DO NOT include the units in your answer.arrow_forwardObtain an estimate for the number of atoms in the universe. Make the following assumptions: (a) All of the atoms in the universe are hydrogen atoms in stars. (This is not a ridiculous assumption because over threefourths of the atoms in the universe are in fact hydrogen. Gas and dust between the stars represent only about 15% of the visible matter of our galaxy, and planets compose a far smaller fraction.) (b) The sun is a typical star composed of pure hydrogen with a density of 1.4 g/cm^3 and a radius of 7x10^8 m. (c) Each of the roughly 100 billion stars in the Milky Way galaxy contains the same number of atoms as our sun. (d) Each of the 10 billion galaxies in the visible universe contains the same number of atoms as our Milky Way galaxy.arrow_forwardWhich is correct and which is incorrect from the following sentences? Proposition True False (a) The nitrogen ions N + and oxygen O + are products of the decay of the corresponding molecules under the influence of sunlight near the earth's surface. (b) Red phosphorus is more active than white phosphorus and is therefore used in the manufacture of matches. (c) The oxidation number (a.o.) of nitrogen in all chemicals NO, NO + and NO- is +2. (d) Of the elements Al, Cl2, Na, Mg and Ca, only Na reacts with cold water to produce H2. (e) Of the two common carbon oxides, monoxide is less acidic.arrow_forward

- Matter is neither created nor destroyed in a chemical reaction. Thus, the mass of the products of a chemical reaction must be equal to the mass of the starting materials. Formally, this concept is called the law of conservation of mass. A sample of sodium reacts completely with 0.426 kg k g of chlorine, forming 702 g g of sodium chloride.
