Answer:

phosphorus - least similar to barium

beryllium - most similar to barium

Explanation:

The formula of the chloride formed between barium and chlorine is BaCl2.

Barium is a metallic element and has the valency of +2. Beryllium is also a group two metal with a valency of +2. Hence the compound formed between beryllium and chlorine is BeCl2

Phosphorus is a nonmetal and forms a completely different chloride from BaCl2. The chloride of phosphorus is PCl5 and PCl3. These are least similar to BaCl2

What is the volume of NH3 produced in the following reaction when 3.0L of N2 reacts with 4.0L of H2?
trapecia [35]

Hey there !

Given the reaction:

N2 + 3 H2 = 2 NH3

At constant pressure and temperature  ,volume is proporcional to moles:

Theoretical moles of  N2 and H2 =>  1:3

Theoretical volume of N2 and H2 => 1:3

Experimental volume of N2 and H2 => 3.0 L  :  4.0 L

0.75 : 1  = 2.25 : 3

Since N2 is in excess reactant   , H2 is the limiting reactant

Therefore:

volume  of NH3 is  2/3  * Volume of H2

= 2/3 * 4.0 = 2.66 L



Hope that helps!

An atom has a nucleus that has mass and volume. How does the mass of the nucleus compare to the mass of the atom? How does the v
makvit [3.9K]

Answer:

The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.

The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.

Gaseous hydrogen iodide is placed in a closed container at 425∘C, where it partially decomposes to hydrogen and iodine: 2HI(g)⇌H
murzikaleks [220]

Answer:

0.0184

Explanation:

Let's consider the following reaction at equilibrium.

2 HI(g) ⇌ H₂(g) + I₂(g)

The concentration equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their  stoichiometric coefficients divided by the product of the concentration of the reactants raised to their  stoichiometric coefficients.

Kc = [H₂] × [I₂] / [HI]²

Kc = (4.78 × 10⁻⁴) × (4.78 × 10⁻⁴) / (3.52 × 10⁻³)²

Kc = 0.0184
