What else can I help you with?
What is used to contain sulfuric acid?
Sulfuric acid is commonly stored in containers made of materials like glass, plastic, or certain metals such as stainless steel or aluminum that are resistant to its corrosive properties. These containers are designed to prevent leaks or reactions with the acid.
Electrolytes determine most of the chemical and physical reactions of the body?
True
What does the arrangement and number of the valence electrons determine?
All chemical reactions.
An element behaves the way it does because of the number of arrangements of?
its electrons in energy levels and shells, which ultimately determine its chemical and physical properties. The number of electrons and their distribution around the nucleus influences an element's reactivity, bonding tendencies, and overall behavior in chemical reactions.
What determine the atom chemical properties?
Chemical reactions depends on the valence electrons.
Why is it important to study chemical ractions in closed containers?
Studying chemical reactions in closed containers allows researchers to control the experimental conditions more accurately, preventing the loss of reactants or interference from external factors. It also helps in understanding the stoichiometry of the reaction and determining the reaction rate. Additionally, studying reactions in closed containers can provide insights into the energetics and equilibrium of the process.
Do you return all unused chemicals to their original containers?
No, it is not safe to return unused chemicals to their original containers as this may cause contamination or lead to chemical reactions. Instead, they should be properly disposed of according to safety guidelines and regulations.
What is the significance of the arrangement of electrons in atom shells?
The arrangement of electrons in atom shells determines the chemical properties of an element. It affects how atoms bond with each other to form molecules and compounds. The number and distribution of electrons in the shells also determine the element's reactivity and ability to participate in chemical reactions.
What atomic particles are most important in determining chemical reactions and why?
electrons, because they determine the load of the particle
Why must a gas be kept in a closed containers?
A gas must be kept in closed containers to prevent it from escaping into the atmosphere, which can lead to loss of the substance and potentially create hazardous conditions. Additionally, containing the gas allows for the maintenance of pressure and temperature, which are crucial for many chemical reactions and processes. Closed containers also help to minimize contamination and ensure safety by preventing the interaction of the gas with other substances.
What is term catalyst is introduced by?
The term "catalyst" was introduced by the Swedish chemist Jöns Jacob Berzelius in the early 19th century. He used this term to describe substances that accelerate chemical reactions without themselves being consumed in the reaction.
Which of the following combustion reactions is balanced correctly?
The correct answer is: C5H12 + 8O2 5CO2 + 6H2O.
