Answer:
These predictions are likely to be valid and should be needed.
Explanation:
Meteorologist made predictions about weather of a particular area on the data they received from the satellite. Meteorology is a branch of science in which we study about the atmosphere. It is mainly used for the forecasting of weather and meteorologists are those people or scientists who study the weather and research on different scales or instruments of weather.
The result of the procedure is that the copper strip should go through oxidation.
<h3>How to explain the procedure?</h3>
The copper strip should be considered as the anode and the nail should be considered as the cathode.
The anode is the electrode of an electrochemical cell at which oxidation occurs. The anode should be + while the cathode should be negative. Both should be placed in the tank that should be filled with the electrolyte solution.

M(Li₃PO₄)=115.8 g/mol
c(Li⁺)=0.175 mol/L
v=500 mL= 0/5 L
n(Li⁺)=3n(Li₃PO₄)=3m(Li₃PO₄)/M(Li₃PO₄)=c(Li⁺)v
m(Li₃PO₄)=c(Li⁺)vM(Li₃PO₄)/3
m(Li₃PO₄)=0.175*0.5*115.8/3=3.3775* g
*Solubility lithium phosphate in water about 0,34 g/L. Litium phosphate can be dissolved in solution of a phosphoric acid. For example:
2Li₃PO₄(s) + H₃PO₄(aq) = 3Li₂HPO₄(aq)
Answer:
When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.
Explanation:
<em>Which of the following statements is TRUE? </em>
- <em>Electrons placed in antibonding orbitals stabilize the ion/molecule.</em> FALSE. Electrons in the antibonding orbitals destabilize the ion/molecule.
- <em>The total number of molecular orbitals formed doesn't always equal the number of atomic orbitals in the set.</em> FALSE. The total number of molecular orbitals is always equal to the number of atomic orbitals in the set.
- <em>When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.</em> TRUE. The orbital with lower energy will be the bonding orbital and the one with higher energy will be the antibonding orbital.
- <em>A bond order of 0 represents a stable chemical bond.</em> FALSE. A chemical bond is stable if the bond order is higher than zero.
