Reaction calculations
WebThe reaction force R is at right angles to the ramp. The box is not accelerating, so the forces are in balance: The 100 kg mass creates a downward force due to Gravity: W = 100 kg × 9.81 m/s 2 = 981 N . We can use SOHCAHTOA to solve the triangle. Friction f: sin(20°) = f/981 N. f = sin(20°) × 981 N = 336 N. Reaction N: cos(20°) = R/981 N Web(a) Calculate the cell potential, assuming standard conditions. (b) Write the net ionic equation for the reaction occurring in the cell. (c) Which electrode is the anode and which is the cathode? (d) If [Ag+] is 0.10 M, and [Fe2+] and [Fe3+] are both 1.0 M, what is the cell potential? Is the net cell reaction still that used in part (a)?

WebMole ratios are used as conversion factors between products and reactants in stoichiometry calculations. For example, in the reaction . 2H₂(g) + O₂(g) → 2H₂O(g) The mole ratio between O₂ and H₂O is #(1 mol O₂)/(2 mol H₂O)#. ... To calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant. ... WebThe order of reaction determines the relationship between the rate of reaction and the concentration of reactants or products. It is the power to which a concentration is raised in the rate law equation. For example, for the reaction xA + yB ---> products, the rate law equation will be as follows: Rate = k [A]^a . [B]^b.
WebTranscript When a weak acid and a weak base are mixed, they come to an equilibrium state represented by the following equation: HA (aq) + B (aq) ⇌ A⁻ (aq) + HB⁺ (aq).
WebTo find the amounts of each reagent consumed or product consumed in the reaction, use the smallest value from before to perform the necessary stoichiometric calculations by multiplying the value, by the coefficient and molar mass of each substance: Al = 0.383 mol * 4 * 26.981 g/mol = 41.334892g (consumed) 100g - 41.334892g = 58.67g excess north cyprus paradiseWebTwo-dimensional transition metal dichalcogenides (2D TMDCs) show promise as potential inexpensive electrocatalysts for hydrogen evolution reaction (HER).
