Answer: B
. particle size
Explanation:
Let's begin by explaining that a molecular sieve is a device, whose composition allows the absorbtion of molecules that are small enough to pass through its pores, since it is made up of small pores of a precise and uniform size.
Thus, very small molecules manage to pass through the pores of the sieve, while large ones do not.
So, based on this premise, a molecular sieve separates the substances by their size.
Hence, the correct option is B.
Answer:
53.6 grams of silver chloride was produced.
Explanation:
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
Mass of silver nitrate = 50.0 g
Mass of hydrogen chloride = 50.0 g
Mass of silver chloride = x
Mass of nitric acid = 46.4 g
Mass of silver nitrate + Mass of hydrogen chloride =
Mass of silver chloride + Mass of nitric acid
[te]50.0 g+50.0 g=x+46.4 g[/tex]
53.6 grams of silver chloride was produced.
Answer:
Explanation:
Decomposition is the answer.
If a compound breaks into two or more parts then it is called decomposition.
Answer : Hg (Mercury)
Explanation : In the given series of elements Na falls after the Cu in the reactivity series, for Pb it also falls after Cu, and for Mg it is the same.
Only Hg which is mercury can spontaneously donate its electrons to copper in the solution because it falls before Cu in the reactivity/activity series.
Answer: 5.43x10^23 g/mole M&M's
Explanation:
1 bag of M&M's = 1.75oz (1.75oz)*(453.6g/16oz) = 49.61 g
1 bag = 55 M&M's
(49.61 g)/55 M&M = 0.9021 g/MM
1 mole M&M's = 6.023x10^23 M&M's
(6.023x10^23 M&M's)*(0.9021 g/MM's) = 5.43x10^23 g/mole molar mass
