Answer:

The answer to your question is B. double bond.

Explanation:

Both alkanes and alkenes are hydrocarbons composed by carbon and hydrogen.

The different between these compounds is that alkanes have only single bonds are are represented as:         H    H

                                                            |     |

                                                     H - C - C - H

                                                            |      |

                                                           H    H

Alkenes have at least one double bound in their structure and are represented as

         

                                                   H - C = C - H

                                                          |      |

                                                          H    H

Ammonia gas can be prepared by the following reaction:CaO(s) + 2NH4Cl(s) ------&gt; 2NH3(g) + H2O(g) + CaCl2(s)In an experiment,
Andrei [34K]

Answer:

The theoretical yield of NH3 = 54.9 grams

The actual yield of NH3 = 26.5 grams

The % yield = 48.3 %

Explanation:

Step 1: Data given

Mass of NH3 produced = 26.5 grams

54.9 grams of NH3 was predicted

Step 2: The balanced equation:

CaO(s) + 2NH4Cl(s) → 2NH3(g) + H2O(g) + CaCl2(s)

Step 3: Theoretical yield

The theoretical yield, is the amount of NH3 that is predicted to be formed = 54.9 grams

The actual yield is the amount of NH3 that actual has been formed = 26.5 grams

% yield = (actual yield / theoretical yield)*100 %

% yield = (26.5 grams / 54.9 grams) * 100%

% yield = 48.3 %

1. What is the frequency of light having a wavelength of 406 nm?
morpeh [17]

Answer:

1. frequency = 7.39 * 10¹⁴ Hz

2. wavelength = 1.44 * 10⁸ nm

Explanation:

The speed, frequency and wavelength of waves are related by the formula;

speed = wavelength * frequency

1. wavelength of light = 406 nm = 4.06 * 10⁻⁷ m

speed of light is a constant = 3.0 * 10⁸ m/s

From the formula above, frequency = speed / wavelength

therefore, frequency = (3.0 * 10⁸ m/s) / 4.06 * 10⁻⁷ m

frequency = 7.39 * 10¹⁴ Hz

2. From the equation above, wavelength = speed/frequency

speed of radiation = 3.0 * 10⁸ m/s

frequency = 2.09 * 10⁹ Hz or 2.09 * 10⁹ s⁻¹

therefore, wavelength = (3.0 * 10⁸ m/s) / 2.09 * 10⁹ s⁻¹

wavelength = 1.44 * 10⁸ nm

kobusy [5.1K]

Answer:

Benzoic acid

Explanation:

In writing the name of a compound, we usually leave a space where necessary in order to prevent ambiguity.

For instance, the compound written above is rightly named benzoic acid. The space must be left between the two words in order to prevent ambiguity in the given name of the compound.

Answer:

where a cold air mass is replacing a warmer air mass. ... The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour.

Explanation:

The effects from a cold front can last from hours to days. The air behind the front is cooler than the air it is replacing and the warm air is forced to rise, so it cools. As the cooler air cannot hold as much moisture as warm air, clouds form and rain occurs.
