Answer: The correct answer is a) Acetylcholine.
Explanation:
The acetylcholine is a very important neurotransmitter involved in the mediation of synaptic activity between neurons. Among its most important functions we find: expression of mood states, vasodilation, gastrointestinal motility, bronchoconstriction, circular iris muscle contraction and sweat gland secretion.
Therefore the correct answer is a) Acetylcholine.
sodium cloride is salt created from sodium Na and chlorine Ci
Na-sodium Ca- calcium
Ci-chlorine FL- flerovium
Ca- calcium Br-bromine
H- hydrogen He-helium
Answer:
mass of carbon-dioxide = 0.262 g
Explanation:
Firstly, write the chemical equation of the reaction and balance the equation accordingly.
2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)
Calculate the molecular mass of baking soda
molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g
2 moles of baking soda = 2 × 84 = 168 g
molar mass of CO2 = 12 + 32 = 44 g
if 168 g of baking soda produces 44 g of carbon-dioxide
1 g of baking soda will produce ? grams of carbon-dioxide
cross multiply
mass of carbon-dioxide = 44/168
mass of carbon-dioxide = 0.2619047619
mass of carbon-dioxide = 0.262 g
