Answer:
Gas cloud 1: It spreads with a greater volume and less concentration of elements. Its temperature stays well below the 14 million Kelvin. It has hydrogen atoms that retain there electrons.
Gas cloud 2: Its volume shrinks and the density increase die to the gravity
. Its temperature stays above the 14 million kelvin
. Hydrogen atoms shed there electron.
Explanation:
As you already know, stars form within clouds of gas. These clouds have interstellar gases composed mainly of dust and hydrogen. When subjected to low temperatures, gases react and combine to form molecules that create clouds and continue to react until they form stars.
Cloud 1 has characteristics that show that it will form a star which are: It spreads with a greater volume and less concentration of elements, its temperature stays well below the 14 million Kelvin, it has hydrogen atoms that retain there electrons.
as we know that cloud 2 will not form stars we can say that its characteristics are: Its volume shrinks and the density increase die to the gravity
, its temperature stays above the 14 million kelvin
, hydrogen atoms shed there electron.
Answer and Explanation:
An acid has a pH that is less than 7. A base has a pH that is greater than 7. Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1: Base
Situation 2: Acid
Situation 3: Acid
Situation 4: Base
Situation 5: Acid
Situation 6: Base
A. Water directly out of the tap has a pH of 7.2. When you add carbon dioxide (blow into the water), you get a pH of 5.1. This means that the addition of carbon dioxide makes water more acidic.
B. The most basic solution will have the highest pH. This means that it will be water with bleach added to it.
C. The most acidic solution will have the lowest pH. This means that it will be water with instant coffee.
Answer:
Alkenes, A hydrocarbon with at least one carbon–carbon double bond that is unsaturated. An unsaturated hydrocarbon with at least one carbon—carbon triple bond between two carbon atoms is known as an alkyne.

Explanation:
Embryonic stem cells are plentiful, and they can create every cell in the human body. Researchers can use these cells to create tissues. They can possibly grow new organs in a lab to treat diseased organs. Adult stem cells are rarer in the human body, and they’re limited in the types of cells they can make.
An embryo can’t grow without its stem cells, so people have ethical concerns about their use. Adults can provide consent to donate their stem cells, so there are fewer ethical issues regarding the use of adult stem cells.
DNA, nucleosome, coils, supercoils, chromosome.
