Answer:

Chemical equation:

HNO₃ + Al(OH)₃   →  Al(NO₃)₃ + H₂O

Explanation:

Chemical equation:

HNO₃ + Al(OH)₃   →  Al(NO₃)₃ + H₂O

Balanced chemical equation:

3HNO₃ + Al(OH)₃   →  Al(NO₃)₃ + 3H₂O

Ionic equation:

3H⁺ + 3NO⁻₃(aq) + Al(OH)₃(s)   →  Al³⁺(aq) + 3NO₃⁻¹(aq) + 3H₂O(l)

Net ionic equation:

Al(OH)₃(s)  +  3H⁺(aq)     →  Al³⁺(aq) +  3H₂O(l)

The NO⁻₃ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.

Explain why gases such as the oxygen found in tanks used as hospitals are compressed. why must care be taken to prevent compress
allochka39001 [22]

They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode. Before compressed oxygen can be breathed, it must be decompressed.

Several narrow linear bloodstain patterns are found on a wall adjacent to one where a body was found the droplets were elongated
ryzh [129]
The correct answer is letter D. A knife would most likely cause this blood spatter pattern because of the direction of the force that was inhibited on the weapon and the victim. The direction of the spatter will also depend on the body part that was hit by the weapon.

Given the heat change per mole for the combustion of methanol (-726 kJ/mol), predict the heat change that would occur if 0.200 m
DochEvi [55]

Answer:

-145.2kJ

Explanation:

Enthalpy is an extensive property as its value depends on the amount of substance present in the system.

If the enthalpy for one mole of methanol = -726 kJ/mol;

The Enthalpy for 0.2 mol is given as;

Enthalpy = 0.200 * 726

Enthalpy = -145.2kJ

It would take -145.2kJ for 0.200 mol of methanol to undego the combustion reaction.
