Effusion is the escape of a gas through a small hole.
Graham Law states that the speed of effusion is inversely related to the square root of its molar mass:
effusion speed = K * 1 / √ molar mass)
=> effusion speed of gas A √(molar mass of gas B)
--------------------------------- = ----------------------------------
effusion speed of gas B √(molar mass of gas A)
=> efussion speed of Ne √(83.8)
----------------------------- = ---------- = 2.04
effusion speed of Kr √(20.18
=> effusion speed of Ne = 2.04 * effusion speed of Kr.
Answer: approximated twice.
Answer:
8.20 % → Percent yield reaction
Explanation:
To find the percent yield of reaction we apply this:
(Produced yield / Theoretical yield) . 100 = %
Produced yield = 112.9 g
Theoretical yield = 1375.5 g
We replace → (112.9g / 1375.5 g) . 100
8.20 % → Percent yield reaction
Answer:
Tin and Copper
Explanation:
The two atoms that could potentially form alloys are the tin and copper atoms.
Alloys are mixtures formed between two or more metals.
The goal of forming alloys is to take properties of one metal and add to that of another metal so as to enhance both materials.
Alloys are only formed between metals.
The only metal pair given from the choices is that of tin and copper.
Therefore, the two atoms that could potentially form alloys is tin and copper.
Answer:
D. TTACGCCAGG. that would be your answer.
Answer: Option C. p-dichlorobenzene and 1,4-dichlorobenzene.
Explanation:
A line-angle formula with six vertices and a circle inscribed corresponds to the compound known as benzene.
Further, according to the IUPAC standards for naming benzene derivatives, you must first number the position of the substituent. In this case, the substituents (chloros) are located at the positions 1 and 4; also, for the benzene derivatives when they have 2 substituents and the positions are 1 and 4, this configuration is known as <em>para </em>or <em>p </em>configuration.
Additionally, this compound has 2 substituents (chloros) so you have to indicate this number (di).
Therefore, the correct answer is C. p-dichlorobenzene and 1,4-dichlorobenzene.
