Answer:
It is an Alkaline Earth Metal
Explanation:
Metallic bonding results from the delocalization of electrons from the parent metal atom so that positive ions are conceived to swim in a sea of electrons. This view of metallic bonding accounts for the malleability, and ductility of metals, as well as their properties of thermal and electrical conduction.
Hello!
The pressure of an 18 L container which holds 16,00 grams of oxygen gas (O₂) at 45 °C is
0,725 atmTo solve this problem we first need to set up the data in the appropriate units to input it in the
Ideal Gas Law.
a) 16 g of Oxygen gas to moles of oxygen gas:
b) 45 °C to K
Now, we clear the Ideal Gas Equation for P, and solve it:
Have a nice day!
Answer:
i think wait if its cold idk but hot it will burn u
Explanation:
Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
Answer:
S = 1.1 × 10⁻⁹ M
Explanation:
NaCl is a strong electrolyte that dissociates according to the following expression.
NaCl(aq) → Na⁺(aq) + Cl⁻(aq)
Given the concentration of NaCl is 0.15 M, the concentration of Cl⁻ will be 0.15 M.
We can find the molar solubility (S) of AgCl using an ICE chart.
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
I 0 0.15
C +S +S
E S 0.15+S
The solubility product (Ksp) is:
Ksp = 1.6 × 10⁻¹⁰ = [Ag⁺].[Cl⁻] = S (0.15 + S)
If we solve the quadratic equation, the positive result is S = 1.1 × 10⁻⁹ M
