Each mole of substance contains 6.02 x <span>1023</span> component parts, in this case water molecules.
If you have 2.3 moles of water you will have 2.3 x 6.02 x <span>1023</span> which is 1.3846 x <span>1024</span> molecules.
Each molecule contains 2 hydrogen atoms, so the total number of hydrogen atoms in 2.3 moles of water will be 2 x 1.3846 x <span>1024</span> = 2.7692 x <span>1024</span>.
Please mark brainliest, thanks :)
Answer is: n-octane.
Octane is the straight-chain alkane (an acyclic saturated hydrocarbon) with eight carbon atoms.
Carbons in octane have sp3 hybridization (carbon’s 2s and three 2p orbitals combine into four identical sp3 orbitals).
Orbitals in sp3 hybridization have a tetrahedral arrangement and form single (sigma) bonds.
Burning octane fuel is very fast chemical reaction, it happens in immediately.
Main products of the combustion of fossil fuels are carbon(IV) oxide and water.
Chemical reaction: C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O; ΔH = -5500 kJ/mol.
Answer:
The nitrogen cycle is a cycle by which the nitrogen is converted into forms which are utilized by the living organisms and these forms circulates among the atmosphere, biosphere, and marine ecosystem. The conversion of nitrogen is through biological and physical processes.
Nitrogen Fixation is the first step in nitrogen cycle. It involves the conversion of atmospheric nitrogen into ammonia. This is done by bacteria like Azotobacter and Rhizobium.
Assimilation involves the absorption of ammonia by the plants from the soil.
Ammonification is the process by which the dead organic remains of plants and animals are decomposed by the soil bacteria to produce ammonia.
Nitrification is the process in which the ammonia is converted into nitrates by the soil bacteria Nitrosomonas and Nitrococcus. The nitrates are again converted into nitrites by the bacteria Nitrobacter.
On the basis of above description, the following is the match of steps of the nitrogen cycle.
A. Nitrification - bacteria convert nitrates into nitrogen gas.
D. Assimilation - plants and animals take in and use nitrogen compounds.
E. Denitrification - bacteria break down waste products and return nitrogen to the soil.
B. Nitrogen fixation - bacteria convert atmospheric nitrogen to ammonia.
C. Ammonification - bacteria convert ammonia to nitrites and nitrates
Well usually a tornado forms when hot air and cold air come together and in the south, but since the weather is cold and they live by mountains a tornado would not happen.
A hurricane happens by the ocean.
I believe the answer would be a rainstorm. <span />
