Answer:

The correct answer is D. By presenting data that contradicts those conclusions

Explanation:

Criticizing in science must be supported by data which validates the alternative conclusion. If a scientist want to demonstrate that another scientist is wrong about a conclusion- o that there are some aspects to improve- he or she has to present valid data and elaborate a new conclusion. It is like presenting evidence in a case.

density of a piece of ebony wood is 1.174 g/ml. what is the volume in quarts of a 2.1549 lb piece of this ebony wood?
lapo4ka [179]

0.88qt

Explanation:

Given parameters:

Density of ebony wood = 1.174g/ml

Mass of wood = 2.1549lb

Unknown:

Volume of the wood in quarts = ?

Solution:

Density is defined as the mass per unit volume of a substance.

Mass is the quantity of matter the wood contains.

Volume is the space it occupies.

To solve this problem, convert the mass form pounds into grams and plug into the density equation to find volume.

Then convert the volume from mL to quarts.

 Density = \frac{mass}{volume}

 Volume = \frac{mass}{density}

    1 pound = 453.592g

   2.1549 lb =  2.1549 x 453.592 = 977.5g

Volume = \frac{977.5}{1.174} = 832.6mL

     1 quart = 946.353mL

        Therefore 832.6mL x \frac{1qt}{946.353} = 0.88qt

An isotope of carbon has 8 neutrons. What is the correct hyphenated symbol for this isotope?
Rom4ik [11]

Answer:

Carbon-14 or C-14

Explanation:

Since the isotope is a carbon isotope, it means the the atomic number of the isotope is 6.

The atomic number of an element is the proton number.

Therefore, the isotope has a proton number of 6

Now we need to obtain the mass number of isotope in order to write the symbol of the isotope. This is illustrated below:

Mass number = Proton +Neutron

Proton = 6

Neutron = 8

Mass number = 6 + 8

Mass number = 14

Therefore, the symbol of the isotope is carbon-14 or C-14
