Answer:

Newton's First Law of Motion: Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.

Newton's Second Law of Motion: The rate of change of momentum is directly proportional to the force applied in the direction of force.

Newton's Third Law of Motion: There is an equal and opposite reaction for evrey action

Newton's First Law of Motion: Any article stays in the condition of rest or in uniform movement along a straight line, until it is constrained to change the state by applying outside power.  

Newton's Second Law of Motion: The pace of progress of energy is legitimately relative to the power applied toward power.  

Newton's Third Law of Motion: There is an equivalent and inverse response for evrey activity

Answer:

Weathering involves the use of water and or wind to wear down the environment. The sand dunes were most likely carried by wind to form them and form its shape. Erosion most likely took away parts of the sand to make the sand dune. Deposition most likely deposited sand to the area.

How does the volume of water change the solubility of sodium chloride in simple words?
kupik [55]

Answer:

When sodium chloride dissolves in water to make a saturated solution there is a 2.5 per cent reduction in volume. ... The solubility of salt does not change much with temperature, so there is little profit in using hot water.

What is the percentage yield of O2 if 12.3 g of KClO3 (molar mass 123 g) is decomposed to produce 3.2 g of O2 (molar mass 32 g)
My name is Ann [436]

Answer:

The percentage yield of O2 is 66.7%

Explanation:

Reaction for decomposition of potassium chlorate is:

2KClO₃ →  2KCl  +  3O₂

The products are potassium chloride and oxygen.

Let's find out the moles of chlorate.

Mass / Molar mass = Moles

12.3 g / 123 g/mol = 0.1 mol

So ratio is 2:3, 2 moles of chlorate produce 3 mol of oxygen.

Then, 0.1 mol of chlorate may produce (0.1  .3)/ 2 = 0.15 moles

Let's convert the moles of produced oxygen, as to find out the theoretical yield.

0.15 mol . 32 g/ 1mol = 4.8 g

To calculate the percentage yield, the formula is

(Produced Yield / Theoretical yield) . 100 =

(3.2g / 4.8g) . 100 = 66.7 %
