Answer:

Explanation:
Hello,
In this case, given the balanced reaction:

We can see a 2:4 mole ration between permanganate ion (118.9 g/mol) and manganese (IV) oxide (86.9 g/mol), that is why the resulting mas of this last one turns out:

Best regards.
 
        
             
        
        
        
Answer:
The answer is <u>applied research</u>
Explanation:
Pure research becomes <u>applied research</u> when scientists develop a hypothesis based on the data and try to solve a specific problem. 
This is because the pure research try to understand, predict or explain the behavior of different phenomena <em>(the data)</em> while the applied research try to develop new technologies or methods (<em>hypothesis)</em> to take part, intervene and/or create changes on these phenomena and solve a <em>specific problem.</em>
 
        
             
        
        
        
Answer: 581 gmol
0.581 kmol

Explanation: 
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number  of particles.
 of particles.
To calculate the moles, we use the equation:

1. The conversion for mol to gmol
1 mol = 1 gmol
581 mol= 
2. The conversion for mol to kmol
1 mol = 0.001 kmol
581 mol= 
3. The conversion for mol to lbmol
1 mol = 
581 mol=
