Answer:
4,270 Joules
Explanation:
The heat of fusion of water is 334 j/g. So, the equation would be (12.8 g)(334 j/g) which comes to 4,270 joules.
Written out that's just twelve point eight times three hundred and thirty four.
Plants have made a variety of reproductive adaptations to ensure the spreading and survival of their seed. A common example is the bright colors of many flowers. The purpose of this adaptation is to draw specific insects and birds that will visit the plant and distribute its pollen when they move on to the next plant.
Structural adaptations allow plants to live in specific environments, as is seen in the stark contrast between the roots of terrestrial plants, which are firmly rooted in the ground, and plants that float on the surface of bodies of water.
An example of a behavioral adaptation in plants is how certain desert plants have developed opportunistic behaviors that allow them to spring from dormancy to sudden reproductive activity during times of moisture and cool temperatures.

<u>Answer:</u> The value of <em>i</em> is 1.4 and 40% dissociation of 100 particles of zinc sulfate will yield 60 undissociated particles.
<u>Explanation:</u>
The equation used to calculate the Vant' Hoff factor in dissociation follows:
where,
= degree of dissociation = 40% = 0.40
i = Vant' Hoff factor
n = number of ions dissociated = 2
Putting values in above equation, we get:
The equation used to calculate the degee of dissociation follows:
Total number of particles taken = 100
Degree of dissociation = 40% = 0.40
Putting values in above equation, we get:
This means that 40 particles are dissociated and 60 particles remain undissociated in the solution.
Hence, 40% dissociation of 100 particles of zinc sulfate will yield 60 undissociated particles.
