Answer:

Biodiesel has a higher oxygen content (usually 10 to 12 percent) than petroleum diesel. ... Biodiesel is more chemically active as a solvent than petroleum diesel. As a result, it can be more aggressive to some materials that are normally considered safe for diesel fuel. Biodiesel is much less toxic than petroleum diesel.

Write the net ionic equation for this reaction occurring in water: ammonium fluoride and magnesium chloride are mixed to form ma

MAXImum [283]

Correct answer: 3. $Mg^{2+}(aq) + 2 F^{-}(aq) --> MgF_{2}(s)$

The given chemical reaction is between ammonium fluoride and magnesium chloride to form magnesium fluoride and ammonium chloride.

The balanced chemical equation representing the reaction will be,

$2NH_{4}F (aq) + MgCl_{2}(aq) -->MgF_{2} (s) + 2NH_{4}Cl (aq)$

The complete ionic equation for the reaction: All the compounds soluble in water (aqueous) will split into ions, $MgF_{2}$ will not split into ions as it is insoluble in water.

$2 NH_{4}^{+}(aq) + 2 F^{-}(aq) + Mg^{2+}(aq) + 2 Cl^{-}(aq) --> MgF_{2}(s) + 2 NH_{4}^{+}(aq) + 2 Cl^{-}(aq)$

The net ionic equation will be:

$Mg^{2+}(aq) + 2 F^{-}(aq) --> MgF_{2}(s)$

Here the spectator ions are $NH_{4}^{+} and Cl^{-}$

What volume will 2.00 moles of nitrogen occupy at 720 torr and 20C?

bija089 [108]

Answer:

50.62L

Explanation:

1torr= 0.00132atm

P=720torr = 0.95atm

V= 20°C= 20+273= 293K

PV=nRT

R=0.08206L-atm/mol-K

0.95×V= 2×0.08206×293

V= 2×0.08206×293/ 0.95

V= 50.62L
