Answer: I believe it should be 224g.
Explanation: There are 40g for every one mole of NaOH, so multiply the two to get to 224. I hope that helps!
 
        
                    
             
        
        
        
<h3><u>Answer;</u></h3>
Cellulose 
<h3><u>Explanation</u>;</h3>
- Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
- <em><u>It  is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
- <em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very  strong.</u></em>
- The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.
 
        
        
        
There are many properties to substances.
I'll list some examples below:
- Mass
- Volume
- Density
- Conductivity
- Malleability
- Boiling point
- Melting point
- Heat capacity
Hope this helps! :3
 
        
             
        
        
        
Answer:
Quantity A is weight and Quantity B is mass
Explanation: weight has same unit as force. Mass is the quantity of matter present in a body or object 
 
        
                    
             
        
        
        
Answer:
a. 342.9 kJ of heat are absorbed.
Explanation:
Calculation of the moles of  as:-
 as:-
Mass = 20.00 g
Molar mass of  = 17.031 g/mol
 = 17.031 g/mol
The formula for the calculation of moles is shown below:
 
Thus,
 

Given that:- 
It means that 1 mole of  undergoes reaction and absorbs 1168\ kJ of heat
 undergoes reaction and absorbs 1168\ kJ of heat
So, 
1168 mole of  undergoes reaction and absorbs
 undergoes reaction and absorbs  of heat
 of heat
<u>Amount of heat absorbed = + 342.9 KJ</u>
