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 :

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

Therefore, the average speed of the object is, 10 m/s
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
Answer:
1, 3, 2
Explanation:
1 x N2 = N2
3 x H2 = H6
2 x NH3 = N2H6
which is balanced, I believe.
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
Answer:

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:

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:

Best regards.
