Answer:

Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase. You can learn more about these stages in the video on mitosis. In cytokinesis, the cytoplasm of the cell is split in two, making two new cells.

A student calculated the mass of a block to be 16.3g. The actual mass of the block is 15.8g. Calculate the student’s percent err

love history [14]

Answer: The student’s percent error is 3.16%.

Explanation:

Calculated mass of the block = 16.3 g

Actual mass of the block = 15.8 g

$\% error=|\frac{\text{Calculated Mass}-\text{Actual Mass}}{\text{Actual Mass}}|\times 100$

$\% error=|\frac{16.3 g-15.8 g}{15.8 g}|\times 100=3.16 \%$

The student’s percent error is 3.16%.

5. A gas occupies 2000. Lat 100.0 K and exerts a pressure of 100.0 kPa. What volume will

Anna [14]

Answer:

4000 L

Explanation:

Step 1:

Data obtained from the question. This include the following:

Initial volume (V1) = 2000 L.

Initial temperature (T1) = 100 K.

Initial pressure (P1) = 100 kPa.

Final temperature (T2) = 400 K.

Final pressure (P2) = 200 kPa.

Final volume (V2) =..?

Step 2:

Determination of the new volume of the gas.

The new volume of the gas can be obtained by using the general gas equation as follow:

P1V1/T1 = P2V2/T2

100 x 2000/100 = 200 x V2/400

Cross multiply to express in linear form.

100 x 200 x V2 = 100 x 2000 x 400

Divide both side by 100 x 200

V2 = (100 x 2000 x 400)/(100 x 200)

V2 = 4000 L

Therefore, the new volume of the gas is 4000 L

An aluminum cup of 140 cm3 capacity is completely filled with glycerin at 20°C. How much glycerin will spill out of the cup if t

mel-nik [20]

Explanation:

The given data is as follows.

coefficient of volume expansion of glycerin ( $\beta$ ) = $5.1 \times 10^{-4} 1/^{o}C$

linear expansion coefficient of aluminum, $(\alpha_{A})$ = $23 \times 10^{-6} 1/^{o}C$

Volume = 100 $cm^{3}$

The increase in volume of the cup will be calculated as follows.

$\Delta V_{c} = V \times 3 \times \alpha \times \Delta T$

= $100 cm^{3} \times 3 \times 23 \times 10^{-6} \times (31 - 20)^{o}C$

= $75900 \times 10^{-6} cm^{3}$

= 0.0759 $cm^{3}$

Formula for increase in volume of glycerine is as follows.

$\Delta V_{g} = V \times \beta_{g} \times \Delta T$

= $100 cm^{3} \times 5.1 \times 10^{-4} 1/^{o}C \times (31 - 20)^{o}C$

= 0.5610 $cm^{3}$

Therefore, volume of glycerin spilled is calculated as follows.

$\Delta V = \Delta V_{g} - \Delta V_{c}$

= (0.5610 - 0.0759) $cm^{3}$

= 0.4851 $cm^{3}$

Thus, we can conclude that 0.4851 $cm^{3}$ glycerin will spill out of the cup.
