Answer:
New volume is 14.35 mL
Explanation:
When a system of a gas keeps on constant its temperature and number of moles, the pressure is modified indirectly proportional to the volume:
Pressure increased → Volume decreased
Pressure decreased → Volume increased.
The relation you have to apply is: P₁ . V₁ = P₂. V₂
1.23 atm . 35 mL = 3 atm . V₂
(1.23 atm . 35 mL / 3 atm) = V₂
V₂ = 14.35 mL
Answer:
a chemical compound
Explanation:
copper(ii) chlorate is a chemical compound of the transition metal copper and the chlorate anion with basic formula cu(cio)3 and 2
Answer:
Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.

Answer:
The product would have more acidity than Diethyl malonate
Explanation:
For this question, first, we have to start with the structure of the bromination reaction. <u>The bromination would add a "Br" atom</u> in the middle carbon between the ester groups. Therefore, the molecule produced would be <u>diethyl 2-bromomalonate</u> and the formula of this compound fits with the reported by the question:
Now, if we have to analyze the acidity we have to check the <u>most acidic hydrogen</u>. In this case, is the "H" in the middle carbon (red hydrogen). In the Diethyl malonate, we have an <u>inductive effect</u> caused by the carbonyl groups on each side of the middle carbon. In the diethyl 2-bromomalonate, we have this same inductive effect plus the Br atom bonded to the same carbon. Therefore, would be <u>easier to remove the hydrogen</u>. So, diethyl 2-bromomalonate would ba more acidity than Diethyl malonate.
See figure 1
