Answer:
<em>Zinc nitrate is an inorganic chemical compound with the formula Zn(NO3)2. This white, crystalline salt is highly deliquescent and is typically encountered as a hexahydrate Zn(NO3)2•6H2O. It is soluble in both water and alcohol.</em>
Explanation:
correct me if im wrong please
6.060 has 4 significant figures including the zero after the decimal and the zero between non-zeros. 60.6 has 3 significant figures while 606 has also 3 significant figures. 60600 has 3 significant figures. Thus, the number with the greatest number of significant figures is 6.060.
Blood is a buffer solution of bicarbonate (HCO₃⁻) and carbon dioxide (CO₂). The Henderson equation which relates the concentration of HCO₃⁻ and CO₂ is given below:
=.
Respiring cell releases CO₂ in blood stream and that CO₂ on reaction with water molecule produces H₂CO₃ which is a weak base and its conjugate base is HCO₃⁻.
CO₂ + 2H₂O⇄ HCO₃⁻ + H₃O⁺
pH of the buffer solution (the blood) depends only on the ratio of the amount of CO₂ to the amount of HCO³⁻. [So, due to respiration produced CO₂ will get dissolved in water and favours the equilibrium towards forward direction. Then immediately HCO₃⁻ reacts with HCO₃⁻ and starts producing CO₂.]This ratio remains relatively constant because the concentrations HCO3- and CO2 are very large compared to the amount of CO₂ produced to the blood from respiring cells. So, of blood does not change.
Answer: Charles's law, Avogadro's law and Boyle's law.
Explanation:
Boyle's law is: at constant temperature PV = constant
Charles law is: at constant pressure V/T = constant
Avogadro's law is: at constant pressure ant temperature, equal volume of gases contain equal number of moles: V/n = constant
Ideal gas law: PV/nT = constant => PV = nT*constant = PV = nTR
