Get a magnet in a bag (inside out) and move the magnet all over the sand/iron and you can collect all the iron and turn the bag right side out and zip up the bag. Now you have the sand and iron separated and it will be harder to accidentally mix them later.
Answer:
I got 3/8, hope this helps.
Explanation:
<span>when the number of moles Ca = mass of Ca / molar mass of Ca.
and we can get the molar mass of Ca, it is = 40 g/mol
and we have already the mass of Ca (given) = 9.8 g
so, by substitution: the moles Ca = 9.8 g / 40 g/mol
= 0.245 moles</span>
The butanamide molecule has an asymmetrical distribution of charge.
The molecule has uneven charge distribution<span />
Answer:
The rate of acceleration is 5.
Explanation:
In order to calculate acceleration we need to divide the force by the mass.
Acceleration = net force/mass
In this case, it would be 20/4. Simplify that and we get 5.
