Answer:
One can determine the specific heat of the metal through using the clarimeter, water, thermometer and using heat equations.
Explanation:
You can learn about heat effects and calorimetery through a simple experiment by boiling water and heating up the metal in it. Then, pour it into your calorimeter and the heat will flow from the metal to the water. The two equlibria will meet: the metal will loose heat into its surroundings (the water) and teh water will absorb the heat. The heat flow for the water is the same as it is for the metal, the only difference being is the negative sign indicating the loss of the heat of the metal.
In terms of theromdynamics, we can deteremine the heat flow for the metal becasue it would be equal to the mangnitued but opposite in direction. Thus, we can say that the specific heat of water qH2O = -qmetal.
Electronegativity is a measure of the ability of an atom to attract electrons. The value tends to increase on moving from left to right across a period in the periodic table. This is because as the atomic number increases so does the nuclear charge which causes the added electron to experience a stronger nuclear attraction.
For example, if the consider the second period, then Lithium which is present in the extreme left will show a greater tendency to lose electrons (lower electronegativity) while Fluorine present in the extreme right will show a greater tendency to attract electrons and therefore high electronegativity. Thus, when Li and F combine, they form what is called an ionic bond.
Ans C) True statement
When the element is reduced it gains electrons, maybe it's charge becomes more negative.
Answer: It is important because the object must go through heat to be melted and then it should be put into a mold to be formed.
Explanation:
5 is d because methane is a greenhouse gas
6 is a because it is a cause for global warming
