Concept explainers
Interpretation:
The chemical formulas of calcium nitrate, barium chloride and ammonium phosphate has to be written. Also, the names and charges of all the ions in the given three compounds has to be given.
Concept Introduction:
An atom or a molecule having a net electrical charge is known as atom. Charge of the electron is negative and charge of the proton is positive. Both electron and proton have the same magnitude. Positively charged ion is called cation and negatively charged ion is called anion. Because of the opposite charge of cation and anion they will readily form ionic compounds. Ions consisting of only a single atom known as monoatomic ions and more than two atoms form polyatomic ions.

- Name and give symbols for three transition metals in the fourth period. Look up each of your choices in a dictionary, a book such as The Handbook of Chemistry and Physics, or on the Internet, and make a list of their properties. Also list the uses of each element.arrow_forwardGive the chemical formula of the acid. Your answer will be marked incorrect if you did not spelled the compound's name correctly. Please remember to include (aq) to your answer. Nitric acid Sulfuric acidarrow_forwardCa, Cl, Na, Fe, and K. Which of these elements form cations? List their symbols with charges. Which of these elements form anions? List their symbols with charges.arrow_forward
- Counting Atoms The formula for a compound indicates the elements that make up the compound and the number of atoms of each element present in the compound. These numbers of atoms are indicated by the use of small numbers called subscripts. Sometimes groups of atoms act as a single atom. When a subscript appears outside the parentheses, it indicates that all the elements inside the parentheses should be multiplied by that subscript. For example, the formula Fe(OH)3 indicates the combination of 1 atom of iron, Fe, 3 atoms of oxygen, O, and 3 atoms of hydrogen, H. In the following examples, list each element in the compound and the number of atoms of each element present. The first example has been done for you. You may already be familiar with some of the compounds. FIX ANY WRONG PROBLEMS! **Use the periodic table link to help you identify the elements used NAME USE FORMULA ATOMS IN FORMULA Calcium Carbonate Limestone CaCO3 Ca=1 calcium C = 1…arrow_forwardWrite the symbol for F, Cl, Br, I, O when they react to form ions. Are they cations or anions?arrow_forwardCreate a diagram to trace the development of the modern periodic table based on the observations on the properties of the elements? 3. Is the periodic table useful to you as a student? Justify your answer. 2. If you were to create a simple product using metals, nonmetals, and metalloids, what would your product be like? Sketch the design and composition of your product. Then, briefly explain what properties of each material are utilized in each part of the product. 4.arrow_forward
- Some of the names below are incorrect. Beside each name, write an “X” for an incorrect name and a “✔” for a correct name. For each incorrect name, explain what is wrong and why it is incorrect. I attatched the chart as well as my answers. I was unsure if the ending of the polyatomic names were changed to "ide" or not. I have also found that some periodic tables have more charges on elements than others, so I wasn't sure if Chlorine was a multivalent metal or not, as different periodic tables said different things. Thanks.arrow_forwardThe element X has two naturally occurring isotopes. The masses (amu) and % abundances of the isotopes are given in the table below. The average atomic mass of the element is amu. Isotope | Abundance (%) | Mass (amu) 31x 35.16 31.16 34x 64.84 34.30 O 35.22 O 30.20 O 32.73 O 33.20 О 34.02arrow_forwardWhat chemical test(s) could you use to distinguish solid barium chloride from solid barium sulfate?arrow_forward
- Present 5 chemical reactions involved in biological and industrial processes affecting life and the environment. Give the reactants and products from the chemical reactions. Write the chemical formula of each of the reactants and products.arrow_forwardThere are two gas compounds that are made out of element A and B. This is the mass percentage of the two compounds. Compound 1: 30.43% A, 69.57% B Compound 2: 63.64% A, 36.36% B In a normal state element A and B exist as a gas. (It can be mono atomic molecule, diatomic molecule or triatomic molecule) When you react gas A and gas B and make a product these things come out. (All in same temperature and pressure) 1 Volume of Gas A + 2 Volume of Gas B = 2 Volume of Compound 1 2 Volume of Gas A + 1 Volume of Gas B = 2 Volume of Compound 2 Determine the relative mass of element A and B from the reaction formula above. Also you should assume the simplest chemical formula of reactant and productsarrow_forwardIn 1808 John Dalton published his atomic theory which was quickly adopted. The five tenets of Dalton's theory are An element is composed of tiny indivisible, indestructible particles called atoms. All the atoms of an element are identical and have the same properties. Atoms of different elements combine to form compounds. Compounds contain atoms in ratios of small whole numbers. Atoms can combine in more than one ratio to form different compounds. Although all of the statements were valid at the time, several have been modified as new discoveries were made. Which of these tenets have been modified? What caused the modification?arrow_forward
