In order to solve this, we need to make use of Hess' Law.
We are already given the equations and their corresponding deltaH. Using Hess' Law, we can generate this equation:
104 kJ = x - (-1182 kJ) - (-1144 kJ)
Among the choices, the answer is
<span>B.104 = x - [(-1182) + (-1144)]
</span>
The molecule<span> is symmetric, a tetrahedron. Thus, the 4 </span>polar bonds <span>cancel each other out.</span>
<span>To compare the energy of microwaves, IR-B, and IR-A, we need to compare how long the wavelengths are for each wave. Through the intervals given, we can determine that we in order from greatest to least energy, the order is IR-A, IR-B, microwaves.</span>
Answer:
answer
<u>Cold Front - a zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer. </u>
<u>Warm Front - a transition zone between a mass of warm air and the cold air it is replacing. </u>
<u>Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.</u>
I love chem!!! Hopefully I got it right for u I got
In the calculator: 7.127272727
But if u need it in sig figs: 7.1atm
