486 kPa will be the pressure of gas at 27 degrees.
Explanation:
Data given :
Initial pressure of the gas P1 = 810 kPa
initial temperature of the gas T1 = 227 degrees OR 500.15 K
final pressure of the gas =?
final temperature of the gas = 27 degrees OR 300.15 K
Gay Lussac's law is used to calculate the pressure of the gas at 27 degrees or 300.15 K
= 
P2 = 
Putting the values in the equation:
P2 = 
P2 = 486 KPa
486 Kpa is the pressure of the gas when temperature was reduced to 27 degrees.
The answer is phototropism, which is the growth of an organism responding to the presence of light.
Answer:
C: Carbon monoxide - Acidic nature
Explanation:
A) Beryllium is not soluble in water but yet it reacts with an acid and a base. Therefore, since it exhibits both basic and acidic nature, we say it is Amphoteric in nature. Thus it is correct
B)potassium super oxide has the formula KO2. It reacts with acid to form salt called potassium chloride. Thus, it is basic in nature.
C) Carbon monoxide does not react with acids or bases. Thus, it doesn't show either an acidic or basic property and we say it is a neutral oxide. This option is incorrect
D) Bismuth oxide is a basic oxide because it displays properties of a base. This options is correct
Answer:
It is better to use direct quotation rather than summarizing or paraphrasing when you want to share the author's original words.
Explanation:
In writing, it is sometimes necessary to share an authors original words in order to buttress a point or validate an argument. In such cases where it is necessary to use exactly the same diction as the author in order to communicate a point clearly, it is apt to use a direct quotation rather than attempting to summarize or paraphrase the original words of the author.
Hence direct quotation is used to share an author's original words.
Answer:
If you are asking why the atomic mass on the periodic table only goes to the hundredth's place, it is because of significant figures. No number is exact, like it can be 63.5500001, and it will go to a certain point before it cease to matter in experiments.
