Write the formula for simple interest.Use this formula to find the distance between the points (-1, -1) and (3, 3). Write the formula for the distance between two points.Round your answer to the nearest hundredth or give the exact square root answer. Find the length of the hypotenuse of an isosceles right triangle with legs of 5 units. _ The hypotenuse is represented by the letter _ and the two legs are represented by the letters _ and _. If the equation of a given line is y = x + 2, what is the slope of the line, and what is its.What is the sum of the interior angles of a regular pentagon?

Use the correct formula to find how many ounces of broth could be held in a cylinder that has a radius of 2 inches and a height of 7 inches if every cubic inch of volume contains one-fourth ounce of broth. Write the formula for the total surface area _ and the volume _ of a right circular cylinder.What is the volume of a sphere with a radius of 3 inches? _ Write the formula for the volume of a sphere.First generalizing the metal name and then. The reducing ability of the metals grows weaker while traversing down the series.DIRECTIONS: Refer to your FCAT Mathematics Reference Sheet to answer each of the following. Assigning meaningful things to the metal name guides to easily remember the reactivity series of periodic tables. These metals tarnish/corrode very easily. The metals at the top of the reactivity series are powerful reducing agents since they are easily oxidized. The only choice in which the metal undergoing oxidation is higher on the activity series. Long Tabular Form of the Reactivity Series Reactivity Series of Metals Ions Formed Lead Pb2+ Hydrogen H+ (Non-Metal, Reference for Comparison) Antimony Sb3+ Bismuth Bi3+ What is the effect of reactivity series on reducing power? The more active metal should be the one undergoing oxidation. What is the tabular form of the reactivity series? Therefore, the reactivity series of metals can be used to predict the reactions between metals and water. How can the reactivity series be used to predict chemical reactions?įor example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. It states like : Katrina ne car mangi Alto, zen, ferrari phirbhi kyu milli silver Audi. ![]() Most suitable and easy way to remember reactivity series (Hindi). How do you remember the spectrochemical series? If you carry on with physics at uni you’ll find that you learn how to explain/understand quite a few things that just have to be limited to memorization in A-level chemistry. ![]() Yes it is mostly memorization at A level. Organic Chemistry: It shouldn’t surprise you that organic chemistry takes the No. Which is the correct order of reactivity series Mg Ca Na K?Īnswer: Option (b) K < Na < Ca < Mg is correct answer. A metal placed at tire top of the activity series would displace metal below it. A metal placed above hydrogen in the activity series will displace hydrogen from water or acids. The arrangement of metals in the vertical column in the order of decreasing reactivity is called reactivity series or activity series. What is reactivity series How does the reactivity series? I’d learn it just to stay on the safe side, when I did GCSEs we had to learn the reactivity series so I don’t know if it’s changed for you. It says you need to “explain” things by using the reactivity series but it doesn’t say you have to “recall” it. I LIKE HIS CAR’S SILVERY GATE.ĭo you need to Memorise the reactivity series? ![]()
