Answer:
Phalanges
Explanation:
Phalanges are located in both the hands (the bones that make up the fingers) and the feet (the bones that make up the toes)
2 C3H6 + 2 NH3 + 3 O2 -> 2 C3H3N + 6 H2O
Molar masses
C3H6: 42.08 g/mol
NH3: 17.03 g/mol
O2: 32 g/mol
CH3H3N: 53.06 g/mol
H2O: 18 g/mol
# of moles
C3H6: 15.0 g / [42.08 g/mol] = 0.356 mol
NH3: 5.00 g / [17.03 g/mol] = 0.294 mol
O2: 10.0 g / [32 g/mol] = 0.313 mol
Now wee need to find the limitant reactant
The theoretical proportion is 2:2:3, equivalent to 1:1:1.5
The proportion ot the given gases is 0.356 : 0.294 : 0.313, dividing by 0.294 that is equivalent to: 1.2 : 1 : 1.06, where you see that O2 is below the theoretical proportion and it is the limitant reactant.
Now, from the equation you have 3 mol of O2 produces 2 mol of acrylonitrile (C3H3N)
Then you will obtain 0.313 * 2/3 = 0.209 mol acrylonitrile
The mass is 0.209mol * 53.06 g/mol = 11.07 g acrylonitrile
Answer: 11.07 g
Answer: Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass, occupies 22.4 L at STP contains avogadro's number of particles.
Molecular mass of protein = 480,000 g/mol
Thus 1 mole of protein weighs = 480,000 g
So 27 moles of protein weighs =
Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
A solid
I'm adding a ton of characters down here so they let me post my answer.
Answer:
Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.
