Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet

Sample Response: The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction

Kinetic and potential energy are two types of energy that relate too
Marysya12 [62]

Answer:

Option B. A tractor–trailer traveling at 80 kph.

Explanation:

Kinetic energy can be defined as the energy possessed by a body in motion. Mathematically, it is expressed as:

K.E = ½mv²

Where:

K.E is the kinetic energy.

m is the mass of the object.

v is the velocity of the object.

From the equation, K.E = ½mv²,

We can say that the kinetic energy (K.E), is directly proportional to both the mass (m) and square of the velocity (v). This implies that the greater the mass of an object, the greater the kinetic energy and the smaller the mass, the smaller the kinetic energy.

Now, considering the options given in question above, it is evident that the tractor–trailer has a greater mass than the car, cheetah and motor cycle. Hence, the tractor–trailer will have a greater kinetic energy even though they are traveling with the same velocity.

Which property of sulphuric acid makes it suitable to use as a catalyst for the preparation of esters?​
lions [1.4K]
In Fisher esterification, sulfuric acid is used as a catalyst and its function is to convert the carboxylic compound in its conjugate acid. This favours the nucleophilic attack of the alcohol. To act as a catalyst you need a strong acid, therefore sulphuric acid is suitable for this kind of reaction.

A scientist measures the weights of two different animals. One is 250 grams. The other is 330 grams. In milligrams, what is the
Stolb23 [73]
The way you would answer this is convert the grams to milligrams (g to mg) that would give you 330,000mg and 250,000mg then subtract them

Remember 1g = 1000mg
