Answer:
1
Explanation:
one possible way its just a theory of what the answer could be
I do not have my reference table out to see the periodic table but in order to achieve the answer pull out the periodic table. You now know that this element is going to be a metal because it is a good conductor of electric and is malleable. Next you will find both cesium and radon and look in between them to see which one is a metal that has an atomic number that lies between both radon and cesium
Answer:
a free swimming larval stage in which a parasitic fluke passes from an intermediate host to another intermediate host
Answer:
Explanation:
Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations. Only the species which are present in aqueous state dissociate. So, the net ionic equation of aqueous solution of ammonia is shown below as:-
Answer:
2.74 percent hydrogen and 97.3 percent chlorine are in 2 g of compound.
The same as initial
Explanation:
HCl → H⁺ + Cl⁻
2.74% H means that in 100 g of compund, 2.74 grams are H
97.3 % Cl means that in 100 g of compound, 97.3 grams are Cl
So how many grams of H and Cl, are in 1 g of compound
100 g ___ 2.74 g are H _____ 97.3 g are Cl
1g _____ 2.74/100 ____ 97.3/100
0.0274 g are H
0.973 g are Cl
In 2 grams we will find
0.0274 g .2 = 0.0548 g of H
0.973 g .2 = 1.946 g of Cl
(grams / total grams) . 100 = %
(0.0548/2 ) .100 = 2.74%
(1.946 /2) .100 = 97.3%
