Answer:
Because the molecules of the mixture would be compact or bond together at room temperature. In this case, both gases will condense to form water (or ice, if the room temperature is prolonged) and such droplets of water will not cause a balloon to spontaneously explode at room temperature.
Explanation:
A mixture of hydrogen and oxygen will form water. Recall that the chemical formula for water is H₂O, where H represents Hydrogen and O represents Oxygen.
A balloon is a light (not thick) solid substance with a thin membrane when blown or filled with some elements or gases.
Room Temperature means cool or cold temperature. You already know that generally at room temperature, the molecules of any substance will stick together or will become less mobile (less spontaneous).
In this case, hydrogen gas and oxygen gas will go through a process called condensation - to form water - and then through the process called freezing - to form ice.
At room temperature, the gases will first change state (state of matter) from gaseous to liquid and then from liquid to solid.
This is why the balloon will NOT spontaneously explode.
Answer:
n = 0.413moles (3 sig-figs).
Explanation:
From definition of molarity, solve for moles and substitute given data.
Molarity(M) = Moles Solute(n)/Volume of Solution in Liters(V)
M = n/V => n = M·V => 0.330moles/Liter x 1.25Liters = 0.4125moles ≅ 0.413moles (3 sig-figs).
Answer:
Mitochondria
Explanation:
Mitochondria are organelles whose membranes are specialized for aerobic respiration.
Carbon has the ability to form multiple bonds because it has four valence electrons. Having four valence electrons means that carbon has a lot of space to form bonds with other atoms, or multiple bonds, in order to reach the full octet.
Hope this helps!! :)
CH4 and PH3 are both covalent since they are composed both of non-metals.
<span>
CH4 is non- polar because of </span> London forces and<span> has a geometry of tetrahedral PH3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (IMF) . Since PH3 is polar, it has a stronger IMF </span>
