Write a molecular equation for the precipitation reaction that occurs (if any) when the following solutions are mixed. If no reaction occurs, write NO REACTION. Express your answers as a chemical equation. Identify all of the phases in your answer. a. b.
15/3/2013· The modified MHS equation is: η = 2.45 D P v 0.70 = 0.070 M v 0.70. Appliion of the equation provides the true viscosity average DP (DP v ) for any type of distribution. In contrast, the apparent ‘DP v ’ referred to in standard methods (ASTM, SCAN) is an undefined type of average DP which depends on the chain length distribution, and may differ considerably from both DP v and DP w .
You may notice that in a complete ionic equation, some ions do not change their chemical form; they stay exactly the same on the reactant and product sides of the equation. For example, in Na + (aq) + Cl − (aq) + Ag + (aq) + NO 3 − (aq) → AgCl(s) + Na + (aq) + NO 3 − (aq)

28/1/2020· Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. Usually, this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation to indie they are in aqueous solution.

Assuming a quasi-stationary turbulent kinetic energy equation, the shear production equals the molecular frictional heating minus the adiabatic conversion that takes place at the turbulent scale (e.g., van Mieghem 1973).
Write a net ionic equation to show that quinoline, C9H7N, behaves as a Bronsted-Lowry base in water. asked by Leslie on April 17, 2013 Chemistry A beaker of nitric acid is neutralized with calcium hydroxide. Write a balanced molecular equation and
14/1/2009· My teacher is pretty strict about details, and Im working on an assignment about writing/balancing chemical reactions. The question is: When heated, calcium carbonate decomposes to form calcium oxide and carbon dioxide. Write the equation for this reaction. He
Write the overall equation including the correct designations for the physical state of the substances (s, l, g, aq). Balance this equation. Most of these kinds of equations are double displacement reactions: AX + BY 6 AY + BX 2. For the total ionic equations
(iii)€€€€ Write an equation for the complete coustion of the alkane C11H24 (iv)€€€ Write an equation for the incomplete coustion of C 11 H 24 to produce carbon and€water only.
Spectator ions can be left out of the equation, giving Fe (s) + Cu 2+ (aq) Fe 2+ (aq) + Cu (s) This is the ionic equation for the reaction between iron and copper(II) sulfate. Iron is oxidised and copper is reduced. Similarly, the reaction between tin and lead
Write an equation for the fermentation of glucose (C 6 H 12 O 6) to form butan-1- ol, carbon dioxide and water only. State one condition necessary to ensure the complete coustion of a fuel in air. Write an equation for the complete coustion of butan-1-ol and

Molecular, Total Ionic, and Net Ionic Equations Molecular equations are balanced equations that show all soluble aqueous ionic substances as un-dissociated compounds. Remeer to balance the equation and use phase labels. Total ionic equations show all
(see complete coustion), then some or all of the carbon turns to carbon monoxide. This happens with any hydrocarbon. We shall take methane as an example. During incomplete coustion methane gas burns with a yellow flame (unlike the clear blue flame ).
First it is important to know the molecular formula for pentane and the products of the coustion reaction so that we can write the unbalanced equation. From the prefix ''pent'' we know that the hydrocarbon contains 5 carbons and because this is an alkane we can use the C n H 2n+2 general formula to work out the molecular formula of pentane as C 5 H 12 .
