Astatine is At in the periodic table, hope I helped :))
Answer: The major product of the reaction between Hydrobromic Acid and 2-bromo-1-butene in the presence of ether and acid is 2,2-dibromobutane.
Explanation:
The mechanism of the reaction is supported by the Markovnikov's rule which explains that in the addition reaction of alkenes by hydrogen-halogen compounds, the incoming halogen substituent goes to the more substituted Carbon. It can also be stated that incoming hydrogen atom goes to the Carbon with more Hydrogen atoms.
The only case when the reverse of Markovnikov's rule takes place is when Hydrogen peroxide is present and the addition reagent is HBr.
This case is not like that and it simply follows the Markovnikov's rule.
I'll add an attachment of the reaction to this now.
Answer:
313.5cm²
Explanation:
Given parameters:
Weight of model = 105pounds
Pressure applied on the scale by model = 2.16pounds per square inch
Unknown:
Area of her feet in cm² = ?
Solution:
Pressure is the force per unit area;
Pressure =
Input the parameters and solve;
2.16 = ![\frac{105}{Area}](https://tex.z-dn.net/?f=%5Cfrac%7B105%7D%7BArea%7D)
105 = 2.16 x Area
Area =
= 48.6in²
We need now to convert the in² to cm²
1in² = 6.45cm²
48.6in² = 48.6 x 6.45 = 313.5cm²
1 roll of nickels has 40 nickles.
40 * 3 = 120
120 nickels in 3 rolls of nickels.
To separate hydrogen and oxygen from water you would have to perform B. decomposition (specifically, electrolytic decomposition!)
Hope this helps :)
