The acronym "OIL RIG" is used to help remember this.: "Oxidation Is Loss, Reduction Is Gain" You may first have heard oxidation in relation to say, rusting of iron where we say Iron has been oxidised: "Iron" + "oxygen" to "hydrated iron (iii) oxide" Although the formation of an oxide helps make an intuitive link to iron being oxidised, we can ...
2 When evaluating expressions with color (blue)"mixed operations" there is a particular order that must be followed. Follow the order as set out in the acronym PEMDAS. 16- (4+3)xx2larr" brackets first" rArr16-7xx2larr" next multiplication" rArr16-14larr" finally subtraction" =2
There is an acronym that defines the order of steps in which this expression should be evaluated, so you can use it, or just start with the most complicated stuff and work down to the easy steps. Given: 4^22+87 Has an exponent or power of in it, so we will take care of that first: 4^2=44=16to so we can see: 4^22+87=162+87 Then there are two multiplications so we tackle them next: 162 ...
Electric Meters usually measure in KWH units. KWH is acronym for Kilo Watt Hour. It's basically units of Work/Energy. You can do the math for the Kilo Watt Hour. It's simple. KWH = 1000* 6060 Watt-Sec rArr KWH = 3.610^6 Watt-Sec We know that, Power = (Work)/(Time) Units of Power are Watt, Work are Joules and Time are Seconds. So, Watt-Sec is nothing but Joules. So, KWH=3.6Mega Joules One KWH ...
