Answer:
Use the vingear and baking soda experiment but change it to lemon and not vingear.
Explanation:
A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less
The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
Answer:
Jimmy's blood type: "O" Blood
Jimmy can receive blood from: O blood type only.
Explanation:
The anti-A antibodies are present in the plasma of "B" blood type. Similarly, the blood type "A" has anti-B antibodies in its plasma. Since Jimmy's blood is showing agglutination with both "A" and "B" blood type, he has "O" blood type.
The "O" blood type has both anti-A and anti-B antibodies in its plasma and exhibits agglutination with both A and B blood type. The "A" antigen of "A" blood type reacts with anti A antibodies of jimmy's blood while "B" antigen of "B" blood type would exhibit agglutination with "anti B antibodies" of Jimmy's blood. He can get blood from "O" blood type only as he has both anti-A and anti B antibodies in his blood plasma.
Answer:
Deuterium, (D, or 2H), also called heavy hydrogen, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). Deuterium has an atomic weight of 2.014
