Answer: The derivative of a constant term is always 0. So the acceleration of the body would be zero. Hence, the acceleration of a body moving with uniform velocity will always be zero.
Hope this helps :) :)
Answer:
Percentage lithium by mass in Lithium carbonate sample = 19.0%
Explanation:
Atomic mass of lithium = 7.0 g; atomic mass of Chlorine = 35.5 g; atomic mass of carbon = 12.0 g; atomic mass of oxygen = 16.0 g
Molar mass of lithium chloride, LiCl = 7 + 35.5 = 42.5 g
Percentage by mass of lithium in LiCl = (7/42.5) * 100% = 16.4 % aproximately 16%
Molar mass of lithium carbonate, Li₂CO₃ = 7 * 2 + 12 + 16 * 3 =74.0 g
Percentage by mass of lithium in Li₂CO₃ = (14/74) * 100% = 18.9 % approximately 19%
Mass of Lithium carbonate sample = 2 * 42.5 = 85.0 g
mass of lithium in 85.0 g Li₂CO₃ = 19% * 85.0 g = 16.15 g
Percentage by mass of lithium in 85.0 g Li₂CO₃ = (16.15/85.0) * 100 % = 19.0%
Percentage lithium by mass in Lithium carbonate sample = 19.0%
Answer:
metal atoms lose electrons to form positive ions (cations ) non-metal atoms gain electrons to form negative ions (anions )
i agree with this answer from the person above me: Augustlonley
Explanation:
*throws leaves in his face* Hey you wake up!!
When a reactant is removed based on a reaction at equilibrium, the condition favors the backward reaction. This obeys the Le Chatelier's principle which states that any disturbance in the system shall be dealt in a way that the system counters that disturbance.
Answer:
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Explanation:
Find:
Molar mass of H3PO4
Given;
Molar mass of H = 1.0079 g/mol
Molar mass of P = 30.974 g/mol
Molar mass of O = 15.999 g/mol
Computation:
Molar mass of H3PO4 = (1.0079)(3) + 30.974 + 15.999(4)
Molar mass of H3PO4 = 3.0237 + 30.974 + 63.996
Molar mass of H3PO4 = 97.9937
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
