Answer:
4 C2H5 + 13 O2 -> 8 CO2 + 10 H2O
Explanation:
What I do is I make a chart of how many elements the product side and reactant sides have:
Reactants-
2 C
5 H
2 O
Products-
1 C
3 O
2 H
It's easier to see how many coefficients are needed for the reaction to be balanced then. Hope this helped.
Answer:
2-0-1, 1-1-1, 0-1-2, but they must all equal 3 electrons in total
Explanation:
Answer:
trigonal pyramidal
Explanation:
In NF3, the nitrogen atom is sp3 hybridized. Now we must remember that according to the VSEPR theory, the number of electron pairs in the valence shell of the central atom in a molecule determines its shape.
Here, the nitrogen atom is the central atom and its outermost shell is surrounded by four electron pairs - one lone pair and three bond pairs. This means that it has a tetrahedral electron pair geometry.
However, due to the lone pair, the three fluorine atoms are arranged in a trigonal pyramidal geometry. Hence the correct shape of the molecule is trigonal pyramidal.
Answer:
work can be the operation or function of something but it can also be the energy transfer that occurs when an object is moved or in everyday life it means to do something (specific thing). I don't know all of them by the way.
Explanation:
the differences in meaning sometimes makes it easier and sometimes makes it harder to learn science and technology. sometimes the everyday meaning might somehow be related to the science meaning which helps you grasp everything better while sometimes the meaning is so far fetched it makes it harder to know what you are learning. hope this helps
