What was the catalyst for the switch from food gathering to food preductions what are the essential differences between the two?
The catalyst for the switch from food gathering to food production was the development of agriculture, driven by climate changes at the end of the last Ice Age that favored the domestication of plants and animals. Food gathering, or foraging, involves collecting wild plants and hunting animals, while food production entails cultivating crops and raising livestock for a stable food supply. This transition allowed for settled communities, population growth, and the development of complex societies, differentiating it from the nomadic lifestyle of foragers. Ultimately, food production enabled greater control over food resources and economic surpluses.

How do you remove from a catalyst?
To remove a catalyst from a reaction mixture, you can use filtration, centrifugation, or extraction methods, depending on the state of the catalyst (solid or liquid) and the nature of the mixture. For solid catalysts, filtration is often effective, while centrifugation can separate solid catalysts from liquids based on density differences. If the catalyst is soluble in the reaction medium, extraction with a suitable solvent may be necessary. After removal, the catalyst can often be reused or disposed of according to appropriate environmental guidelines.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What is the catalyst for sodium persulfate?
The catalyst for sodium persulfate is typically a transition metal ion such as iron or copper. These metal ions help initiate the decomposition of sodium persulfate into sulfate radicals, which are essential for various oxidation reactions in chemistry.
How is a catalyst like platinum different from an enzyme?
A catalyst like platinum is a non-biological substance that speeds up chemical reactions by providing an alternative pathway with lower activation energy. Enzymes, on the other hand, are biological catalysts that are specific to certain reactions and are essential for biological processes. Enzymes are made up of proteins and can be regulated by the cells that produce them, while catalysts like platinum are typically inorganic and do not have this level of specificity or regulation.
Is a catalyst safe?
A catalyst is generally considered safe in the context of chemical reactions, as it typically facilitates a reaction without being consumed or altering its own chemical structure. However, the safety of a catalyst depends on its specific type and the environment in which it is used. Some catalysts can be toxic or hazardous, so it's essential to handle them according to safety guidelines and regulations. Always consult material safety data sheets (MSDS) for specific information on the safety of a particular catalyst.

Give two essential features of a catalyst?
- it speeds up the reaction by offering an alternative root. - it remains the same at the end of the reaction.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What macromineral is a catalyst in the release of energy from adenosine triphosphate?
Magnesium is the macromineral that acts as a catalyst in the release of energy from adenosine triphosphate (ATP). Magnesium ions are essential for the activity of enzymes that are involved in the hydrolysis of ATP to produce energy for cellular processes.

Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
Why are enzymes known as bio-catalyst?
Enzymes moderate chemical changes within an organism, and are usually essential to making metabolic functions occur at the proper rates.
