The stoichiometric ratio shows the numerical relationship between reactants and products. It can be attained from a balanced chemical reaction. Through the stoichiometric ratio, we will be able to solv...
Question: How do you find n (number moles of electrons transfered inbthe reaction) to use in the formula G = -nFE? How do you find n (number moles of electrons transfered inbthe reaction) to use in the formula G = -nFE?Show transcribed image ...
If you don't know the concentrations of your initial solutions, calculate molarity by dividing the number of moles in a solute by the volume of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this...
A gas initially at 5.42 L, 1.65 atm, and 66 degrees C undergoes a change so that its final volume and temperature are 2.98 L and 31 degrees C. What is its final pressure? Assume the number of moles re Fluorine exerts a pressure of 1.21 atm. When the pressure is changed to ...
A neutralization equation is a chemical reaction that involves the combination of a strong acid and a strong base. The products of such a reaction are typically water and a salt. It is useful to know how to solve neutralization equations because they are
Compare that to the daily VO2 value from the previous question. By what factor does O2 (or energy) consumption increase during exercise? There are 2 steps to solve this one. Solution Share Step 1 Here is the step by step solution of ...
To solve the problem of finding the grams of ethanol in a 1.54 molal solution with 2500 grams of water as the solvent, we can follow these steps: Step 1: Understand the definition of molalityMolality (m) is defined as the number of moles of solute per kilogram of solvent. The formula ...
Grams to Moles Step 1 Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Step 2 Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the...
You pour 12 grams of salt (NaCl) into a beaker containing 20 ounces of water. What is the molarity of salt in the solution? You can solve this problem in three easy steps: 1. Find the Number of Moles of Salt Rounding to one decimal place, the mass of one mole of sodium (Na) is...
When to Call in the Pros What are Voles? Not to be confused with moles, voles are rodents but they are neither blind nor deaf. Also dubbed “meadow mice” and “field mice” (although the latter is a totally different animal), voles feed on plants, while moles eat insects, earthworms,...
