Answer:
volume = 13097674418.528dm³
Explanation:
n = (3.52)*10^32/(6.02)*10^23)
n = (584717607.97)
n = volume /molar volume
molar volume at stp = 22.4dm³
volume= 584717607.97 x 22.4
volume = 13097674418.528dm³
Carbon has four valence electrons. Meaning, it has 4 electrons in it's last shell. These 4 electrons will form a covalent bond with other elements to get the full set of 8 electrons needed for it to be stable. That is why it's considered as tetravalent.
Momentum = Mass x Velocity
80kg Runner: 80 x 2.45 = 196 Kg m/s
65kg Runner: 65 x 3= 195 Kg m/s
The 80kg runner has a greater momentum
Answer:
Explanation:
The chemical reaction involved is as follows
H₃BO₃ + 4HF = HBF₄ + 3H₂O
1 mol 1 mol
mol weight of H₃BO₃ is 61.84 gm
50g = 50 / 61.84 mol.
= 0.8 mol.
.8 mol of H₃BO₃ will form .8 mol of BF₄⁻ ion .
“Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes”.
