What will happen if we conduct the experiments below: 1) In a solution NaOH we add phenolophthalein and later we add HCl.

2) In a vinegar solution we add soda.

3) In a HCl solution we add an amount of copper.​

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

you gotta add the following molecules so we can give u an answer

explanation:

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
