Answer:

The correct answer is "Layer A is the stratosphere and Layer B is the troposphere".

Explanation:

The stratosphere is the layer of the Earth's atmosphere at which different layers of temperature are found, therefore it has a "stratified" temperature. The stratosphere contains the ozone layer, which absorbs harmful radiation, which regulates temperature. On the other hand, troposphere is the layer of the Earth's atmosphere that is closest to the ground, at which all weather's phenomena takes place. Therefore, a weather phenomenon such as water cycle causing wind takes place at the troposphere.

which of the following pairs of elements could react to form an ionic compound? A. potassium and calcium B. sulfur and oxygen C.
Grace [21]
The correct option is FLUORINE AND COPPER.
An ionic compound is usually formed by the combination of a metal and a non metal, the metal usually act as an electron donor while the non metal act as an electron acceptor. Thus, in ionic compounds, there is total transfer of electrons from the metal to the non metal. In the question given here, copper is the metal while the fluorine is the non metal.<span />

Engineers are developing a process to produce phosphorus pentachloride.
Alchen [17]

Answer:

Options B and C are the two criteria that are most essential

Explanation:

When trying to develop a novel process, <u>it is important that the new process involves the use of equipment that can be operated safely by workers so as to prevent death or injury in the cause of handling this equipment</u>. If this equipment is seen not to be safe or cannot be handled safely by workers, it can/will force workers to previous or alternative methods that require more safe equipment.

Also, the process must be able to maximize the most of the reactants, i.e <u>the process must be able to convert a good percentage of the reactants into the desired product (phosphorus pentachloride) since that is the focus</u>. This will also lead to reduction of byproducts produced which could be useful or otherwise (a loss).

How much heat is released when 1.4 mol of hydrogen fluoride are produced? H2(g) +F2(g) → 2HF(g) +536kJ (Please show work)
polet [3.4K]

Answer:

375.2 kJ

Explanation:

  • H₂(g) +F₂(g) → 2HF(g) +536kJ

The information the equation above provides lets us know that when 2 mol of hydrogen fluoride (HF) are produced, 536 kJ of energy (as heat) is produced.

We can then <u>state a rule of three</u>:

  • 2 mol HF --------  536 kJ
  • 1.4 mol HF --------- X

And <u>solve for X</u>:

  • X = 1.4 mol * 536 kJ / 2 mol
  • X = 375.2 kJ
