a. Millimeter
b. Decimeter
c. Meter
d. Kilometer
Answers
Answer: a. Millimeter
Explanation:
A paperclip is a small device or instrument that can be used to hold the papers or stack of papers together. The length of the paperclip can be measured using millimeter. It is equal to the thousands of meters. The millimeter is a dimension which is used to measure the very small length objects which have visible scale distances and length.
Decimeter can be used to measure the length of the object smaller than paperclips. Meter and kilometers are used for objects and distances larger than paperclip.

Is a planar carbon "backbone" possible for cyclopropane? Explain.
Answers
Answer:
Cyclopropane has a planar carbon back bone while propane does not
Explanation:
We have to recognize that in straight chain saturated organic compounds, carbon atoms have a tetrahedral geometry. Each carbon atom is bonded to four other atoms.
However, carbon atoms in cyclic compounds are also sp3 hybridized with each carbon bonded to only four other atoms but the ring system is highly strained.
Cyclopropane is a necessarily planar molecule with a bond angle that is far less than the expected tetrahedral bond angle due to strain in the molecule. Hence, the carbon atoms may have have a "planar backbone".

a. Use the balanced equation C3H8 + 5O2 -> 3CO2 + 4H2O to answer the following questions
i. How many moles of CO2 are produced from 5 moles 02? (1 point)
ii. How many grams of CO2 are produced from 5 moles O2? (2 points)
iii how many grams of CO2 are produced from 128.00g O2? (2 points)
Answers
Answer:
i. 3 moles.
ii. 132.03 grams.
iii. 105.6 grams.
Explanation:
Hello!
In this case, given the balanced chemical reaction, we can proceed as follows:
i. By starting with 5 moles of oxygen, via the 5:3 mole ratio we compute the produced moles of CO2:
[tex]n_{CO_2}=5molO_2*\frac{3molCO_2}{5molO_2} =3molCO_2[/tex]
ii. Now, since we have previously computed the moles of CO2 from the same moles of oxygen, by using its molar mass (44.02 g/mol), we obtain:
[tex]m_{CO_2}=3molCO_2*\frac{44.01gCO_2}{1molCO_2} =132.03gCO_2[/tex]
iii. Now, we need to combine the previously used two proportional factors for the calculation of the mass of CO2 from 128.00 grams of oxygen (molar mass 32.00 g/mol):
[tex]m_{CO_2}=128.00gO_2*\frac{1molO_2}{32.00gCO_2}*\frac{3molCO_2}{5molO_2}*\frac{44.01gCO_2}{1molCO_2}\\\\m_{CO_2}=105.6gCO_2[/tex]

The following is a procedure that was theoretically performed by a student. Read through the procedure and answer the questions below.1.A 10.0 mL graduated cylinder to measure 10.0 mL of a 1.00 M CaCl2 solution into an initially empty 50.0 mL beaker.2.A 50.0 mL graduated cylinder was then used to measure out 25.0 mL of 0.500 M K2CO3. This K2CO3solution was then added to the beaker containing the CaCl2 solution. The solution became cloudy, and the student concluded that a precipitate must have formed. Write a balanced chemical reaction below, including phases, and identify the chemical formula of the precipitate:
Answers
Answer:
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Explanation:
We have the reactants as calcium chloride and potassium carbonate. Recall that we are expecting that the reaction will yield a precipitate. We must keep that in mind as we seek to write its balanced chemical reaction equation.
So we now have;
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Recall that the rule of balancing chemical reaction equation states that the number of atoms of each element on the right side of the reaction equation must be the same as the number of atoms of the same element on the left hand side of the reaction equation.

How much volume (in cm3) is gained by a person who gains 12.3 lb of pure fat?
Answers
Answer:
So we are given with the mass while we are asked for the amount of volume. So this means, we must need an information on the density. From literature, the density of human fat is 0.918 g/cm³. Convert grams to lb by the conversion that 1,000 g = 2.2 lbs.
Density = 0.918 g/cm³ * (2.2 lbs/1,000 g) = 0.0020196 lb/cm³
Volume = Mass/Density = 12.2 lb / 0.0020196 lb/cm³
Volume = 6,040.8 cm³

You have a 500.0 ml graduated cylinder filled with 100.0 mL of water. You carefully add a 178.5 gram piece of iron (density of iron = 7.87 g/mL). What is the final volume reading in the graduated cylinder after adding the iron piece?
Answers
Answer:
122.7 mL
Explanation:
Step 1: Given data
Volume of water: 100.0 mLMass of the piece iron (m): 178.5 gDensity of iron (ρ): 7.87 g/mLStep 2: Calculate the volume of the piece of iron
Density is equal to the mass of the piece divided by its volume.
ρ = m/V
V = m/ρ
V = 178.5 g/(7.87 g/mL) = 22.7 mL
Step 3: Calculate the volume of the mixture
The volume of the mixture is equal to the sum of the volume of water and the iron piece.
100.0 mL + 22.7 mL = 122.7 mL
How many moles of ethane gas, C2H6(g), will occupy 15.0 L at 30 degrees Celsius and 5.0 atm?
Answers
Answer:
3 mol
Explanation:
Given data:
Volume of ethane = 15.0 L
Temperature = 30°C
Pressure = 5.0 atm
Number of moles of ethane = ?
Solution:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
30+273 = 303 K
5.0 atm × 15.0 L = n×0.0821 atm.L/ mol.K × 303 K
75 atm.L = n× 24.87 atm.L/ mol
n = 75 atm.L / 24.87 atm.L/ mol
n = 3 mol
