Using the empirical formula, calculate the formula weight of the compound. Use the periodic table to help you.
Type the correct answer in the box. Round your answer to three decimal places.
Answer:
The formula weight of the compound is
46.069 g/mol.
Explanation:
Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:
molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.

1. Find the mass of 0.89 mol of CaCl2.
Answer:
97.9
Explanation:
m= n*M
M CaCl2= 40+ 35.5*2= 110
m= 0.89*110= 97.9
The mass of the given mole of [tex]CaCl_2[/tex] is required.
The mass of the given compound is 98.78 g.
Molar mass of [tex]CaCl_2[/tex]
[tex]M=40.078+35.453\times 2=110.984\ \text{g/mol}[/tex]
n = Number of moles = 0.89 mol
Mass is given by
[tex]m=Mn\\\Rightarrow m=110.984\times 0.89\\\Rightarrow m=98.78\ \text{g}[/tex]
The mass of the given compound is 98.78 g.

Looking at the Periodic Table, how can you determine if an element is a metal, metalloid or nonmetal?
Answer:
It depends on where it's located on the periodic table.
Explanation:
Metals are on left side of the periodic table except Hydrogen (H), which is a nonmetal, then there's the staircase, which has the metalloids, and on the right of the staircase are the nonmetals.

My own doubts came when DDT was introduced for civilian use. In Guyana, within two years it had almost eliminated malaria, but at the same time the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it has greatly added to the population problem.

A medallion was dropped into 20.0 mL of water. The water level rose to 25.3 mL. What is the volume of the medallion? (Vobj = Vf - Vi)
Answer:
5.3 mL
Explanation:
We solve this problem using Archimede's principle, which states that the volume displaced by a submerged object is equal to the volume of the object.
With that in mind we calculate the volume of water displaced by the medallion:
25.3 mL - 20.0 mL = 5.3 mLAs the medallion displaced 5.3 mL of water when submerged, the volume of the medallion is also 5.3 mL.

The correct option for the following reaction is [tex]\gamma[/tex].
In the given reaction we can easily see that the reaction is already complete as a nuclear equation. There is no need for the product to balance the equation as it is not a chemical reaction where reactants and products interact to form new substances.
In this question we can see that a radioactive isotope of iodine-125 ( [tex]^{125}_{53} I[/tex] ) is decaying to produce another isotope of iodine-125 ( [tex]^{125}_{53}I[/tex] ) this process is called beta decay.
As no new element is required to balance the reaction we can say that the answer to this is [tex]\gamma[/tex] as it doesn't add up anything to the reaction.

1. What is the volume
occupied by 20.4 liters of
CO2 at 1200 Torr when it is
at STP
Answer:
Explanation:
From your question you’ll have to assumethat the temperature is constant,since you do not have an initial temperature.
If thats the case thrn you can use;
P1V1=P2V2 to calculate the second volume.
P1=1200 torr
P2=760 torr
V1 = 20.4L
The volume occupied by 20.4 liters of Carbon dioxide (CO₂) at 1200 Torr when it is at Standard temperature pressure is 32.21 L.
How we calculate the volume?Volume of gas can be calculated by arranging the ideal gas equation as:
P₁V₁ = P₂V₂, where
P₁ = given pressure = 1200 Torr
V₁ = given volume = 20.4 L
P₂ = standard pressure = 760 Torr
V₂ = to find?
Here, we consider the moles and temperature of gas is constant, on putting all these value on the above equation we get:
V₂ = (1200 × 20.4) / 760 = 32.21 L
Hence, 32.21 L is the required volume.
