Answer:

They are both words, so it depends on when you use it.

Explanation:

con·duc·tion

/kənˈdəkSH(ə)n/

Learn to pronounce

noun

the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

con·vec·tion

/kənˈvekSH(ə)n/

Learn to pronounce

noun

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

When 12 grams of carbon react with 32 grams of oxygen, the compound carbon dioxide (a greenhouse gas) is formed. What is true ab

musickatia [10]

Answer:

Option C = 6 of carbon react with 16 g of oxygen.

Explanation:

In given question it is stated that 12 g of carbon react with 32 g of oxygen to produce carbon dioxide. The other combination option c is also true because in this, the quantity of both reactant is just half from the given quantity. Which means that if 100 % product is obtained from the 12 g of carbon and 32 g of oxygen then by taking the half amount of reactant the product will be half i.e 50% .

This combination is true because the ratio of both reactant are justified.

Carbon 12g + Oxygen 32g → carbon dioxide

C : O 1 : 2.6

Option C:

Carbon ( 12/2 =6g ) + Oxygen (32/2 = 16g) → Carbon dioxide

C : O 1 : 2.6

Describe the pattern of the lewis dot structure of the first 18 elements

posledela

Explanation: Lewis dot structures are the structures which represent the valence electrons of an atom. The dots in the structure are considered as the valence electrons.

First 18 elements of the periodic table are Hydrogen(H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon(Ne), Sodium (Na), Magnesium (Mg), Aluminium (Al), Silicon (Si), Phosphorous (P), Sulfur (S), Chlorine (Cl) and Argon(Ar).

The valence electrons are the electrons which are present in the outermost shell of an atom. The electronic configuration of the elements are:

Hydrogen (H) = $1s^1$ ; Valence electrons = 1
