Answer:
Heat deals more with thermal energy whereas temperature deals with molecular kinetic energy.
Answer:
<em>The branch of natural science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alternations in the constitution of their molecules is chemistry.</em>
Explanation:
Answer:
Required number of moles of ideal gas is 0.877 moles.
Explanation:
Pressure (P) = 0.850 atm
Temperature (T) = 295 K
Volume (V) = 25 ltr
Universal gas constant (R) = 0.0821
no of moles (n) = ?
we have the ideal gas equation as:
PV= nRT
or, 0.850× 25 = n × 0.0821 × 295
or, n = 0.877 moles
Hence the required number of moles of an ideal gas is 0.877 moles.
As you have not provided the options, still we can figure out the answer by understanding the key difference between saturated and unsaturated hydrocarbons.
SATURATED HYDROCARBONS are those hydrocarbons which only consist of a carbon carbon single bonds. All the bonds are sigma there are no pi bonds at all. Examples are shown below.
While, UNSATURATED HYDROCARBONS are those hydrocarbons which may contain either a double bond or triple bonds or both of them between the carbon atoms as shown below.
Answer: An acid is defined with having more [H₃O+] ions, and a base is defined with having more [OH-] ions. On the pH scale, an acid has a lower pH and a base has a higher pH. With this being said, the lower the pH, the more [H₃O+] ions are present and the higher the pH, the more [OH-] ions are present.
