Thomson in 1897 was the first to suggest that one of the fundamental units was more than 1,000 times smaller than an atom, suggesting the subatomic particle now known as the electron. Thomson discovered this through his explorations on the properties of cathode rays.
Answer:
43.2 mol C
115 mol H
158 mol of atoms
Explanation:
Step 1: Given data
Moles of C₃H₈: 14.4 mol
Step 2: Calculate the number of moles of C
The molar ratio of C₃H₈ to C is 1:3. The moles of C are 3/1 × 14.4 mol = 43.2 mol.
Step 3: Calculate the number of moles of H
The molar ratio of C₃H₈ to H is 1:(. The moles of H are 8/1 × 14.4 mol = 115 mol.
Step 4: Calculate the total number of moles of atoms
n = nC + nH = 43.2 mol + 115 mol = 158 mol

Explanation:
The reaction between magnesium and hydrochloric
acid combine to form a salt of magnesium chloride and release hydrogen
gas. This single replacement reaction is a classic example of a metal
reacting in an acid to release hydrogen gas.
Answer:
I think you can make 26, hope this helped.
Explanation:
Answer:
Explanation:
In this problem, we need to convert 
to miles per hour
We know that,
1 mile = 1.609 km
1 hour = 3600 seconds
Hence,
