Answer these questions:
1. How is a mixture different from a compound?
2. How are the atoms in a compound held together?
Classify the following as mixtures, elements, or compounds:
3. H20
4. H4
5. Fe + S
Answer:
1.A compound is when two substances are put together and there is a reaction creating a new substance Ex. H20. A mixture is when two substances are put together, there is no reaction and they can be separated easier than compounds. Ex. salad dressing.
2.Atomic bonds
3.Compound

Do you think we might have problems with not enough water to supply our needs (water scarcity) in the
ture? Why or why not? If you answered yes, what might the causes be?
Answer:
Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution. This was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] Two-thirds of the global population (4 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world's largest cities experience water scarcity.[5]

what is acceleration
Answer: acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Classify each substance as either a conductor or insulator.
A sample of mercury:
✔ conductor
A piece of glass:
✔ insulator
A rubber hose:
✔ insulator
A negatively ionized lithium paste:
✔ conductor
The correct classification of each substance is as follows:
A sample of mercury: conductorA piece of glass: insulatorA rubber hose: insulatorA negatively ionized lithium paste: conductorWhat are conductors and insulators?A conductor is a substance that can transmit electricity, heat, light or sound while an insulator is a substance that does not transmit heat, sound or electricity.
Conductors are usually metals while insulators are usually non-metals. Examples of conductors include;

Explanation:
Dietary fiber contains an indigestible material known as cellulite. This is false statement.
What is Dietary fiber?Plant substances that are not broken down by human digestive enzymes are referred to as dietary fiber.
Only lignin and a few polysaccharides were recognized as meeting this criterion in the late 20th century, but resistant starch and oligosaccharides were listed as dietary fiber components in the early 21st century.
The phrase "all polysaccharides and lignin, which are not digested by the endogenous secretion of the human digestive tract" is commonly used to define dietary fiber.
At the moment, the majority of animal nutritionists either use a physiological definition, which states that "dietary components resistant to breakdown by mammalian enzymes," or a chemical definition, which states that "the sum of non-starch polysaccharides (NSP) and lignin."

What happens to the arrangement of atoms in matter as it is heated?
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance.
Explanation:
A(n) ________________________ is a substance that slows down a chemical reaction.
endergonic
exergonic
exothermic
inhibitor
endothermic
Answer:
inhibitor
Explanation:
Inhibitors slow down chemical reactions. Inhibitors slow down or stop the activity of an enzyme.

difference between sold and liquid
Explanation:
Solids have closely packed particles and vibrate about a fixed position, they also have a fixed volume.
liquid have close particles but which are able to move with a bit of kinetic energy, for this reason they have no fixed volume but take the volume of the container or vessel

Certain specialised devices can be more than 100% efficient. True or false?
Certain specialized devices can be more than 100% efficient is referred to as a false statement.
What is Efficiency?This is referred to as a way of measuring how much energy can be conserved in a process. On the other hand, energy is the ability to do work and can be lost through various means such as heat.
It is not possible to have an efficiency of 100% because it means that there will be more energy being transferred than what is being supplied which would break the law of conservation of energy and is therefore the reason why false was chosen as the correct choice.
