Ammonia (NH3) reacts with oxygen (O2) to produce nitrogen monoxide (NO) and water (H2O). Write and balance the chemical equation
bekas [8.4K]

Answer:

There is 1.6 L of NO produced.

Explanation:

I assume you have an excess of NH3 so that O2 is the limiting reagent.

<u>Step 1:</u> Data given

2.0 liters of oxygen reacts with ammonia

<u>Step 2:</u> The balanced equation

4NH3 + 5O2 → 4NO + 6H2O

For 4 moles of NH3, we need 5 moles of O2 to produce 4 moles of NO and 6 moles of H2O

Consider all gases are kept under the same conditions for pressure and temperature, we can express this mole ratio in terms of the volumes occupied by each gas.

This means:  when the reaction consumes  4  liters of ammonia (and 5 liters of oxygen) it produces  4  liters of nitrogen  monoxide

Now, when there is 2.0 liters of oxygen consumed, there is 4/2.5 = 1.6 L of nitrogen monoxide produced.

There is 1.6 L of NO produced.

draw the lewis structure for pcl6, then answer the following questions: 1. how many valence electrons does this compound have? 2
DedPeter [7]

The Pcl6 has 48 bonded electrons and 18 lone pairs.

The Lewis structure of Pcl6 is as follows: -

Phosphorous is bonded with 6 chlorine atoms with 18 lone pairs.

Lewis structures, also known as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds.

    In Lewis structure, atoms are bonded with single bonds. If total number of electrons are 't' and number of bonds are 'n', then t-2n number of electrons are to be placed. Once the central atom is placed, they need to complete the octet rule.

Student Exploration: Limiting Reactants Vocabulary: chemical equation, chemical formula, chemical reaction, coefficient, limitin
SIZIF [17.4K]

Answer:

30 hot dogs

Explanation:

It is given that :

There are 4 packets of eight wieners, i.e. 4 x 8 = 32 wieners

There are 3 bags of ten buns, i.e. 3 x 10 = 30 buns

One hot dogs need 1 bun and 1 wiener to make a hot dog.

There are 30 buns, so 30 hot dogs can be made out by using all the 30 buns and the 30 wieners out of the 32 wieners.

Therefore, 30 hot dogs.

And the number of extra wieners left = 32 - 30 = 2 wieners.
