They move freely and combine with each other.
Answer:
Mass = 75.6 g
Explanation:
Given data:
Temperature of gas = 17°C
Volume of gas = 575 mL
Pressure of gas = 85000 mmHg
Mass of gas = ?
Solution:
Temperature of gas = 17°C (17+273 =290 K)
Volume of gas = 575 mL (575/1000 = 0.575 L)
Pressure of gas = 85000 mmHg (85000/760 = 111.8 atm)
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
111.8 atm × 0.575 L = n×0.0821 atm.L/ mol.K × 290 K
64.285 atm. L = n×23.809 atm.L/ mol
n = 64.285 atm. L / 23.809 atm.L/ mol
n = 2.7 mol
Mass of nitrogen gas:
Mass = number of moles × molar mass
Mass = 2.7 mol × 28 g/mol
Mass = 75.6 g
Answer:
WAS THE VOOK NAME =THE BOY WHO HARNESSED THE WIND?
1.How did environmental factors affect food production? They could not grow any crops
2. What does William’s windmill allow him to have that he didn’t before? How does life change for him and his family? His windmill allowed him and his family to be able to regrow crops and have unlimited water. Life changes because don’t have to worry about drought issues.
3.Why are trees important to farmers in William’s village? The trees are important because they stop floods. Now whenever it rains the trees can soak up the water.4.Could you imagine living without electricity? What would your life be like? Describe William's life and compare it to American teenagers and even your own. I could not imagine living without electricity. If I lived without electricity, I think my life would be kind of hard at first but after a while I would have to get used to it. William had to depend on the sun for all his light a normal teenager can cut the lights on and off in
Answer:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons. Chemical bonds are formed when the outermost electron shells are not completely filled and atom needs more (or less) electrons to completely fill the outermost shell.
