it is 12.51 grams cause u just add them together
Answer is C
A synthesis reaction looks like this:
A+ B → AB
The given figure is Lewis structure of BrF₃ and its polarity.
A Lewis structure is based on the concept of the octet rule, in which atoms share electrons so that each atom has eight electrons in its outer shell.
Lewis structures, also known as Lewis-dot diagrams, show the bonding relationship between atoms of a molecule and the lone pairs of electrons in the molecule. Lewis structures can also be useful in predicting molecular geometry in conjuntion with hybrid orbitals.
Net dipole moment of this molecule is not zero. Hence, this is polar molecule.

Answer:
sodium, Na
Explanation:
Na, is the smallest with atomic number 11 and it has one valence electron
Explanation:
As it is given that water level is same as outside which means that theoretically, P = 756.0 torr.
So, using ideal gas equation we will calculate the number of moles as follows.
PV = nRT
or, n =
=
= 0.0052 mol
Also, No. of moles =
0.0052 mol =
mass = 0.0104 g
As some of the water over which the hydrogen gas has been collected is present in the form of water vapor. Therefore, at
= 24 mm Hg
= atm
= 0.03158 atm
Now, P =
= 0.963 atm
Hence, n =
= 0.0056 mol
So, mass of = 0.0056 mol × 2
= 0.01013 g (actual yield)
Therefore, calculate the percentage yield as follows.
Percent yield =
=
= 97.49%
Thus, we can conclude that the percent yield of hydrogen for the given reaction is 97.49%.
