Answer:
The atoms have been rearranged. To put it another way, it created a new substance.
Answer:
See below.
Step-by-step explanation:
The author is probably reminding us that knowing the origins of words helps us to remember what they mean.
If "verde" means "green", the "verd" in "verdigris" probably means that verdigris is green.
However, the "verd" in verdigris domes from other languages.
It was originally Latin "viride aeris" (green brass).
In old French it became "verte de Grèce" (green of Greece). The modern French spelling is "vert-de-gris" (green of grey).
The English word "verdigris" comes from the French words.
Answer:
(slow)xy2+z→xy2z (fast) c step1:step2:xy2+z2→xy2z2
Explanation:
Step1: xy2+z2→xy2z2 (slow)
Step2: xy2z2→xy2z+z (fast)
2XY 2 + Z 2 → 2XY 2 Z
Rate= k[xy2][z2]
When the two elementary steps are summed up, the result is equivalent to the stoichiometric equation. Hence, this mechanism is acceptable. The order of both elementary steps is 2, which is ‘≤3’; this also makes this mechanism acceptable. Furthermore, the rate equation aligns with the experimentally determined rate equation, and this also makes this mechanism acceptable. Therefore, since all the three rules have been observed, this mechanism is possible.
Answer:
the overall charge on the nitride anion is

Since nickles atomicnumber is 28, that means it has 28 protons, which are positively charged. To cancel out the positive charge and make it nuetral, there isalso 28 electrons which are negatively charged.
Nickel has 31 neutrons because an atoms mass is the number of protons + neutrons. The # of protons is 28. The mass # is 59. So, there are 31 neutrons.
