The 32.06 represent The atomic mass, the average number of protons & neutrons
<h3>Further explanation
</h3>
The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.
So atomic number = number of protons = number of electrons
Mass Number (A) is the sum of protons and neutrons
Mass Number (A) = Number of protons + Number of Neutrons
So that the relationship between atomic numbers and mass numbers can be formulated as follows:
Atomic Number (Z) = Mass Number (A) - Number of Neutrons
In the following element notation,
X = symbol of elemental atom
A = mass number
= number of protons + number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
No, because humans are much more complex than peas.
Answer:
b) +2 and +3.
Explanation:
Hello,
In this case, given the molecular formulas:
And:
We can relate the subscripts with the oxidation states by knowing that they are crossed when the compound is formed, for that reason, we notice that oxygen oxidation state should be -2 for both cases and the oxidation state of X in the first formula must be +2 since both X and O has one as their subscript as they were simplified:
Moreover, for the second case the oxidation state of X should be +3 in order to obtain 3 as the subscript of oxygen:
Thus, answer is b)+2 and +3
Best regards.
Answer : The mass of the water in two significant figures is,
Explanation :
In this case the heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron metal =
= specific heat of water =
= mass of iron metal = 32.3 g
= mass of water = ?
= final temperature of mixture =
= initial temperature of iron metal =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the mass of the water in two significant figures is,
