Answer:

isotopes

Explanation:

The atoms of an element that have same number of protons but different number of neutrons are called as the isotopes of that element.

For example: _{1}^{1}(\textrm{H}\text{protium})\text{and}_{1}^{2}\textrm{H}(\text{deuterium}) are the isotopes of Hydrogen

Ions are the charged species of an atom that are formed by the gain or loose of electrons.

For example: \text{Na}^{+}

Neutrons are the sub-atomic particles found inside the nucleus of an atom. They carry no charge.

Compounds are the substances that are formed when two or more atoms combine in a definite proportion.

For example: NaCl

At a certain temperature, iron (II) oxide, FeO, can react with carbon monoxide, CO, to form elemental iron, Fe, and carbon dioxi
barxatty [35]

Answer:

The pressure of CO2 at the equilibriumis 0.185 atm

Explanation:

Step 1: Data given

The value of Kp at that temperature is 0.242

FeO was initially in a container with CO at a pressure of 0.95 atm

Step 2: The balanceequation

FeO(s) + CO(g) ⟷ Fe(s) + CO2(g)

Step 3:The initial pressure

pCO = 0.95 atm

pCO2 = 0 atm

Step 4: The pressure at the equilibrium

pCO = 0.95 - x atm

pCO2 = X atm

Step 5: Calculate Kp

Kp = pCO2 / pCO

0.242 = X / (0.95 - X)

X = 0.185

pCO = 0.95 - 0.185 =  0.765 atm

pCO2 = 0.185 atm

The pressure of CO2 at the equilibriumis 0.185 atm

Can some one plz help
blsea [12.9K]

The reaction uses B) 9.0 g Br₂.

 iron + bromine ⟶ product

2.0 g +     <em>x</em> g     ⟶   11.0 g

According to the <em>Law of Conservation of Mass</em>, the total mass of the reactants must equal the total mass of the products.

∴2.0 + <em>x</em> = 11.0

<em>x</em> = 11.0 – 2.0 = 9.0

The reaction uses 9.0 g Br₂.
