Temperature of gas: ___ C
Height of the column of gas: ___ cm
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, height of Column of gas is 7.4cm and temperature of Gas is 82°C or 355 K.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Height of Column of gas is 7.4cm and temperature of Gas is 82°Cor 355 K.
Therefore, height of Column of gas is 7.4cm and temperature of Gas is 82°C or 355 K.

Answer: The average atomic mass of nitrogen is 14.0066 amu
Explanation:
Mass of isotope N-14 = 14.00307 amu
% abundance of isotope N-14= 99.64% = [tex]\frac{99.64}{100}[/tex]
Mass of isotope N-13 = 15.0001 amu
% abundance of isotope N-13= (0.36)% = [tex]\frac{0.36}{100}[/tex]
Formula used for average atomic mass of an element :
[tex]\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})[/tex]
[tex]A=\sum[(14.00307)\times \frac{99.64}{100})+(15.0001)\times \frac{0.36}{100}]][/tex]
[tex]A=14.0066amu[/tex]
Therefore, the average atomic mass of nitrogen is 14.0066 amu

what is the molecular formula for a compound with the empirical formula: K2SO4 and a molecular mass of 696g
Answer:
K8S4O16 or K8(SO4)4 depending on if the SO4 is supposed to represent sulfate or not
Explanation:
Find the molar mass of K2SO4 first:
2K + S + 4O ≈ 174 g/mol
Divide the goal molar mass of 696 by the molar mass of the empirical formula:
696 / 174 = 4
This means you need to multiply everything in the empirical formula by 4:
K2SO4 --> K8S4O16 or K8(SO4)4 depending on if the SO4 is for sulfate or not
K₈S₄O₁₆ is the molecular formula for a compound with the empirical formula K₂SO₄ and a molecular mass of 696 g.
What is empirical formula?Empirical formula of a compound is defined as the simplest whole number ratio of atoms which are present in a compound.It does not make any mention of the arrangement of atoms or the number of atoms. The empirical formula gives information about the ratio of number of atoms which are present in a compound.
Molecular formula is determined from the empirical formula by dividing the molar mass of a compound by the empirical formula mass. The resultant which should be a whole number or very close to the whole number , then the subscripts are multiplied by the whole number to get the molecular formula.
In this case molar mass of K₂SO₄ that is 696 is divided by empirical formula mass which is 174.25 g which gives 4 , subscripts of K₂SO₄ is multiplied by 4 to give K₈S₄O₁₆ .
Thus, the molecular formula of compound is K₈S₄O₁₆.

What is the air pressure on top of the mountain?
Explanation:
At sea level, the atmospheric pressure would be a little over 100 kPa (one atmosphere or 760 mm Hg). If we climb to the top of Mount Everest (the highest mountain in the world at 29,029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).

5.36 liters of nitrogen gas are at STP. What would be the new volume if we increased the moles from 3.5 moles to 6.0 moles?
Answer:
[tex]V_2=9.20L[/tex]
Explanation:
Hello there!
In this case, according to the given STP (standard pressure and temperature), it is possible for us to realize that the equation to use here is the Avogadro's law as a directly proportional relationship between moles and volume:
[tex]\frac{V_2}{n_2}= \frac{V_1}{n_1}[/tex]
In such a way, given the initial volume and both initial and final moles, we can easily compute the final volume as shown below:
[tex]V_2= \frac{V_1n_2}{n_1} \\\\V_2=\frac{5.36L*6.0mol}{3.5mol}\\\\V_2=9.20L[/tex]

A coffee cup calorimeter will not be used to
directly measure the enthalpy of magnesium
combustion because
✓ the coffee cups could melt.
The calorimeter is made of coffee cups instead of
a beaker because coffee cups are
✓ better insulators
than beakers.
You will not measure the enthalpy of the reaction
of
✓ H2 and 02
in the coffee cup calorimeter because this reaction involves gases
Instead, you will use a well-known published
value.
These are the correct answers on edge 2021
Answer:
Ingles porfavor
Explanation:
The calorimeter is used to measure the heat of the system. The enthalpy of the combustion of magnesium cannot be measured by the calorimeter as it could melt the cup.
What is a coffee cup calorimeter?A coffee cup calorimeter is a styrofoam cup that contains partially filled water and is dipped with a thermometer. The reaction occurs in the water of the cup and hence differs from the bomb calorimeter.
The enthalpy of combustion is rigorous which can dissolve the polystyrene cup and hence is not used. They are better insulators than a beaker. The coffee cup calorimeter is not used to measure the enthalpy of hydrogen and oxygen as they involve gases that can escape the cup.
