What do the conclusions tell about the experiment?
Blababa [14]

Answer:

Option C

Explanation:

When you perform a experiment to test your hypothesis (your educated guess on what you think will happen) you complete trials to find data that is reliable and valid so you are only getting the best possible results. After you complete the experiment you write your conclusion which is when you take the data and you say if the data supported your hypothesis, if you did guess correctly at the beginning of the experiment. Which means the answer is option C "the conclusions tell why the data support or reject the hypothesis."

Hope this helps.

3) Explain the working principle of catalyst for both rate of reaction and equilibrium reaction . show by means of graphical rep
victus00 [196]

Explanation:

A catalyst has no effect on the equilibrium state, but it enables equilibrium to be reached more quickly by decreasing the “energy of activation”. In fact, a catalyst affects forward and reverse rates equally.

A gold nugget has a density of 38.6g/cm3 and a mass of 270.2. what is its volume?​
aivan3 [116]

Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.


In this problem, we have density and we have mass so we can plug into the equation and solve for V.

38.6=270.2/V

<em>*Multiply both sides by V*</em>

38.6V=270.2

<em>*Divide both sides by 38.6*</em>

V=7


The volume of the gold nugget is 7cm3.


Hope this helps!!

How many hydrogen atoms are missing in ethane compared to ethane
Lera25 [3.4K]

Isomer types. The connectivity and molecular motion due to bond rotations within a molecule can result in atoms that are considered to be equivalent or non-equivalent types. For example, the six hydrogen atoms in ethane are considered to be chemically equivalent
