Interpretation:
The balanced chemical equation when lithium reacts with water hasto bewritten.
Concept Introduction:
Balanced Chemical equation:
A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.

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_forward(a) Which poisonous gas is evolved when white phosphorus is heated with Cone. NaOH solution? Write the chemical equation. (b) Write the formula of first noble gas compound prepared by N. Bartlett. What inspired N. Bartlett to prepare this compound? (c) Fluorine is a stronger oxidising agent than chlorine. Why? (d)Write one use of chlorine gas.arrow_forward
- Which property of the group 6A elements might be the onedepicted in the graph shown here: (a) electronegativity,(b) first ionization energy, (c) density, (d) X¬X single-bondenthalpy, (e) electron affinity?arrow_forwardEach of the chemically active Period 2 elements forms sta-ble compounds that have bonds to fluorine.(a) What are the names and formulas of these compounds?(b) Does ΔEN increase or decrease left to right across the period?(c) Does percent ionic character increase or decrease left to right?(d) Draw Lewis structures for these compounds.arrow_forwardIodine monochloride and elemental bromine have nearly the same molar mass and liquid density but very different boiling points.(a) What molecular property is primarily responsible for this difference in boiling point? What atomic property gives rise to it? Explain.(b) Which substance has a higher boiling point? Why?arrow_forward
- Give TWO reasons why aluminium metal was not commonly used till last century, even though it is one of the most common elements on earth. (b) Why are copper and lithium such important elements today?arrow_forwardUntil the early 1960s the group 8A elements were called the inert gases; before that they were called the rare gases. The term rare gases was dropped after it was discovered that argon accounts for roughly 1% of Earth’s atmosphere. (a) Why was the term inert gases dropped? (b) What discovery triggered this change in name? (c)What name is applied to the group now?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).
