Explanation:
It's asking for the temperature of the warm water when the probe was moved in, rather than the temperature it measured. In this case I'd probably choose 33 degrees Celsius.
Answer: 351 joules
Explanation:
1 calories contain 4.184joules
Therefore 83.9calories would contain: 83.9 x 4.184 = 351 joules.
1.6 mol x 42.39g/1 mol = 67.82g of LiCl.
Answer:
A) 9.60 g
B) 19.2 g
C) 28.8 g
Explanation:
A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g
0.600 mol x 16.00 g/mol=9.60 g
B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g
0.600 mol x 32.00 g/mol=19.2 g
C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g
0.600 mol x 48.00 g/mol=28.8 g
Each period represents once a principal energy level has been reached for an element.
