Answer:
4.85 x 10^25
Explanation:
thats what i was told by a calculator
Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)
1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)
2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules
3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes
4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically
5. it can be separated but it needs energy physically cannot be separated.
Explanation:
Answer:
B. mass, volume
Explanation:
Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.
The balanced molecular equation , with Na⁺ as the spectator ion .
2NaCrO₂(aq) + 2H₂O(l) + 6NaClO(aq) →2CrO₄(aq) + 3Cl₂(g) + 4NaOH(aq)
There are following steps involve in balanced redox reaction in basic medium .
- Divide the reaction into two half reactions .
- Balance the elements other than oxygen and hydrogen .
- Balance the oxygen atom by adding .
- Balance the hydrogen atom by adding .
- Add on bath side .
- Combine and to form form .
- Balance the charge by adding .
- Add the half reaction and simply .
The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .
