Answer:
3.78x10^23 moles and 17.04 grams
Explanation:
N/A
Barium :

with +2 being the charge
Oxygen :

with -2 being the charge
The given equation can be written as:
Ba + O = BaO
Since the sum charges of Barium and Oxygen equals 0, there is no need to add subscripts.
Both Ba and O appear on the left and right side of the equation once, so there is no need to add a coefficient.
Ba + O = BaO is balanced

Merkel receptor – disk shaped, close to surface, slow adapting, small
receptive field, respond best to PRESSURE and TEXTURE.
(2) Meissner corpuscle – stack of flattened cells with nerve fiber
weaving through, close to surface, rapidly adapting, small reception
force, respond best to LIGHT TOUCH, such as tapping or fluttering.
(3) Ruffini cylinder – many branched fibers in cigar shaped capsule,
deep in dermis, slow adapting, large reception force, respond best to
STRETCHING and play important role in kinesthetic sense.
(4) Pacinian corpuscle – layered, onion-like, deep in dermis, fast
adapting, large reception force, respond best to DEEP PRESSURE touch and
high frequency VIBRATION.
