A student found a 500 cm3 sample of vinegar. Knowing that vinegar is a solution of ethanoic acid (CH3COOH) and water, this student decided to take a 25.0 cm3 sample, dilute it with 25.0 cm3 of water and then react it with sodium hydroxide. The dilute sample required 37.0 cm3 of 0.850 mol dm–3 sodium hydroxide solution to react entirely with it via the following reaction:
CH3COOH(aq) + NaOH(aq) → NaCH3COO(aq) + H2O(l)
Calculate the concentration of ethanoic acid in the original sample of vinegar.

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.
Answers
Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
[tex]l=0,1,2[/tex]
Magnetic quantum number :
The magnetic quantum number is
[tex]m=-2,-1,0,1,2[/tex]
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:
A. red light or blue light
B. microwaves or radiowaves
C. infrared radiation or red light
D. gamma rays or UV rays
Answers
Answer:
In the first one in a it is red light in b it is radio waves in c it is infrared radiation and d is UV radiation
Explanation:
The forms of radiation from the pairs listed that have longer wavelength are :
A) Red light
B) Radio waves
C) Infrared radiation
D) UV rays
Red light have a wavelength between 650 to 720 nm while a Blue light has a wavelength of 380nm to 500nm which makes it to produce a high energy visible light.( HEV ) light. therefore the Red light has a longer wavelength.
The wavelength of a microwave is approximately 30 centimeters to 1 millimeter, which makes it shorter than the wavelength of a radio wave ( shortest wavelength in the electromagnetic spectrum.
Hence we can conclude that The forms of radiation from the pairs listed that have longer wavelength are A) Red light B) Radio waves C) Infrared radiation D) UV rays

Human body uses the energy provided from food digestion. Endothermic or exothermic?
Answers
Answer:
Endothermic
Explanation:
Exo is outside so exothermic would be outside the body
The carbohydrates are break down into glucose. Then glucose combines with oxygen in the cells and provides energy. Hence, digestion is an exothermic process.
What is an exothermic process ?Food digestion produces heat. This happens as a result of the organism releasing heat during meal digestion. A process that releases heat is exothermic.
Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.
Glucose is created by the breakdown of these carbs. In the cells of our body, this glucose interacts with oxygen to produce energy. So, the process of digesting is exothermic.
Chemical processes involved in food digestion disassemble large food molecules into smaller, more manageable "building block" components.
Thus, Human body uses the energy provided from food digestion is exothermic process.

pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?
Answers
Answer:
Explanation:
chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.
The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.
Information regarding chlorine:chlorine comprises of 7 valence electrons while on other hand, sodium has 1. A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.
