A solid rubber ball with a mass of 5.9 grams sank in water. A hollow rubber ball with the same mass floats in water. Explain why this might be. Please answer ASAP!
Answers
Answer:
The hollow ball is more buoyant than the solid ball.
Explanation:
The hollow ball will float while the solid ball sinks because the volume of water displaced by the hollow ball is more than that displaced by the solid ball.
An object floats when it displaces a volume of water equal to its weight. A solid ball is more compact, and hence, does not displace a lot of water when dropped into a bowl full of water. On the other hand, the hollow ball will have a larger curved surface area, since it has no fill. This will make it displace a larger volume of water and hence make it float.
if a student reacts 4.40 ml of acetic acid with 3.35 ml of isopentyl alcohol and obtains 3.25 ml of isopentyl acetate as the product, what was the percent yield
Answers
The percent yield of isopentyl acetate is 71.23% when reacting 4.4 ml f acetic acid with 3.35 ml of isopentyl alcohol
Percentage yield calculationPercentage yield can be defined as the ratio of the actual yield of a reaction to the theoretical yield of a reaction, multiplied by 100.
The percentage yield is calculated as follows:
Percentage yield = (actual yield/theoretical yield) × 100Given data:
Volume of acetic acid used = 4.40 ml
Volume of isopentyl alcohol used = 3.35 ml
Volume of isopentyl acetate obtained = 3.25 ml
Density of acetic acid = 1.049 g/mL and its molar mass = 60.05 g/mol
Density of isopentyl alcohol = 0.809 g/mL and its molar mass = 88.15 g/mol
Density of isopentyl acetate = 0.876 g/mL and its molar mass = 130.19 g/mol
The balanced chemical equation for the reaction is:
C5H11OH + CH3COOH → CH3COOC5H11 + H2O
First, we need to determine which reactant is the limiting reactant. We can do this by calculating the number of moles of each reactant:
Number of moles of acetic acid = (volume in mL) x (density) / (molar mass)Number of moles of acetic acid = (4.40 mL) x (1.049 g/mL) / (60.05 g/mol) = 0.0767 molNumber of moles of isopentyl alcohol = (volume in mL) x (density) / (molar mass)Number of moles of isopentyl alcohol = (3.35 mL) x (0.809 g/mL) / (88.15 g/mol) = 0.0307 molThe mole ratio of acetic acid to isopentyl alcohol in the reaction is 1:1, so the limiting reactant is isopentyl alcohol because there are fewer moles of it.
The theoretical yield of isopentyl acetate can be calculated from the number of moles of limiting reactant:
Number of moles of isopentyl acetate = (number of moles of limiting reactant) = 0.0307 molNow we can calculate the percent yield:
Percent yield = (actual yield / theoretical yield) x 100%The actual yield is given as 3.25 mL of isopentyl acetate, but we need to convert this to moles:
Number of moles of isopentyl acetate = (volume in mL) x (density) / (molar mass)Number of moles of isopentyl acetate = (3.25 mL) x (0.876 g/mL) / (130.19 g/mol) = 0.022 molPercent yield = (0.022 mol / 0.0307 mol) x 100% = 71.23%Therefore, the percent yield of isopentyl acetate is 71.23%.

At a high concentration do you have more or less particles per unit volume
Answers
Answer:
More particles per unit volume
Explanation:
Concentration means the amount of solute in a solution. Now, the amount of solute also means the number of particles of solute present in a solution.
Hence, when we use the term "high concentration", we imply that the amount of solute present or the number of particles present in a solution is high.
Thus, at high concentration, there are more solute particles than solvent particles in a solution.

30 miles per hour
80 miles per hour
50 miles per hour
60 miles per hour
Answers
Michelle drove 50 miles per hour
Explanation:
300 miles divided by 6 hours equals 50 miles per hour.
Miles per hour basically just means
\(\frac{Total number of miles}{total number of hours}\)
You can infer from the use of the word 'per' that you should divide the number of miles by the number of hours to get an average speed.
Similarly, to work out the number of miles driven you could say you travelled 50 miles per hour for 6 hours, so you would multiply 50mph x 6 hours to work the equation in reverse.

during a laboratory experiment, 44.18 grams of al2o3 was formed when o2 reacted with aluminum metal at 290.0 k and 1.3 atm. what was the volume of o2 used during the experiment? 3o2 4al → 2al2o3 (5 points)
Answers
During a laboratory experiment, 44.18 grams of al2o3 was formed when o2 reacted with aluminum metal at 290.0 k and 1.3 atm , the volume of O2 used during the experiment 3o2 4al → 2al2o3 is approximately 12.58 liters.
To find the volume of O2 used during the experiment, we can use the ideal gas law equation PV = nRT,
where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
First, we need to calculate the number of moles of Al2O3 formed. The molar mass of Al2O3 is 101.96 g/mol. Therefore, 44.18 grams of Al2O3 is equal to 44.18 g / 101.96 g/mol = 0.433 moles of Al2O3.
According to the balanced chemical equation, 3 moles of O2 react with 4 moles of Al to form 2 moles of Al2O3. Therefore, the number of moles of O2 used can be calculated as follows:
(0.433 moles of Al2O3) * (3 moles of O2 / 2 moles of Al2O3) = 0.6495 moles of O2.
Next, we can use the ideal gas law equation to find the volume of O2. The temperature is given as 290.0 K and the pressure is given as 1.3 atm.
(1.3 atm) * (V) = (0.6495 moles of O2) * (0.0821 L*atm/mol*K) * (290.0 K)
Solving for V, we get:
V = (0.6495 moles of O2) * (0.0821 L*atm/mol*K) * (290.0 K) / (1.3 atm)
V ≈ 12.58 liters

To calculate the amount of alum required for a 45 mg/d (million gallons per day) water treatment plant, we need to convert the units from ppm (parts per million) to lbs (pounds).
Given that the optimum dosage for coagulation is 25 ppm of Al₃+:Convert ppm to lbs per million gallons:
25 ppm Al₃+ x 1 lb Al₂(SO₄)₃ / 1000 ppm Al₃+ = 0.025 lbs Al₂(SO₄)₃ per million gallons
Calculate the total amount of alum required for the entire treatment plant:0.025 lbs Al₂(SO₄)₃ per million gallons x 45,000,000 gallons per day = 1,125 lbs Al₂(SO₄)₃ per day
Therefore, a 45 mg/d water treatment plant would require approximately 1,125 lbs of alum per day at an optimum dosage of 25 ppm Al₃+.

Answers
Option (b) is correct. The molarity of the resulting solution is 0.652 M. This is calculated using the expression of ideal gas equation and molarity.
12.7 l of argon at 33°c and 735 torr are dissolved in enough water to give a final volume of 0.750l. so,
P = 735.0 torr
= (735.0/760) atm.
= 0.9671 atm.
V = 12.7 L
T = 33.0 o C
= (33.0+273) K
= 306 K
We can find the number of moles using ideal gas equation. The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions. The ideal gas equation is,
P * V = n*R*T
0.9671 atm. * 12.7 L = n * 0.08206 atm. L/mole . K * 306 K
n = 0.4891 mole
Now, we will calculate Molarity. Molarity or molar concentration is the number of moles of solute per liter of solution, which can be calculated using the following equation,
Molarity = number of mole / final volume
= 0.4891 mole / 0.750 L
