Answer:
Physical Change
Explanation:
The bush is changing shapes, not changing what it is.
Answer:
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas. 2 moles of nitrogen monoxide gas react with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
Explanation:
Answer:
36.693
Explanation:
From the question given, the following were obtained:
Let 35Cl be isotope A and 37Cl be isotope
For isotope A (35Cl),
Mass number = 34.9700
Abundance = 13.85 %
For isotope B (37Cl),
Mass number = 36.9700
Abundance = 86.15 %
Atomic mass =
[( Mass of AxAbundance A)/100] + [(Mass of BxAbundance B)/100]
[(34.97x13.85)/100] + [(36.97x86.15)/100]
= 36.693
1. %yield = actual yield / theoretical yield x 100
= 3 g / 4. 46 g x 100
= 62.11 % percent yield
Hope This Helps! :3
This would probably be based on the number and type of chemical bonds the substance has.
