Answer:
Trigonal pyramid molecules (three identical bonds)
Explanation:
In trigonal pyramidal molecule like molecule of ammonia , the vector some of intra- molecular dipole moment is not zero because the bonds are not symmetrically oriented . In other molecules , bonds are symmetrically oriented in space so the vector sum of all the internal dipole moment vectors cancel each other to make total dipole moment zero.
I would go with c.an element but if its not that then im really sorry but i tried my best and i hope this helps
The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>
Carbon Reasons: (1) Quicklime is produced by the thermally decomposing limestone, which produces carbon dioxide as a byproduct
<span>CaC<span>o3 --> </span>CaO+C<span>O2
</span></span>
(2) Since this reaction requires a large amount of energy, fuel (usually coal) is burned, which produces carbon dioxide
Answer is B can you like btw??
