Help ASAP please! I don’t understand this at all.

Answers

well i think what you do first is that you would divide that number of amu by 6.02 x 10^23 and that will get you the number of moles of H2. once you have the number of moles you divide the number of moles by the molar mass of H2 and that should give you the grams. i’m trying to explain this as best as possible sorry if ur still confused.

How would you describe the change in the arrangement of particles as heat energy and temperature increase?

Answers

The change in the arrangement of particles as heat energy and temperature increase because of the increase in the kinetic energy of the particles.

How kinetic energy calculated?

Kinetic energy of any atom is calculated as:

K.E. = 1/2(mv²), where

v = velocity and m = mass

So, when we apply heat energy or increase the temperature of any system then the energy of the constitute particles is also increases which results in the increase of the average kinetic energy of the particle. Due to this kinetic energy particle will move with high velocity and disturbs the arrangement of the system.

Hence, due to increase in average kinetic energy, arrangement of the particles changes.

Explanation:

What examples does
- Making Materials
- Moving Materials
- Removing Waste

Answers

Answer:

You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled

Moving Materials include aluminum foil tape, shipping tape, box tape and duct tape. Moving labels take the guesswork out of the moving process.

What types of atoms form cations

Answers

Cations are formed when atoms lose electrons, resulting in a net positive charge.

Generally, cations are formed by atoms of metals. Metals tend to have relatively low ionization energies, allowing them to easily lose electrons and form positively charged cations. Examples of metals that commonly form cations include sodium (Na⁺), calcium (Ca²⁺), iron (Fe²⁺ or Fe³⁺), and aluminum (Al³⁺), among others. It is important to note that not all metals form cations, as some metals can exhibit variable oxidation states or form anions in certain compounds.

Hence, Cations are formed when atoms lose electrons.
