Answer:
44.01
Explanation:
12.01 + 16.00 + 16.00 = 44.01
The diet soda will float, but the regular soda will sink, I think. I had the same problem and that was my answer.
The question is incomplete, the complete question is;
The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube, as shown in the diagram below. The volume is measured to be 45.6mL . The atmospheric pressure in the lab is measured as 765 torr , and the equilibrium vapor pressure of water at 298 K is 24 torr .(i) The pressure inside the tube due to the H2(g)
Answer:
741 torr
Explanation:
From the question we can see that the atmospheric pressure in the lab is 765 torr.
The vapour pressure of water = 24 torr
From Dalton's law of partial pressure, we know that;
Total pressure = Pressure of the H2 + Partial pressure of water vapour
Therefore;
Pressure of H2 = Total pressure - Partial pressure of water vapour
Pressure of H2 = 765 torr - 24 torr = 741 torr
Answer: (B) proton And neutrons
Explanation:
First of all we should know that, 1 Joule = 0.000239 kilocalories.
So, 6.6×
J = 6.6× × 0.000239 kilocalories
6.6× J = 15774000 kilocalories
= 1.58 × 
kilocalories
One joule is described as the quantity of electricity exerted when a pressure of 1 newton is implemented over a displacement of 1 meter. Within the SI machine, the unit of labor or electricity is the Joule.
The kilocalorie, or meals calorie, is the quantity of warmth required to elevate one kilogram of water 1 °C. warmness capability is the amount of heat required to raise one gram of material 1 °C beneath steady pressure. A kilocalorie is the amount of warmth required to raise the temperature of 1 kilogram of water one diploma Celsius.
