Answer:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... As a result, the particles take up more volume.
The thermal energy is transferred in convection through the movements of fluids, such as air or water.
Thermal energy refers to the energy associated with the movement of particles in a system. As temperature increases, the particles in a substance gain kinetic energy and move faster, resulting in an increase in thermal energy.
When a fluid is heated, its molecules gain kinetic energy and begin to move faster, causing them to spread out and become less dense. This creates a region of warm, less dense fluid that rises upward due to buoyancy.
As the warm fluid rises, cooler, denser fluid moves in to take its place, creating a convection current. This process continues as long as there is a temperature difference between the warm and cool fluids. The movement of the fluids transfers thermal energy from the warmer areas to the cooler areas.
Therefore, In convection, thermal energy is transferred through the movement of fluids, such as air or water.

Is hydrogen the right answer y’all?
Answer:
The correct answer is hydrogen.
Explanation:
Stars in the main sequence will remain in the main sequence as long as their cores contain hydrogen atoms. This is because main sequence stars run on the hydrogen atoms within their core to prevent them from falling to the force of gravity. Once these hydrogen atoms run out, the star is no longer considered a main sequence star, gravity takes hold, and the star collapses.

Can someone help with question 6 ASAP
Answer:
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.
A series of six elements called the metalloids separate the metals from the nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. These elements look metallic; however, they do not conduct electricity as well as metals so they are semiconductors. They are semiconductors because their electrons are more tightly bound to their nuclei than are those of metallic conductors. Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form monatomic anions. This intermediate behavior is in part due to their intermediate electronegativity values. In this section, we will briefly discuss the chemical behavior of metalloids and deal with two of these elements—boron and silicon—in more detail.

Our digestive enzymes are able to break the alpha linkage in potatoes but not the ?? Linkage in paper
Answer:Beta
Explanation:
I watched the video and I got it wrong, the right answer was beta. I can’t explain why because I’ve already forgotten lol
Digestive tract have digestive enzymes which are not able to break beta linkages as humans do not have enzymes which breakdown beta linkages.
What is digestive tract?
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Put an aluminum atom, Al (aluminum) and an aluminum ion, Al^3+ in increasing (smallest to greatest) order. (Enter "Al" or "Al^3+" first, then enter a semicolon, then enter one space and then enter "Al" or "Al^3+" second.) 4 points
Answer:
Al^3+;Al
Explanation:
When a metal ion is formed, the corresponding ion is smaller than the atom from which it was formed.
Oftentimes, the formation of a metal ion leads to the loss of an entire shell. The reduces the ionic radius compared to the atomic radius. Hence the metal ion is always much smaller than the metal atom.

its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:
so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g
