What else can I help you with?
What data will you need to determine whether a chemical reaction occurred?
To determine whether a chemical reaction occurred, you will need data such as changes in temperature, formation of new substances, release of gas, and changes in color or odor.
Sugar crystals are separated from a sugar syrup by evaporation of water is a chemical reaction or physical reaction?
The separation of sugar crystals from a sugar syrup by evaporating water is a physical process, not a chemical reaction. This is because no new substances are formed during the process—the sugar molecules remain the same whether in the syrup or as crystals.
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
What does the enthaply of reaction measure?
The enthalpy of reaction measures the amount of heat absorbed or released during a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (heat is released) or endothermic (heat is absorbed).
What is the most important quiestion to ask to determine whether a change is physical or chemical?
The most important question to ask is whether the change results in a new substance being formed. Physical changes involve a change in appearance, state, or size of a substance without forming a new substance. Chemical changes involve a reaction that results in the formation of new substances with different chemical properties.
What data will you need to determine whether a chemical reaction occurred?
To determine whether a chemical reaction occurred, you will need data such as changes in temperature, formation of new substances, release of gas, and changes in color or odor.
Is reacting with vinegar a physical or chemical property?
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
two information not provided by a chemical equation?
Symbols and formulae of all the substances involved in a particular reaction. Number of atoms/molecules of the reactants and products formed. Whether a particular reaction is actually feasible or not.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
Sugar crystals are separated from a sugar syrup by evaporation of water is a chemical reaction or physical reaction?
The separation of sugar crystals from a sugar syrup by evaporating water is a physical process, not a chemical reaction. This is because no new substances are formed during the process—the sugar molecules remain the same whether in the syrup or as crystals.
Explain how you can tell whether a chemical reaction has taken place?
A chemical change or reaction happens if new substances are formed. there may be a change in temperature so the reaction mixture may heat up or cool down. it also might change colour, give off bubbles of gas or fumes and you also might hear fizzing or a gas might explode.
What always results in a chemical reaction?
A chemical reaction always occurs when the bonds between atoms in one or more substances are broken or formed, leading to the creation of new substances with different chemical properties. This process involves the rearrangement of atoms and the release or absorption of energy.
3 things you could see if a chemical reaction occurs?
Things to check whether a chem. reaction is occurring or not:-Evolution of gasChange in temperatureFormation of precipitateChange in colour of solution or substance
What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).

Which term identifies a type of chemical reaction?
There are more than one type of chemical reaction. -liquid -solid It's when two objects or liquids mix together causing a chemical reaction. By: Sarah P. Stewart
