The ​density of lead is 11.342 g/cm​ 3​ .​ What would be the volume of a ​200.0 g sample of this metal?

Answers

Answer:

The answer is

17.63 mL

Explanation:

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 mL

Hope this helps you

The liquid state of matter can be described as

Answers

Answer:

The liquid state of matter is an intermediate phase between solid and gas. ... Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility

Explanation:

A liquid is a nearly incompressible fluid with a nearly constant volume regardless of pressure that adapts to the shape of its container. It belongs to one of the four basic states of matter.

Volume retention and conformity to the shape of a liquid's container are two of its most noticeable physical characteristics. When a liquid substance is poured into a container, it conforms to the shape of the container and will stay inside the container so long as the liquid state persists.

The intermolecular forces of attraction in a liquid state of matter are stronger than those in a gaseous state but weaker than those in a solid state.

Calculate the mass of oxygen needed to react 10g of calcium to form calcium oxide. 2 Ca + O2→2 CaO

Answers

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.

A 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

Answers

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.

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

Answers

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.

Would convection occur if Earth's mantle were a box 30 km on a side?​

Answers

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.
