Be 2+ is the charged ion of Be
-same amount of protons and neutrons, but has 2 less electrons, giving it full valence shell and + 2 charge
Answer:
The answer is NH3 and CH3OH
Explanation:
The basic rule of a reaction is "like dissolves like" and for a homogenous mixture to form, there must be some common properties related to bonding.
1. KI and Hg
Normally mercury tends to form amalgam which is not a homogeneous solution.
2. LICL and C6H14
One is non polar and other is polar which makes the homogeneous reaction not possible.
3. C3H8 and C2H5OH
Both are miscible but will not develop homogeneous solution as propane is gas at normal temperature.
4. F2 and PF3
Flourine is highly electronegative and will repel fellow flourine making it not possible for homogeneous solution
5. NH3 and CH3OH
Both have same type of bonding and can react homogeneously.
Answer: The answer is D.gram
Explanation:
Answer:
450.0 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
<em></em>
V₁ = 760.0 L, P₁ = 450.0 mm Hg,
V₂ = ??? L, P₂ = 760.0 mm Hg (standard pressure = 1.0 atm = 760 mm Hg).
∴ V₂ = (P₁V₁)/(P₂) = (760.0 L)(450.0 mm Hg)/(760.0 mm Hg) = 450.0 L.
