Answer:

Faraday's constant will be smaller than it is supposed to be.

Explanation:

If the copper anode was not completely dry when its mass was measured, mass of the copper must be heavier than it should have been. Hence, the calculated Faraday’s constant would be smaller than it is supposed to be since when calculating Faraday’s Constant, the charge transferred is divided by the moles of electrons.

If an object is thrown 60 m into the air and it takes the object 6 s to get there, what's the average speed of the object?
tigry1 [53]

Answer : The average speed of the object is, 10 m/s

Solution : Given,

Distance traveled by the object = 60 m

Time taken = 6 s

Average speed : It is defined as the distance traveled by an object in per unit time. The unit of average speed is, meter/second.

Formula used :

\text{Average speed}=\frac{\text{Distance traveled}}{\text{Time taken}}

Now put all the given values in this formula, we get the average speed of an object.

\text{Average speed}=\frac{60m}{6s}=10m/s

Therefore, the average speed of the object is, 10 m/s

How many moles are in 23.5 g of H20?​
Lorico [155]

Answer:

2.63g

This means that every mole of water molecules will contain 2 moles of hydrogen and 1 mole of oxygen atoms.

To find the percent composition of hydrogen in water, use the molar mass of water and that of hydrogen

2×1.00794g/mol18.0153g/mol×100=11.19%

This means that every 100 g of water will contain a total of 11.19 g of hydrogen. Since your sample has a mass of 23.5 g, it follows that it will contain

23.5g water⋅11.19 g H100g water=2.63 g H

Predict if a solid precipitate will form when solutions of KOH(aq) and Fe(NO3)3(aq) are mixed. If so, identify the solid.
jeyben [28]

Answer:

The answer to your question is KNO₃ is soluble and Fe(OH)₃ is insoluble.

Explanation:

Data

Potassium hydroxide (KOH)

Iron nitrate Fe(NO₃)₃

Double displacement reaction

              3KOH + Fe(NO₃)₃  ⇒   3KNO₃  +  Fe(OH)₃            

Conclusion

KNO₃ is soluble because compounds containing alkali metals ions are

         soluble and also compounds containing nitrate ion are soluble.

Fe(OH)₃ is insoluble because compounds containing OH are insoluble

              except Ba(OH)₂

Samples with masses of 5.5 g 2.27 g and 0.8995 g are mixed together. The sum of the masses of the three
Nadusha1986 [10]

Answer:

m=8.7g

Explanation:

Hello,

In this case, it is widely known that when measurements with different significant figures are put under mathematical operations, the final result must be displayed with the same amount of significant figures of the shortest measurement, thus, due to the fact that 5.5 g has two significant figures only the result is consequently shown with two significant figures as well as shown down below:

m=5.5g+2.27g+0.8995g\\\\m=8.6695g

By rounding the first six to seven due to the fact that the next six is greater than five, according to rounding rules, the result is:

m=8.7g

Best regards.
