The difference between mass and time is the influence of the earth's gravitational force on objects
<h3><em>Further explanation</em></h3>In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter in the matter, whereas weight is a force that leads to the center of the earth which is subject to the earth to matter (Earth's gravitational force)
So that the mass does not depend on the location of the object, while the weight can change depending on the position of the object
In international standards, the mass unit is kg while the weight is in units of newton
1 kg itself is the mass of a cylinder made of platinum-iridium
While the standard mass of an atom is determined according to the carbon-12 atomic mass of 12 atomic mass units
1 atomic mass unit comparable to 1.6605402.10-17 kg
Measuring the atomic mass using a mass spectrometer.
The mass itself can be measured by the arm balance while the weight is measured by the spring balance
One equation that can relate mass and force (weight) is
W = m.g
W = weight, N
m = mass, kg
g = gravity acceleration, m / s2

Answer:
The value of the heat capacity of the Calorimeter = 54.4
Explanation:
Given data
Heat added Q = 4.168 KJ = 4168 J
Mass of water = 75.40 gm
Temperature change = ΔT = 35.82 - 24.58 = 11.24 ° c
From the given condition
Q = ΔT +
ΔT
Put all the values in above equation we get
4168 = 75.70 × 4.18 × 11.24 + × 11.24
611.37 = × 11.24
= 54.4
This is the value of the heat capacity of the Calorimeter.
Answer:
Explanation:
In this reaction, we must exchange the amino group () for a fluorine atom (
). Also, the first step in this reaction is the addition of nitrous acid.
We must remember that the amino group in the presence of nitrous acid produces a diazonium salt. The group is a very good leaving group and many benzene derivatives can be produced from this intermediate (see figure 1).
If what we want is to bond a fluorine atom we must use to be able to produce m-ethylfluorobenzene (see figure 2).
I hope it helps!
