Answer:
4.55 * 10^23 molecules
Explanation:
This is a conversion problem. We know that one mole has 6.022 *10^23 particles or molecules so we can use this as a conversion factor.
0.755 mol ( 6.022*10^23 molecules/ 1 mol)
=4.55*10^23 molecules
gain, you add anything to the beaker there's going to be a gain in weight since there's more stuff there
Using coupons seems like an old-fashioned, time-consuming way to save a few cents on the products you buy at the grocery store. After all, most coupons don't usually have a face value of more than $1 and, quite often, they're worth far less. But done properly, couponing can save you thousands of dollars every year.
Answer:
its speeding up but not at a constant speed
Explanation:
Answer: No charge (0)
Explanation:
The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.
So, if this atom gains 3 more electrons, the net charge would be zero (neutral).
The total number of electron would now be 22 which is the same as the proton number.
This implies the atom is now in an unreacted state or ground state.
