Acetic acid is a weak acid and sodium hydroxide is strong base. Salts of the two will hydrolyse to give basic solution. So, at neutral point, pH of the solution will be greater than 8.

2. A truck is traveling east through mud that is slowing down its speed. With west defined as negative, which of the following i

Lynna [10]

Hi! The answer is C

As west is defined as negative, the trucks velocity is positive, since its travelling east. But its speed (absolute value of velocity) is decreasing, that means that the acceleration is negative.

Does fire have ways to protect itself from changes in the environment

Alexandra [31]

Answer:

I think no because the critical properties distinguishing life is adaptation to changing environment and self replication of the information encoding the life process. Fire does not change its process to adapt to its environment, e.g. moving toward more fuel or storing and conserving fuel when it is in short supply.

Hope this help you!:)

Plz I really need this question!!!!

saw5 [17]

I have a hunch that you've got the question totally covered, and what you actually need is the answer.

Kinetic energy = (1/2) (mass) (speed²)

Multiply each side by 2 : 2 x KE = (mass) ( speed²)

Divide each side by (mass): Speed² = 2 x KE / mass

Square root each side: Speed = √(2 KE/mass)

Look at that ! The question GIVES you the KE and the mass. All you have to do is plug those 2 numbers into the right side of that equation, turn the crank, do the arithmetic, and the speed falls out.

I get 200 m/s . You need to check my work.

(IF that's correct or anywhere close, it's equivalent to something around 447 miles per hour, which is very reasonable for a cruising airliner.)
