Sedimentary rocks. Not sure though
Answer:
four electrons
Explanation:
Let us attempt to write the electronic configuration of carbon in the ground state. This electronic configuration will now be;
C- 1s2 2s2 2p2
The outermost principal energy level of carbon is the n=2 level which houses the 2s2 and 2p2, making a total of four electrons in the outermost principal energy level of an atom of carbon in the ground state.

<h3>What is nitrogen balance?</h3>
The term nitrogen balance refers to the fact that there is a balance between the intake and the loss of nitrogen. The intake of nitrogen occurs when a person takes in food that contain proteins which are a rich source of nitrogen in the body and helps in the process of the build up of the cells in the body.

<span>Heat released by the water: mass * specific heat * ΔT
Heat released by the water = 55.9 g * 1 cal / (°C g) * (99.2 - 96.9 )°C
Heat absorbed by the zinc metal = mass * specifi heat * ΔT
Heat absorbed by the zinc metal = 23.9 g * Cp * (96.9 - 21.1) °C
Heat absorbed by zinc metal = heat released by water
=> 23.9 * Cp * 75.8 = 55.9 * 1 * 2.3
=> Cp = 128.57 / 1811.62 = 0.0071 cal / (g°C)
Answer: 0.0071 cal / (g°C)
