4.1 Writing and Balancing Chemical Equations – Chemistry

The chemical equation described in section 4.1 is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. This is a requirement the equation must satisfy to be consistent with the law of conservation of matter. Get price

Chemical Reactions and Chemical Equations

2015/7/7The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry – the equation.

How to Calculate Reactions at Supports?

It involves calculating the reaction forces at the supports (supports A and B in the below example) due to the forces acting on the beam. You will need to know this to progress through and calculate bending moment diagrams (BMDs) and shear force diagrams (SFDs); an important part of your statics and structural college/university courses.

Temperature Dependence of the Rate of a Reaction:

While cooking, if we keep the gas on low temperature, the food cooks slowly. But when we increase the temperature to its maximum, the food cooks quickly. Therefore, temperature increases the rate of a reaction. This dependence of rate on temperature can be explained by Arrhenius equation. Get price

The C1V1 = C2V2 Equation Explained

Calculate the amount of 10 μM forward primer solution to add to a PCR reaction (25 μL total reaction) to make a final concentration of 0.4 μM forward primer in the reaction. So by using the C 1 V 1 = C 2 V 2 equation, we need to first rearrange this to work out V 1 (the initial volume of primer we need to add). Get price

Zero, First and Second Order Reactions

The order of the above reaction is equal to (m + n). These powers or exponents, i.e., m and n have no relation to the stoichiometric coefficients a and b of the balanced chemical equation. Order of the reaction with respect to A is m and that with respect to B is n Get price
