- Write the chemical formulas for (a) potassium sulfide, (b) calcium hydrogen carbonate c) nickel(II) perchlorate. for (d) silicon tetrabromide, (e) disulfur dichloride.arrow_forwardSome salts make hydrates when there is moisture around. Some hydrate samples can absorb lights in visible legion. Therefore, they show some colors. Thus, hydrates can be used to detect the moisture in the environment. Let's say you are working in a laboratory with a group and you are the only student who has taken chemistry courses. Your laboratory received a sample of cobalt(II) chloride which has the formula CoCl2·xH2O. Let's say your boss asked you to find the formula of this hydrate salt sample since you are the only chemist there. From your laboratory experience, simply explain the experimental procedure you would follow to find the formula of this unknown sample. Then, use the given data for the calculation part. Mass of crucible: 32.27g Mass of crucible + unknown hydrate: 33.92 g Color of unknown hydrate: purple Mass of crucible + anhydrous form of hydrate: 33.41 g Color of anhydrous form: sky bluearrow_forwardElemental chlorine exists in nature as diatomic molecules of Cl2. Could the process you used to describe the formation of NaCl account for this compound? Why or why not?arrow_forward
