He did not apply the fifty newtons of greater force! Ok it says when it needed to have the greater force of fifty the person only put 10N out of the fifty, and left out 40N, that is why it did not work properly.
Answer:
10B has 18.9%
11B has 81.1%
Explanation:Please see attachment for explanation
The correct answer is (a)
It is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion.
The explanation:
- the bond between oxygen and phosphorus is covalently.
when A covalent bond is a bond in which electrons are shared. \nd the ionic bond, electrons are completely transferred. In this case phosphate ion (PO4)-3 is covalent.
- that's means that the choice C and D don't be the correct answer.
-Additionally, since the charge is on the oxygen atoms due to the bonding with phosphorus, so we can say that the charge is on the entire ion and not just on the phosphorus atom so,the answer B also not the correct answer.
and the correct one is (A)
Slope is always going to be rise over run. Which in this case is 6/30 which means that the slope is 5.
