Answer:
equation 1: AgNo3 + Zn is the reaction because of the zinc
Answer:
a. 2954g of FeS
b. 1143g of FeS
Explanation:
Based on the reaction:
8 Fe + S₈ → 8 FeS
<em>8 moles of Fe reacts with 1 mole of S₈ to produce 8 moles of FeS</em>
<em />
a. 4.2mol sulfur produce:
4.2mol S₈ × ( 8 mol FeS / 1 mol S₈) = <em>33.6mol FeS</em>. As molar mass of FeS is 87.92g/mol, mass is:
33.6mol FeS × ( 87.92g / 1 mol FeS) = <em>2954g of FeS</em>
<em />
b. 13mol Fe produce:
13mol Fe × ( 8 mol FeS / 8 mol Fe) = <em>13mol FeS</em>. In mass:
13 mol FeS × ( 87.92g / 1 mol FeS) = <em>1143g of FeS</em>
<span>The only statement that states a fact about metals is the first option, letter A. They are shiny and bend without breaking. Choices B-D are wrong because metals are not insulators but are god conductors of heat and electricity. Metals can be flattened but they are not brittle.</span>
Answer:
They are eukaryotic, which means they have a nucleus. Most have mitochondria
