In a science lab, a student heats up a chemical from 10 °C to 25 °C which requires thermal energy of 30000 J. If mass of the obj
olganol [36]

Answer:

The specific heat capacity of the object is 50 J/g°C ( option 4 is correct)

Explanation:

Step 1: Data given

Initial temperature = 10.0 °C

Final temperature = 25.0 °C

Energy required = 30000 J

Mass of the object = 40.0 grams

Step 2: Calculate the specific heat capacity of the object

Q = m* c * ΔT

⇒With Q = the heat required = 30000 J

⇒with m = the mass of the object = 40.0 grams

⇒with c = the specific heat capacity of the object = TO BE DETERMINED

⇒with ΔT = The change in temperature = T2 - T2 = 25.0 °C - 10.0°C = 15.0 °C

30000 J = 40.0 g * c * 15.0 °C

c = 30000 J / (40.0 g * 15.0 °C)

c = 50 J/g°C

The specific heat capacity of the object is 50 J/g°C ( option 4 is correct)

1. How many atoms are there in 2.8 moles of carbon? You must show your work to receive credit.
Zolol [24]

Answer:

The answer to your question is

1.-  1.686 x 10²⁴ atoms

2.- 0.25 moles

Explanation:

1.-

              1 mol ---------------- 6.023 x 10²³ atoms

             2.8 moles ----------  x

              x = (2.8 x 6.023 x 10²³) / 1

              x = 1.686 x 10²⁴ atoms

2.-           1 mol ------------------ 6.023 x 10 ²³ molecules

               x moles -------------  1.50 x 10²³ molecules

              x = (1.50 x 10²³ x 1) / 6.023 x 10²³

              x = 0.25 moles
