If the temperature of a fish population increases then, the population of fish will increase because the fish like warmer areas to breed and lay eggs.

I'm not sure if this is correct. But always use IF THEN and BECAUSE when writing a hypothesis

Okay well the temperature will only effect some fish since most are smart enough to know to seek deeper water in the cold months. but this also means we humans and many cultures that thrive on them would have to find new ways to catch fish 100's of feet below the waters surface. the way to test this would be to go out and throw a net in different areas of a lake during the summer months when it's hot then in the winter months go back to the same exact areas and throw again and compare data. the hypothesis would be that duringing colder months fish will not be in the shallower waters that are above the goe line in cold weather.hope this helped.<span />

How does mass and volume affect sinking and floating? Please don't plagiarize.... ​
Firdavs [7]

Answer:

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

If the reaction 2HgO --&gt; 2Hg + O2 is endothermic, which bonds are the strongest?
Alika [10]
  • Endothermic reaction means the reactant side takes heat from surrounding and get decomposed i.e ∆H=-ve
  • If the equation is exothermic then it means the reactant is happy to decompose .But it's not as it's endothermic

Now

  • HgO is Omitted from our solution option.

Hg is a atom so no bonds hence no bond strength occurs.

  • O_2 is a molecule and so it's our answer .

What is the value for ∆Soreaction for the following reaction, given the standard entropy values? 2H2S(g) + SO2(g) 3Srhombic(s) +
Mademuasel [1]

Answer: \Delta S^{0} for the reaction is -186.75 J/K

Explanation:

Change in entropy (\Delta S^{0}) for the given reaction under standard condition is given by-

\Delta S^{0}= [3\times S_{rhombic}^{0}_{(s)}]+[2\times S_{H_{2}O}^{0}_{(g)}]-[2\times S_{H_{2}S}^{0}_{(g)}]-[1\times S_{SO_{2}}^{0}_{(g)}]

So \Delta S^{0} = [3\times 31.8 J/K.mol]+[2\times 188.825 J/K.mol]-[2\times 205.79 J/K.mol]-[1\times 248.22 J/K.mol] = -186.75 J/K
