Answer:
1 mole =22.4 L of gas at STP. So now 1 mole of H2 gas weighs equal to 2 grams.
Explanation:
<span>In ionic equations, the chemicals are written as the ions which are dissolved in water.
AgNO</span>₃<span>(aq) reacts with K</span>₂<span>SO</span>₄<span>(aq) and produces Ag</span>₂<span>SO</span>₄<span>(s) and KNO</span>₃<span>(aq). The balanced
complete ionic reaction is
2Ag</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq) +2K</span>⁺<span>(aq) + SO</span>₄²⁻<span>(aq) → Ag</span>₂<span>SO</span>₄<span>(s) +2K</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq)
K</span>⁺<span>(aq) and NO</span>₃⁻<span>(aq) present in both sides. Hence, we can cut off them to find net ionic equation.
So, net ionic equation is
2Ag⁺(aq) + SO₄</span>²⁻<span>(aq) → Ag₂SO₄(s)</span>
False I think because they don't use balloons to check the weather
True.
Sulfur is in the same column of the periodic table as oxygen, but has electronegativity similar to carbon. ... Hydrogen Bonds (The polarity of a water molecule allows the oxygen of one water molecule to bond weakly to the hydrogen of another water molecule.)
