D is a scintillation counter.
Answer: 169ml
Explanation
At constant temperature, PV is constant
Standard pressure is 101 kpa
150ml X 114kpa=?mlX101 kpa
?=114/101 X150 = 169 ml
CuO+ H2SO4 = CuSO4 + H2O
Redox reaction because both oxidation and reduction is occurring. Cu reducing agent and H2 oxidating
Answer:
water in the flat plate is less so it takes lesser time to disappear
Explanation:
0ne mole of CuSO4.5H2O contains 6.023×10^23 no.of molecules
Again, 1 mole CuSO4.5H2O contains 9 oxygen atoms
Therefore,1 mole CuSO4.5H2O contains 9 × 6.023×10^23 no.of oxygen atoms
Hope this help!
