Answer:
D
Explanation:
I took a study island on this
Answer:
Potassium has an atomic radius of 243pm
Calcium has an atomic radius of 194pm
Magnesium has an atomic radius of 145pm
Explanation:
Is it talking about the big bang theory?
Answer:Strong bases: OH-, CH3O-, CN-
Nucleophiles: OH-,CN-, NH2-
Leaving groups: Br-, Cl-, H2O,NH3
Explanation: Strong bases have a greater ability to abstract a proton in an elimination reaction. For instance, the OH- easily abstracts a proton to form water. Nucleophilicity is a kinetic property. It measures the rate at which a specie displaces a leaving group from an alkyl halide Good leaving groups are stable anions or neutral molecules. They are often conjugate bases of strong acids.
The hydroxide ion rarely, or almost never acts as a leaving group in SN2 reactions
The pressure of the gas <u>would increase.</u>
Explanation:
Using the ideal gas formulae we can evaluate this fact;
P₁V₁/T₁ = P₂V₂/T₂
We can assume that the volume is reduced by half (the T₁ and T₂ will cancel out because they remain constant);
P₁V₁ = P₂ * 0.5V₁
P₁V₁/0.5V₁ = P₂
P₁/0.5 = P₂
You can observe that the pressure will also increase – diving a number by a fraction or decimal number increases the resultant value. In this case, the pressure will increase by 2 fold
