Apr 7, 2016 · Yes, it has no positive factors apart from 1 and 101. To test if 101 is prime, check for divisibility by each of the primes 2, 3, 5 and 7. There is no need to check beyond these as 11^2 = 121 > 101. So if 101 was divisible by some number less than 101 then it would be divisible by a number less than 11. 101 is not divisible by 2 since it ends with an …

Dec 25, 2013 · The equation for the Ideal Gas Law is: PV = nRT On the whole, this is an easy equation to remember and use. The problems lie almost entirely in the units. SI units Pressure, P Pressure is measured in pascals ("Pa") — sometimes expressed as newtons per square metre ("N·m"^"-2"). These mean exactly the same thing. Be careful if you are given pressures in kilopascals ("kPa"). For example, "150 ...

Jun 16, 2016 · The complete electron for a neutral arsenic atom is: "1s"^2"2s"^2"2p"^6"3s"^2"3p"^6"3d"^(10)"4s"^2"4p"^3 Its shorthand electron configuration is: ["Ar"]"3d"^(10)"4s"^2"4p"^3 As is the chemical symbol for the element arsenic. Its atomic number is 33, which is the number of protons in the nuclei of its atoms. In a neutral atom, the number of electrons equals the number of protons, which means ...

Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction. It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of …

Apr 23, 2014 · The balanced chemical equation is: Mg_((s))+ 2HCl_((aq))rarrMgCl_(2(aq)) + H_(2(g) The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas. I hope this was helpful. SMARTERTEACHER You can watch this reaction in the ...

Feb 16, 2017 · Count the numbers to get the count. Divide the sum by the count to get the arithmetic mean. 4+7+8+12+13+16+20+21 = 101 -> the sum. There are 8 numbers, so 101 / 8 = 12.625 The arithmetic mean is 12.625. For the median, take the list of numbers in numeric order and count them i.e. 8. Look for the middle number in the list.

Aug 21, 2016 · The equilibrium constant of a reaction under the general form: #A(g)+B(g)rightleftharpoonsC(g)+D(g)# can be calculated by the general expression of #K_(eq)# as follows:
