Answer:
A is the molecular formula for xylose because shows the actual number of atoms in the compound: Formula B is the empirical formula for xylose because it shows the smallest whole-number ratio for the different atoms in the compound: Formula A is the molecular formula for xylose because shows the arrangement of atoms in the compound: Formula B is the structurab formula for xylose because it shows the smallest whole-number ratio for the different atoms in the compound: Formula A is the empirical formula for xylose because it shows the actual number of atoms in the compound: Formula B is the molecular formula for xylose because it shows the smallest whole-number ratio for the different atoms in the compound: Formula A is the structural formula for xylose because it shows the arrangement of atoms in the compound: Formula B is the empirical formula for xylose because it shows the smallest whole-number ratio for the different atoms in the compound.
Answer:
0.29
Explanation:
Since the name of the acid (and the equation) is not given, you must assume that it is a 1:1 ratio. Use equation: volume of acid x molarity of acid = volume of base x molarity of base (when the ratio is 1:1).

Answer:
The final volume of air after compression: V₂ = 4477.63 L = 158.12 cf
Explanation:
Given: Initial gauge pressure of the gas = 0 psi
Initial absolute pressure of the gas: P₁ = gauge pressure + atmospheric pressure = 0 psi + 12.20 psi = 12.20 psi
Initial Temperature = 70°F
⇒ T₁ = (70°F − 32) × 5/9 + 273.15 = 294.26 K
Initial volume of the gas: V₁ = 1200 cf = 1200 × 28.317 = 33980.4 L (∵ 1 cf ≈ 28.317 L)
Final gauge pressure of the gas = 90 psi
Final absolute pressure of the gas: P₂ = gauge pressure + atmospheric pressure = 90 psi + 12.20 psi = 102.2 psi
Final Temperature: T₂ = 125°F
⇒ T₂ = (125°F − 32) × 5/9 + 273.15 = 324.82 K
Final volume of the gas: V₂ = ? L
<u>According to the </u><u>Combined gas law</u><u>:</u>

→ 
→ 
→ 
<u>Therefore, the final volume of air after compression: </u><u>V₂ = 4477.63 L = 158.12 cf</u>
Answer: The correct answer is option D.
Explanation:
Mercury is occurs in earth crust but its mining ,combustion of fossil fuel and extraction had led to spreading of mercury pollution not only on lands but in air and water bodies also.
Mercury settled on land get washed way into water bodies which further gets introduced in life process of living beings in the water and eventually effecting the whole food chain or web.
Hence, from the the given options the correct option is (D).
