The balanced equation for the reaction is as follows
2RbNO₃ --> 2RbNO₂ + O₂
stoichiometry of RbNO₃ to O₂ is 2:1
number of moles of RbNO₃ decomposed - 5.0 mol
when 2 mol of RbNO₃ decomposes, 1 mol of O₂ is formed
therefore when 5.0 mol of RbNO₃ decomposes - 5.0 / 2 = 2.5 mol of O₂
2.5 mol of O₂ is formed
Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products.
<u>Explanation</u>:
- The carbon cycle is the procedure where carbon goes from the surrounding into living beings and to the Earth and then again goes into the air. Plants take carbon dioxide from the air and use it for food preparation. Creatures at that point eat the nourishment and carbon is put away in their bodies or discharged as CO2 through the breath.
- Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products. This is known as carbon storage.
- For instance, carbon, a fundamental component in natural particles, is preserved as it is moved from inorganic carbon in a biological system to natural atoms in living life forms of the biological system and back as inorganic carbon to the earth.
Answer:
pH = 6.80. The aqueous solution is slightly acid
If pH is 7.00 at 37°C, solution is neutral
Explanation:
2H₂O ⇄ H₃O⁺ + OH⁻ Kw = 2.4×10⁻¹⁴
To determine the pH of a solution, we must consider the [H₃O⁺]
[H₃O⁺] . [OH⁻] = 2.4×10⁻¹⁴
[H₃O⁺] = [OH⁻] → √2.4×10⁻¹⁴ = [H₃O⁺]
1.55×10⁻⁷ = [H₃O⁺]
pH = - log 1.55×10⁻⁷ = 6.80
pH = 7 → neutral
pH < 7 → acid
pH > 7→ basic

Multiply then divide 12g by 4cm3 because 4cm3 equals 64cm divide by 12g or multiply which ever is in the options
