Which element has a higher ionization energy than silicon? Magnesium, Germanium, Sodium, or Phosphorus

Chemistry
1 answer:
Fiesta28 [93]3 years ago
7 0

Answer:

Phosphorus

Explanation:

Phosphorus will have higher ionization energy than silicon from the given choices.

Ionization energy is the energy required to remove the most loosely held electron in an atom.

Based on the periodic trends:

  • Across the period, ionization energy increases from left to right
  • Down a group, ionization energy decreases.

Since phosphorus is the element in the right most part after silicon, it has higher ionization energy

How many seconds are in a 5.5 ms
deff fn [24]

Answer:

0.0055 seconds

Explanation:

To answer this question you need to know the equivalence:

1 second (s) = 5.5 (miliseconds) (ms)

Then you use the conversion factor:

-Put the value given and the units:

5.5ms

- Put in the denominator the equivalence with the same units:

5.5ms*\frac{}{1000ms}

- Put in the numerator the unit at which you want to convert the value given:

5.5ms*\frac{1s}{1000ms}

- Then multiply and divide the quantities:

5.5ms*\frac{1s}{1000ms}=0.0055 s

Note that the same units in numerator and denominator are cancelled.

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.
