The acceleration : 0.25 m/s²
<h3>Further explanation</h3>
Given
mass = m = 24 kg
Force = F = 6 N
Required
The acceleration
Solution
Newtons' second law :
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
ΣF = m x a
Input the value :
6 N = 24 kg x a
a = 6 : 24
a = 0.25 m/s²
<span>This question asksyou to apply Hess's law.
You have to look for how to add up all the reaction so that you get the net equation as the combustion for benzene. The net reaction should look something like C6H6(l)+ O2 (g)-->CO2(g) +H2O(l). So, you need to add up the reaction in a way so that you can cancel H2 and C.
multiply 2 H2(g) + O2 (g) --> 2H2O(l) delta H= -572 kJ by 3
multiply C(s) + O2(g) --> CO2(g) delta H= -394 kJ by 12
multiply 6C(s) + 3 H2(g) --> C6H6(l) delta H= +49 kJ by 2 after reversing the equation.
Then,
6 H2(g) + 3O2 (g) --> 6H2O(l) delta H= -1716 kJ
12C(s) + 12O2(g) --> 12CO2(g) delta H= -4728 kJ
2C6H6(l) --> 12 C(s) + 6 H2(g) delta H= - 98 kJ
______________________________________...
2C6H6(l) + 16O2 (g)-->12CO2(g) + 6H2O(l) delta H= - 6542 kJ
I hope this helps and my answer is right.</span>
Answer:
<h3>it is hydrogen gas </h3>
3. the chemical equation is :
MgSO4 ( s ) + H2SO4 (aq)-->
MgSO4 (aq) + CO2 (g) + H2O (I)

<u>Answer:</u> The mass of plastic sheet is 
<u>Explanation:</u>
The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.0 m = 1000 cm (Conversion factor: 1 m = 100 cm)
b = breadth of cuboid = 1.0 m = 100 cm
h = height of cuboid = 1 cm
Putting values in above equation, we get:
To calculate mass of a substance, we use the equation:
We are given:
Density of plastic sheet = 
Volume of plastic sheet = 
Putting values in equation 1, we get:
Hence, the mass of plastic sheet is
