What happens to electronegativity as you go down the same group
on the Periodic Table?
Answer:
decreases
Explanation:
As you go down the same group on the periodic table, the electronegativity of an atom will decrease.
A sample of an unknown gas occupies 5.51 L at 1.31 atm. What pressure would thisgas exert in a 0.520 L container if the temperature is held constant?
Answer:
P₂ = 13.9 atm (3 sig. figs.)
Explanation:
The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...
P ∝ 1/V => P = k/V => k = P·V
For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂
Given:
P₁ = 1.31 atm.
V₁ = 5.51 L
P₂ = ?
V₂ = 0.520 L
V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)

when you take 10 grams of salt, and dissolve it in 25 grams of hot water what is the solubility
Answer:
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

the chemical bond between elements of the two terminals of the periodic table is
Answer:
Covalent bonds are much more common in organic chemistry than ionic bonds. A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons. The electrons located between the two nuclei are bonding electrons.

IT'S FALSE ISN'T IT? YEHWhat is the molarity of 48.6 g of magnesium (Mg) ions in 4 L H2O? Show cancelation of units to get credit. PLEASE HELP!!!
Answer:
0.50M (1 sig. fig.)
Explanation:
The problem objective is 'Molarity (M)', so set up given data to reduce to moles per liter. That is ...
Molarity = moles Mg/Liters of solution = (48.6g/24.31g·mole⁻¹)/(4Liters) = 0.499794323M (calc. ans.) ≅ 0.5M (1 sig. fig.)

calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?
Answer: 0.25 moles NH3
1.51x10^23 molecules NH3
Explanation:
5.6dm3 (cubic decimeters)
1 dm^3 = 1 liter
We have 5.6L of ammonia (NH3 gas) at STP. All gases at STP occupy 22.4 liters/mole. Use this information as a conversion factor:
(22.4 L NH3)/(mole NH3)
Therefore:
(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3
Use Avogadro's number to convert moles to particles/molecules
(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3
What is wrong with writing the electron configuration of a ground state atom as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 ?
Answer:
Writing of the subshells
Explanation:
Given configuration:-
[tex]\\ \sf\longmapsto 1s^22s^22p^63s^23p^63d^{10}4s^2[/tex]
Actual configuration:-
[tex]\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^23d^{10}[/tex]
This is because 4s orbital is less in energy than that of 3d
