Hello!
In this case, for this acid-base reaction which also known as a neutralization because sulfuric acid is neutralized with sodium hydroxide, we can write the undergoing chemical reaction as shown below:
However, it needs to be balanced as two sodium atoms are yielded:
Next, since there is a 1:2 mole ratio between the acid and the base, at the equivalence point, at which the moles of acid and base are consumed, we write:
Which can also be written in terms of the given volumes and concentration of the base:
In such a way, we solve for the concentration of sulfuric acid as shown below:
Best regards!
We must first convert the weight in grams to milligrams and hectograms to find the right answer. 5.63 grams 0.0563 hectograms
5.63 grams=5,630 milligrams
So it's 5,630
Explanation:
it contains 6.02*1023atoms

Answer:
A tick living on a dog and drinking it's blood = Parasitism
Birds that live among cattle too eat insects stirred up by grazing = Mutualism
A clownfish living on the tentacles of an anemone provides nutrients too the anemone, and the clownfish is protected from predators = commensalism
A bear catching and eating a salmon from the river = predation
A bobcat catching and eating a rabbit = predation
A tapeworm living on the digestion system of a horse = parasitism
A Egyptian plover eating bugs off a giraffe or rhino = Mutualism
Bees gathering nectar and then spreading pollen too a flower = commensalism
