Answer:
119.5 J
Explanation:
First we <u>calculate the temperature difference</u>:
- ΔT = 100 °C - 50 °C = 50 °C
Then we can <u>calculate the heat released</u> by using the following formula:
Where q is the heat, Cp is the specific heat, ΔT is the temperature difference and m is the mass.
We <u>input the data</u>:
- q = 0.239 J/g°C * 50 °C * 10.0 g
Answer:
C E F G
Explanation:
1s2 2s2 2p2 is carbon element, group 4 so A is false, it is not a noble gas so B is false, P-block elements are from 13 to 18 so carbon is included so C is true, S-block elements are columns 1 and 2 and Helium so carbon not included so D false, it is in period 2 so E true, has 2 energy levels so F true, it is a representative element so G is true
The answer is; the average annual precipitation on Earth equals the amount of water that evaporates
This water cycle is also known as the hydrological cycle. At any one moment in the cycle, there is water lost from the biosphere to the atmosphere through evapotranspiration. The water in the atmosphere also precipitates back to earth surface as rain or snow and the cycle continues.
