What questions do you need answers for?
It will not float in the ethyl alcohol because its density is greater than it, so it would sink to the bottom of the solution. However, it will float in the rest of them, it may not float as high in the oil, but it will still be floating.
Answer: The new pressure will be 1.42 atm
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new pressure will be 1.42 atm
Answer:
The correct answer is
B. I and II only
Explanation:
The limitations of robots in factory and research include
1. Robots are capital intensive and require high cost to maintain while still being maintained by humans
2. Robots develop fault and require specific procedures to rectify the fault hance there is high potential for delays in factory production work.
3. When there is a cause for alteration of process or change in operation, the robot most likely will have to be changed as well whike the humans implement the change
4. In research, robots can not recognize unexpected variation indications and synthesis of ideas to explain observed anomalies like humans.
5. A robot does not increase in knowledge of an subject they work on whichose valuable insight is vital to research
Answer is: in chemical reaction with with weak acid, sodium carbonate produce carbonic acid (H₂CO₃), which decomposes into carbon(IV) oxide (fizzy bubbles) and water.
Balanced chemical reaction:
Na₂CO₃ + 2HClO → CO₂(g) + H₂O + 2NaClO.
Chemical decomposition is the separation of a carbonic acid into water and carbon dioxide: H₂CO₃ → CO₂ + H₂O.
