Si un electrón ubicado a cierta distancia de una partícula cargada experimenta una fuerza de atracción de cierta magnitud, ¿cómo será la magnitud de la fuerza respecto a este valor si duplicamos la distancia?

What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

What is the work done by the electric force to move a 1 c charge from a to b?
