Answer:

The stars when they release their helium and get rid of their cape and throw it into space is because it is already the end of their life

Explanation:

During a portion of its life, a bright star due to the thermonuclear fusion of hydrogen in helium in its nucleus, which releases energy that crosses the interior of the star and then radiates into outer space. When the hydrogen in the nucleus of a star is almost depleted, almost all heavier elements than naturally produced helium are created by stellar nucleosynthesis during the life of the star and, in some stars, by nucleosynthesis of supernovae when explode At the end of its life, a star can also contain degenerate matter

Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not react the same chemi

wariber [46]

Monosaccharides are the simplest carbohydrates. Although glucose and fructose have the same molecular formula they have different structures or the atoms are arranged differently from each other and this is evident in the way they react, behave and in their properties.

For the reaction below , label each reactant as an electron pair acceptor or electron pair donor and as a Lewis acid or a Lewis

JulsSmile [24]

Since the reaction shown in the question is an acid - base reaction in the Lewis sense; the Lewis acid here is AlCl3 while the Lewis base here is Cl^- .

<h3>What is a Lewis acid?</h3>

A Lewis acid is a substance that accepts electron pair while a Lewis base donates an electron pair.

Now consider the given reaction; AlCl3 +Cl^- ------> AlCl 4 ^-. The Lewis acid here is AlCl3 while the Lewis base here is Cl^- .
