2H2O=2H2+O2
37.4g H2O(1 mol/18.02)=2.07547 mol H2O
PV=nRT
(1.30)(V)=(2.07547)(.0821)(297)
Vwater=38.92898L
38.92898L (1 mol O2/2 mol H2O)=19.46449L O2 gas
The answer is; D
Diffraction of light occurs when the light encounters an obstruction that is smaller than its wavelength. The water droplets in the clouds can be very small and be closer in size to the wavelength of light. When sunlight encounters a cloud droplet, light waves are altered and interact with one another in a similar manner as the water waves causing fringes of light around clouds.
Answer:
True
Explanation:
The force gets weaker as you move further away from the nucleus. Therefore, the electrons in the outermost energy level have the most energy
Answer:
6.9428 kg of CO2
Explanation:
1) Use Avogadro's number that states 1 mole = 6.022 x 10^23 particles. Convert 9.5 x 10^25 molecules into moles.
9.5 x 10^25 CO2 molecules = 157.75 moles CO2
2) Convert 157.75 moles of CO2 into grams. CO2's molar mass is 44.01g.
= 6942.79g
3) Convert 6942.79 grams into kilograms (divide by 1000):
6.9428 kg
Answer:
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
Explanation:
we have aluminum that is added to nickel (ii) nitrate solution. Nickel (ii) means here nickel having electron charge of +2 . NO₃ having electron charge -1. So nickel nitrate solution be (NO₃)₂
Aluminium on reaction replaces nickel and form Aluminium Nitrate with some amount of nickel. After balancing both side
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
