Beryllium has two inner shell electrons
olchik [2.2K]3 years ago
5 0
And two 2s electrons in the Be atom. Its electron configuration is thus 1s22s2or[He]2s2 The symbol [He] denotes the inner shell of two 1s electrons which have the same configuration as the noble gas He. The beryllium atom is noticeably smaller than the lithium atom

Reduce the following equation to a net ionic equation: 2Na+ + SO4^2- + Ba^2+ + 2Cl^- ---> 2Na^+ + 2Cl^- + BaSOv4
Eduardwww [97]

net ionic equation

B) SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

Explanation:

We have the following chemical equation:

2 Na⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 Cl⁻ (aq) → 2 Na⁺ (aq) +  2 Cl⁻ (aq) + BaSO₄ (s)

To get the net ionic equation we remove the spectator ions and we get:

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

were:

(aq) - aqueous

(s) - solid

Calculate the root mean square (rms) average speed of the atoms in a sample of xenon gas at 0.15 atm and -55c
GrogVix [38]
Answer:
Vrms is 149.7266 m/sec

Explanation:
The root means square velocity of a gas can be calculated as follows:
Vrms = \sqrt{ \frac{3RT}{M}}
where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg

Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec

Hope this helps :)
