I had this question on a test the answer is an exothermic reaction.
<span>n = 5 shell=50</span>
<span>n = 2 shell=8</span>
<span>n = 2, l = 0 subshell=2</span>
<span>n = 2, l = 1 subshell=6</span>
<span><span>3d subshell=</span>10</span>
<span>2s subshell=2</span>
<span><span>5f subshell=14</span></span><span><span> sorry if I'm late I just did this! hope it helps..</span></span>
Answer:
C
Explanation:
Since they all are 2 mols worth, all you have to do is count the number of atoms in each molecule
H2SO4 contains 2 hydrogen 1 sulfur 4 oxygen = 7 atoms
H2S contains 2 hydrogen and 1 sulfur = 3 atoms
H3PO4 contains 3 hydrogens 1 phosphorus 4 oxygens = 8 atoms
HNO3 contains 1 hydrogen 1 nitrogen and 3 oxygens = 5 atoms
You have the right answer.
Answer:
Carbon
Explanation:
The way to identify an element is by looking at the number of protons the atom has. Every element has its own atomic number. This atom has 6 protons. If you look at the periodic table, you can see that the atom with the atomic number of 6 is carbon.
