Answer:
The attractive force between them decreases
Explanation:
This is because they become localised.
Explanation:
Carbon-12 atoms have stable nuclei because of the 1:1 ratio of protons and neutrons.
Carbon-14 atoms have nuclei which are unstable. C-14 atoms will undergo alpha decay and produce atoms of N-14. Carbon-14 dating can be used to determine the age of artifacts which are not more than 50,000 years old.
Answer:
Mass of
produced = 32 g
Explanation:
Calculation of the moles of
as:-
Mass = 82.4 g
Molar mass of
= 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-

2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of
produced = 32 g</u>
Answer:
D. 60.3 kilometers per hour
Explanation:
Hello,
In this case, we first compute the miles in kilometres:

Then the minutes in hours:

Finally, the velocity:

Thus, answer is D. 60.3 kilometers per hour
Best regards.
