2.50 x 2/1 = 5 mol of Citric Acid
5 x (3+72+5+112) = 960g of Citric Acid
Answer: 960g of Citric Acid
Oak tree, because it’s the primary producer
Answer:
nine
There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals. The five different orientations of orbitals in the 3d subshell are shown in the figure below.
Explanation:
Answer:
0.15g
Explanation:
Given parameters:
Number of molecules of water = 1.2 x 10²¹ molecules
Unknown:
Mass of SnO₂ = ?
Solution:
To solve this problem, we have to work from the known to the unknown specie;
SnO₂ + 2H₂ → Sn + 2H₂O
Ensure that the equation given is balanced;
Now,
the known species is water;
6.02 x 10²³ molecules of water = 1 mole
1.2 x 10²¹ molecules of water =
= 0.2 x 10⁻²moles
Number of moles of water = 0.002moles
From the balanced chemical equation:
2 mole of water is produced from 1 mole of SnO₂
0.002 moles of water will be produced from
= 0.001moles
To find the mass;
Mass = number of moles x molar mass
Molar mass of SnO₂ = 118.7 + 2(16) = 150.7g/mol
Mass = 0.001 x 150.7 = 0.15g
Answer:
For the provided compounds, by decreasing chemical shift (ppm), the sequence from left to right is Benzene >> Cyclohexane >> Ethane (CH₂-CH₂) >> Methane (CH₄).
Explanation:
¹H-NMR spectrum, roughly, we can say that the more density of electron around the Hydrogen atom, the lower the shift is. So, in this case methane with the simplest structure, only one Carbon atom, does not cause much effect to reduce the density of electron around the hydrogen, so, it is the lowest.
Ethane and cyclohexane looks similar, but cyclohexane with the ring-structure, six carbon atoms, has more effect than ethane with only 02 carbon atoms. Benzene, with the aromatic ring, which has very strong negativity with electron, so it cause the density of electron on the surrounding hydrogen to be the lowest among the four provided compounds.
