Answer: 1,013.32 cal × 4.18 J/cal = 4,235.68 J
Explanation:
1) Data:
Water ⇒ C = 1 cal/g°C
m = 65.8 g
Ti = 31.5°C
Tf = 36.9°C
Heat, Q = ?
2) Formula:
Q = mCΔT
3) Calculations:
Q = 65.8g × 1 cal/g°C × (46.9°C - 31.5°C) = 1,013.2 cal
4) You can convert from calories to Joules using the conversion factor:
1 cal = 4.18 J
⇒ 1,013.32 cal × 4.18 J/cal = 4,235.68 J
Answer:
two examples are blood and soapy water.
Explanation:
Answer: 6 atoms in total
Explanation:
It has one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms.
Answer:
C. Mole
Explanation:
Chemical formula deals with mole number
Option B is a balanced equation and follows the Law of Conservation of Mass. This is because the number of atoms of each element on both sides are the same.
