pantera1 [17]

Answer:

B:  Fission reactors generate huge amounts of heat.

C:  Fission breaks down unstable elements such as uranium in a breeder                         reactor which is broken down in the process of fusion which is literally breaking down of elements.

E: fission is used in nuclear weapons as it is easier to accomplish then fusion  bombs

Explanation:

A: as a zero-waste energy source

B: for generating large amounts of heat

C: for creating stable elements from unstable ones

D: for creating new, heavier elements

E: as the energy source in nuclear weapons

Based on Reference Table S, the atoms of which of these elements have the strongest attraction for electrons in a chemical bond?
BabaBlast [244]
Answer is (1) - N

<em>Explanation:</em>

I think the given chart is electronegativity chart.

Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is high, then the attraction to the electrons is high unless the attraction to the electrons is low. </u>

Electronegativity increases from left to right of the periodic table and decreases from up to down. 
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).

The electronegativity values for given atoms are
  N - 3.0
  Na - 0.9
  P - 2.1
  Pt - 2.2 </span>

An aqueous solution of methanol (MM = 32.04 g/mol) has a molality of 8.83 m and a density of 1.15 g/mL. What is the molarity of
hodyreva [135]

We have that the  the molarity of methanol in the solution is mathematically given as

Morality=7.91mol/l

<h3>Chemical Reaction</h3>

Question Parameters:

An <u>aqueous </u><em>solution </em>of methanol (MM = 32.04 g/mol)

A molality of 8.83 m and a density of 1.15 g/mL.

Generally the equation for the   is mathematically given as

Morality=\frac{moles of solute }{mass of the solvent}

where

Mass of solution=(100+282.2)

Mass of solution=1289.9

Volume=1289.9/1.15

Volume=1.115L

Therefore

Morality=\frac{moles of solute }{mass of the solvent}

Morality=8.83/1.115

Morality=7.91mol/l
