The answer is argon, hope this helps!
Well, if you are moving forward in a direction, then your velocity is your speed with the direction you are moving in. To calculate velocity, you divide your distance traveled by the time it took to travel that distance and you add your direction to it.
So to conclude, 300/100= 3 m/s South
Mitochondria because is the power house for cell,site for respiration or energy release.
At STP, it is at 273 K and 1.00 atm.
Use PV=nRT to and solve for n (number of mol of N2)
1.00 atm • 4.40L / 0.08206 Latm/molK • 273 K = 0.196 mol N2
There are two mol of N2 for every two mol of NH4NO2 (the number of mol of both are equal)
Find the molar mass of NH4NO2 = 64.1 g
Multiply the number of mol by the molar mass
0.196 mol • 64.1 = 12.6 g NH4NO2
The Lithosphere ("rock sphere") is the ground you are standing on and the whole inside of Earth.
The Hydrosphere ("water sphere") includes all of the rivers, lakes and oceans of Earth.
The Cryosphere ("icy cold sphere") is the frozen part of Earth: the glaciers, icebergs at sea, and the huge icecaps in Greenland and Antarctica.
The Biosphere ("Life sphere") includes all living things: the trees in the park, the birds in the air, the fly on your wall, the viruses that make you sick, your pets, and even you and all your friends!
The Atmosphere ("Air Sphere") is the envelope of air that surrounds the whole Earth.
The Exo- or Celestial Sphere ("Outside or heavenly sphere") includes the whole universe beyond the top of the atmosphere--the Sun, Moon, and stars, as well as the asteroids and the little bits of dust that make meteors when they hit the atmosphere.
