Finger [1]

Answer:

a. size and composition

Explanation:

The inner planets differs from the outer planets mostly and mainly in terms of their sizes and composition.

Inner planets are also know as the terrestrial planets. They are the first four planets closest to the sun. They are mostly solids with rocky masses.

The outer planets are located beyond the asteroid belts. They are the last four planets before the Kuiper belt objects. These planets are also called Jovian planets predominantly made up of gases.

The inner planets are smaller compare to the outer planets in size.

The outer planets are gas giants and the inner planets are rocky masses.

A 14.1% by mass HClO3 solution has a density of 1.1690 g/mL. What is the concentration of this solution in molarity?
Scilla [17]

Answer:

[ HClO₃] = 1.93M

Explanation:

X % by mass, means that in 100 g of solution, we have X g of solute.

In this case, 14.1 g of HClO₃ are contained in 100 g of solution.

Density always referrs to solution. Let's calculate the volume of solution.

Solution density = Solution mass / Solution volume

1.1690 g/mL = 100 g / Solution volume

Solution volume = 100 g /1.1690 g/mL → 86.2 mL.

For molarity we must get moles of solute and volume of solution (L), because molarity is mol/L

Let's convert the mL of solution in L

86.2 mL . 1L / 1000mL = 0.0862 L

Now, let's determine the moles of solute. (Mass / Molar mass)

14.1 g / 84.45 g/mol = 0.167 moles

Molarity is mol/L →  0.167 moles / 0.0862 L = 1.93M

An experiment was conducted to see which metal pot would be better for cooking food quickly. The table below shows how quickly s
KengaRu [80]

Answer : It is a conclusion.

Explanation:

Conclusion: It is a judgement or decision which can be attained by reasoning.

From the observation table given we can conclude that :

  • Aluminum ,bronze and steel took 27,45 and 80 seconds to melt small piece of wax respectively which means that more time will be required by them to transfer heat to the food while cooking. Hence,  food will take more time to cook in them.
  • Copper took less time of 15 seconds to melt the small piece of wax in comparison to other metal pots which means that it is a good conductor of heat in comparison to other. Hence, copper pot would be better for cooking food quickly.

After analyzing the observations and results in an experiment conclusion was made that copper pots are best for cooking foods.
