Answer: X3Y2
Explanation:
The formula is
X has a valency of 2
Y has a valency of 3
So, we interchange the valencies
Therefore, the formula is
X3Y2
Answer:
-) Acid-base reaction
-) Carboxylic acid, alcohol, alkene and ketone
Explanation:
For the reaction between acetic acid and triethylamine, we will have an <u>acid-base reaction</u>. Therefore a s<u>alt would be produced</u> in this case an <u>"ammonium quaternary salt"</u>. Also, we have to remember that on this reaction the acid is the acetic acid and the base is the triethylamine. See figure 1
For the second question, we have to check the <u>structure of Prostaglandin</u> E1 in which we have the functional groups:
<u>1) Carboxylic acid</u>
<u>2) Alcohol</u>
<u>3) Alkene</u>
<u>4) Ketone</u>
See figure 2.
I hope it helps!
Answer:
315 g
Explanation:
Step 1: Write the thermochemical equation
2 H₂O(l) → 2 H₂(g) + O₂(g) ΔH = +572 kJ
Step 2: Calculate the molar of water decomposed by 5.00 × 10³ kJ of energy
According to the thermochemical equation, 572 kJ are required to decompose 2 moles of water.
5.00 × 10³ kJ × (2 mol/572 kJ) = 17.5 mol
Step 3: Calculate the mass corresponding to 17.5 moles of water
The molar mass of water is 18.02 g/mol.
17.5 mol × 18.02 g/mol = 315 g
Answer:
Dilute 1 ml of 2M solution to 100 ml
Explanation:
C₁V₁=C₂V₂
V₁=C₂V₂/C₁=
=100×0.02/2=1ml
