Answer:
212.996 or 213 approx.
hope it helps.
Molar mass of Al - 27
Molar mass of N - 14
Molar mass of O - 16
so, the molar mass of (No3)3 will be (14+16×3)3 which is equals to 186.
so, Molar mass of Al(No3)3 will be 186+27 = 213.
Answer:
C: Object 1 is moving, and Object 2 is not moving
Explanation:
Object one has unbalanced forces, so it can cause it to start moving ,since one force is moving stronger than its opposing one, but since Object 2 has balanced forces both forces hold it in place.
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
