Hey there!:
Volume in mL:
3.5 * 1000 = 3500 mL
density = 1.2 g/mL
Therefore:
D = m / V
1.2 = m / 3.5
m = 1.2 * 3.5
m = 4.2 g
hope this helps!
Answer:
The answer to your question is:
Explanation:
1) the mass of the products is greater than the reactants
The mass does not affect that a reaction occurs or not because if there is less quantity of a reactant only will react the proportion. This answer is incorrect.
2) the products are more stable than the reactants This answer is correct, if products are more stable than reactants, then the reaction happens.
3) the products are the same stability as the reactants The both products and reactants have the same stability, the reaction is reversible, then this answer is incorrect.
4)the products are less stable than the reactants if products are less stable than reactants, the reaction does not happen. This option is incorrect.
Answer:
hey. I remember learning about this and asking my teacher why the heck would you think about all that instead of just eating the food XD.....
but the Heat from the burner warms the pan by conduction. The liquid soup is warmed by convection currents. ... Metal is a good conductor of heat. Theheat energy moves from the hot liquid through the spoon by conduction.
If you're holding the apple at your waist, lift it to your mouth.
Potential energy relative to any level is proportional to its height
above that level. Increase that height, and you've increased the
potential energy.
Since energy is conserved ... it never magically appears or
disappears ... you need to tell where that extra energy for the
apple came from.
It's exactly the work you did ... the force of your muscles acting
through the distance you raised the apple ... that became the
additional potential energy that the apple gained.
