hope this helps!! have an amazing day <3
Answer:
1000g
Explanation:because the higher mass takes up heat.
I think the form energy that is found in the ice cubes would be thermal energy. It <span> is the </span>energy<span> that comes from heat. Since all things tend to go towards equilibrium, the ice cubes dissipates heat to equilibriate with the environment.</span>
Answer: D.) 25.9%
Explanation:
Dinitrogen pentoxide chemical formular : N2O5
Calculating the molar mass of N2O5
Atomic mass of nitrogen(N) = 14
Atomic mass of oxygen(O) = 16
Therefore molar mass :
N2O5 = (2 × 14) + (5 × 16) = 28 + 80 = 108g/mol
Percentage amount of elements in N205:
NITROGEN (N) :
(Mass of nitrogen / molar mass of N2O5) × 100%
MASS OF NITROGEN = (N2) = 2 × 14 = 28
PERCENT OF NITROGEN : (28/108) × 100%
0.259259 × 100%
= 25.925%
= 25.9%
