Answer is: <span>the molarity of this glucose solution is 0.278 M.
m</span>(C₆H₁₂O₆<span>) = 5.10 g.
n</span>(C₆H₁₂O₆) = m(C₆H₁₂O₆) ÷ M(C₆H₁₂O₆<span>) .
</span>n(C₆H₁₂O₆) = 5.10 g ÷ 180.156 g/mol.
n(C₆H₁₂O₆<span>) = 0.028 mol.
</span>V(solution) = 100.5 mL ÷ 1000 mL/L.
V(solution) = 0.1005 L.
c(C₆H₁₂O₆) = n(C₆H₁₂O₆) ÷ V(solution).
c(C₆H₁₂O₆) = 0.028 mol ÷ 0.1005 L.
c(C₆H₁₂O₆<span>) = 0.278 mol/L.</span>
Answer: four hundred and 18
Explanation:
Simple math showed that only 16 words are possible from a two-letter combination, but a three-letter code produces 64 words. Operating on the principle that the simplest solution is often correct, researchers assumed a three-letter code called a codon.
The type of reaction that occurs in the core of a nuclear reactor in a power plant is the fission reaction where the nucleus of an atom is split into smaller nucleus. Along with this splitting, high amounts of energy is being produced. This energy is used to supply power to people.
When the barometer rises it means air pressure goes up. When that happens there is clear skies and little clouds. So you would be expecting hotter weather.
Answer:
2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃
Explanation:
Hydrobromic acid (HBr), reacts with lead (II) nitrate (Pb(NO₃)₂) producing Lead(II) bromide (PbBr₂) and nitric acid (HNO₃). The reaction is:
HBr + Pb(NO₃)₂ → PbBr₂ + HNO₃
This reaction is unbalanced. You can see in products 2 Bromides but in reactants just 1. And in reactants 2 NO₃ but as product just 1. Thus, you can balance the equation, thus:
<em>2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃</em>
And this equation is the answer of your question!
