Answer:
To test the accuracy of a hypothesis or any findings that have already been made
Explanation:
by performing experiments scientists get to test out any questions they have
160 g of SO3 are needed to make 400 g of 49% H2SO4.
<h3>How many grams of SO3 are required to prepare 400 g of 49% H2SO4?</h3>
The equation of the reaction for the formation of H2SO4 from SO3 is given below as follows:
1 mole of SO3 produces 1 mole of H2SO4
Molar mass of SO3 = 80 g/mol
Molar mass of H2SO4 = 98 g/mol
80 g of SO3 are required to produce 98 og 100%H2SO4
mass of SO3 required to produce 400 g of 100 %H2SO4 = 80/98 × 400 = 326.5 g of SO3
Mass of SO3 required to produce 49% of 400 g H2SO4 = 326.5 × 49% = 160 g
Therefore, 160 g of SO3 are needed to make 400 g of 49% H2SO4.

Hear n = 1000 to n = 2 pairs of quantum states of hydrogen has the biggest energy difference between the states
A quantum state is a mathematical concept used in quantum physics that gives a probability distribution for the results of each potential experiment on a system. All that can be predicted about the behaviour of the system is exhausted by knowledge of the quantum state and the laws governing the system's evolution across time. Another quantum state is a combination of quantum states. All other quantum states are known as mixed quantum states, whereas pure quantum states are those that cannot be described as a combination of other states. A ray in a Hilbert space over the complex numbers can represent a pure quantum state, but density matrices, which are positive semidefinite operators acting on Hilbert spaces, can represent mixed states.To know more about ray, visit to: -brainly.com/question/17491571#SPJ4
True
Explanation:
Magnetism is the ability of a material to be attracted by a magnet or to act like a magnetic material.
- Magnetism is exhibited by a wide range of substances.
- In fact, the earth behaves like a bar magnet.
- A magnet usually have a magnetic field round them and they exert their forces in this regions.
- Magnets are used for a wide range of functions like in fans and rotors.
- Substances can lose their magnetic ability when exposed to high temperatures and electrically.
