Many of the lunar craters are due to volcanic eruptions true or false
elena-14-01-66 [18.8K]

Answer:

false

Explanation:

Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

Whats the structure and bonding of sodium chloride
anastassius [24]
Sodium Chloride is ordinary table salt

You have a small sodium atom with a positive charge Na+, and a larger chlorine atom with a negative charge, making it a Chloride ion, Cl-.

This ion formation has resulted from Na transferring one of its electrons to Cl. there opposite charges then attract them to each-other.

Because the electrons are transferred rather than shared, we know that the bond is Ionic, rather than covalent.

Most ionic compounds, if not all, are salts that form a crystal lattice structure, due to the opposite charges in the molecule.

Think of it like this

Na+—Cl-
Cl—-Na+
Na+—Cl-

That’s how the molecules attract and stick to each other. That would continue until you ran out of NaCl molecules.

Si se hace reaccionar CH3CH3 (etano) con cloro, en presencia de luz ultravioleta, los productos obtenidos en este paso son
Leni [432]

Answer:

La reacción de etano, CH₃CH₃ y cloro, Cl₂ en presencia de luz solar se conoce como reacción de halogenación.

Los radicales de cloro se forman cuando el cloro se expone a la luz solar a continuación;

Cl₂ → 2Cl *

Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;

C₂H₆ + Cl → C₂H₅ * + HCl

Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;

C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *

Un producto halogenado puede reaccionar además con un radical libre para producir como sigue;

C₂H₅Cl + Cl * → C₂H₅Cl₂

A student heats 3.55 grams of copper and 4.60 grams of iodine for 6.25 grams of a new compound. All of the iodine reacted, but t
Alex787 [66]
This item can be answered by using the concept of material balance. The amount of substance used for the reaction should be the same before and after the reaction occurred. 

Amount of reactants = 3.55 grams + 4.60 grams = 8.15 grams

We are also given that the amount of product accounted for is only 6.25 grams, this entails that not all copper was reacted. Subtracting this value from 8.15 g will give us an answer of 1.9 grams. 

Answer: 1.9 g of copper

What is atomic radius?​
vfiekz [6]
The chemical element's atomic radius is measured by the size of its atoms, usually the medium or typical distance between the central nucleus and the surrounding electron shells. As the limit is not a well defined physical entity, different definitions of non-equivalent atomic radius exist.

Hope this helps!
