Answer:

Idk

Explanation:

Find the gallons needed by dividing total miles by miles per gallon:

4700/41 = 114.634 gallons

Multiply the gallons needed by price per gallon:

114.634 x 2.79 = $319.83 Total

Round the answer as needed.

If gallons were rounded to 115 gallons total cost would be $320.85

  • Answer:

<em> $ 434.40</em>

  • Explanation:

<em>41 miles ............ 1 gallon</em>

<em>4700 miles .......x gallon</em>

<em>x = 4700×1/41 = 114.63 gallons</em>

<em />

<em>114.63 gallons×$3.79 ≈  $ 434.40</em>

A sample of an unknown substance has a mass of 0.158 kg. If 2,510.0 J of heat is required to heat the substance from 32.0°C to 6
Alexxandr [17]
Specific heat capacity is the required amount of heat per unit of mass in order to raise teh temperature by one degree Celsius. It can be calculated from this equation: H = mCΔT where the H is heat required, m is mass of the substance, ΔT is the change in temperature, and C is the specific heat capacity.

H = m<span>CΔT
2501.0 = 0.158 (C) (61.0 - 32.0)

C = 545.8 J/kg</span>·°C

Given the ion C2O4-2, what species would you expect to form with each of the following ions?
Ksivusya [100]

Answer:

A. K₂C₂O₄          Potassium oxalate

B. CuC₂O₄          Copper oxalate

C. Bi₂(C₂O₄)₃         Bismuth (III) oxalate

D. Pb(C₂O₄)₂         Lead (IV) oxalate

E. (NH₄)₂C₂O₄       Ammonium oxalate

F. HC₂O₄⁻             Acid oxalate

Explanation:

C₂O₄⁻²  → oxalate anion

This is the conjugate base from the H₂C₂O₄ which is the oxalic acid. A weak dyprotic acid that can release 2 protons.

A. 2K⁺  +  C₂O₄⁻²  → K₂C₂O₄          Potassium oxalate

It can be formed by the neutralization of the acid with the base

H₂C₂O₄  + 2KOH  → K₂C₂O₄  +  2H₂O

B. Cu²⁺ +  C₂O₄⁻²   ⇄  CuC₂O₄  ↓

This is a precipitate.

C.  2Bi³⁺  +  3C₂O₄⁻²   ⇄  Bi₂(C₂O₄)₃  ↓

This is a precipitate.

D.  Pb⁴⁺ +  2C₂O₄⁻²   ⇄  Pb(C₂O₄)₂  ↓

This is a precipitate.

E. 2NH₄⁺  +  C₂O₄⁻²   ⇄  (NH₄)₂C₂O₄  ↓

This is a precipitate.

F. This is the conjugate strong base, for the weak acid

H⁺  +  C₂O₄⁻²   ⇄  HC₂O₄⁻

HC₂O₄⁻  + H₂O  ⇄  C₂O₄⁻²  +  H₃O⁺    Ka

HC₂O₄⁻  + H₂O  ⇄  H₂C₂O₄  +  OH⁻    Kb

HC₂O₄⁻  is an amphoteric compound

Explain why the column of a fractional distillation apparatus should be aligned as near to the vertical as possible
____ [38]
<span><span>The column of a fractional distillation apparatus should be aligned vertical to get better separation because the column is essentially longer. It will prevent channeling in the column. </span>Therefore column efficiency will be higher if it is as vertical as possible instead of tilted.<span> Distillation is a process used to separate a mixture of two (or more) components. In a typical </span>fractional distillation, a liquid mixture is heated in the distilling flask and the process begins.</span>

What is the mole ratio of NH3 to N2?
Ksenya-84 [330]
To answer this question a balanced chemical equation is necessary. The correct equation is: N2 + 3H2 = 2NH3
From this equation, one mole of nitrogen react with 3 moles of hydrogen to give 2 moles of ammonia.
Therefore, the mole ratio of NH3 to N2 is 2:1
