Answer:
The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
The Law of conservation of mass governs the balancing of a chemical equation.
According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the produc
It is very important for scientists to replicate each other experiment because this will help to determine if important scientific results are repeatable. The correct option is A. Scientific results presented by a scientist should be reproducible anywhere in the world, without this, the results can not be accepted as theory.
Answer:
Set small goals for yourself
Explanation:
the goals you start with do not need to be huge, break down the goal Into smaller tasks. this is a system called metronome growth system.
For the average speed of blood flow in the major arteries of the body is mathematically given as
v2 = 117.29m/s
<h3>What is the average speed of blood flow in the major arteries of the body?</h3>
Generally, the equation for the average speed is mathematically given as
A1 v1 = A2 v2
(pi r1^2) v1 = A2 v2
(3.14x(1.4)^2 )x 40 = (2.1) xV2
v2 = 117.29m/s
In conclusion, the average speed of blood flow
v2 = 117.29m/s
