Answer:
4.35 atm
Explanation:
According to the information given;
- Initial volume of the gas, V₁ is 2.50 L
- Initial pressure of the gas is standard pressure P₁, normally 1 atm
- New volume of the gas, V₂ is 575 mL
We are required to determine the new pressure of the gas, P₂ ;
To answer the question, we are going to use the Boyle's law, that relates pressure and volume at constant temperature.
According to Boyle's law;
P₁V₁ = P₂V₂
Therefore, to determine the new pressure, P₂, we rearrange the formula;
New pressure, P₂ = P₁V₁ ÷ V₂
Thus;
P₂ = ( 1 atm × 2.50 L) ÷ 0.575 L
= 4.3478 atm
= 4.35 atm
Therefore, the new pressure of the gas is 4.35 atm
Answer:
Its C how contributions by many different cultures throughout history have advanced our understanding of the solar system.
Explanation:
Answer:
a quantitative observation implies that the subject can be measured by quantity, aka amount or in numbers.
Ex 1: adding one gram of salt to one gram of sugar makes two grams of seasoning. in this example, there are individual quantities (1 gram of each) and total quantity (2 grams). this only changes if the substances have a chemical reaction, such as one of them destroying the other, then the weight would change.
Ex 2: a more simple example is the weight of something. putting the substance on a scale (one specifically for whatever you are measuring, whether it be liquid or solid) is the best way to determine its quantity.
Answer:
Alkenes are <u>Very Reactive</u>.
Explanation:
Other options are incorrect because;
Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.
Single bonds again stands for saturated compounds, hence it is false.
Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.
