Answer:
The answer is : Yes
Explanation:
because it 12:00 and the storm is moving at 25km/hr and it 75 km away that means in three hours the storm would hit your town so at 3:00 the storm would hit at your at ends at 2:00 so yes you would get home before he storm hit.
Answer:
It releases nutrients which causes rapid growth of planktons which leads to oxygen deficiency leading to death of aquatic animals,a phenomenon known as eutrophication.
Explanation:
Answer:
The exposure time that equals 750 is 3.4 hr
Explanation:
The given formula is:
![[tex]T=.0002*x^{2} -.316*x+127.9](https://tex.z-dn.net/?f=%5Btex%5DT%3D.0002%2Ax%5E%7B2%7D%20-.316%2Ax%2B127.9)
[/tex]
In the formula:
T= exposure time
x= carbon monoxide present in ppm
So, to calculate the exposure time when carbon monoxide is 750ppm, you should replace the "x" by 750.
![[tex]T=.0002*750^{2} -.316*750+127.9](https://tex.z-dn.net/?f=%5Btex%5DT%3D.0002%2A750%5E%7B2%7D%20-.316%2A750%2B127.9)
[/tex]
T=3.4hr
When the balanced reaction equation of methane combustion is:
CH4 + 2O2 →CO2 + 2H2O
so, we can see that each 1 mole of methane combusted will give 2 moles of water as a product.
so first, we need to get the moles of methane =
= mass of methane /molar mass of methane
= 52.6 g / 16.04 g/mol
= 3.28 moles
when 1 mol of methane produces→ 2 moles of water
∴ 3.28 moles methane produces → X moles of water
∴ moles of water = 3.28 * 2
= 6.56 moles
when each 1 mole of water has 6.02 x 10^23 (Avogadro's number ) individual molecules:
∴number of molecules of water = 6.56 * 6.02 x 10^23
= 3.9 x 10^24 molecules
Answer:
3.01×10²⁴ atoms
Explanation:
Our compound is the Na₃PO₄
Sodium phosphate.
We assume, we have 5 moles of the mentioned salt.
1 mol of anything contains 6.02×10²³ atoms.
That's the Avogadro's number. The conversion is:
5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms
