Answer:

2Fe(s) + 3Cl2(g) → 2FeCl3(s)

Explanation:

Step 1: Data given

iron = Fe = solid = Fe(s)

chlorine = Cl2 = gas = Cl2(g)

iron(III) chloride = FeCl3 = solid = FeCl3(s)

Step 2: The unbalanced equation

Fe(s) + Cl2(g) → FeCl3(s)

Step 3: Balancing the equation

Fe(s) + Cl2(g) → FeCl3(s)

On the left we have 2x Cl (in Cl2) and on the right side we have 3x Cl (in FeCl3). To balance the amount of Cl we have to multiply Cl2 (on the left) by 3 and FeCl3 by 2.

Fe(s) + 3Cl2(g) → 2FeCl3(s)

On the left side we have 1x Fe and on the right side we have 2x Fe (in 2FeCl3). To balance the amount of Fe, we have to multiply Fe on the left side by 2. Now the equation is balanced.

2Fe(s) + 3Cl2(g) → 2FeCl3(s)

What are the spectator ions in the reaction between mg(oh)2 (aq) and hcl (aq)?
vivado [14]

The spectator ions in the reaction between aqueous Mg(OH)_2 and aqueous HCl would be   Mg^{2+ and Cl^- ions.

<h3>What are spectator ions?</h3>

Spectator ions are anions or cations that exist both as reactants and as products in a reaction. Their forms remain unchanged both in the reactants and in the products.

Aqueous Mg(OH)_2 and aqueous HCl  react according to the following equation:

Mg (OH)_2 (aq) + 2HCl (aq) --- > MgCl_2 (aq) +2 H_2O (l)

Before the reaction, Mg^{2+ and Cl^- existed in the reactants as Mg(OH)_2 and HCl respectively. After the reaction,  Mg^{2+ and Cl^- exist as MgCl_2 in the product.

Thus, the spectator ions in this case are  Mg^{2+ and Cl^- ions because their forms did not change after the reaction.

The carbon-oxygen bond in CO has a higher bond dissociation enthalpy than a carbon-oxygen bond in CO2. Which is the best explana
kkurt [141]

Answer:

CO HAS A TRIPLE BOND WHILE C-O BOND IN CO2 IS A DOUBLE BOND

CO HAS A LONE PAIR ON CARBON WHILE CO2 DOES NOT

Explanation:

Bond dissociation bond enthalpy or energy is the energy needed to break 1 mole of a divalent molecule into separate atoms mostly in the gaseous state.

The carbon and oxygen in carbon monoxide form a triple bond as carbon monoxide has 10 electrons in their outermost shell which results into six shared electrons in 3 bonding orbitals as against the double bond formed by other carbon compounds. Four electrons come from oxygen and the remaining two from carbon and due to this, two electrons from oxygen will occupy one orbital and this forms a dative bond. Also because of the triple bond, carbon monoxide is often regarded as a more stable compound than carbon dioxide with a double bond. This gives it its higher bond dissociation enthalpy value and more energy is needed to break it into its separate atoms. This is in conjunction with a larger bond length similar to the bong length in a triple bond. This makes it more stronger than the bond dissociation enthalpy of carbon dioxide having a double bond.

State the bond angle and the molecular shape of NH3 and H2O.​
FinnZ [79.3K]

Answer:

H2O forms a bent structure due to the presence of 2 lone pairs over O Atom. This makes the bond angle 104.5° NH3 forms a pyramidal structure due to presence of 1 lone pair. This makes the bond angle 107°

What metals will react with hydrochloride acid to yield hydrogen gas
Alenkasestr [34]
I don’t know if this helps or not I’m still Not used to answering questions on Brainly These metals — beryllium, magnesium, calcium and strontium — react with hydrochloric acid to form a chloride and free hydrogen. Metallic magnesium when combined with hydrochloric acid, will naturally result in magnesium chloride -- used as a dietary supplement -- with the hydrogen being released as a gas.
