Which is a base-conjugate acid pair? NH3 and CIO
ozzi

Answer:

The pair will be:

- NH3/NH4⁺

- ClO⁻/HClO

Explanation:

A conjugate acid is formed after a base has reacted/accepted a proton.

Since H2O is amphiprotic, we can use it as the acid.

NH3 + H2O ⇄ NH4⁺ + OH⁻

ClO⁻ + H2O ⇄ HClO + OH⁻

after reacting, the base form conjugate acid.

using the equation you wrote determine how many moles of butane c4h10 are needed to react with 5.5 moles of oxygen
GaryK [48]

Answer:

0.846 moles.

Explanation:

  • This is a stichiometric problem.
  • The balanced equation of complete combustion of butane is:

C₄H₁₀ + 6.5 O₂ → 4 CO₂ + 5 H₂O

  • It is clear from the stichiometry of the balanced equation that complete combustion of 1.0 mole of butane needs 6.5 moles of O₂ to produce 4 moles of CO₂ and 5 moles of H₂O.

<u><em>Using cross multiplication:</em></u>

  • 1.0 mole of C₄H₁₀ reacts with → 6.5 moles of O₂
  • ??? moles of C₄H₁₀ are needed to react with → 5.5 moles of O₂
  • The number of moles of C₄H₁₀ that are needed to react with 5.5 moles of O₂ = (1.0 x 5.5 moles of O₂) / (6.5 moles of O₂) = 0.846 moles.

Which scientific investigation describes a field study?
weqwewe [10]

Answer:

A. A scientist investigates a mouse's growth in nature by watching the animal.

A field study is a raw collection of data, typically in the natural habit of the organism; hence why an experiment taken in a lab isn't a field study.

Which substance is an example of a nonpolar compound?(1 point)
Tatiana [17]
The answer is B - vegetable oil.

Explanation:

The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.

Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.

Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.

Polar liquids, like water, do not dissolve non-polar liquids like oil.
