Answer:
electrons
Explanation:
because it rotates the nucleus around it
Answer:
3 atoms of O
8.57g
Explanation:
The problem here is to find the mass of oxygen in the compound and the number of atoms of oxygen.
The formula of the compound is:
NaHCO₃;
Here we have:
1 atom of Na
1 atom of H
1 atom of C
3 atoms of O
So there are 3 atoms of O
To find the mass of oxygen , we use the molar mass of oxygen;
Molar mass of oxygen = 16g/mol
Mass of oxygen =
x 15 = 8.57g
Answer : The average speed of the object is, 10 m/s
Solution : Given,
Distance traveled by the object = 60 m
Time taken = 6 s
Average speed : It is defined as the distance traveled by an object in per unit time. The unit of average speed is, meter/second.
Formula used :

Now put all the given values in this formula, we get the average speed of an object.

Therefore, the average speed of the object is, 10 m/s
Answer: atom
Explanation:
It makes the most sense to me anyways seeing that an atom contains protons electrons and neutrons in it already
