If the reactants of wood when burning weigh 10 kgs, how much will the products weigh?
aksik [14]

Answer:

the weight of products is is equal the weight of the wood plus the weight of oxygen that was used to burn that wood, so weigh of the product is greater than 10 kilograms.

Explanation:

Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.

In this example wood (mostly carbon) and oxygen are reactants and carbon dioxide (mostly) is product of reaction.

? Question
DedPeter [7]

Many of the men may believe that they are fair and unbiased against women.

Many of the women may already believe that they face biases.

<h3>What is confirmation bias ?</h3>

The propensity to seek for, understand, favor, and remember information that supports or confirms one's preexisting opinions or values is known as confirmation bias. People exhibit this bias when they choose facts that support their opinions while rejecting those that contradict them or when they interpret ambiguous facts as supporting their preexisting beliefs. Although confirmation bias cannot be completely avoided, it can be controlled, for instance, by critical thinking education and training.

Confirmation bias has been linked to poor decisions in the scientific, organizational, financial, and political spheres. These biases can preserve or reinforce views in the face of contradictory data and contribute to overconfidence in personal opinions.

Why is knowledge of mineral properties important? Which properties might be most useful in construction? In jewelry-making? Expl
Mashcka [7]

Answers with Explanations:

1. Why is knowledge of mineral properties important?

Knowledge of mineral properties is important because it <u>helps scientists know about the earth's history, particularly when it comes to "rock formations."</u> It is also essential in order to know which minerals are economically important.

2. Which properties might be useful in construction?

Minerals have many physical properties (<em>color, crystal form, hardness, luster, density, cleavage and fracture, etc.) </em>

When it comes to construction purpose, the mineral's malleability is very important. This is the reason why "iron" is one of the most important minerals being used in buildings. It's <em>malleability</em> allows it to be framed into "steel," which is then used to make even bigger infrastructures and skyscrapers.

3. In jewelry-making?

When it comes to "jewelry-making," the <em>hardness </em>and <em>luster</em> of the mineral may be used as a basis. For example, the diamond can be determined from the rest of the minerals because it is the hardest and it has a brilliant-kind of luster.
