Among the different types of scientific knowledge, are likely to be modified or discarded most frequently. long ago, in the 1600s, scientists discarded the phlogiston theory because .

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.

If a simple machine aduces the strength of a force, what must be increased? the speed of the input force the work the simple machine performs the size of the simple machine the distance over which the force is applied
