Idk you didn't be very specific
Nucleus:direct all the organelles
Answer:
Q = 3.21 kJ
Explanation:
First, with the heat of hydration and the lattice energy, we can actually calculate the difference between those two to get the heat evolved per mole. In this case it would be:
657 - 639 = 18 kJ/mol
Now, the expression to get the heat is:
Q = m*ΔE
We already have the energy, now we need to get the moles of the cesium chloride.
The molar mass of cesium chloride is 168.36 g/mol, so the moles:
mole = 30/168.36 = 0.1781 moles
Finally the heat:
Q = 0.1781 * 18
Q = 3.21 kJ
Answer: The rock formed from cooling lava.
Explanation:Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.
