chemical properties can be what
there's 2 types what is 2 types of chemical properties ?
Chemical reaction - The chemical reactions are classified into different classes depending upon the type of chemical changes take place these reactions are as follows:
Combination reaction
Combination reaction - A reaction in which two are more reactance combined to form a single product is call combination reaction
calcium oxide reacts vigorously with water to form calcium hydroxide the reaction is highly exothermic a lot of heat is produced during the reactionCaO(s) + H2O(l) -------------- CH3OH(l)Decomposition Reaction
Decomposition reaction - aur reaction in which a single reactant breakdown to form two or more products is known as decomposition reaction this reaction is opposite to combination reaction on the basis of the form of energy required for the reaction this reaction of three types
thermal decomposition this reaction use the energy in the form of heat for the decomposition of reactantElectrolysis these reactions involves the use of electrical energy for the decomposition of the reactant moleculesPhotolysis these reactions involved the use of light energy for the purpose of decompositionDisplacement reaction
Displacement Reaction - when a more reactive element displays less reactive element from its compound it is called displacement reaction.This is of types.
Single displacement reaction - it is a type of chemical reaction where an element reacts with the compound and takes the place of another element in that compound is called single displacement Zn + cuso4 --------- ZnSO4 + cuDouble displacement reaction - the reaction in which two different oils or group of atom in the reactant molecules are displaced by each other is called double displacement reaction it is also called precipitation reaction as precipitate is produced in such reactionsOxidation and reduction
Oxidation - it is the process in which oxygen is added to a substance or hydrogen is removed from a substance
Reduction - it is the process in which oxygen is removed from a substance or hydrogen is added to a substance
Redox reaction - these are the reactions in which oxidation and reduction takes place simultaneously or call redox reaction
Endothermic and Exothermic
Endothermic - the reaction which are a complaint by the evolution of heat are called exothermic reaction all the reaction in which heat is released along with the formation of product are called exothermic reaction
Endothermic - the reaction which occur by the absorption of heat energy either in the form of light electricity are called endothermic reaction

How to we know how many neutrons are in the atoms we draw models for ? (We represent average atoms, not ions or isotopes)
Answer:
Atoms is the smallest unit of a chemical element and consist of three main components protons, neutrons, and electrons.
The number of a neutron is based on the difference between the mass number of the atom (M) and the atomic number (Z). every isotope of an element has a different number of neutron.
But in a neutral atom or average atom, the number of neutrons is equal to the number of protons and the number of electron.
Example of the number of neutrons in an average atom: In Nitrogen-14, the atomic number and the number of protons is 7, it means the number of neutrons will also 7.

The volume of water in a transfer pipette is 15.23 ml. A 6.7 mL
volume of water was then transferred out. Considering
significant figures, what is the new volume?
Answer:
The new volume of water in the pipette is 8.53 mL
Explanation:
The given information are;
The initial volume of water in the transfer pipette = 15.23 mL
The amount of water transferred from the pipette = 6.7 mL
The new volume of water in the transfer pipette is given as follows;
New volume of water in the pipette = Initial volume of water in the pipette - Volume of water transferred out
Therefore, we have;
New volume of water in the pipette = 15.23 mL - 6.7 mL = 8.53 mL
The new volume of water in the pipette = 8.53 mL
Answer:
8.5
Explanation:
15.23 - 6.7 = 8.53
The correct amount of sig figs would make the answer 8.5

Explain the general increasing trend in the first
ionization energies of the period 2 elements,
Li to Ne
Answer:
The general trend is for ionisation energies to increase across a period. In the whole of period 2, the outer electrons are in 2-level orbitals - 2s or 2p. ... That causes greater attraction between the nucleus and the electrons and so increases the ionisation energies.

Which of the following are considered pure substances?
element
compound
homogeneous mixture
heterogeneous mixture
Element and compound both are considered as pure substances.
Thus, both option 1 and 2 are correct.
What is a pure substance?Pure substances are defined as materials with a consistent chemical composition that cannot be physically separated through the use of techniques like filtration, evaporation, etc.
Anything that is made up of the same atom or molecule throughout is a pure substance. Everything else is a mixture.
Since elements are not physically or chemically broken down to generate simple, tiny entities like zinc, elements and compounds are pure substances. Furthermore, pure substances like water are combined to create compounds.
Both homogeneous and heterogeneous mixtures are not pure substances since they lack predetermined ratios and proportions, making it difficult to identify their exact composition.
Pure substances include sodium, water, a copper wire, an aluminum foil, etc.
Thus, elements and compounds both are categorised as pure substances.

The phrase “the danger is in the dose” is sometimes used when describing poisonous (toxic) chemicals. What does this mean?
The phrase “the danger is in the dose” means that sometimes it contains toxic chemicals too.
Poisonous (toxic) chemicals:The inorganic chemicals most commonly responsible for poisonings in the United States are cyanide, mercury, arsenic, and lead. While the last three often appear in chemical forms that are quite harmless, it is the soluble salts of the substances that are poisons. Cyanide is a dangerous substance in any form. Overdoses can happen at many opioid dose levels. For example, for instance if a patient drinks alcohol while on the medications, loses track of when they last took a dose, or takes more than the prescribed dose to handle a flare-up of pain.
Thus, we can say overdose can be the danger in the dose.
