Balance the below equation:

svet-max [94.6K]

Answer:

4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (l)

This is an oxidation-reduction (redox) reaction:

4 N-III - 20 e- → 4 NII

(oxidation)

10 O0 + 20 e- → 10 O-II

(reduction)

NH3 is a reducing agent, O2 is an oxidizing agent.

The surfaces of the cylinder block and cylinder head are _______ to help cool the engine.

Softa [21]

The surfaces of the cylinder block and cylinder head are interconnected to help cool the engine.

When an automobile engine is running, it generates a lot of heat and needs to be continuously cooled to prevent engine damage.

This is typically accomplished by pumping coolant liquid—often water combined with antifreeze solution—through unique cooling tubes. Air passing across cylinder casings with fins helps cool some engines.

The cylinder head and block of a water-cooled engine are interconnected by coolant channels. All of the channels come together to form a single exit at the top of the cylinder head.

Hot coolant is forced out of the engine and into the radiator, which serves as a type of heat exchanger, by a pump that is driven by a pulley and belt from the crankshaft.

Unwanted heat is transferred from the radiator into the air stream, after which the cooled liquid flows back into the channels after returning to an entrance at the bottom of the block.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 2C + O₂ → 2CO₂

[Given] 0.25 moles O₂

[Solve] moles CO₂

<u>Step 2: Identify Conversions</u>

[RxN] 1 mol O₂ → 2 mol CO₂

<u>Step 3: Stoichiometry</u>

[DA] Set up: $\displaystyle 0.25 \ moles \ O_2(\frac{2 \ mol \ CO_2}{1 \ mol \ O_2})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 0.5 \ mol \ CO_2$
