

Answers

Starting with solid argon at room temperature, we need to cool it to -189.2 c to convert it into the liquid state.

Then, we need to heat it slightly till it reaches a temperature of -185.7 c. At this temperature, the liquid argon will convert into gaseous argon.

There are three states of matter i.e, solid state, liquid state, and gaseous state. These states are interconvertible which means that we can convert a substance from one state to another.

The conversion from solid to liquid and then gas or vice versa happens at specific temperatures that are known as boiling point, melting point, freezing point, etc.

The melting point is the temperature at which a solid gets converted into a liquid.

The boiling point is the temperature at which a liquid gets converted into a gas.

The melting and boiling points of Argon are -189.2 °C and -185.7 °C respectively.

Thus, starting with solid argon at room temperature, we need to cool it to   -189.2 °C to convert it into the liquid state.

Then, we need to heat it slightly till it reaches a temperature of -185.7 °C. At this temperature, the liquid argon will convert into gaseous argon.
