C is correct. Have a good day!
Reactivity of non-metals depend on their ability to gain electrons. So, smaller is the size of a non-metal more readily it will attract electrons because then nucleus will be more closer to valence shell. ... Hence, Br is the non-metal which will be more reactive than At.
Answer:
1.atomic number
2.electron
3.element
4.atom
5.neutron
6.nucleus
7.proton

Lithium sulfate is Li2SO4
Strontium chlorate is Sr(ClO3)2
Strontium sulfate is SrSO4
So the complete balanced chemical reaction for this is:
Li2SO4 (aq) + Sr(ClO3)2
(aq) --> SrSO4 (s) + 2 LiClO3
(aq)
This is a type of double replacement reaction since there
is an exchange of ions.
Answer:
2.29 g of N2
Explanation:
We have to start with the <u>chemical reaction</u>:

The next step is to <u>balance the reaction</u>:

We can continue with the <u>mol calculation</u> using the molar mass of
(65 g/mol), so:

Now, with the<u> molar ratio</u> between
and
we can <u>calculate the moles</u> of
(2:3), so:
With the molar mass of
we can <u>calculate the grams</u>:
