His first prototype was simply an airtight, watertight pouch containing 40 g of ammonium chloride (NH4Cl). He added 100 mL of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water. He tested his prototype by measuring the temperature of the bottle of water over time. Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results. Maximum Cooling Achieved ___________________________________________ trial 1 2 3 4 5 6 7 ___________________________________________ grams of NH4Cl 30 40 50 50 60 70 80 ___________________________________________ amount (mL) of water added 100 100 100 150 150 200 200 ___________________________________________ greatest temperature change (–°C) 3.6 4.3 4.3 4.8 5.2 5.6 5.8 ___________________________________________ Finally, Rodrigo held the amount and concentration of the solution constant while trying different amounts of insulation.

Explain solar flares and how it affect earth

Answers

A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most every wavelength of the spectrum. The primary ways we monitor flares are in x-rays and optical light. Flares are also sites where particles (electrons, protons, and heavier particles) are accelerated.
Solar flares impact Earth only when they occur on the side of the sun facing Earth. Because flares are made of photons, they travel out directly from the flare site, so if we can see the flare, we can be impacted by it.Coronal mass ejections, also called CMEs, are large clouds of plasma and magnetic field that erupt from the sun. These clouds can erupt in any direction, and then continue on in that direction, plowing right through the solar wind. Only when the cloud is aimed at Earth will the CME hit Earth and therefore cause impacts.

ASAP HELP 100 POINTS Which describes nuclear fission? starts when two atoms slam together, causing the larger atom to split into two smaller atoms

starts when a neutron slams into an atom, causing two atoms to form one, heavier atom

starts when two atoms slam together to form one, heavier atom


starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms

Answers

The statement that describes nuclear fission is as follows:

  • Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.

Thus, the correct option for this question is D.

What is Nuclear fission?

Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.

Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.

Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.

If a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the offspring have?A.Rw
B.RW
C.rW
D.rw

Answers

B. RW. Whenever something is dominant the letter will always be capitalized on a punnet square. Since both given animals are homozygous dominant then the answer should all be in capital letters. Since there are no recessive parents which is represented by lowercase letters.
it is b.rW since they both dominant

Which of the following accurately reflects the beliefs on Earth's early history?a. Scientists believe that microspheres nearly prevented the development of early life.
b. Scientists believe that DNA may have existed before RNA.
c. Scientists believe oxygen was plentiful in the early atmosphere.
d. Scientists believe the early atmosphere lacked the oxygen necessary to support modern human life.

Answers

The correct answer is D.
From the scientific research conducted so far, we know that in the early Earth's history the atmosphere lacked oxygen and was mostly filled with other gases like methane. The increase in oxygen levels happened when the plants started producing oxygen as a byproduct of the process of photosynthesis.
The research so far also shows that the RNA was present before the DNA and that the microspheres might have been essential to the development of life on Earth.
Correct answer is D.

What is a reducing sugar?

Answers

Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.

Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.

Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
