Answer:

Ni ➡️Nickel

Explanation:

The element that is most

likely to be both conductive AND magnetic in nature is "Nickel".

Nickel is a popular magnetic metal and it is known to be ferromagnetic. It's valuable in alloys and used in the production of stainless steel. The element belongs to the transition metals - hard, malleable and ductile. It has high electrical and thermal conductivity.

The element finds usefulness in batteries, phones, kitchen tools, jewellery, etc.

The bomb calorimeter in Exercise 102 is filled with 987g water. The initial temperature of the calorimeter contents is 23.32. A

Sholpan [36]

Answer:

25.907°C

Explanation:

In Exercise 102, heat capacity of bomb calorimeter is 6.660 kJ/°C

The heat of combustion of benzoic acid is equivalent to the total heat energy released to the bomb calorimeter and water in the calorimeter.

Thus:

$-q_{combust} = q_{water} + q_{calori}$

$q_{combust}$ = heat of combustion of benzoic acid

$q_{water}$ = heat energy released to water

$q_{calori}$ = heat energy released to the calorimeter

Therefore,

$-m_{combust}*H_{combust} = [m_{water}*c_{water} + C_{calori}]*(T_{f} - T_{i})$

1.056*26.42 = [0.987*4.18 + 6.66]( $T_{f}$ - 23.32)

27.8995 = [4.12566+6.660]( $T_{f}$ - 23.32)

( $T_{f}$ - 23.32) = 27.8995/10.7857 = 2.587

$T_{f}$ = 23.32 + 2.587 = 25.907°C

Which tools would be necessary to determine whether or not a large regular block will float, without using water?

bulgar [2K]

Scale and measuring tape.
To determine the mass and volume, you can find the density. The block will float if its density is less than that of water.
