Answer:
Florida's Global Pattern.
Explanation:
Because of where Florida sits, the weather in the Gulf of Mexico actually blows enough water to Create tidal waves, and also hurricanes. at least that's what I was told cause I live here :>
Answer: 165.6grams
Explanation:
Mass of a block = ?
Volume of block = 18 cm^3
Density of block = 9.2 g/cm^3
The density of any object depends on its mass and volume.
i.e Density of block = Mass / volume
9.2 g/cm^3 = Mass / 18 cm^3
Mass = 9.2 g/cm^3 x 18 cm^3
= 165.6 g
Thus, the mass of the block is 165.6grams
Explanation:
Here I send you all the 3 elements that you are asking for.
Notice that first on the left you will find lewis structure, then condensed and finally chemical formula of each of the compound you enlisted.
For this reaction to proceed, the following bond breaking should occur:
*one C-H bond
* one Cl-Cl bond
After, the following bond formations should occur:
*one C-Cl bond
*one H-Cl bond
Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.
ΔHrxn = (1)(413) + (1)(242) + 1(-328) + 1(-431) =
<em>-104 kJ</em>
