Observation of experiment and intervention in newton's optics. newton followed the principle of light through prisms and the rays transmitted through them as a part of his observation. Various properties of light and its characteristics were exposed.
Explanation:
- Newton's investigation of light was based on prisms, lenses and optical rays.
- He stated that lights differing in colour also differed in degrees of re-frangibility.
- To support his theories newton employed "Proof by experiments" method. Each method was designated in revealing a specific property of light.
- A phenomenon known as Newton rings were discovered by newton.
- Newton recognized after pressing together two prisms that there was a transparent spot.
1. Answer;
=56 g/mol
Explanation and solution;
PV = nRT
nRT= mass/molar mass (RT)
molar mass = (mass/V ) × (RT/P)
= Density × (RT/P)
Molar mass = 2.0 g/L × (0.0821 × 323 K)/0.948 atm
Molar mass = 56 g/mol
2. Answer;
Molecular mass is C4H8
Explanation;
Empirical mass × n = molar mass
Empirical mass for CH2 = 14 g/mol
Therefore;
56 g/mol = 14 g/mol × n
n = 4
The molecular formula= 4(CH2)
= C4H8
It stays roughly the same size. Electrons have a barely imperceptible mass so the overall mass of the atom is changed very little.
Answer:
the open bag allowed the gas from the reaction to escape
A catalyst will ALWAYS increase the reaction rate so C
