If you wanted to find a sample of fermium,which has an atomic mass of 100 I would look deep under the earth
The correct answer is this one: "The amount of energy before and after the explosion depends on the type of reaction." The energy involved in an explosion is that t<span>he amount of energy before and after the explosion depends on the type of reaction, how strong and how weak; how destructive or less destructive.</span>
No, the distance from the first stop to the schools and the average speed is required.
Answer:
Exothermic reaction
Explanation:
Consider the reaction
A + B ⟶ C
If energy is released, the product C is at a lower potential energy level than the reactants A and B (see diagram).
Conversely, the reactants A and B are at a higher energy level than the product.
B is wrong. In an endothermic reaction, the reactants A and B are at a lower energy level than the product.
C and D are both wrong. Both types of reaction can be exo- or endothermic.
Answer:
N= PV/RT (temperature in kelvin); ( r is .0821 when pressure is in atm & r is 8.314 when pressure is in Kpa)
2.00 = P x 10.0/ .0821 x 300
after solving i got 4.926 atm
