Answer:

Explanation:

n CaCO3 = mass / m.wt

             = 500  /( 40 + 12 + 16x 3)

           =   5 mole

n CaO = 5 moles  ( from the balanced equation we have 1:1 moles )

mass of CaO = nCaO X m.wt

                       5 x(  40 +16 )

                 =   280 grams

Answer:

0.70 J/g.°C

Explanation:

Step 1: Given data

  • Mass of graphite (m): 402 g
  • Heat absorbed (Q): 1136 J
  • Initial temperature: 26°C
  • Final temperature: 30 °C
  • Specific heat of graphite (c): ?

Step 2: Calculate the specific heat of graphite

We will use the following expression.

Q = c × m × ΔT

c = Q / m × ΔT

c = 1136 J / 402 g × (30°C - 26°C)

c = 0.70 J/g.°C

Which state of matter has the MOST energy?
Ierofanga [76]

The state of matter that has the most energy is gas. In a solid, there is limited room for molecules to move around.

The gas state of matter has the most energy because of how freely the molecules move. Matter is a physical substance of which there are three, and they are solid, liquid, and gas. Solid matter is very compact with the particles very close together and not much movement; therefore, no action, no energy.
