C. A magnet causing a metal object to move
Answer:
The volume on the tank is 6, 20 L
Explanation:
We use the formula PV=nRT. We convert the units of pressure in kPa into atm and temperature in Celsius into Kelvin:
0°C=273K
101,325kPa---1 atm
275kPa --------x=(275kPax 1 atm)/101,325kPa= 2,71 atm
PV=nRT --> V=nRT/P
V= 0,750 mol x 0,082 l atm /K mol x 273 K/ 2, 71 atm= <em>6, 20 L</em>
Answer: The rabbit population reached carrying capacity during the fourth year of the 10 years we set. Introduction: Population densityis the number of individuals in a population per unit of area. Some limiting factors only affect a population when its density reaches a certain level.
Explanation:
Minerals are inorganic and coal is made of decomposed plants, which are organic
Elemental zinc displaces the copper
Explanation:
In this reaction the zinc added to the copper sulfate solution has displaced the copper in the compound.
This is a single displacement reaction.
Zn + CuSO₄ → ZnSO₄ + Cu
This is the reaction of the recycling process.
The reaction is driving by the positions of the elements in the reactivity series of metal.
- In a single displacement reaction, an atom higher up in the activity series displaces another that is lower.
- Zinc is higher that copper in the activity series and it reacts with the sulfate.
- It will then push the copper out as the solid product in the solution.
- Elements higher up in the series are more reactive
