Answer:

Step-by-step explanation:
A scatter plot is a two-dimensional data visualization that uses dots to represent the values obtained for two different variables one plotted along the x-axis and the other plotted along the y-axis.
A regression line is a straight line that describes how a response variable y changes as an variable x changes. It is the relation between two variables x and y.
Here,
x = day of a week 
y = number of visitors
The given data points are 
Plotting the scatter plot and regression line in Excel, the following is generated which is attached further below.
The regression line is,

Comparing it with the general slope-intercept form  ,
,
slope = 
 
        
                    
             
        
        
        
The place value is a hundred thousand, as there are 5 digits following the eight.
        
             
        
        
        
100g of ammonia releases 271.18 kJ of heat.
<u>Explanation:</u>
Given:
N₂ reacts with H₂
The reaction is:
2N₂ + 3H₂ → 2NH₃ + 92.2 kJ
According to the balanced reaction:
2 X 17g of ammonia releases 92.2 kJ of heat
34g of ammonia releases 92.2 kJ of heat
100g of ammonia will release =  kJ of heat
 kJ of heat
                                                  = 271.18 kJ
Therefore, 100g of ammonia releases 271.18 kJ of heat.
