Interpretation:
The chemical equation for the reaction between calcium and
Concept introduction:
The alkaline earth metals react with water giving metal hydroxide, with the exception of beryllium. Beryllium does not react with water. Magnesium reacts with water at high temperatures. But calcium and strontium can react with water slowly at room temperature. This reaction produces metal hydroxide along with bubbles of hydrogen gas.

- Why is SnCl4 not classified as a salt?arrow_forwardIn 1774, C. Scheele obtained a gas by reacting pyrolusite (MnO2) with sulfuric acid. The gas, which had been obtained that same year by Joseph Priestley by a different method, was an element, A. (a) What is the element isolated by Scheele and Priestley? (b) Element A combines with almost all other elements. For example, with cesium it gives a compound in which the mass percent of A is 19.39%. The element combines with hydrogen to give a compound with a mass percent of element A of 94.12%. Determine the formulas of the cesium and hydrogen compounds. (c) The compounds of cesium and hydrogen with element A react with one another. Write a balanced equation for the reaction.arrow_forward(i) Write the electro-dot structures for sodium, oxygen, and magnesium(ii) Show the formation of Na2O and MgO by the transfer of electrons(iii) What are the ions present in these compounds?arrow_forward
- Write the equation for the reaction: when nitrogen gas (N2) reacts with sodium metal (Na), solid sodium nitride (Na3N) is formed.arrow_forwardAmong the following, determine which have similar chemical properties: Na, Mg, K, K+. Briefly explainarrow_forwardThe first three ionization energies of an element X are 900, 1745, and 14912 kJ·mol–1. What is the most likely formula for the stable ion of X?arrow_forward
- The Earth's atmosphere is made up of 78% Nitrogen and 21% Oxygen. The greater amount of Nitrogen than Oxygen in the atmosphere is due to* low temperature in the atmosphere. greater reactivity of nitrogen than Oxygen. greater reactivity of Oxygen than Nitrogen. more reactions producing Nitrogen. Which of the following elements has oxide that is amphoteric? (a)P (b) As (c) Sb (d) Pb a and b b and c c and d a and d The first four elements of Group 16 are called chalcogens because they are very reactive elements good oxidizing agen abundant in nature ore-forming elementsarrow_forwarda Write the chemical equation for the formation of the Ca(NH3 )6²+ .ion. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) Submitarrow_forwardIllustrated are four ions — A, B, X, and Y— showing their relativeionic radii. The ions shown in red carry positive charges: a2+ charge for A and a 1+ charge for B. Ions shown in blue carrynegative charges: a 1- charge for X and a 2- charge for Y.(a) Which combinations of these ions produce ionic compoundswhere there is a 1:1 ratio of cations and anions?(b) Among the combinations in part (a), which leads tothe ionic compound having the largest lattice energy?[Section 8.2]arrow_forward

My understanding is that in ionic bonds all atoms acquire stable configuration. Here potassium gives oxygen one electron. But oxygen needs two electrons to be stable. Hence it will not be stable.arrow_forwardPotassium superoxide, KO2, is often used in oxygen masks(such as those used by firefighters) because KO2 reacts withCO2 to release molecular oxygen. Experiments indicate that 2mol of KO2(s) react with each mole of CO2(g). (a) The productsof the reaction are K2CO3(s) and O2(g). Write a balanced equationfor the reaction between KO2(s) and CO2(g). (b) Indicatethe oxidation number for each atom involved in the reactionin part (a). What elements are being oxidized and reduced?(c) What mass of KO2(s2) is needed to consume 18.0 g CO2(g)?What mass of O2(g) is produced during this reaction?arrow_forward
