The density of lead is 11.342 g/cm 3 . What would be the volume of a 200.0 g sample of this metal?
Answer:
The answer is
17.63 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question
mass of lead = 200 g
density = 11.342 g/cm³
It's volume is
[tex]volume = \frac{200}{11.342} \\ = 17.6335743...[/tex]
We have the final answer as
17.63 mLHope this helps you

How is crystallization used in the pharmaceutical industry (simple answer please)
Answer:
CRYSTALLIZATION :IMPORTANT IN THE PHARMACEUTICAL INDUSTRY.IT IS A SEPARATION PROCESS FOR INTERMEDIATE AND A FINAL STEP IN PHARMACEUTICAL INGREDIENTS.A BRAINLIEST PLEEAAAASEA student measures the mass of a substance as 1.7132kg and it's volume as 0.65l. What is the density substance in g/mL? Round your answer to the correct number of significant figures
Answer:
The substance has a density of 2.636 grams per mililiter.
Explanation:
We must remember that density ([tex]\rho[/tex]), measured in grams per mililiters, is the mass of the substance ([tex]m[/tex]), measured in grams, divided by its volume ([tex]V[/tex]), measured in mililiters. That is:
[tex]\rho = \frac{m}{V}[/tex]
In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that [tex]m = 1713.2\,g[/tex] and [tex]V = 650\,mL[/tex], then:
[tex]\rho = \frac{1713.2\,g}{650\,mL}[/tex]
[tex]\rho = 2.636\,\frac{g}{mL}[/tex]
The substance has a density of 2.636 grams per mililiter.

Consider a sealed glass bottle. If the bottle is thrown into a fire, what will happen to the bottle and why? Which law is the best explanation?
Answer:
Charles' Law
Explanation:
If a sealed container of gas were placed in a fire, the temperature and pressure of the gas would increase until the container broke or exploded. ... to volume when temperature is constant.
In the case when the bottle should be thrown into the fire so here Charles' Law should be applied.
What is Charles' Law?Charles's law is a statement where the volume should be occupied by a fixed amount of gas that should be directly proportional to its absolute temperature in the case when the pressure remains constant.
Since in the case when the sealed container of gas should be placed in the fire so here the temperature and the pressure should be increased till the break of the container.

Calculate the mass of oxygen needed to react 10g of calcium to form calcium oxide. 2 Ca + O2→2 CaO
Answer:
Explanation:
1122 g CaO.
I hope I helped you! :)
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.
Given:
The reaction:
[tex]2Ca+O_2\rightarrow CaO[/tex]
Mass of calcium = 10 g
To find:
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide.
Solution:
[tex]2Ca+O_2\rightarrow CaO[/tex]
Mass of calcium = 10 g
Moles of calcium = [tex]\frac{10 g}{40.078 g/mol}=0.25 mol[/tex]
According to reaction, 2 moles of calcium reacts with oxygen, then 0.25 moles of calcium will react with:
[tex]=\frac{1}{2}\times 0.25 mol=0.125 \text{ mol of }O_2[/tex]
Mass of 0.125 moles of oxygen gas:
[tex]0.125 mol\times 31.998 g/mol=3.99975 g\approx 4.0 g[/tex]
The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

Explanation:
Two objects are moving in a straight line. One object has a faster speed than the other. They both have constant speeds (speed is not changing). Is either object accelerating?
Answer:
No
Explanation:
Acceleration refers to the increase in speed over time. Since both of the objects are moving at a constant speed (so the speed is not changing) neither are accelerating, because acceleration requires a positive change in speed.
They may be moving at different speeds, one faster than the other, but neither are changing their own speed so neither are accelerating.

Would convection occur if Earth's mantle were a box 30 km on a side?
Answer:
No.
Explanation:
No, convection does not occur if Earth's mantle were a box 30 km on a side because convection needs medium for the movement of heat energy from one place to another. Convection and conduction are two processes which needs medium for its movement while radiation does not need any medium for its movement. If there is a empty space present between two substances so convection does not occur.

Which phrase best describes an apple?
O homogeneous compound
O heterogeneous substance
O homogeneous mixture
O heterogeneous mixture
Answer:
an apple is best described as a heterogeneous mixture.
The phrase that best describes an apple is heterogenous mixture because it is made up of a different materials.
What is a mixture?A mixture is combination of different components that can be uniform or dispersed and homogenous or heterogenous. A homogenous mixture is the one in which the two or more components are dissolved together to form only one phase.
A heterogenous mixture is composed different phases with uniform or irregular arrangement of materials. Heterogenous mixtures look like a nonseparated random particles which are clearly distinguishable by eyes.
Apple is not a compound but is a mixture made up of different components such as water, pulp, seeds, pigments etc. and each forms their own phases.
Hence, Apple can be termed as a heterogenous mixture.

And experiment a student measures the speed of a toy car locations K through N as it rolls down a ramp based on the data collected in the table exclusion was shown by the student that the unbalanced forces acting on the toy car affect its average speed what reasoning lead to the interpretation of this data and conclusion
Answer:
B) The average speed of the car increases as distance traveled increases.
Explanation:
The unbalanced forces acting on the toy car affect its average speed, The average speed of the car increases as distance traveled increases. Therefore, option A is correct.
What do you mean by an average speed ?The term average speed is defined as the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is corresponded to the magnitude and does not have direction.
Average speed is calculated by dividing the total distance something travels by the total amount of time it spends traveling.
Average speed = Total distance covered / Total Time. The S.I. unit of speed is meter per second.
The unbalanced forces acting on the toy car impact its average speed, The average speed of the car increases as distance traveled increases.
Thus, option A is correct.
