The compound magnesium phosphate has the chemical formula mg3(po4)2. in this compound, phosphorous and oxygen act together as one charged particle, which is connected to magnesium, the other charged particle. what does the 2 mean in the formula 5mg3(po4)2?

The 2 mean in the formula that there 2 phosphates ion in single molecule of magnesium phosphates.

Explanation:

Subscript numbers are defined as the number of atoms of each element present in a compound.

Superscript numbers are defined as the charges of ions reacting in a chemical reaction.

The chemical formula of magnesium phosphate is given as:

The numeral '2' in the subscript out of the bracket enclosing phosphate ion indicates that there are two phosphate ions in 1 molecule of magnesium phosphate. In which two phosphates ions are linked to single magnesium atom.

And numeral '5' in front of indicates that there are 5 molecules of  magnesium phosphate.Numeral written before the molecular formula of any compound in chemical reaction are also termed as coefficient.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
