Is lighting fireworks chemical or physical?
Lighting fireworks involves both chemical and physical changes. The combustion of the chemical compounds in the fireworks produces gases and heat, which is a chemical change. Simultaneously, the explosive reactions cause physical changes, such as the release of light and sound, and the transformation of solid materials into gases and particles. Thus, the process encompasses both types of changes.
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
What type of chemical agent when released can cause casualties for several days or weeks?
A biological agent
Is a toast a chemical or physical change?
Chemical
What chemical compounds cause fireworks to explode?
The explosion in fireworks is caused by the rapid combustion of gunpowder, a mixture of potassium nitrate, charcoal, and sulfur. When ignited, the gunpowder releases a large amount of gas which rapidly expands and creates the characteristic explosions of fireworks.
Which agent of metamorphism can cause the overall composition of rock to change?
Hydrothermal fluids are a common agent of metamorphism that can cause the overall composition of a rock to change. These fluids can introduce new minerals into the rock through chemical reactions, altering its composition and structure.
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
What type of chemical agent when released can cause casualties for several days or weeks?
A biological agent
Can a chemical cause a chemical change?
A chemical change can be caused by a reaction. It an element or compound reacts with another, it is known as a chemical change.
What type of chemical agent can cause casualties 24 hours after contact?
A persistent agent. Any of the classes of chemical agents - nerve, blood, blister and so on - can be made into a persistent agent.
Is a toast a chemical or physical change?

An agent that can cause a change in DNA is called a?
mutagen
What is a dispersal agent?
A dispersion agent is a chemical substance that is added to a liquid to prevent it from hardening. The agent will cause distribution of ingredients in the entire product.
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
Which type of chemical agent when released can cause casualties for more than?
Persistent
Does evaporation cause a physical change or a chemical change?
It is physical change
