Answer:
Larynx
Explanation:
The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea.
Answer: D.
Explanation:
Le Chatelier's Principle states that when a Chemical reaction in equilibrium experiences some change, whether that's a temperature change, a pressure change, or a concentration change, the equilibrium will shift to annul the effect of that change.
Complex a: <span>tetrachlorocuprate(i)
In present complex chlorine is negatively charged ligand (-1) and oxidation state of copper is +1. Therefore, total charge on complex = 4(-1) + 1 = -3
Complex b: </span><span>pentaamminechlorocobalt(iii)
In present complex, ammine is a neutral ligand (charge = 0), chlorine is negatively charged ligand (charge = -1) and oxidation state of Co is +3. Therefore, total charge on complex is 5(0) + (-1) + (+3) = +2
</span><span>Complex c: diaquadichloroethylenediaminecobalt(iii)
</span>In present complex, aqua is a neutral ligand (charge = 0), chlorine is a negatively charged ligand (charge = -1), ethylenediamine is a neutral ligand (charge = 0) and oxidation state of cobalt is +3. Therefore, total charge on complex is 2(0) + 2(-1) + 2(0) + 3 = +1.
gold density = 19.3 g/cm³
mass = 16.5 kg = 16.5 x 10³ g
volume = 954 ml
gold density based on the experiments:
ρ = 16.5 x 10³ g / 954 ml(cm³) = 17.296 g/cm³ ( not of pure gold)
its density should stay the same as it is a characteristic property and nothing was added sooo
