Answer: 2. Heat flows from faster molecules to slower molecules when they collide.
Explanation: Hope this helped! :)
V = 28,42 mL = 0,02 L
molar mass C3H6O = 58
n C3H6O
= V / 22,4
= 0,02 / 22,4
= 0,0009 mol
mass
= n x molar mass
= 0,0009 x 58
= 0,0522 gr
Answer:
Explanation:
Selenium is a chemical element with the symbol Se and atomic number 34.
...
Selenium
Melting point 494 K (221 °C, 430 °F)
Boiling point 958 K (685 °C, 1265 °F)
Density (near r.t. ) gray: 4.81 g/cm3 alpha: 4.39 g/cm3 vitreous: 4.28 g/cm3
when liquid (at m.p. ) 3.99 g/cm3
False; animals breathe in oxygen and they produce carbon dioxide when they breathe out, and plants breathe in that carbon dioxide that the animals produce, and with that the plants create oxygen
They basically just swap oxygen for CO2, or CO2 for oxygen! So the answer is false because they DO depend on each other for the use of Oxygen and Carbon dioxide! Hope this helped :)
Answer:
it will affect the mass by changing in pressure will affect the volume (and therefore density) of gases, but will not noticeably affect the volume (or density) of solids and liquids. For gases: An increase in pressure leads to a decrease in volume and an increase in density. A decrease in pressure leads to an increase in volume and an decrease in density.
