okay, this doesnt make sense to me, when studying equilibrium, we added Nacl and HCl the BCE is

NaCl + Hcl <-----> Nah and Cl 2 ?????? <--correct?

Is Cl2 a diatomic molecule or is it ionized in the water.

how do you find the critical points of an equation if it has both x and y variables. For instance.

f(x,y) = 3x - (x^3) - 2(y^2)+(y^4)

I just don't know how to get the critical points because when you take the derivative and split it up into x and y components, there is no way to get the value of the other component.

An electron of mass 9.11x10^-31 kg has an initial speed of 5.0x10^5 m/s. It travels in a straight line and its speed increases to 8.00x10^5 m/s ina distance of 10cm. Assuming its acceleration is constant, determine the force exerted on the electron. And what is the ratio of this force to the weight of the electron?

To model a spacecraft, a toy engine is securely fastened to a large puck, which can glide with negligible friction over a horizontal furface, taken as teh xy plane. The 7.0kg puck has a velocity of 2.00i m/s at one instant. Eight seconds later, its velocity is to be (5.00i + 7.00j)m/s. Assuming the rocket engine exerts a constant total horizontal force, find the components of the force. Find its magniutde.

Some claim that these features are the result of vast lava plains, filling in a swarm of huge craters. Yet it is a known fact that such lava plains are an impossibility, and the proposed craters are much too large to be possible. In addition, much like similar features on Mars and Mercury (the Argyre and Caloris Basins,) the Moon's circular Maria are surrounded by mountains uncharacteristic of craters. As if this weren't enough, many of these features also have antipodes which show swirls, "Weird Terrain" (Mercury) and even traces of polar magnetism.
