Answer:
32. Opcion E
Explanation:
ZO₂ podemos entenderlo como dióxido de Z
1 mol de ZO₂ contiene 1 mol de Z y 2 moles de O₂ por lo que si la masa molar es de 64 g/mol, podemos plantear lo siguiente
Masa de Z + 2 masa de O = 64 g/mol
Sabemos que la masa del oxígeno es 16 g/mol
x + 2. 16 g/mol = 64 g/mol
x = 64 - 32 → 32 g/mol
La masa atómica coincide con la masa molar, por lo tanto la masa atomica de Z es 32.

there are many wanys sediments can be carried so common examples would be... by wind, water, or by animals.
Explanation:
Answer:
47.2%
Explanation:
Judging from the question given, the theoretical yield is 10g because the student had already made his/her calculation and was expecting to get the same result at the end of the experiment. But he could only get 4.72g from the experiment.
Now, The percentage yield can be obtain as follows
Experimental yield = 4.72g.
Theoretical yield = 10g
%yield = Experimental yield /Theoretical yield x100
% yield = 4.72/10 x100
%yield = 47.2%
Therefore, the percentage yield of the experiment is 47.2%
The answer is -33.6 degree Celsius... or approximately-34 degree Celsius. Firstly, you will change the L to mL so 2.10L to mL is 2100ML.. so if 750ML=-12 degree Celsius then 2100ML is what?? So.. if more less divide.. so 2100ML/750ML *-12 =-33.6 degree Celsius.. approximately -34 degree Celsius. I hope it helped??
