Chemistry
1 answer:
kodGreya [7K]2 years ago

Answer:

\boxed {\tt d\approx 2.7 \ g/cm^3}

Explanation:

Density can be found by dividing the mass by the volume.

d=\frac{m}{v}

The mass of the marble slab is 4.24 kilograms.

The density is 1564 cubic centimeters.

Since we want to find the density, in g/cm^3, we must convert kilograms to grams. There are 1000 grams in 1 kilogram, so multiply 4.24 by 1000.

  • 1000 g= 1 kg
  • 4.24*1000=4240 grams

Therefore,

m= 4240 \  g \\v= 1564 \ cm^3

Substitute the values into the formula.

d=\frac{4240 \ g}{1564 \ cm^3}

Divide.

d= 2.71099744 \ g/cm^3

Round to the nearest tenth. The 1 in the hundredth place tells us to leave the tenth place as is.

d \approx 2.7 \ g/cm^3

The density is about 2.7 grams per cubic centimeter.

Why didn't mendeleev use atomic number to arrange the elements?
Pepsi [2]

The primary reason for this was that Mendeleev didn't know that atomic numbers actually existed. Atomic numbers were only discovered a period after Mendeleev's time. The use of X-rays made it possible to find the atomic number, and those had not been discovered yet. <span>
<span>The periodic table was then arranged in 1913 by Henry Moseley in an arrangement according to atomic number.</span></span>

Which option accurately describes the first two stages of photosynthesis?
Lemur [1.5K]

Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.

A chemistry teacher is able to grade chemistry labs at a rate of 5 labs for every 3 minutes. They need to grade 165 labs how man
PIT_PIT [208]

Answer:

1.65hr

Explanation:

Given parameters:

Number of labs  = 5 labs

 Time taken  = 3 minutes

Unknown:

Time taken in hours to grade 165 labs  = ?

Solution:

Let us find the rate of the teacher;

  Rate  = \frac{number of labs}{time}  

  Insert the parameters and solve;

   Rate  = \frac{5}{3}   = 1.67labs/min

Now;

   Time to grade 165 labs  = \frac{number of labs}{rate}  

   Time to grade 165 labs  = \frac{165}{1.67}   = 98.8min

  Since;

               60min = 1hr

               98.8min  = \frac{98.8}{60}   = 1.65hr

Robert has pure samples of both D-ribose and D-arabinose, but he forgot to label them. He only has some nitric acid, the reagent
Sauron [17]

Answer:

Following are the responses to the given question:

Explanation:

Since HN03 is an oxidation substance D-ribose u.ith oxidized to form in rubric acid Ribose is chiral, but rubric acid is achiral because of its symmetry mirror level, Hence no infrared roster in the sample holder is observed.

Please find the attached file.

D-Arabinose, on either hand, gives optical aldaric acid with such a net optical rotation observed inside the polarimeter for diagnosis with HN03.

What 2 pieces of equipment will you use to separate the salt from the water?
uysha [10]

Separate Salt and Water Using Distillation

If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

hope this helps!!
