Concentrated ammonia solution gives off ammonia gas. Concentrated hydrochloric acid gives off hydrogen chloride gas. Ammonia, NH³ and hydrogen chloride, HCI , are both colourless gases. ammonia reacts with hydrogen chloride to make the white solid ammonium chloride 1.at which point A, B,C or D does the white solid form? Explain why the white solid forms at that point

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

level 4 to level 2 : ))

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
