Answer:
Chemical bond
Explanation:
Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.
Answer:
1. ions
2. ions
Explanation:
Metals lose electrons and form positive ions (because there are more protons+)
While non-metals gain electrons and form negative ions.(more electrons-)
Answer:
There are 0.1387 moles of oxygen atoms.
Explanation:
First we <u>calculate how many moles of ammonium phosphate there are</u>:
- There are 3 nitrogen moles per (NH₄)₃PO₄ mole.
- There are 0.104 nitrogen moles
- Thus there are (0.104 mol N * ) 0.0347 moles of (NH₄)₃PO₄.
Finally we calculate<u> how many moles of oxygen atoms are there in 0.312 moles of (NH₄)₃PO₄</u>:
- There are 4 oxygen moles per (NH₄)₃PO₄ mole.
- There are 0.0347 moles of (NH₄)₃PO₄.
Thus there are (0.0347 mol (NH₄)₃PO₄ * ) 0.1387 moles of O.
Answer:
False
Explanation:
Groundwater and surface water have a relationship.
Groundwater is the water that is contained in a subsurface layer of an underlying soil/rock whereas surface water is that found in a lake, river or some other surface cavities.
However, when groundwater is discharged to surface water bodies, it is said to be surface water. Thus the statement asked is false.
