The atomic number of an element is based on the number of protons in the atomic nuclei of its atoms.

Answer:

hope it helps...

Explanation:

Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

A compound that conducts an electric current in aqueous solution or in the molten state.

makvit [3.9K]

Answer:

A compound that conducts an electric current in aqueous solution or in the molten state is a ionic compound.

E.g. NaCl (table salt)

Explanation:

Some examples of ionic compounds are NaCl, KF, KI, MgSO₄.

Ionic compounds are formed by positivie ions (named cations) and negative ions (named anions). The strong electrostatic atraction between cations and anions permits the formation of crystals, which are stuctures characterized by a regular pattern. In solid state the ions are in fixed positions.

In order to conduct electricity, the charged particles (cations and anions in the case of the ionic compounds) need to move freely.

Hence, since in solid state, ionic compounds do not conduct electric current. But, in molten (liquid) state or in aqueous solution, ionic compounds conduct electric current because, then, the ions move freely.

when carbon is burned in the air, it reacts with oxygen to form carbon dioxide. when 22.8 g of carbon were burned in the presenc

OverLord2011 [107]

Answer:

So there is83.6g CO2 produced

Explanation:

Burning carbon with air has the following equation

C + O2 → CO2

For 1 mol Carbon, we have 1 mol O2 and 1 mol CO2

Step 2: Calculating moles

mole C = 22.8g / 12g/mole

Mole C = 1.9 mole

1.9 mole C will completely react

Since for each mole C there is 1 mole O2 and 1 mole CO2

This means there will also react 1.9 mole of 02, to be formed 1.9 mole of CO2

mole CO2 = mass CO2 / Molar mass CO2

mass CO2 = 1.9 mole CO2 * 44g/mole =83.6g CO2

In this reaction 18.2 g of O2 remained unreacted

we can control this: 79g - 18.2 g = 60.8g

1.9 mole * 32g/mol = 60.8g

So there is83.6g CO2 produced
