Answer:
1.5
Explanation:
It is given that:
Compound A and B originate from Sulfur + Oxygen.
Compound A:
6g sulfur + 5.99g Oxygen
Compound B:
8.6g sulfur + 12.88g oxygen
By comparing the ratios:
Compound A:
S: O = 6.00: 5.99
S/0 = 6.0g S / 5.99g O
Compound B:
S: O = 8.60: 12.88
S / O = 8.60g S / 12.88g O
The mass ratio of A and that of B
(6.0g S / 5.99g O) ÷ (8.60g S / 12.88g O)
(6.0 g S / 5.99g O) × (12.88g O / 8.60g S)
(6 × 12.88) / (5.99 × 8.60)
= 77.28 / 51.514
= 1.50017
= 1.5
Answer:
Calcium's atomic radius is roughly 175 pm.
Explanation:
We know that magnesium has an atomic radius of 150 pm.
The atomic radius of strontium measures 200 pm.
Since calcium's position is between magnesium and strontium in group 2 of the periodic table, its atomic radius should be roughly averaged between magnesium's and strontium's atomic radii because atomic radius is not constant.
Thus;
Calcium's atomic radius is approximately calculated as follows;
The average atomic radius is (200 + 150)/2 = 175 pm.
Answer: The energies of infrared photons are comparable to those linked with various vibrational states of chemical bonds. Molecules can absorb infrared photons of specific wavelengths, highlighting the types and strengths of different chemical bonds present within the molecules.
Explanation:
Infrared spectroscopy evaluates the vibrational energy states found in molecules. When a molecule absorbs infrared photons, the chemical bonds vibrate at distinct frequencies. Scrutinizing the alterations in vibrational energy within a molecule allows for the identification of different bond types and consequently the molecule’s general structure. The vibrational behaviors of a molecule encompass bending, stretching, and scissoring motions.
H2PO4- acts as a proton donor, whereas HPO42- serves as a proton acceptor. Step 1: Determining hydrogen ion donors and acceptors in the reaction displayed: H2PO4- is predisposed to release a H+ ion to yield HPO42-. On the other hand, HPO42- is inclined to accept a H+ ion, producing H2PO4-. The process of an acid in a water solvent is characterized as dissociation: HA ⇔ H+ + A- where HA denotes a proton acid. Therefore, H2PO4- = HA and HPO42- = A-. Acids are recognized as proton donors, which is why H2PO4- donates protons and HPO42- accepts them.
Answer:
Explanation:
Considering the reaction: 2X + 3Y = 3Z, combining 2.00 moles of X with 2.00 moles of Y results in the production of 1.75 moles of Z.
2 mol 2 mol 1.75 mol
2X + 3Y = 3Z
2 mol is required with 3 mol to yield 3 mol.
3 mol Z / 3 mol Y = 1 to 1
should yield 2 mol Z
1.75 / 2 = 87.5 % production yield
