Answer:
496 g
Explanation:
Let's consider the reaction between ethanol and oxygen to form acetic acid and water.
CH₃CH₂OH + O₂ → CH₃COOH + H₂O
The molar ratio of CH₃CH₂OH to CH₃COOH is 1:1. The moles of acetic acid produced by the reaction of 8.26 moles of ethanol are:
8.26 mol CH₃CH₂OH × (1 mol CH₃COOH/1 mol CH₃CH₂OH) = 8.26 mol CH₃COOH
The molar mass of acetic acid is 60.05 g/mol. The mass corresponding to 8.26 moles is:
8.26 mol × 60.05 g/mol = 496 g
<u>Answer: </u>The correct statement is X is the effective nuclear charge, and it increases across a period.
<u>Explanation:</u>
We are given that:
X = number of protons − number of core electrons
Effective nuclear charge is defined as the actual nuclear charge (Z = number of protons) minus the screening effect caused by the electrons present between nucleus and valence electrons. These electrons are the core electrons.
The formula used for the calculation of effective nuclear charge given by Slater is:
where,
= effective nuclear charge
Z = atomic number or actual nuclear charge or number of protons
= Screening constant
The effective nuclear charge increases as we go from left to right in a period because nuclear charge increases with no effective increase in screening constant.
Hence, the correct answer is X is the effective nuclear charge, and it increases across a period.
If the container is closed, all vapor generated by boiling will stay in the container. If it is at constant volume, the pressure will rise in it. ... Heat pipes boil a liquid at one end and condense it at the other. So the system can remain closed because the contents don't increase: you put in heat, you take out heat.
Answer:
The false statement is d Avery,Macleod and McCarty showed that DNA is the genetic information of cells and RNA is the genetic information in the viruses .
Explanation:
Avery,Macleod and MacCarty showed that DNA is the genetic material of the cell.
On the other hand Fraenkel, Conrat and Sanger carried out their experiment on tobacco mosaic virus to prove that RNA act as genetic material in some viruses.
Answer:
fiber
Explanation:
Soluble fiber easily dissolves in water and is broken down into a gel-like substance in the part of the gut known as the colon. Insoluble fiber does not dissolve in water and is left intact as food moves through the gastrointestinal tract
i hope this is right and if not i tried my best to help
