Fill in the coefficient numbers on the final balanced chemical equations below a. HCl + NaOH à NaCl + H20

b. C2H6O + O2 à CO2 + H2O

. If the equations can be simplified (by dividing all coefficients by the same number), please do so.

Write a question about how changing temperature affects the gas inside the sports ball

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
