16.7
Explanation:
Given parameters:
Force applied to Jack = 120N
Force produced by Jack = 2000N
Unknown:
Mechanical advantage of jack = ?
Solution:
Mechanical advantage is the ratio of force produced by the device and the force applied on it.
It is used to access the performance of a machine.
M.A = \frac{force output}{force input}
Now input the parameters;
M.A =
M.A = 16.7

Answer:
Coefficient of
Coefficient of =8
Explanation:
We are given that a reaction in which reacts with
We have to find the coefficient of each reactants in balanced reaction
Coefficient is defined the constant value multiplied with a reactant in a reaction.
Coefficient of =3
Coefficient of
Coefficient of
Coefficient of
Coefficient of
Coefficient of KOH=2
Hence, Coefficient of and coefficient of
The number that represents the coefficient on the product side of the chemical reaction, is 7.
In equations representing chemical reactions, the coefficient of each reactant or product of a reaction is the number that comes on the left-hand side just before the chemical formula.
The coefficient of each species in a chemical reaction is obtainable when the equation of the reaction is balanced.
For example, in the following equation: 2A + B = 3C + D
The coefficients of A, B, C, and D are 2, 1, 3, and 1 respectively.
Applying this to the product side of a chemical reaction;
It means that the coefficient of the product is 7.
