My professor told me to use a 500ml beaker depending on what your mixing.
The particles are packed closely togetehr but not as tightly as in solids and the particles slide past one another. the particles ahev no regular arrangement, no fixed shape and it takes on the shape of the container it's in. it has a fixed volume and it can't be easily compressed.
If my memory serves me well, correct answer looks like this: If a material, such as diamond, is very strong but gives way (ruptures) quickly when a crack forms, then it is considered <span>c.brittle</span>.
Answer:
5
Explanation:
(2n+1 C + N - H - O)÷2=(9×2+2-10)÷2=5
1) Write the balanced chemical equation
4NH3 + 5O2 ----> 4NO + 6H2O
2) Write the molar ratios
4 mol NH3 : 5 mol O2 : 4 mol NO : 6 mol H2O
3) Write the proportions with the desired quantity of NO and the unknown quantity of O2
5 mol O2 / 4 mol NO = x / 18.0 mol NO
Solve for x: x = 18.0 mol NO * 5 mol O2 / 4 mol NO = 22.5 mol O2
4) Use the ideal gas equation to convert moles to volume
pV = nRT => V = nRT / p
n = 22.5 mol
R = 0.082 atm*liter / K * mol
T = 33 + 273.15 = 306.15 K
p = 874/760 atm = 1.15 atm
V = 22.5 mol * 0.082 atm*liter/K*mol * 306.15 K / 1.15 atm = 491.17 liter
Answer: 491 liters of O2
