the density of mercury is 13.6 g/cm3. what approximate mass of mercury is required to fill a 4.0 ounce bottle? an ounce is approximately 30 cm3. group of answer choices 53 g 1632 g 2 g 540 g
The approximate mass of mercury required to fill a 4.0 ounce bottle is 1632 g .
An ounce is approximately 30 cm3, so the calculation is as follows: 13.6 g/cm3 x 30 cm3 = 408 g. Since there are 28.35 g in an ounce, 408 g / 28.35 g = 14.4 ounces.
Therefore, 14.4 ounces x 1632 g/ounce = 1632 g.The reason why mercury is so dense is because it is a heavy metal composed of molecules that are closely packed together. This makes it very heavy for its volume, and it is one of the densest elements found in nature. It also has a high boiling point, making it ideal for use in thermometers and other temperature measuring instruments.

How many kilograms are there in 2.0 x 10-15 grams? In dimensional analysis
Answer:
2.0 x 10^-21 kilograms
Explanation:
Dimensional analysis is a technique for converting between different measuring units. The procedure is identifying the measurement units involved, figuring out the conversion factor between them, and then utilising the conversion factor to compute the desired outcome.
We need to translate 2.0 x 10-15 grams to kilograms in this instance. One kilograms is equivalent to 106 grams. In order to find the kilograms. We can divide the amount of grams by 106:
2.0 x 10-15 grams per 106 is 2.0 x 10-15 kilograms per 106 grams, or 2.0 x 10-21 kilograms.
Consequently, 2.0 x 10-15 grams are equal to 2.0 x 10-21 kilos.
. Afternoon rainstorms are common in the rainforest but not in the desert. What is one factor that make deserts less likely to have an afternoon rainstorm? O Low humidity O Low wind and speeds High air pressure O High temperatures
Answer:
Humidity—water vapor in the air—is near zero in most deserts. Light rains often evaporate in the dry air, never reaching the ground. When the air sinks it creates an area of high pressure. These high-pressure areas experience very dry and warm conditions resulting in a hot desert climate (eg the Sahara and Kalahari deserts). Winds blow from areas of high to low pressure, which transfers the air from where it is sinking to where it is rising.
Temperatures exhibit daily extremes because the atmosphere contains little humidity to block the Sun's rays.

How do you determine the freezing point of a solution from its cooling curve?
Drawing two straight lines connecting the data points above and below the freezing point allows one to infer the solution's freezing point from the graph.
The freezing point of the solution is the temperature that corresponds to the point where the two lines converge.
Pure liquid cooling curves are different from solution cooling curves. Since a pure liquid freezes at a constant temperature, a flat, horizontal zone is anticipated on the cooling curve. If the cooling is kept up until all of the liquid has solidified, the temperature will eventually drop to the bath's temperature as the solid cools. On the other hand, for a solution, the temperature drops at a slower pace when freezing takes place. This happens because the solvent is freezing out completely, increasing the concentration of the liquid solution.

8. When 50.0 g of MgCO3 react completely with H3PO4, as shown below, 15.8 g of CO₂ is produced.
Determine the theoretical and percent yield for this reaction?
2 H3PO4 + 3 MgCO3 → Mg3(PO4)2 + 3 CO2 + 3 H₂O
The theoretical yield for this reaction is 78.61 g of CO2 and the percent yield is 20.0%, when 50.0 g of MgCO3 react completely with H3PO4.
What is theoretical yield?The theoretical yield is the maximum amount of product that can be produced from a chemical reaction, calculated using the stoichiometry of the reaction equation. It is based on the assumption that the reaction proceeds perfectly, without any loss or waste of reactants, and without any interference from side reactions.
The theoretical yield is calculated by determining the number of moles of each reactant, using the balanced chemical equation to calculate the number of moles of product that can be produced, and then converting this to the corresponding mass of product. It is a useful reference for determining the efficiency of a reaction and for evaluating the quality of the results obtained in a laboratory experiment.
Calculation of Theoretical yield
To calculate the theoretical yield, determine the number of moles of MgCO3 and use the balanced chemical equation to calculate the number of moles of CO2 produced.
The number of moles of MgCO3 is given by:
n(MgCO3) = m(MgCO3) / M(MgCO3)
n(MgCO3) = 50.0 g / 84.31 g/mol
n(MgCO3) = 0.595 mol
Using the balanced chemical equation, calculate the number of moles of CO2 produced:
n(CO2) = 3 * n(MgCO3)
n(CO2) = 3 * 0.595 mol
n(CO2) = 1.785 mol
The mass of CO2 produced can then be calculated:
m(CO2) = n(CO2) * M(CO2)
m(CO2) = 1.785 mol * 44.01 g/mol
m(CO2) = 78.61 g
This is the theoretical yield for the reaction.
The percent yield is a measure of the efficiency of the reaction, and is calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100:
% yield = (actual yield / theoretical yield) * 100
% yield = (15.8 g / 78.61 g) * 100
% yield = 20.0%

Jade's basketball team is choosing a color for their new uniforms. They have a catalog from a vendor with 17 choices. Jade's teammates have already ruled out 9 of the colors. They choose 1 of the remaining colors at random. Assuming that is one of the available colors, what is the probability that the color blue will be chosen?
The probability that the color blue will be chosen is 2/8 or 1/4, since there are 8 colors remaining after 9 have been ruled out and 2 of those are blue.
Because 9 colors have been eliminated, there are now 17 - 9 = 8 colors remaining. Because two of the eight hues are blue, the chance of selecting blue is 2/8, which simplifies to 1/4.
Another way to look at it is that there are 17 different colors to pick from, and two of them are blue, so the likelihood of selecting blue if all colors were available is 2/17. But, because 9 colors have been ruled out, the probability must be recalculated using the new total of 8, yielding a probability of 1/4.
