Concept explainers
Interpretation:
The formula of calcium chlorite should be identified form the given options.
Concept introduction:
The compounds which are formed between two elements are known as binary compounds and if one element is metal and another is non-metal, then the binary compound are made up of ions, known as binary ionic compounds.
First, the name of the metal should be identified with the help of its symbol.
The name of the non-metal should be identified with the help of its symbol and it is modified to end in “−ide”.
Polyatomic ions are those ions in which two or more atoms are joined with each other by covalent bonds. These ions are common, especially among non-metals.
Some non-metals form a sequence of oxoanions having different number of oxygen atoms. The name of these compounds are related with the oxidation state of non-metal atom to which oxygen atoms are bonded, ranging from hypo- (low) to per-(high) on the basis of number of oxygen atoms and oxidation state of non-metal.

- Assume that the radius of Earth is 6400 km, the crust is 50. km thick, the density of the crust is 3.5 g/cm3, and 25.7% of the crust is silicon by mass. Calculate the total mass of silicon in the crust of Earth.arrow_forwardThe carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.arrow_forwardThe present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.arrow_forward
- What is the mass of fish, in kilograms, that one would have to consume to obtain a fatal dose of mercury, if the fish contains 30 parts per million of mercury by weight?

- (1) Hydrofluoric acid, HF(aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). For example, sodium silicate, Na2SiO3, reacts in the following way Na2SiO3(s) + 8 HF(aq) → H2SiF6 (aq) + 2 NaF(aq) + 3 H2O(l) Atomic weights (g/mol): Na=23, Si=28, O=16, H=1, F=19 (a) Balance the above chemical equation that represents the reaction.
