The visual representation of the above reaction is depicted in the attached image.
<h3>What is a reaction?</h3>
A chemical reaction is a process that converts one or more compounds, known as reactants, to one or more distinct substances, known as products.
Chemical elements or compounds are examples of substances.
A chemical reaction, as seen in the accompanying image, rearranges the component atoms of the reactants to produce distinct substances as products.

Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
There are five key factors involved when cleaning that are equally important: time, temperature, mechanical action, chemical reaction and procedures. Balancing these factors will produce the best possible results.
The answer is C.
