Answer:
116.1 a.m.u.
It is not likely that RCOOH is the pentanoic acid
Explanation:
Let's consider the generic neutralization between NaOH and a monoprotic carboxylic acid.
RCOOH(aq) + NaOH(aq) ⇒ RCOONa(aq) + H₂O(l)
The molar ratio of RCOOH to NaOH is 1:1. The moles of RCOOH are:
The molar mass of RCOOH is:
Thus, the molecular weight is 116.1 a.m.u.
Pentanoic acid has the formula C₅H₁₀O₂ with a molecular weight of 102.1 a.m.u. So, it is not likely that RCOOH is the pentanoic acid.
Answer:
The new volume of the gas decreased in to 0.329llL
The question is another language. Translation in English language is as following:
What are the common sensors that can be used to identify metal, gas or liquid?
Answer:
<u>Common sensors that can be used to identify metal, gas or liquid are as following:</u>
- Inductive Proximity Sensor: Inductive proximity sensors are able to detect metals only. It generates output signal or electrical signal when any metal object come nearby its sensing area.
- Handheld flammable gas detectors: they are commonly used to detect gas leakage such as natural gas lines, butane tanks, or any other combustible gas.
- Optical level sensors: this sensor is used to detect liquids including the interface between two immiscible liquids and the occurrence of sediments.
