I'm pretty certain the answer is 2) because fluorine is a diatomic gas meaning it travels with 2 molecules (simplified). It is a gas so molecules should also be spread out so the answer cannot be 3) or 4).
Hope this helps! :)
The moles of carbon that are in the sample of 21.45 moles of heptane(C₇H₁₆) is 150.15 moles
<u><em>calculation</em></u>
moles of carbon = moles of heptane × number of C atom
number of C atom in heptane = 1 ×7 = 7 atoms
moles is therefore = 21.45 moles × 7 =150.15 moles
I don’t understand wha u just said but thanks for the points
Answer: (D) concentration of the products remains constant.
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
Thus at chemical equilibrium, the amount of product and reactant remains constant because the rates of the forward and reverse reactions are equal.
A chemical equilibrium is dynamic in nature forward and backward reactions continue for indefinite time and never stops.
Answer:
Rocks are the aggregate of minerals. There are three distinct categories of rocks, namely the sedimentary, metamorphic and the igneous rocks.
- The sedimentary rocks are formed from the deposition, compaction, and lithification of soft sediments that are transported from one place to another by the agents such as wind, water, and ice. For example, Sandstone and Shale.
- The metamorphic rocks are derived from the previously existing sedimentary, igneous or other metamorphic rocks, due to the influence of extremely high pressure as well as temperature conditions. For example, Quartzite and Marble.
- The igneous rocks are those rocks that are formed from the cooling and crystallization of magma. For example, Granite and Diorite.
All these three types of rocks are formed by different processes and their mode of origins are also different.
