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.

Chemical reactions are used to produce organic molecules like morphine, oxycodone, and other opioids. Decide if each statement below is describing a covalent bond,an ionic bond, a hydrogen bond, or multiple bond types. Note: To complete the question and move on to the next one,you will need to drag one of the statements to more than one target! Drog each item on the left to its matching item on the right. Note that every item may not have a match, while some items may have more than one match. formed between oppositely charged atoms formed between a molecule with a partially positive hydrogen and another negatively charged atom found in a glass of water Methane (CH_(4)) has four of them." formed when two atoms share electrons formed when sodium (Na)transfers an electron to chloride (Cl)to make table salt (NaCl) covalent bond Methane (CH_(4)) has four of them. . ionic bond formed between oppositely charged atoms formed when sodium (Na)transfers an electron to chloride (Cl)to make table salt (NaCl) hydrogen bond formed between a molecule with a partially positive hydrogen and another negatively charged atom

In the extraction of aluminium from aluminium oxide by electrolysis the positive electrode is made of carbon and needs to be regularly replaced. Explain why.

27. The chemical reaction shown below takes place in a closed system. What is true about the system while the reaction occurs? 1 point The following diagram represents the reaction of methane with oxygen gas to form carbon dioxide and water. The total mass of the particles in the system stays the same. The total mass of the particles in the system decreases. The total mass of the particles in the system increases. The total number of particles in the system increases.

A teaspoon of salt is DISSOLVED into 100 grams of water and stirred until the sAM disappears. The mass of the liquid is now. less than 100g because the mass of the salt is taken away 100g(as before), because only the water remains [Any of these could be true more than 100g, because it now is a solution of water and salt
