Alina [70]4 years ago
7 0

Answer:

The answer is "False".

Explanation:

The given statement is false, which can be defined as follows:

  • Molarity is focused on solution liters, which is focussed on kg of solvents when analyzing the property of solutions related to vapor temperature.
  • Its pressure variations, quantities represented in molar concentration can be used.  
  • It is used when its meaning doesn't change with temperature changes. It can be calculated as the M1 x V1 = M2 x V2.

What is the empirical formula of the compound that is 25.3% magnesium and 74.7% chlorine
Margarita [4]

Answer: MgCl_2

Explanation:

25.3% Mg

74.7% Cl

First step: change % to g

25.3g Mg

74.7g Cl

Second step: calculate g/mol of each compound. You can do this by using the atomic mass.

25.3gMg(\frac{1mol}{24.30g})=1.04mol

74.7gCl(\frac{1mol}{35.45g} )=2.11mol

Third step: determine the lowest number and divide everything by it. Of the result, extract whole number only.

Mg=\frac{1.04}{1.04} =1

Cl=\frac{2.11}{1.04}=2

Fourth step: Write each compound with their respective number below.

This empirical formula should be: MgCl_2

What did rutherford learn about the atom from his gold-foil experiment?
cluponka [151]
Hi there!

Rutherford's experiment showed that the atom's nucleus <em>did </em>have a positive charge. The α particles' trajectory was altered when it went through the gold foil, which, in turn resulted in the discovery of the atom's positive charge.

I hope this helps!
