Answer:
100 yard = 9144 centimeters
9144 / 3.2 = 2,8575 round off
= 2,858 paperclips
Explanation:
Answer:
There is 61.538% oxygen in Al2(SO4)3.
Explanation:
Wt Of oxygen in the compound = 12*16 = 192 amu.
Total Wt. Of the compound = 2*12+3*32+12*16 = 312 amu.
Thus, percent of oxygen = Wt of oxygen/total Wt. Of compound *100
= 192/312 * 100=61.538 %
Answer:
A lot
Explanation:
- As you go down a group, the elements get larger in size
- All of the elements of the same group have the same # of valence electrons
- As you go to the right of a period, the # of electrons in the outermost shell increases
- The elements at the top right of the table have the highest electronegativity
- Groups 13 through 17 are nonmetals
- The last group contains noble gases
etc.
Most of the common inorganic polyatomic ions<span> have negative </span>charges<span>. This means the </span>ion has<span> more electrons than the neutral atoms that are in the </span>ion<span>. A </span>polyatomic ion<span> like phosphate, PO</span>43- has three<span> extra electrons beyond the electrons on the P and O atoms. Got this off google sorry if it doesn't help you :(</span>
