They do this in order to survive their new environment. If they didn't adapt, then they would die!
The heat released : -110560.632 J
<h3>Further explanation</h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
<h3>Known</h3>
m =465 g
c water = 4.186 J/gram °C
∆T = temperature difference = 18.2 - 75 = - 56.8 °C
Then the heat :

It's b. calcium
because the outer electron structure in all of that element is similar, they have the same chemical and physical properties.<span />
<span>Answer:
The two basic steps to determine whether a molecule is polar are:
</span>
<span><span>1) determine whether the molecule contains polar bonds?
</span>
2) determine whether the polar bonds add together to
form a net dipole moment.
Explanation:
The fundamental requirement is that there are polar bonds. Polar bonds are covalent bods with dipole moments. Dipole moments are the result of two atoms of different electronegativity sharing electrons. The more electroneative atom pulls the electrons with more strength than the other atom which is what generate the dipole moment.
If the molecule is symmetrical, and the dipole moments are place symmetrically they wil cancel each other and the molecule will not be polar. For example, the molecule of CCl4 has four C - Cl bonds each with dipole moment, but they are loacates symmetrically around the C atom, so they will cancel each other resulting in a zero net sum of dipole moments, being the molecule non-polar.
