The gas is NH₃.
H₂ doesn't dissolve readily in water, SO₂ gives an acidic solution in water.
The solid residue is Fe(OH)₂.
FeSO₄ and Na₂SO₄ are soluble in water.
The answer is C.
I think the best answer that will describe chemical change is the first option. During a chemical change, b<span>oth the identity and the properties of a substance change because new substances are being formed by a chemical reaction. An example is rusting of steel</span>
It's a surface current because it's driven by the winds near the equator.
Explanation:
The Gulf stream<span> System is </span>one of<span> the world's most intensely studied current systems. The </span>Gulf stream<span> begins upstream of </span>the promontory<span>, </span>wherever<span> the </span>Sunshine State<span> Current ceases to follow the </span>seabed<span>. The position of the Stream </span>because it<span> leaves the coast changes throughout the year. </span>within the<span> fall, it shifts north, </span>whereas within the<span> winter and early spring it shifts south.</span>
Answer:
and 
Explanation:
The equation for the reaction is AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq)
With all the ions, it is
(aq) + 
(aq) + (aq) + 
(aq) ==> AgCl(s) +
and do not change, so they are the spectator ions and are removed
The ionic equation is:
(aq) + (aq) ==> AgCl(s)
