Chemistry Homework Assistance
QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.
- Ionic bonds always occur between: Metal and non-metal atoms Metal atoms Non-metal atoms Noble gases
- Non-metal atoms form ions by: Gaining one or more electrons to form a negative ion Losing one or more electrons to form a negative ion Losing one or more electrons to form a positive ion Gaining one or more electrons to form a positive ion
- Use only the periodic table above to answer the following questions. a. Identify the remaining letters B-I choosing from the following terms: __ Elements with predictable valence electron numbers __ transitional elements __ lanthanides __ actinides __ Alkali metals __ Alkaline earth metals __ halogens __ noble gases
- What element of the fire triangle does a fire blanket remove? Choose the Gorrect option and select Submit Oxygen Fuel Heat
- (b) Covalent compounds such as hydrogen sulfide have low melting points and do not conduct electricity when motten Draw one line from each property to the explanation of the property. Property Low melling point Does not conduct electricity when molten of property Explanation Electrons are free to move There are no charged particles free to move lons are free to move Weak intermolecular forces of attraction Bonds are weak Bonds are strong
