Answer:

The number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

A compound is a substance that is a mixture of more than one elements.

Compounds are made of two or more elements. These elements are represented by their symbols. These symbols can be identified and the number of elements represented by these symbols are counted.

For example, in the compound H_2OH

O :

H represents Hydrogen

O represents Oxygen

The elements in Water ( H_2OH

O ) are Hydrogen and Oxygen

Therefore, the number of elements in H_2OH

O is 2

Also in, NaClNaCl

The elements are Sodium(Na) and Chlorine(Cl)

There are two elements in NaCl

Hence, the number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

A sample of ideal gas is in a sealed container. The pressure of the gas is 485 torr , and the temperature is 40 ∘C . If the temp

Fantom [35]

Answer:

537.68 torr.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n and V are constant, and have different values of P and T:

(P₁T₂) = (P₂T₁).

P₁ = 485 torr, T₁ = 40°C + 273 = 313 K,

P₂ = ??? torr, T₂ = 74°C + 273 = 347 K.

∴ P₂ = (P₁T₂)/(P₁) = (485 torr)(347 K)/(313 K) = 537.68 torr.

Genrish500 [490]

Salt compounds are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice. It is held together by electrostatic forces known as ionic bonding. Ionic bonding refers to the chemical bond between two oppositely charged ions - a cation and an anion. This type of bond forms when there is a large electronegativity difference between two atoms.
