1 mole H2O ------------- 6.02x10²³ molecules
?? moles H2O ---------- 2.0x10²² molecules
( 2.0x10²²) x 1 / 6.02x10²³ => 0.03322 moles
hope this helps!
The person above me is correct I took a test on this so it’s the right answer
2 qualitative: she measures the cupcakes and finds the difference and she estimated that she would get bigger cupcakes if she put more eggs quantitive: she sees that the cupcake with 3 eggs is 0.25 centimeters taller than the cupcake with 2 eggs and she did not get any more extra cupcake even though the cupcake with 3 eggs was taller
Answer:
1200 metric tons = 2645547 pounds
Explanation:
We need to find twelve hundred metric tons of solid waste is how many pounds.
For this, we must know the conversion from metric tons to pounds.
1 metric tons = 2204.62 pounds
To convert 1200 metric tons, multiply 2204.62 by 1200 as follows :
1200 metric tons = 2204.62 × 1200 pounds
= 2645547 pounds
Hence, twelve hundred metric tons of solid waste is equal to 2645547 pounds.
Answer:
- <u><em>B. longer wavelength and equal speed </em></u>
Explanation:
One important feature fo <em>electromagnetic radiation</em> is that all have the same speed in vacuum, <em>c</em><em>,</em> in vacuum, which is the speed of light.
Since, the speed, wavelength and frequency of the waves are related you can infere any of them when the other two are known.
The equation is:
- speed = frequency × wavelength
- c = ν × λ . . . for the specific case of electromagnetic radiation
That inverse relation between frequency and wavelength, where the speed is the constant, shows that the lower the frequency the longer the wavelength.
In conclusion, the correct statment is that an <em>an electromagnetic wave that has a lower frequency will also have a longer wavelength and equal speed (option B).</em>
