Answer:

The following data point should be kept when making your calibration.

1.21E-05 M

1.60E-05 M

8.09E-06 M

4.04 E-06 M

Explanation:

From the graph it is obvious that the reading for the concentration 2.02E-06 M does not fall on the straight line. So this point should not be taken to construct the calibration plot.

Find attached of the graph.

How many joules are needed to change the temperate of 22g of water from 18°C to 33°C?
Ira Lisetskai [31]

Answer:

Q =  1379.4 J

Explanation:

Given data:

Mass of water = 22  g

Initial temperature = 18°C

Final temperature = 33°C

Heat absorbed = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Specific heat capacity of water is 4.18 J/g. °C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 33°C - 18 °C

ΔT =  15°C

Q = 522 g ×4.18 J/g.°C× 15°C

Q =  1379.4 J

In a lava lamp, a waxy substance rises and falls repeatedly. What causes the waxy substance to rise? Check all that apply. The w
almond37 [142]

Answer:

The waxy substance is warm.

The waxy substance is less dense than the surrounding liquid.

Convection is occurring.

Explanation:

Convection involves heat transfer by the actual movement of the particles of a substance.

When the wax is heated, the waxy substance becomes warm and rises in the lamp. The warm waxy substance is less dense than the surrounding liquid, this process of rising and falling is as a result of convection occurring in the lava lamp.
