Which flowers are prettier, daisies or roses?

zhenek [66]

Overall, it depends on your opinion. Some people think roses are prettier than daisies, and daisies are prettier than roses.

Roses are the definitive symbol for love and appreciation, while daisies are a symbol of Virgin Mary representing her chastity, grace, and purity. Daisies represent beauty and patience as well.

Formation of Sedimentary RocksLast Updated on Tue, 15 Mar 2016 | Geology

N^deS Sediments produced by weathering and erosion form sedimentary rocks through the process of lithification.

Real-World Reading Link Whenever you are outside, you might see pieces of broken rock, sand, and soil on the ground. What happens to this material? With one heavy rain, these pieces of broken rock, sand, and soil could be on their way to becoming part of a sedimentary rock.

Weathering and Erosion

Wherever rock is exposed at Earth's surface, it is continuously being broken down by weathering—a set of physical and chemical processes that breaks rock into smaller pieces. Sediments are small pieces of rock that are moved and deposited by water, wind, and gravity. When sediments become glued together, they form sedimentary rocks. The formation of sedimentary rocks begins when weathering and erosion produce sediments.

Weathering Weathering produces rock and mineral fragments known as sediments. These sediments range in size from huge boulders to microscopic particles. Chemical weathering occurs when the minerals in a rock are dissolved or otherwise cimicly changed. What happens to more-resistant minerals during weathering? While the less-stable minerals are chemically broken down, the more-resistant grains are broken off of the rock as smaller grains. During physical weathering, however, minerals remain chemically un changed.

We add a 1.20-g sample of dry ice to a 755-mL flask containing nitrogen gas at a temperature of 25.0 C and a pressure of 725mmHg

yaroslaw [1]

Answer:

Total pressure is 1396 mmHg

Explanation:

By:

PV/RT = n

It is possible to obtain the initial moles of nitrogen gas, where:

P is pressure (725 mmHg = 0,954 atm)

V is volume (0,755L)

R is gas constant (0,082atmL/molK)

T is temperature (25,0°C = 298,15 K)

Replacing:

n = 0,02946 moles of nitrogen gas.

The moles of dry ice (CO₂; molar mass= 44,01 g/mol) are:

1,20 g × (1mol/44,01g) = 0,02727 moles of dry ice.

When dry ice sublimes, total moles are:

0,02727 + 0,02946 = 0,05673 moles

With the temperature (25,0°C = 298,15 K) and volume (0,755L) it is possible to obtain total pressure, thus:

P = nRT/V

Replacing:

P = 1,837 atm × (760 mmHg/1atm) = 1396 mmHg

I hope it helps!

X-ray crystallography is used to see the structure of molecules. Scientists have used this technique to find the structure of ch

Julli [10]

Answer:

A. how cholesterol works in the body.

Explanation:

If we know the precise structure of a molecule (by X-ray crystallography), we can understand more about how it interacts with cells, proteins, and other molecules. It can also tell us what reactions it might take part in.

Therefore, we can learn more about how it works in the body and what activities it takes part in in the cells of the body.

What occurs during electrolysis? Low-energy reactants become high-energy products. High-energy reactants become low-energy produ

Nonamiya [84]

Answer:

Low-energy reactants become high-energy products.

Explanation:

In electrolysis, you are forcing a reaction to occur that otherwise wouldn't happen.

You are pumping energy into the system and converting low-energy reactants into high-energy products.

B is wrong. Nature tends to run downhill energetically, so high-energy reactants tend to form low-energy products spontaneously.

C and D are wrong. If an element is unreactive, it stays unreactive, and vice versa. You can't change the nature of an element.
