Answer: Clay
Explanation:
Putty is a cementing material which is used for white wash and filling up the holes on the wall. It is a mixture of calcium carbonate along with oil solvent. The dough is a powdery substance. When putty and dough are combined they form a clay which is of high density as compared to other two materials. It is thick and rigid.
So, when a putty and dough combines then a clay will form.
Sodium hydroxide and hydrochloric acid can react with each other to form sodium chloride in the reaction HCl(aq)+NaOH(aq)→H₂O(l)+NaCl(aq).
I hope this helps. Let me know if anything is unclear.
There are two isotopes of uranium abundant in nature
U235 and U238
As given that the sample has average molar mass of 237.482 amu
Let the amount of U235 in 100g sample = x
the amount of U238 in 100 g sample = 100-x
the average molar mass = [235(x) + 238 (100-x)] / 100
237.482 = [235(x) + 238 (100-x)] / 100
237.482 X 100 = [235(x) + 238 (100-x)]
23748.2 = 235 x + 23800 - 238x
51.8 = 3x
x = 17.27 g
So percentage of U-235 = 17.27 %
It's 1s2 2s2 2p6 3s2 3p3.
