Cr2O3+ 2Al -----------> 2Cr+ Al2O3
Cr2O3--------2Cr.
( oxidation no. of cr +3 to +1 means hain of electron so it act as oxidizing agent)
similarly,
2Al------> Al2O3
( oxidation no. of Al +1 to +3 means loss of electron so it act as reducing agent)
Answer:
Molarity of a solution = 1 mol / L
Explanation:
Given:
Amount of NaOH =20 g
Amount of water = 0.50 l
Find:
Molarity of a solution
Computation:
1 mol of NaOH = 40 g
So,
Moles of NaOH = 20 / 40 g = 0.50 mol NaOH
Molarity of a solution = moles of solute / Liters of solution
Molarity of a solution = 0.50 / 0.50
Molarity of a solution = 1 mol / L
<span>Sucrose </span>is an example of a polymer separate but equal means that both races get the same thing they just dont get it at the same time.<span />
Each particular chemical reaction cannot be expected to occur at identical rates.
True. Not all chemical reactions happen at the same rate, depending on the catalyst.
the mass of 1 mole of phosphorus atoms is approximately 30
g
hope this helps :)
