Answer:
The basicity of HCOOH (otherwise known as formic acid) is 1
Explanation:
Answer: 35.4 g
2 moles of phosphorous chloride are produced by = 3 moles of
Thus 0.37 moles of phosphorous chloride are produced by= of
Mass of
Thus 35.4 g of chlorine reacted with the phosphorus
Answer:
Explanation:
Hello!
In this case, when writing net ionic equations, we first need to identify the complete molecular equation; thus for potassium dichromate reacting with copper (I) bromide, we have:
Thus, since all the species are aqueous except copper (II) dichromate, we can write the complete ionic equation by ionizing the aqueous ones:
Finally, for the net ionic equation, we need to cancel out the spectator ions as they are present at both reactants and products sides, thus, we obtain:
Best regards!
We are diploid organisms thus require two sets of chromosomes. In order to ensure the zygote is a diploid (has 2 sets of chromosomes) the gametes must be haploids (has 1 set of chromosomes) as two gametes join to make a zygote.
Having half the set of chromosomes also ensures that the offspring receives half of its chromosomes from its father and half from its mother. This becomes very important as to ensure there is genetic diversity in the offspring, both the fathers and mothers genes are needed.
