Answer:
True
Explanation:
DNA can be extracted from bite marks, cigarette buds, postage stamps on envelopes, and envelope flaps for DNA analysis.
Explanation:
It is the heat required to change a gram of substance from a liquid to a gas.
First, we convert the moles of each substance into the concentration using the volume of the reactor.
[SO₃] = 0.425/1.5 = 0.283 M
[SO₂] = 0.208 / 1.5 = 0.139 M
[O₂] = 0.208/1.5 = 0.139 M
The equilibrium constant is calculated by:
Kc = [SO₃]² / [O₂][SO₂]²
Kc = (0.283)²/(0.139)(0.139)²
Kc = 29.8 = 2.98 x 10¹
The answer is C
Germanium is classified as a metalloid or semi-metal . (:
