Answer:
The correct answer is B the tertiary halides reacts faster than primary halides.
Explanation:
During SN2 reaction the nucleophile attack the alkyl halide from the opposite side resulting in the formation of transition state in which a bond is not completely broken or a new bond is not completely formed.
After a certain period of time the nucleophile attach with the substrate by substituting the existing nuclophile.
An increase in the bulkiness in the alkyl halide the SN2 reaction rate of that alkyl halide decreases.This phenomenon is called steric hindrance.
So from that point of view the that statement tertiary halides reacts faster that secondary halide is not correct.
Answer:
d = 1.85 g/cm³
Explanation:
Given data:
Volume of sulfuric acid = 35.4 mL
Mass of sulfuric acid = 65.14 g
Density of sulfuric acid = ?
Solution:
1 ml = 1cm³
Formula:
d = m/v
d = 65.14 g / 35.2 cm³
d = 1.85 g/cm³
So if they fall, the padding will protect their neck or body part so they will not hit hard against the hard wooden or tile floor.
Answer:
The element is Na
Explanation:
Ionization energy is the energy needed to release the last electron from an atom in its ground state to the gaseous state. It is a periodic property that increases as we go through the periods of the periodic table, but decreases if we move in groups. Sodium has thr ionic radius (another periodic property) that is too large, making it easier to release the electron away, since it is too far from the nucleus.
Explanation:
mass of an object affect the density and object if the the volume is keep constant.
here we can explain by using the example.
if the mass of an object is 30kg. and volume is 2m3
then density pf given substance is become 15kg/m3
again,
if the mass of the is 40kg/m3 and volume is same
then density is become 20kg/m3 (formula=kg/m3)
here above density and below density is becime different by changing the mass of an object and affect the density and objecy although volume is kept constant or same
