Ca: 40.078 g/mol
C: 12.011 g/mol
O: 16.00g/mol
CaCO3:
molar mass of 100.089g/mol
Answer:
Explanation:
Hello,
In this case, since the percent abundance of Br-79 is 51.1% and that of the Br-81 is 48.9 %, we can write:
Taking into account that the mass of bromine from the periodic table is 79.909 amu, the mass of Br-81 turns out:
Best regards.
Because you need to know what you are looking for before actually trying something so you can prevent any accidents by doing stuff at random
The factor that determine how water cycles on earth is the forms that water is found in[solid, liquid and gas].
Answer: similarities
- there are some cases where the element confer some of its own properties to the compound, so there are properties which are similar between the element and the compound, for example when an element is strongly charged with electrons, the element confer this property to the compound, and this similar between them.
- the other similarity is that both, the compound and element are formed of atoms, electrons and neutrons.
differences
The principal difference is that a element is conformed only by one element but a compound can be conformed for more than two elements.
