Why are oxidation numbers important when writing a chemical formula?
Oxidation numbers help determine the ratio of elements in a compound, which is essential for writing a correct chemical formula. They allow you to balance the charges of the ions or atoms present to ensure overall charge neutrality in the compound. Additionally, oxidation numbers give insight into the transfer of electrons during chemical reactions.
What gas dissolved in water that acts as a bleaching agent present in bleaching solution?
Chlorine gas dissolves in water to form a bleaching agent known as hypochlorous acid which is present in bleaching solutions.
What is the present tense of determined?
I/you/we/they determine. He/she/it determines. The present participle is determining.
What useful functions do oxidation numbers serve?
Oxidation numbers help determine the amount of electrons an atom has gained, lost, or shared in a compound. They are useful for balancing chemical equations, predicting the reactivity of elements, and identifying the type of chemical bond present (ionic or covalent). Additionally, oxidation numbers play a crucial role in understanding redox reactions and determining the oxidation state of elements in compounds.
What is the substance present in larger amount in a mixture?
A mixture is made up of the solvent and the solute. In an unsaturated mixture the solvent is in greater amount.
Does oxygen have to be present for an oxidation-reduction reaction to take place?
nope
Does removing oxygen always prevent an oxidation recreation?
Removing oxygen does prevent oxidation from occurring since oxidation is a chemical reaction that involves the gain of oxygen by a substance. Without oxygen present, oxidation cannot take place.
Assume you had a mixture of solid na2co3 and nacl could you use only h2so4 to determine whether or not na2co3 was present explain?
Yes, you could use H2SO4 to determine the presence of Na2CO3 in the mixture. When H2SO4 is added to the mixture, effervescence will be observed due to the reaction between Na2CO3 and H2SO4, producing CO2 gas. This effervescence confirms the presence of Na2CO3 in the mixture.
How does corrosion?
Rust? It's oxidation. More likely to occur with moisture present.
How can Dalton's law be applied in everyday life?
Dalton's Law of Partial Pressures is used everyday to determine how much of one gas is present in a mixture of gases.....maybe not YOUR "everyday" but someones
What is two kinds of mixture?
HOMOGENEOUS MIXTURE: A homogeneous mixture is a type of mixture in which the composition is uniformHETEROGENEOUS MIXTURE: A heterogeneous mixture is a type of mixture in which the components can easily be identified, as there are two or more phases present
Is hot tea a homogeneous mixture?
If there are no tea leaves in the mixture, then it is a homogeneous mixture, or solution. If there are tea leaves present, then it would be a heterogeneous mixture.
