<span>The option A is correct answer. The isotopes are X and Y. The isotopes are those which have same atomic number but different mass number. Since atomic number has same number of protons or electrons. Thus, isotopes have same number of protons or electrons. Therefore, X and Y are isotopes.</span>
Answer:
B and C
Explanation:
powder dissolve faster than particles
the higher the temperature the faster the dissolving process
Answer:
Z³⁺
Explanation:
The ion symbol can be depicted as Z³⁺ .
In this atom, the number of protons is 27 and the number of electrons is 24.
Protons are the positively charged particles within an atom.
Electrons are the negatively charged particles within an atom.
To find the charge;
Charge = Number of protons - number of electrons
Charge = 27 - 24 = +3
The atom is positively charged and it can be depicted as Z³⁺
The answer is yes I believe so.
Convert metres to feet:
343m*3.28f = 1,125.04ft/s
There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.
1,125.04ft*3600s = 4,050,144 ft/h
Now, since you asked for miles, convert to miles (5280 ft in a mile):
4,050,144ft/5,280m = 767.072mph
That is your answer! Hope I helped. :)
