Answer:
Always carry the microscope with two hands. One on the arm and one underneath the base of the microscope.
The general term that we could label to the description is a mixture. A mixture is composed of different pure substances. If we want to be specific, we could classify it as homogeneous or heterogeneous mixture. Since the ingredients are not all soluble with each other, this is a <em>heterogeneous mixture</em>.
Answer: I believe the Answer is A
Answer:
Tritium
Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron. It is radioactive, with a half-life of 12.32 years.
Explanation:
hope it helps :)))
Molecular formula=C3H6
Explanation
As with all of these problems, we assume 100 * g of unknown compound. And this, we determine the elemental composition by the given percentages.
Miles of carbon= 85.64*g/12.011*g*mol-1=14.25*mol
Clearly there are 3 mols of hydrogen per mol of carbon. And thus the empirical formula is CH2.
And molecular formula=n*(12.011+2*1.00794)*g*mol-1
And this n=3, and molecular formula=C3H6.
