3. If the reaction reaches equilibrium and then the reaction vessel is heated, how will the reaction respond to re-establish equilibrium? A) It would drive it towards reactants B) It would drive it towards products C) The reaction would remain unchanged

Find the indicated area under the curve of the standard normal distribution; then convert it to a percentage and fill in the blank. About of the area is between \( z=-3.5 \) and \( z=3.5 \) (or within 3.5 standard deviations of the mean). About \( \square \% \) of the area is between \( z=-3.5 \) and \( z=3.5 \) (or within 3.5 standard deviations of the mean). (Round to two decimal places as needed.)

How many kilograms are there in 2885 g ?

A body of mass 9 kg moves in a (counterclockwise) circular path of radius 5 meters, making one revolution every 9 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component. A. Compute the centripetal force acting on the body. B. Compute the magnitude of that force. Note: Use exact forms or at least 4 significant digits in your answers. Submit answer

\( \frac { \sin 4 x \cdot \cos 2 x - 2 \cos 4 x \cdot \sin x \cdot \cos x } { \tan 2 x } = \cos ^ { 2 } x - \sin ^ { 2 } x \)

б) \( 21 x^{3} y: \frac{7 x^{3} y^{2}}{3} \);
