Answer:
1.) The nitric acid solution will oxidize and thus dissolve _*(Zn and Pb)*_. This will allow to identify _**Pt**_.
2) To distinguish between _*(Zn and Pb)*_, we can use the nickel nitrate.
3) The nickel nitrate solution will oxidize and thus dissolve _**Zn**_ and will not oxidize or dissolve _**Pb**_.
Explanation:
1) Unlike Zinc and Lead, Platinum does not react with Nitric acid. So, it will be the only metal from step 1 that doesn't react. Pt is identified in this manner.
2) Nickel is higher than Lead in the activity series, but Zinc is higher than both of them in the activity series. This selectivity can be used to distinguish between Zinc and Lead metal powders.
3) Because Zinc is higher than Nickel in the activity series, it means that Zinc metal can and will displace Nickel from Nickel Nitrate solution. Therefore the Nickel Nitrate solution will oxidize and dissolve the Zinc metal.
But, there will be no reaction with the Lead metal powders sample as Pb is lower than Ni in the activity series, so, Nickel Nitrate solution will not oxidize or dissolve the Lead metal powders.
Answer:
no, Charon is significantly smaller than Mercury
Answer:
Correct option is
A
Explanation:
The number of molecules of CO involves in the slowest step will be 0 because CO is not involve in the slowest step i.e. rate determing step.
<h2> Interconversion of energy.</h2>
Explanation:
- Carbon moves from plants and animals to soils in the form of cycle.
- When we take in oxygen we release carbon dioxide gas
into the atmosphere. - Animals and plants give carbon dioxide gas through the process called respiration and transpiration.
- From fossil fuels carbon moves in the atmosphere.
- The fuels like wood or coal when burned releases carbon dioxide into the atmosphere.
- The Matter is conserved in the carbon cycle as carbon absorbs energy and then it releases the same amount of energy.
- Carbon changes from one form to another, but the total amount of carbon remains the same.
