Explanation:
I am not for sure, but i think it explodes :)
C. Protons, neutrons, electrons
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
First equation: A. Combustion
Second equation: C. Decomposition
Third equation: E. Double Replacement
Fourth equation: D. Single Replacement
Fifth equation: B. Synthesis
We place a burning splint at the mouth of the test tube and listen for a pop sound. It occurs because Hydrogen gas is explosive. The third option is correct.
<h2>Halogens.</h2>
Explanation:
All of the halogens form salts with alkali metals with the formula MX.
Halogens are the members of group 17 in the periodic table. They have seven electron in their valence shell and tend to form negative ion with minus one charge. They get there name because of their property to form salts. Halogens are very reactive and form salts with the metals.
