Sphinxa [80]

Electrical conductivity, electromagnetism, and temperature are the features that one would look for in order to determine plasma. Plasma refers to a hot ionized gas possessing high electrical conductivity. It is electrically neutral with negative and positive particles. It can be considered the most abundant form of matter in the universe.  

The features of plasma are substantially distinct from those of the usual neutral gases so that plasmas are regarded as a different fourth state of matter.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Question no 1:</h2><h3>CATION:</h3>

Cation is the postively charged unit which is formed by the transfer of one or more electrons. It is attracted towards cathode thus it is called the CATION.

<h2>_____________________________________</h2><h2>Question no 2:</h2><h3>IONIC BOND:</h3>

Ionic bond is the type of bond which is formed between the positive and negative ions. It is mostly formed between the Metals (i.e. group 1 and 2) and Non metals (i.e. mostly group 7). The positive charge on metal is due to the loosing of electron and negative charge on non metal is due to accepting the electron.

<h2>_____________________________________</h2><h2>Question no 3:</h2><h3>POLYATOMIC ION:</h3>

A molecular ion is a covalently bonded set of two or more atoms, that can be considered to behave as a single unit, it also has a charge on it.

<h2>_____________________________________</h2><h2>Question no 4:</h2><h3>CONDUCTIVITY:</h3>

Conductivity is more in liquid than in solid because the conductivity is flow of electron and the movement is less in solid than liquids thus the solid has less conductivity. The liquid has more movement of molecules due to which there is more conductivity.

<h2>_____________________________________</h2><h2>Question no 5:</h2><h3>FORMULA UNIT: </h3>

Formula unit is a emperical formula used to express the ions in ionic compounds. It is the least whole number ratio of the ions present in the ionic compound.

<h2>_____________________________________</h2><h2>Question no 6:</h2><h3>CRYSTAL LATTICE:</h3>

Crystal lattice is the arrangement of atoms, molecules, or ions of a crystal in the form of a three dimensional space lattice.

<h2>_____________________________________</h2><h2>Question no 7:</h2><h3>ANION:</h3>

Anion is the negative charged because It receives one electron from the cations thus becomes negatively charged entity. It is attracted towards the positive anode thus it is called anion.

<h2>_____________________________________</h2><h2>Question no 8:</h2><h3>MOLECULES:</h3>

Ionic bond do not form molecules, They form the ions.

<h2>_____________________________________</h2><h2>Question no 9:</h2><h3>Attraction:</h3>

One type of bonding i.e. ionic bonding is formed by the attraction between the positive and negative ions.

<h2>_____________________________________</h2><h2>Question no 10:</h2><h3>LATTICE ENERGY:</h3>

It is the amount of energy required to change the state of matter.

If 5 L of butane is reacted what volume of carbon dioxide is produced ILL GIVE BRAINLIEST
Len [333]

Answer: First, here is the balanced reaction:  2C4H10  +  13O2  ===>  8CO2  +  10H2O.

This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.

Next, let's determine how many moles of butane are burned.  This is obtained by

5.50 g / 58.1 g/mole  =  0.0947 moles butane.  As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947  =  0.1894 moles CO2.

Now we need to figure out the volume.  This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions:  273 K and 1 atmosphere.

We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).

V = 0.1894 x 0.082 x 273.0 / 1  =  4.24 Liters.
