Answer:
b) Product
c) Combustion
c) speeds up the rate of reaction
Explanation:
the substance produced by a chemical reaction is called a product (b)
Combustion (c) reactions are involving oxygen and "another substance" [and hydrocarbons] to <em>produce carbon dioxide and water</em>.
A <em>catalyst </em>acts to speed up the rate of a reaction (c)
<em> > note </em><em>how it "speeds up" reaction: , it [a catalyst] lowers the pressure or temperature needed to start one--but it isn't used/consumed in the reaction</em>
So, the answers are: b, c, c
hope this helps!!
1) Based on the crystal field strength, Cl ligand would give the longest d-d transition when complexed with Ti(III). as this is the weak field igand and would cause minimum splitting of d orbitals.
Answer:
CHCI₃
Explanation:
Chloroform, IUPAC name, trichloromethane, is organic compound with the molecular formula CHCl₃. It is colorless and sweet-smelling liquid having high density which is produced on a large scale precursor of PTFE , and for various refrigerants .
Chloroform , is a powerful euphoriant , anxiolytic , anesthetic and sedative when inhaled or ingested .
Answer: Option (A) is the correct answer.
Explanation:
Condensation is defined as the process in which vapors or gaseous phase changes into liquid phase.
Freezing is the process in which liquid phase changes into solid phase.
Evaporation is the process in which liquid phase changes into vapors or gaseous phase.
Melting is the process in which solid phase changes into liquid phase.
Therefore, we can conclude that names for given phase changes A and B is that A is condensation and B is freezing.
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
