Answer : The major and minor products of 2,4,4-trimethy-2-pentene will be a tertiary radical of Br which will be in major quantity whereas secondary radical of Br will be in minor quantity.

As the reaction follows anti-markonikov's rule the radical formed in tertiary state will be more stable and the secondary state will be much unstable as compared to tertiary state.

Note -  The structures are arranged in the attachment

For the reaction A+2B→C under a given set of conditions, the initial rate is 0.100 M/s.What is Δ[B]/Δt under the same conditions
Oliga [24]

Answer: The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.

Explanation:

A+2B\rightarrow C

Initial Rate of the reaction = 0.100 M/s

Rate of disappearance of B:

-\frac{1}{2}\frac{\Delta [B]}{\Delta t}=0.100 M/s

-\frac{\Delta [B]}{\Delta t}=2\times 0.100 M/s=0.200 M/s

The rate of disappearance ( -Δ[B]/Δt) under the same conditions is 0.200 M/s.

Write a net ionic equation for the reaction that occurs when nickel(ii carbonate and excess hydrobromic acid (aq are combined.
seropon [69]
First, we write the reaction equation:
NiCO₃ + 2HBr → NiBr₂ + H₂CO₃

Now, writing this in ionic form:
NiCO₃ + 2H⁺ + 2Br⁻ → NiBr₂ + 2H⁺ + CO₃⁻²

(NiCO₃ is insoluble so it does not dissociate in to ions very readily)

Overall equation:
NiCO₃ + 2Br⁻ → NiBr₂ + CO₃⁻²

Marie and Calvin dissolved 10 grams of KNO3 in 100 grams of water at 25oC. Next they added 5 grams more. Calvin told Marie that
PSYCHO15rus [73]
Hello!

Calvin told Marie that they could continue to add solute until the reached 40 grams because the solution was still unsaturated.

Unsaturated solutions are those in which the solvent (in this case water) can still dissolve more solute (in this case KNO₃) at the given pressure and temperature. This can be seen visually when adding more solute doesn't result in the presence of grains of solids that settle in the bottom of the flask. That happens because the rate of dissolving is higher than the rate of crystallization. 

Have a nice day!

sergeinik [125]
<span>The steps of solubility of water in N-butanol is as follows:1. N-butanol molecules are attracted to the surface of the water, 2. N-butanol molecules surround water molecules, 3. Butanol mixes with water and 4. Water molecules are carried into N-butanol.</span>

makkiz [27]
0.216g of aluminium compound X  react with an excess of water water to produce gas. this gas burn completely  in O2  to form H2O and 108cm^3of CO2 only . the volume of CO2 was measured at room temperature and pressure

0.108 / n  =  24 / 1 
n = 0.0045 mole ( CO2 >>0.0045 mole 
0.216 - 0.0045 = 0.2115
so Al =   0.2115 / 27  =>  0.0078 mole 
C = 0.0045 * 1000 => 4.5    and Al  = 0.0078 * 1000 = 7.8
