Why is it better to give the actual speed of an object rather than to simply say it moved fast or it moved slowly

1 answer:

3 0

Specificity. It’s really loose to say that something is fast, since speed can be scalarly linked and relative. I could say that both a car on the highway is fast, but so is the speed of light. The actual speed of something helps to do away with the arbitrary nature of using “fast” and “slow”; however, we’re still at step one of the person who is receiving the information is unfamiliar with the scale that the actual speed is defined in.

Use the equation 2cu+o2=2cuo to find how many miles of copper react to form 3.64 mil cuo

Firlakuza [10]

<h3><u>Answer;</u></h3>

3.64 moles

<h3><u>Explanation;</u></h3>

From the equation;

2Cu + O2 → 2CuO

Mole ratio of Cu : CuO = 2: 2 equivalent to 1: 1

Moles of CuO = 3.64 Moles

Therefore;

moles of Cu will be ;

3.64 × 1 = 3.64 moles

Moles of Cu = <u>3.64 moles </u>

Will the water level of the sea increase when there is global warming

alexdok [17]

Global warming will cause see levels to rise since a lot of water is stored in ice sheets which will melt. All of the melt water will end up in the ocean causing sea levels to rise.

I hope this helps. Let me know if anything is unclear.

If 45 mL of water are added to 250 mL of a 0.75 M K2SO4 solution, what will the molarity of the diluted solution be?

krok68 [10]

Answer:

$\large\boxed{\large\boxed{0.64M}}$

Explanation:

When you form a <em>diluted solution</em> from a mother (concentrated) solution, the moles of solute are determined by the mother solution.

The main equation is:

$Molarity=\dfrac{\text{moles of solute}}{\text{volume of the solution in liters}}$

Then, since the moles of solute is the same for both the mother solution and the diluted solution:

$\text{Molarity mother solution }\times\text{ volume mother solution}=\\\\=\text{Molarity diluted solution }\times\text{ volume diluted solution}$

Substitute and solve for the molarity of the diluted solution:

$250mL\times 0.75M=(45mL+250mL)\times M\\\\\\M=\dfrac{250mL\times 0.75M}{295mL}=0.64M$
