Answer:
$13,500
Explanation:
The differential analysis of the proposal to replace the commercial oven is shown below:-
The Total differential decrease in cost = Annual maintenance cost reduction × Number of years applicable
= $23,000 × 5
= $115,000
Inflow cash = The Total differential decrease in cost + Proceeds from sale of equipment
= 115,000 + $8,500
= $123,500
The Net differential decrease in cost from replacing equipment = Inflow cash - Cost of new equipment
= $123,500 - $110,000
= $13,500
the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
Hope this helps ^^
E = m c²
where E = energy released
m = mass of the nucleus
C= velocity of light
m = 9.106 x 10⁻³ x 1.67 x 10⁻²⁷ kg
C = 3 x 10⁸ m/s and C² = 9 x 10¹⁶
E = 1.37 x 10 ⁻¹² J
Answer:
addition of HNO3 HNOX3 to Cu - Aueous
addition of H2SO4 HX2SOX4 to CuO - Aqueous
addition of Z n Zn to C u S O 4 CuSOX4 - Solid
addition of N a O H NaOH to C u ( N O 3 ) 2 Cu(NOX3)X2 - Solid
heating of C u ( O H ) - Solid
Explanation:
Copper when introduced with acids form an aqueous solution and fumes are released in air during the chemical reaction. When NaOH is added to copper then solid copper product is released. Copper dissolves on HNO but does not dissolves in HCL.

Tell me if I'm wrong because I'm kind of bad at chemistry
