Answer:
The correct option is;
24 moles
Explanation:
Here, we have the reaction as follows;
Sn(s) + 2HF(g) → SnF₂ (s) + H₂ (g)
Therefore, one mole of Sn reacts with 2 moles HF to form one mole of SnF₂ and one mole of H₂
Molar mass of H₂ = 2.01588 g/mol
Therefore, the number of moles of H₂ in 48 grams of H₂ is given by the relation;
Since one mole each of SnF₂ and H₂ are produced, the number of moles of SnF₂ produced = 24 moles.
The number of moles of SnF₂ that will be produced is 24 moles.
<span>The correct formula for Beryllium phosphate is Be3(PO4)2
Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6
-6 + +6 = 0</span>
Answer: hopefully this is right UwU
Explanation: The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the transmitted light reveals how much energy was absorbed at each frequency (or wavelength).
C₁ * V₁ = C₂ * V₂
18 * V₁ = 6.0 * 250
18 V₁ = 1500
V₁ = 1500 / 18
V₁ = 83.33 mL
hope this helps!
