Answer:
Aluminum is a shiny, silvery white colored metal that is light in weight and strong. Th density of aluminum is 2.7 g/mL, which means the metal will sink in water, but is still relatively light
Hope this helps (:
Mark me brainliest if its good for you :D take care.
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
Explanation:
The balanced chemical reaction between copper (II) oxide and carbon monoxide is producing cooper and carbon dioxide:
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
where:
(s) - solid
(g) - gas
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

Answer: Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.
so C would seems to be right.
Explanation: The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.
1. minimize
2. not buy the insurance
3. too expensive in relation to the value of his vehicle
HCl is a strong acid and KOH is a strong base. HCl dissociates to form H⁺ ions and Cl⁻ ions and KOH dissociates to give out K⁺ and OH⁻ ions.
When H⁺ and OH⁻ ions react they form H₂O molecules which are neutral.K⁺ ions and Cl⁻ ions form KCl salts.
the balanced equation for the reaction is as follows
HCl + KOH ----> KCl + H₂O
products are therefore KCl and H₂O
