Answer:
The answer is glucose (C6H12O6)
Explanation:
1) A balanced equation for the reaction.
2) The name of the soluble slat produced by reaction between magnesium and hydrochloric acid is magnesium chloride.
Magnesium chloride =
3)Yes, chemical change has been taking.
This is because rearrangement of atom is taking place which resulted in formation of hydrogen gas amd magnesium chloride.
4) Moles of hydrogen gas produced = 2 mole
According to reaction, 1 mole of hydrogen gas is obtained from 2 moles of HCl.
Then 2 moles of hydrogen gas will be obtained form:
of HCl
4 moles of acid has reacted.
Answer:
2.22 × 10^-5M
Explanation:
From Beer-Lambert's law;
A=εcl
Where A = absorbance of GMP= 0.2
ε= molar extinction coefficient of GMP = 9000 M-1cm-1
c= concentration of GMP= the unknown
l= path length = 1 cm
c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm
c= 2.22 × 10^-5M
