B. False

Answers

True

Explanation:

The statement that patience, a popular card game in Mendeleev's time is also know as solitaire is very true. It was this card game that led to the discovery of the periodic table by Mendeleev in the 19th century.

In Europe, the game is called Patience. It is commonly called solitaire in in North America.
It involves the arrangement of a deck of cards.
The game inspired the invention of the periodic arrangement of elements by Russian Chemist, Dmitri Mendeleev.
Solitaire was popular card game around the time of this discovery.

A water molecule gains enough energy to enter the gas phase is chemical or physical?why?

Answers

Physical because you are not changing the substance. For example water vapor(gas) can be condensed back into water. If you burn a piece of paper the ash cannot be changed back into paper therefore it is chemical. But because you are not changing the substance the answer is physical.

It is a physical change becasue the chemical makeup of the water molecule did not change - the molecule just changed state.

Which statement best describes what happens in a fission reaction

Answers

The answer is; Heavy nuclei split into lighter nuclei

Heavier isotopes of elements are the most unstable and decay quickly into lighter elements (mostly because they have high neutron to proton ratio). The decay involves the splitting of the heavier atom into a lighter atom and the release of neutron(s) particles and radiation energy. The released neutrons then hit another isotope and split it. This chain of reaction continues so far as the isotopes are close by. The time it takes for a radioactive element to decay into another element is called half-life.
