Volume of Water -

Chemistry
1 answer:
miss Akunina [59]3 years ago
5 0

Answer:

3.8 g/mL

Explanation:

From the question given above, the following data were obtained:

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Mass of object = 51.3 g

Density of object =?

Next, we shall determine the volume of the object. This can be obtained as follow:

Volume of Water = 60 mL

Volume of Water + Object = 73.5 mL

Volume of object =?

Volume of object = (Volume of Water + Object) – (Volume of Water)

Volume of object = 73.5 – 60

Volume of object = 13.5 mL

Finally, we shall determine the density of the object as illustrated below:

Volume of object = 13.5 mL

Mass of object = 51.3 g

Density of object =?

Density = mass /volume

Density of object = 51.3 /13.5

Density of object = 3.8 g/mL

Thus, the density of the object is 3.8 g/mL

In an electrolytic cell, the magnitude of the standard cell potential is the:______
melamori03 [73]

Answer:

a. minimum voltage that must be supplied for a redox reaction to occur

c. always equal to Eanode - Ecathode

Explanation:

In an electrolytic cell;  The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e \mathbf{E^{\theta}_{cell}=E_{anode} - E_{cathode}} )

As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.

Therefore, option a and c are both correct.

uranmaximum [27]

Answer:

When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

how much energy would it take to heat a section of the copper tubing that weights about 660.0 gram, from 12.93 degree Celsius to
expeople1 [14]

Answer:

                      Q  =  2647 J

Explanation:

                    Specific heat capacity is the amount of energy required by one Kg of a substance to raise its temperature by 1 °C.

In thermodynamics the equation used is as follow,

                                                 Q  =  m Cp ΔT

Where;

           Q  =  Heat  =  ?

           m  =  mass  =  660 g

           Cp  =  Specific Heat Capacity  =  0.3850 J.g⁻¹.°C⁻¹

           ΔT  =  Change in Temperature  =  23.35 °C - 12.93 °C  =  10.42 °C

Putting values in eq. 1,

                            Q  =  660 g × 0.3850 J.g⁻¹.°C⁻¹ ×  10.42 °C

                            Q  =  2647 J
