The reaction of 2-methylbutane with chlorine would yield how many monochloro derivatives (include stereoisomers)?
zimovet [89]
The reaction  of  2  methylbutane  with   chlorine  yield  5 monochloro  derivative.   Methylbutane  has  four  carbon  atoms  which  react with   chlorine.  The  carbon  with antibonding  will  be  chiral   and  it  will react  with  chlorine. there  will  be  four  difference  group  around  chiral  carbon  hence  it  will  have  stereoisomers.

The enzyme urease catalyzes this reaction. If urease is added to a solution that contains ammonia and other nitrogen-containing
Semmy [17]
The enzyme urease catalyze the hydrolysis of urea into ammonia and carbon dioxide. If urease is added to any compound which has no urea, it will not catalyze any reaction because if there is no urea, urease will not bind to any substance.

Hydrogen reacts with 0.771 g of carbon to form 0.90 g of a compound. What is the mass percent of hydrogen in the compound
morpeh [17]
Answer: 14.3%

Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound. 

In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen. 

Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.

Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.

So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%

Is precipitate in water an electrolyte solution
vagabundo [1.1K]
When no ions are produced, or the ion content is low, the solute is a non-electrolyte. Non-electrolytes do not conduct electricity or conduct it to a very small degree. In an aqueous solution a strong electrolyte is considered to be completely ionized, or dissociated, in water, meaning it is soluble
