Which two solutions would be the BEST choice for their experiment?
Margaret [11]

Solutions 1 and 3 because they are strong acids and a strong base. <u>Option A.</u>

<u />

Strong acids and strong bases are completely ionized in an aqueous solution. Weak acids and weak bases also ionize, but only partially and the reaction is reversible. So you know if an acid or base is strong or weak. A simple way to determine strength is to add the acid or base to water. A higher reactivity means a stronger acid or base.

One of the simplest tests to determine whether a solution is an acid or base is the litmus paper test. To do this, dip a special strip of paper so-called litmus paper into the solution and observe the color of the paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Sodium hydroxide is the strongest base because it completely dissociates to form sodium and hydroxide ions. These hydroxide ions are further treated with hydrogen ions by an acid to completely ionize the hydrogen ions.

Borane (BH3) adds to alkenes to form an alkylborane. In the first box draw the mechanism arrows, and in the second box draw the
OLEGan [10]

Answer:

The reaction when the Borane (BH3) is add to an alkene and form an alkylborane is shown below.

Explanation:

The boron of the borane does not have extra electron pairs, in this way the double bond of the alkene attacks the boron and the hydrogen belonging to the borane adheres to the carbon that is more substituted, thus forming an alkyl borane.

An environmental study of a certain metropolitan region indicates that given population x (in thousands), the average daily leve
Vedmedyk [2.9K]

Answer:

In 4 years the carbon monoxide level reach 7.8 parts per million.

Explanation:

The average daily level of carbon monoxide in the air is given by :

c(x) = 0.5x + 2 parts per million..[1]

The population of the region after t years is modeled by the formula :

x(t) = 10 + 0.1t^2...[2]

If level of carbon monoxide level reach 7.8 parts per million in t years.

Using [1] to calculate value of x.

c(x)= 7.8 parts per million

c(x) = 0.5x + 2  parts per million

7.8 parts per million = (0.5x + 2 ) parts per million

Solving for x , we get ;

x = 11.6

Using [2] to calculate value of t.:

x(t) = 11.6

11.6 = 10 + 0.1t^2

Solving for 't' we get ;

t = 4 years

In 4 years the carbon monoxide level reach 7.8 parts per million.
