Answer: The force of attraction present between the solids depends on the type of solid.
Explanation:
For e.g. if solid is ionic solid, then the ionic forces hold on the solid molecules. And these forces hold together and form solid. When it comes to hydrogen bonding stronger the hydrogen bonding, more together the molecules and it become solid.
Answer:
I believe that we humans will never be able to perfectly predict weather because nature is unpredictable, we face the challenges of when, and where when trying to predict storms, all countries most likely do not posses the resources and funds for these technologies, instead they could get a few meteorologists to study the weather.
Cobalt(II) has a charge of 2+
Phosphate has a charge of 3-
Because it's an ionic compound, you will need to take the charge and make them subscripts.
The formula for cobalt(II) phosphate is
Co₃(PO₄)₂
Your answer is
The thing that two changes have in common that snails growing shells and rust forming on a bicycle frame is option D. Both are caused by cooling.
<h3>How come snails develop shells?</h3>
Calcium carbonate is said to be the material that makes up the shell. The snail's shell expands as it grows to accommodate its growing body. Snails and slugs are also members of the mollusc family of creatures.
Therefore, note that air that has been mixed with the metal can make rust to develop. and as such, option D. Both are caused by cooling. is correct.
