<u>Answer:</u>

<u>Answer:hydrocarbons</u>

Explanation:

The simplest organic compounds are the hydrocarbons, which contain only carbon and hydrogen. Alkanes contain only carbon–hydrogen and carbon–carbon single bonds, alkenes contain at least one carbon–carbon double bond, and alkynes contain one or more carbon–carbon triple bonds.

1.29 g piece of lead has a temperature of 26.0 °C. If it loses 1.90 J of heat to its surroundings, what is its new temperature.
malfutka [58]

The new temperature of the piece of lead will be 37.5°C

SPECIFIC HEAT CAPACITY:

  • The amount of heat absorbed or released by a substance can be calculated by using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or released (J)

m = mass of substance (g)

c = specific heat capacity

∆T = change in temperature (°C)

According to this question,

Q = 1.90J

m = 1.29g

T1 = 26°C

T2 = ?

c = 0.128 J/g°C

1.90 = 1.29 × 0.128 × (T2- 26°C)

1.90 = 0.165 (T2 - 26°C)

1.90 = 0.165T2 - 4.29

1.90 + 4.29 = 0.165T2

6.19 = 0.165T2

T2 = 37.5°C

Therefore, the new temperature of the piece of lead will be 37.5°C.
