Answer:propanoic acid
Explanation:
Carboxylic acids contain the COOH group. This group is capable of hydrogen bonding leading to association of the molecules. Cyclobutane is a cyclic alkane and acetone is a ketone. Non of these compounds posses a polar -OH bond which is necessary for the occurrence of hydrogen bond. Hydrogen bonds only occur in carboxylic acids and alcohols. Hydrogen bond leads to molecular association and high boiling points.
Answer: element
Explanation:
It only has one type of atom making it a element

Answer:
Hypothesis and Data Collection
Part A-i think the glass with cold water will have more of a air bubble effect then the one with hot water
Part B-The glass with cold water is having more of a reaction but the water level in both of them are the same
Part C-yes, the glass with cold water had more of a reaction then the one with hot water
Analyze and Extend
Part A-yes, the glass with cold water had more of a reaction then the one with hot water
Part B-Becuase the reaction in the cold water was greater than the one in the hot water we can come to the conclusion that CO2 has a higher solubility in cold water
Part C-the soda that was left in the refrigerator wil have more "fizzing and bubbles" becuase it has higher solubility then the one left in the hot sun
Part D-There is now too much CO2 in the atmosphere and the tempertaures will continue to increase (this is why the summer time is hotter then the rest of the year)
Ik i was late to answer this but can you please give me brainliest
Answer:
The following statement is true
When 137.14 g PCl₃(l) react, 304.0 kJ are consumed.
Explanation:
The given equation is
Molecular weight of
PCl₃ = 137.14
P₄ = 123.88
The enthalpy is positive which means the reaction is endothermic.
The reaction will absorb energy from the surroundings.
A) When 1 mol PCl₃(l) reacts, 304.0 kJ are released: False, energy is being absorbed not released
B) When 1 mol P₄(s) is produced, 304.0 kJ are consumed: False as the reverse reaction will be exothermic and there will be release of energy during formation of phosphorus.
C) When 548.56 g PCl₃(l) react, 304.0 kJ are released: Energy is being consumed so it is false
D) When 137.14 g PCl₃(l) react, 304.0 kJ are consumed:True as the enthalpy of reaction is 304.0 kJ
E) When 123.88 g P₄(s) are produced, 304.0 kJ are released: Energy is being consumed so the statement is False.
