Answer : The heat of the reaction is -221.6 kJ
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter
where,
= heat released by the reaction = ?
= heat absorbed by the calorimeter
= specific heat of calorimeter = 
= change in temperature = 
Now put all the given values in the above formula, we get:
As,
So, 
Thus, the heat of the reaction is -221.6 kJ
Answer:
Explanation:
The crabs cannot see the plankton they eat near the ocean floor. For the crabs to see the plankton, some color of visible light would need to reach the plankton so that it can be reflected into the crabs' eyes.
The answer is Photosynthesis!
Answer: Employments of friction based electricity incorporate contamination control, Xerox machines, and painting. They utilize the property that inverse electrical charges pull in. There are different utilizations including the properties of aversion and the making of electricity produced via friction flashes
friction based electricity is an awkwardness of electric charges inside or on the outside of a material. The charge stays until it can move away through an electric flow or electrical release.
In view of similar kinds of examinations like the one you performed, researchers had the option to set up three laws of electrical charges: Inverse charges pull in one another. Like charges repulse one another. Charged items pull in nonpartisan articles.
Cutting of Nails is a Physical Change since no new substance is formed.
Don't confuse it with Reversible and Irreversible Changes
