To measure the electrolytes in this science project, you will use a multimeter. A multimeter is an electronic device that measures voltage, current, and resistance. You can learn more about these terms in the Science Buddies Electronics Primer.
The total mole number of solutes will not change. So it is 25 * 10^-3 *4.525 mole. And the final volume is 25+112 = 137 mL. So the resulting concentration is mole number / volume=0.8257 M.
Answer: When a combination reaction occurs between a metal and a non-metal the product is an ionic solid.
Explanation: Another hint(s): When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide. This specific combination reaction produces the bright flame generated by flares.
To solve this you need to find the radius of the bigger cylinder so you have to solve the equation 36π=
π(9). When you solve it you end up with a radius of 2 in which you multiply by 1.2 which gives you the radius of the new cylinder which is 2.4. With the new radius you simply find the volume of the bigger cylinder which is 51.94π
.
