Answer:

Chemical energy

Explanation:

An atom is the basic unit of a chemical element.

A chemical bond held together with atoms, ions, or molecules that leads to the formation of chemical compounds. A chemical bond may be covalent, polar covalent, or ionic. Among these chemical bonds, an ionic bond is the strongest chemical bond.

Chemical energy is stored in the chemical bonds between atoms.

Where would the electrons in the 3d sublevel be found? Possibly in any shell only in the n = 3 energy level in energy levels &gt
postnew [5]

Answer:

In the n = 3 energy level

Explanation:

There's is no further explanation for this.

All the electrons in an energy level are distribuited according to the period in the periodic table they are.

So, if we have an atom in period 1, like Hydrogen (H), that atom would only have 1 level energy (n = 1) and in that level, we only have the sub level 1s.

Electrons in the 3d sublevel, are found mostly in all the transition metals of period 3, and it can go from 1 to 10 electrons. To be with the 3d sub level it's neccesary that the energy level to be 3.

energy levels beyond that, like n = 4, we have electrons occupying the 3d sub level, so, primordly, the 3d is found only in energy level 3.

Hope this helps

Define natural gas, liquefied petroleum gas (LPG), and liquefied natural gas (LNG). What three countries have most of the world’
mrs_skeptik [129]

Answer:

The answer is treated below.

Explanation:

<u>Natural gas</u>: Natural gas is not used in its pure form; it is processed and converted into cleaner fuel for consumption. It is a fossil fuel composed almost entirely of methane, but contain small amounts of other gases, including ethane, propane, pentane and butane. It is a combustible,  gaseous mixture of simple hydrocarbon compounds, usually found in deep  underground reservoirs formed by porous rock. Natural gas is mainly used as fuel for generating  heat  and electricity.

<u>Liquefied petroleum gas (LPG)</u>: Liquefied Petroleum Gas is a byproduct of natural gas and oil extraction and crude oil refining . At room temperature,  liquefied petroleum gas is a colourless and odourless gas which consists generally of butane (C4H10) or propane (C3H8) or a mixture of both.

<u>Liquefied natural gas (LNG)</u>: Is natural gas that has been liquefied for ease of transport or storage. It is refrigerated to a very low temperature (-162 Celsius). At this temperature it becomes an odourless, non-toxic liquid that can be safely transported over long distances.

<u><em> Three countries that have most of the world’s natural gas reserves</em></u>

  1. Russia
  2. Iran
  3. Qatar

<em>Major advantages of using conventional natural gas as an energy resource:</em>

  • It is less expensive when compared to other fossil fuels.
  • It is safer and easier to store when compared to other fossil fuels

<em>Major disadvantages of using conventional natural gas as an energy resource:</em>

  • It costs more to recover the remaining natural gas because of flow, access, etc.
  • It is not a renewable source.
  • it is a combustible material, It must be handled with care.
  • It does not contribute to greenhouse gases.

Three sources of unconventional natural gas :

  1. <em>Tight Gas</em>
  2. <em>Shale Gas</em>
  3. <em>Coalbed Methane</em>

<u>Major problems related to the use of </u><u>Tight Gas</u>

  • When Hydrofluoric acid is used to release tight gas in reserves it potentially an issue simply because the substance is so dangerous. A spill or a leak could harm workers and pollute groundwater for uses.

<u>Major problems related to the use of </u><u>Shale Gas</u>

  • Risk of ground and surface water contamination.
  • Have impacts on air quality.

<u>Major problems related to the use of </u><u>Coalbed Methane</u>

  • The development of coalbed methane will result to soil disturbance from construction of wells, roads, and the associated pipeline and electric power rights-of-ways.
  • It has impact on wildlife.

1.How many mL of 0.401 M HI are needed to dissolve 5.97 g of BaCO3?
garri49 [273]

Answer:

The answer to your question is:

1.- volume = 0.151 l or 151 ml

2.- 0.241 l  or 241 ml of NaOH

Explanation:

1.-

Data

V = ? HI = 0.401 M

BaCO3 = 5.97 g

                     2HI(aq)    +    BaCO3(s)   ⇒   BaI2(aq) + H2O(l) + CO2(g)

MW BaCO3 = 137 + 12 + 48 = 197 g

                     197 g of BaCO3 ----------------- 1 mol

                     5.97 g                -----------------   x

                     x = (5.97 x 1) /197

                    x = 0.03 mol of BaCO3

                    2 moles of HI ----------------  1 mol of BaCO3

                    x                     ----------------  0.03 mol of BaCO3

                    x = (0.03 x 2) / 1

                   x = 0.060 mol of HI

Molarity = moles / volume

volume = moles / molarity

volume = 0.060 / 0.401

volume = 0.151 l or 151 ml

2.-

V = ?    NaoH 0.757 M

Co⁺² Volume = 167 ml   0.548 M

             CoSO4(aq) + 2NaOH(aq)   ⇒   Co(OH)2(s) + Na2SO4(aq)

Moles of Co = Molarity x  volume

Moles of Co = 0.548 x 0.167

Moles of Co = 0.092

                                 1 mol of CoSO4 -------------- 2 moles of NaOH

                                0.092 moles      ---------------   x

                                x = (0.092 x 2) /1

                               x = 0.183 moles of NaOH

Volume of NaOH = moles / molarity

                             = 0.183 / 0.757

                            = 0.241 l  or 241 ml of NaOH
