How do you plot the equation v=3m/s+(2m/s^2)(t) from t=0s to t= 10sec Prove that y = In(d(x-vt)) is a solution of the standard wave equation, where d is a constant. What is the coefficient of restitution? What are the chemical formulas of: (a) baking soda? (b) vineg...
The pH meter must be switched on in the standard solution (KCl solution of 3M).When the switchon and switch-off are stopped at the same number for two consecutive times, record the number as A, and then record the measured number as B. The figure obtained by using b× (7/a) is th...
What problem would be encountered if you tried to dissolve Ag2O with an HCl solution? Precipitation Reactions A precipitation reaction is a type of reaction that occurs when two ions react and form an insoluble salt. This type of reaction is usually a double displacement rea...
Which solution has the greatest number of ions? 2 L of 1.5M Na_3PO_4 3 L of 1.5M NaCl 2 L of 2M KF 1 L of 3M Na_2SO_4 What is the oxidation number of S in Fe2(SO4) 3? What charges an atom? In chemistry, what is a formula used to represent?
Then, compute for the mass of NaCl in the solution and number of moles of a 1 kg water. The formula is given below for mass percent and mole fraction respectively % mass= mass NaCl H2O×100% xNaCl= mole NaCl mole NaCl+ mole H2O...
/total mass of solution If concentration is 0.3M CaCl2, that means the following: In 1000ml of solution there is 0.3mol of CaCl2 In 1000ml of solution there is 0.3 111 g of CaCl2 We can also convert 1000ml of solution into g by multiplying the volume with density of the solut...
Ringer's solution is a solution of several salts dissolved in water. It is used as an isotonic solution relative to the body fluids of the animal into consideration. Usually, it contains {eq}NaCl {/eq}, {eq}KCL {/eq}, {eq}CaCl_2 {/eq},...
A common example is the solution, which follows a solute-solvent relationship. The solvent is usually a liquid and in excess, while the solute is a substance that is dissolved in the solvent. The abundance of the solute in the prepared solution is defined as a concentration, not a single ...
How would you prepare a 500 mL of 0.020 M KMnO_4 solution? A 20.0 mL sample of H2C2O4 was titrated with 20.0 mL of 0.100 M KMnO4. What is the molarity of H2C2O4? 2KMnO4 + 5H2C2O4 + 6HCl = 2MnCl2 + 2KCl + 8H2O + 10CO2 (A) 0.0500 M (B) 0...
