Endothermic is a chemical reaction which absorbs energy in the form of heat
Answer:
Length = 681 grams / (44.5 grams / kilometers) = (681 / 44.5) kilometers
Explanation:
The diameter is there to throw us off, so ignore that. There is 681 grams of wire, and since there is 44.5 grams of copper <em>per</em> km of wire, and we want to know how many kilometers of wire makes 681 grams, the equation would be X*44.5 = 681, or X = 681/44.5
Also quora's censoring system is terrible i can't even say kilometers by adding the letter s after "km"
In order to identify the reducing agent let us check the oxidation states
I2 + Ti+4 ----> Ti + IO3- reducing agent
I2 : oxidation state of I = 0
Ti^+4 = oxidation state of Ti = +4
Ti : oxidation state = 0
IO3^-1 , oxidation state of Iodine = +5
So here the Ti undergoes reduction hence it is oxidizing agent
Where iodine undergoes oxidation hence it is reducing agent
The answer is; C
Due to the intense heat and pressure on the rocks, they undergo physical and chemical changes and become new types of rocks called metamorphic rocks. An example of this change is that small crystals may be squeezed into large crystals and the crystals may be rearranged.
