Answer:
Answer B is correct. Paying off your credit card bill will reduce the amount of debt you have and improve your credit score. Closing old credit cards only works if they are unused. As savings accounts are not included in a credit report, opening a new savings account will not have an effect, either negative or positive, on your credit score. Using up your credit limit will have the negative effect of lowering your credit score.

Answer:
A. Alternating single and double bonds
Explanation:
Hydrocarbons i.e. hydrogen and carbon containing compounds, are grouped into two namely: aliphatic and aromatic hydrocarbons. Aliphatic hydrocarbons contains straight or branched chains of carbon and hydrogen atoms in their structure e.g. alkanes, alkenes etc.
On the other hand, aromatic hydrocarbons are cyclic hydrocarbons containing one or more cyclic rings. The benzene ring is the basis of all aromatic hydrocarbons and one characteristics of benzene is that it possesses an alternating single (-) and double bonds (=) in their structure.
Since benzene is a building constituent of aromatic hydrocarbons, an "alternating single and double bond" is a characteristics of aromatic hydrocarbons.
Just like there are different levels and branches of math they are different branches of chemistry like in math different jobs require different types of levels of chemistry and math. Do you learn different things in the groups.
Answer:
092) Icosane
093) Ethene
Explanation:
092) The given compounds are;
Decane C₁₀H₂₂; Viscosity = 0.850 mPa·s (25°C)
Ethene C₂H₄ (gas); Viscocity ≈ 0.01038 m
Icosane C₂₀H₄₂; Solid at room temperature
Methane CH₄; gas at room temperature
The viscosity of the given carbon and hydrogen compounds is observed to increase with their molar masses
Therefore, icosane, which is a solid at room temperature, has the highest viscosity (resistance to deformation) out of the given compounds
093) Polymers are made from monomer alkene units, therefore, ethene, which is the only alkene among the given compounds can be used to produce a polymer
Polyethene is formed by the polymerization of ethene whereby molecules of ethene are joined together to form poly(ethene)
