A teaspoon of caffeine is <em>NOT</em> deadly as teaspoon of ricin
Answer:
actually answer should be helium
Well, a compound has a total charge of 0. So, it's electrically neutral. Since the X is 3+ and the Y is 3- they add to 0. Meaning no subscripts are necessary. Why don't you try a different combo?
Like:
A^3 and B^1-, to get a 3- charge you need 3xB^1- so the formula is AB3
Does this help?
Explanation:
Mutations on DNA create genetic variation and diversity on which natural selection acts upon. Mutation can be advantageous, disadvantageous or neutral. Those mutations that confer advantage are preserved in the population while those that are DISadvantageous are weeded out. This occurs because advantageous traits that give a particular advantage to individuals in the environment, however slightest, give them an increased chance of survival and passing their genes to subsequent generations.
An example is mutation that causes sickle cell-shaped blood cells. Individuals with sickle cell blood are less likely to contract malaria. Therefore in an environment where malaria is endemic, the population will have a higher allele frequency for sickle cell alleles that populations in non-endemic areas.

Answer:
1.25 Moles
Explanation:
1.25 moles of solute
Explanation:
Molarity is defined as the number of moles of solute per liter of solution.
Molarity = moles of solute / liter of solution
We are given the molarity and volume, both of which have the correct units. All we have to do is rearrange the equation to find the number of moles. You can do this by multiplying both sides of the equation by the volume to cancel it out on the right hand side. Afterwards, you should end up having the volume multiplied by the molarity equaling the number of moles of solute like so:
Moles of solute = Molarity * Volume
2.5M HCl * 0.5 L = 1.25 moles of HCl
I hope this made sense.
