Answer:
wood, flour and plastic
Explanation:
Not soluble means insoluble which means that a substance does not or cannot dissolve in water. examples are
wood, flour and plastic
Answer:
The total amount of heat released is 68.7 kJ
Explanation:
Given that:
mass of water = 94.0 g
moles of water = 94 / 18.02 = 5.216
80⁰C ------> 0⁰C --------> -30⁰C
Q1 = m Cp dT
= 94 x 4.184 x (0 - 80)
= -31463.68 J
= -31.43 kJ
Q2 = 6.01 x 10^3 x 5.216
= - 31348.16 J
= -31.35 kJ
Q3 = - 94 x 2.09 x 30
= - 5893.8 J
= -5.894 kJ
Total heat = Q1 + Q2 + Q3 = -31.43 kJ + (-31.35 kJ ) + (-5.894 kJ
) = -68.7 kJ
Total heat released = -68.7 kJ
Note that the "negative sign" simply indicates heat released, therefore no need to put it in the answer.
Answer:
The word equation is:
This reaction happens when there is the decomposition of hydrogen peroxide into oxygen and water. Thus, the equation would be
Balancing the equation requires to have the same number of atoms of each element on both the side. To balance this equation we need to add 2 water () molecules and 2 hydrogen peroxide () molecules . As we know, oxygen is naturally diatomic. Thus, the balancing equation would be:
I believe that it would be attracted to objects with an opposite charge. Hope this helped!
