Answer:
See explanation and image attached
Explanation:
The reaction of HBr with 1-butene is an addition reaction. The HBr adds across the double bond to yield a saturated halogenoalkane.
In the absence of peroxides, the reaction proceeds in accordance with Markovnikov rule which states that;''the negative part of the addendum, is attached to the carbon atom with the least number of hydrogen atoms attached.'' This occurs in the first reaction shown in the image.
In the presence of peroxides, the reaction proceeds in an anti-Markovnikov manner to yield the product shown in the second reaction.
Ok so O3 has a greater electronegativity and is taken into account first, -2*3=-6, so As has to equal 6/2=3, so As has a +3 oxidation number here
I believe it is asexually as a mushroom can produce spores if its the only mushroom for miles. Hope this helps! <span />
Answer:
letter a."Grounding"
Explanation:
Why?
Because when the voltage at the end of the rod is sufficiently high it will bleed-off some of the induced lightning charge on the ground, streamers will be reduced or eliminated and the likelihood of a lightning strike is reduced. A corona develops at the tip of the rod, which sometimes can be seen
Answer:
6.624× 10²³ molecules
Explanation:
Given data:
Mass of KOH = 60 g
Number of molecules = ?
Solution:
First of all we will calculate the number of moles.
Number of moles = mass/molar mass
Number of moles = 60 g/ 56.1 g/mol
Number of moles = 1.1 mol
Now number of molecules are determine by using Avogadro number.
1 mole = 6.022 × 10²³ molecules
1.1 mol × 6.022 × 10²³ molecules / 1mol
6.624× 10²³ molecules
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
