Mole - one of the most important concepts in chemistry - is a kind of link to go from the microworld of atoms and molecules in a normal macrocosm grams and kilograms.
In chemistry often have to consider large numbers of atoms and molecules. For fast and efficient calculation made using the weighing method. But it is necessary to know the weight of individual atoms and molecules. In order to identify the molecular weight must be added the weight of all atoms in the compound.

Which is the correct name of a compound that is formed by Si and O?

svp [43]

Naming conventions for 2 non-metals like Si and O are based on their valence electrons, Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O, To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"

What occurs as energy is transferred through the radiative zone of the sun? check all that apply. gamma rays are produced. photo

AlladinOne [14]

Answers:

1) Photons are absorbed by hot gas atoms.

2) Energy is transferred through large-scale movement of material.

3) Energy is released into the photosphere.

The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.

The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.

Radiative zone is around the inner core and in this area energy is transported by radiation.

The convection zone is the outer-most layer of the interior and in this area energy is transported by convection.
