Answer: milkshake

Explanation:

A science laboratory is a place where potentially reactive and harmfull chemicals can be found. Chemicals like hydrochloric acid, ethanol, and useful neutral solvent like water can also be found in the science laboratory.

Milkshake is a liquid mixture that can be found in the kitchen or restaurant.

What is a chemical change?

PIT_PIT [208]

A chemical change is a change that results in new chemicals (the reactants underwent a chemical change which resulted in new products).
an example of a chemical change is the burning of paper. An example of something that is not a chemical change is the melting of ice.

The ____ are new substances that are created following a chemical reactions

amm1812

Answer : The Product are the new substances that are created following a chemical reactions.

Explanation :

Chemical reaction : A chemical reaction occur when two or more reactants react to form a new substance.

Reactant : A substance that is involved in a chemical reaction.

Product : A new substance that is formed in a chemical reaction.

For example : $A+B\rightarrow AB$

In this, A and B are the reactants and AB is the product.

Therefore, the answer is Product.

flammability is a material's ability to burn in the presence of a. hydrogen b. nitrogen c. oxygen d. carbon dioxide

Olegator [25]

Oxygen.

<h3>Further explanation</h3>

Chemical properties can be observed only when the substance changes into one or more different substances through chemical reactions or transformations. One of the chemical properties is flammability.

Flammability is a material's ability to burn in the presence of oxygen.

Remember, oxygen doesn't burn. Precisely flammable substances obtain substances that burn. Oxygen remains an oxidizing agent, which means it supports the combustion process. Oxygen causes other objects to catch fire at low temperatures and burns hotter and faster. But oxygen itself does not burn. Consequently, if you at present deliver fuel and fire, adding oxygen will provide the fire.

Carbon dioxide is the result of combustion. An example can be seen in firewood in a fireplace. One of the chemical properties of carbon-based wood is having the ability to burn. Chemically the wood turns into carbon dioxide when it burns and leaves a residue of ash. Furthermore, this ash residue cannot be turned back into the wood. Chemical changes result in new substances.

Consider an example of a combustion reaction to methane gas:

$\boxed{ \ CH_4_{(g)} + 2O_2_{(g)} \rightarrow CO_2_{(g)} + 2H_2O_{(g)} \ }$

Our balanced equation for methane combustion implies that every one CH₄ molecule reacts with two O₂ molecules. The product of combustion is one carbon dioxide molecule and two steam or water vapor molecules.
