Terms in this set (13)The law of conservation of mass The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. Reactants a substance that takes part in and undergoes change during a reaction. Atom the basic unit of a chemical element Covalent bond A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. Diatomic consisting of two atoms. Element a part or aspect of something abstract, especially one that is essential or characteristic. Subscript (of a letter, figure, or symbol) written or printed below the line Chemical formula a mathematical relationship or rule expressed in symbols. Products an article or substance that is manufactured or refined for sale. Chemical reaction a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. Chemical equation A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. Coefficient a multiplier or factor that measures some property. Balanced chemical equation The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

ENGINEERING An open rectangular container contains a liquid that has a specific weight that varies according to the equation $\gamma=c_{1}+c_{2} h$, where $c_{1}$ and $c_{2}$ are constants and h is a vertical coordinate measured downward from the free surface. Derive an equation for the magnitude of the liquid force exerted on one wall of the container having a width b and height H and an equation that gives the vertical coordinate of this force.

ENGINEERING Free-surface problems are driven by gravity. Why do so many of the formulas contain the square root of the acceleration of gravity? Verified answer
ENGINEERING The acceleration due to gravity at an altitude y above the surface of the earth is given by $$ \begin{array}{lllllll}{y, m} & {0} & {30,000} & {60,000} & {90,000} & {120,000} \\ {g, m / s^{2}} & {9.8100} & {9.7487} & {9.6879} & {9.6278} & {9.5682}\end{array} $$ Compute g at y = 55,000 m.
