Answer:
True.
Explanation:
Yes, analyses of enzymes found in the blood are used as indicators of tissue damage in the heart, liver, muscle etc has occurred. This leakage of enzymes into the bloodstream tells us whether the tissue is damaged or not. Lactate dehydrogenase is a type of enzyme which is used as indicator which is responsible for the interconverts lactate and pyruvate. The concentration of this enzyme in the blood tells us about tissue damage.
<span>A student records the mass of a piece of iron. The iron is then left outside until it rusts. The type of reaction that occurs is oxidation reaction. The mass of the object decreases after rusting compared with its original mass.</span>
Yo sup??
Heat produced per gram of reactant=13.1 KJ
.=13100 J
Actual heart produced=1850 J
By applying unitary method we get the weight of reactant to be x
x=1850/13100
=0.141 gm
Hope this helps
Sn2+
Your protons equal the atomic number of an element: Sn (Tin).
The amount of protons and electrons will be the same if the atom is neutral. In this case, tin has lost two electrons and so tin is no longer neutral and becomes Sn2+
To double check, you would subtract the atomic number from the mass number of tin to see if the number of neutrons is equal to what has been provided.
mass number - atomic number = number of neutrons
118 - 50 = 68
