Answer:
THE NEW VOLUME OF THE GAS IS 406 mL WHEN THE TEMPERATURE CHANGES FROM 765 K TO 315 K.
Explanation:
When the temperature changes from 765 K to 315K, the volume has changed from 986 mL to?
V1 = 986 mL = 0.986 L
T1 = 765 K
T2 = 315 K
V2 = unknown
Using Charles' equation of gas laws;
V1 / T1 = V2 / T2
Making V2 the subject of the formula:
V2 = V1 T2 / T1
V2 = 0.986 * 315 / 765
V2 = 0.406 L
V2 = 406 mL
So therefore, the volume of a gas changes from 986 mL to 406 mL as a result of a change in temperature from 765 K to 315 K.
Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed.</span>
Sodium belongs to Group 1A. It means that sodium has 1 valence electron. It needs to complete its octet electron or have the same configuration of a noble gas to become a stable ion. It would likely to release 1 electron to complete its octet than accept 7 more. Therefore, its ion form would be Na+.
<h3>What's Electronic configuration?</h3>
- The arrangement of an snippet's or patch's( or other physical structure's) electrons in their infinitesimal or molecular orbitals is known as the electron configuration in infinitesimal drugs and amount chemistry.
- For case, the neon grain's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, singly, are present in each of the 1s, 2s, and 2psubshells.
- According to electronic configurations, each electron moves collectively within an orbital while being girdled by an average field produced by all other orbitals.
- Slater determinants or configuration state functions are used to mathematically describe configurations.
<h3>What part does electronic configuration play?</h3>
- The chemical responses that an snippet can engage in as well as the types of motes that tittles can combine into to produce more complex composites depend on the electrical configuration of the snippet.

Answer:
Electric and heat
Explanation:
Forms of solar energy include electricity and heat
1) Body tube (Head): The body tube connects the eyepiece to the objective lenses. Arm: The arm connects the body tube to the base of the microscope. Coarse adjustment: Brings the specimen into general focus. Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
2)Microscopes are made up of lenses for magnification, each with their own magnification powers. Depending on the type of lens, it will magnify the specimen according to its focal strength.
3)In simple magnification, light from an object passes through a biconvex lens and is bent (refracted) towards your eye. ... The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x. (Microscopes usually come with a set of objective lenses that can be interchanged to vary the magnification.)
