Is reacting with oxygen a physical property of hydrogen?
No, reacting with oxygen is a chemical property, not a physical property, of hydrogen. Physical properties are characteristics that can be observed without changing the substance's chemical composition, such as density or color. Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
Is mixing hydrogen and oxygen together a chemical change or a physical change?
Just the mixing of hydrogen and oxygen isn't a change at all. But if they react under specific conditions, you have a chemical change. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O
Is fertilizing a lawn a chemical or physical change?
chemical change
Is adding HCl to Mg and physical or chemical change?
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)
If two chemicals are mixed together is it a physical change?
No, mixing two chemicals together is a physical change because the substances retain their original chemical properties. The chemical composition remains the same even though they are physically combined.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.

Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
Is spilling of acid on a cloth a physical or chemical change?
It is a chemical change only if this acid react with the cloth.
Is failure to react a physical or chemical?
Failure to react can be both physical and chemical. Physical failure to react usually refers to a lack of mixing or contact between reactants, while chemical failure to react can occur when the required conditions for a reaction to take place are not met, such as proper temperature or presence of a catalyst.
Is mixing hydrogen and oxygen together a chemical change or a physical change?
Just the mixing of hydrogen and oxygen isn't a change at all. But if they react under specific conditions, you have a chemical change. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O
Is metal roasting a chemical or physical change?
The rusting of metal is a chemical change and not a physical change. This is because iron and water react to form a compound called iron oxide.
When sodium is put into waterit react forming sodium hydroxide and hydrogen is this physical change or chemical change?
That's most definitely a chemical change, because new forms of matter are produced. Before the reaction, you had pure sodium and water. After the reaction (which is very explosive by the way), you have sodium hydroxide and hydrogen gas.
Is ability to react with other substance a physical or chemical?
Chemical. If vinegar reacts with baking soda, a new substance is produced. If something new is produced, it is chemical. In chemical reactions, things change what they are. Water splitting into hydrogen gas and oxygen is chemical, because hydrogen gas and oxygen gas is different from water.
Is dicing potatoes a chemical change?
Slicing is pure mechanical, so physical but it is not a CHANGE but an ACTION or EVENT
Distinguish between physical and chemical change?
A chemical change is a change involving making and breaking chemical bonds to form new chemicals. For example when wood burns the carbon and hydrogen in the cellulose react with the oxygen in the air, forming carbon dioxide and water. A physical change is one that the chemical changes states and no new chemicals are formed, like melting ice or dissolving salt in water.
Is Ability to react with other substance a chemical property or physical?
Chemical. If vinegar reacts with baking soda, a new substance is produced. If something new is produced, it is chemical. In chemical reactions, things change what they are. Water splitting into hydrogen gas and oxygen is chemical, because hydrogen gas and oxygen gas is different from water.
