<span>metallic elements are malleable because of its ability for the atoms to roll on top of one another without breaking its metallic bond (This is because it is attracted with more force, and is the reason why they have higher melting/boiling points); however, a nonmetals form molecular bonds which doesn't have this property</span>
Answer:
Below.
Explanation:
The balanced equation is:
Ba(CN)2 + H2SO4 ---> 2H(CN) + BaSO4

Answer:
Increasing the concentration of A will cause the greatest change over the rate.
Explanation:
Hello,
In this case, considering the given rate law, which is third-order with respect to A, changing its concentration, the rate will be significantly modified. For instance, suppose a concentration of A and B of 1M and a symbolic rate constant (k), this causes the rate to be:
Then, if we change the concentration of A to 2 M holding the concentration of B in 1 M, the new rate constant will be:
Nevertheless, if we hold the concentration of A in 1 M and the concentration of B is now 2 M (same change), the new rate constant is:
It means that increasing the concentration of A will cause the greatest change over the rate.
Best regards.
First step is to get the mass of water molecule in grams:
From the periodic table:
molar mass of hydrogen is 1
molar mass of oxygen is 16
molar mass of a water molecule = 2(1) + 16 = 18 gm
Now, to convert the gm into amu, all you have to do is multiply the gm you got by Avogadro's number as follows:
mass of water molecule = 18 x 6.22 x 10^23 = 1.1196 x 10^25 amu which is approximately 1 x 10^25 amu
