Answer:
[tex] H_2SO_4 [/tex]
Explanation:
In the first option, the compound [tex] HClO_3 [/tex] has 1 hydrogen atom and 3 Oxygen atoms. There are 3 times as many oxygen atoms as hydrogen atoms.
In the second option, the compound [tex] H_2SO_4 [/tex] has 2 hydrogen atom and 4 Oxygen atoms. That is 2:4 = 1:2. Therefore, there are twice as many oxygen atoms as hydrogen atoms.
In the third option, the compound [tex] H_2O [/tex] has 2 hydrogen atoms and 1 Oxygen atom. There are ½ times as many oxygen atoms as hydrogen atoms.
In the fourth option, the compound [tex] H_3PO_4 [/tex] has 3 hydrogen atoms and 4 Oxygen atoms. 4 oxygen atoms to 3 hydrogen atoms.

: Research coal and natural gas as a source of energy.
Answers
Answer:
Its fossil energy non renewable source
Explanation:
Answer:
Coal vs Natural Gas Coal is a sedimentary rock with a high concentration of hydrocarbons and carbon. Given that it takes millions of years for coal to develop, it is categorized as a nonrenewable energy source. Coal is combustible and typically black or brownish black in color. Natural gas is a naturally occurring mixture of gaseous hydrocarbons, mostly methane, with small traces of other higher alkanes. Coal and natural gas have different benefits, effects on the Earth, and impacts on human health. Natural gas is a fossil fuel; however its global warming emissions are significantly smaller compared to those from coal or oil. When combusted in a modern, efficient natural gas-power plant, natural gas releases between 50 and 60 percent less carbon dioxide (CO2) than pollution from an average modern coal plant. The impacts of human health due to air pollution from both coal and natural gas can lead to asthma and breathing issues, brain damage, heart problems, cancer, neurological disorders, and early mortality. These conditions are from the releasing of mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and other heavy metals in to the air. In 2021, electricity producers in the United States paid roughly $4.98 per million British thermal units for natural gas. Coal power plant operators, on the other hand, paid an average of 1.98 US dollars; in simpler terms, the cost of generating electricity is cheaper using coal. Coal is a reliable, cheap source of power. It is easy to store, reduces dependence on oil, and creates many jobs. On the other hand, when burned to create power, natural gas produces roughly half the carbon dioxide (CO2) and one-tenth the air pollutants produced by coal. By using gas instead of coal, there is significant potential to cut near-term CO2 emissions and air pollution by using gas over coal. It is adaptive. A gas-fired power plant starts and stops much faster than a coal-fired unit. Both gas and coal have plentiful pros and cons however gas is the better one to use. Gas is more abundant and pollutes more than coal. Though coal is cheaper, the effects on the environment and human health are not worth the gamble. https://www.shell.com/energy-and-innovation/natural-gas/natural-gas-and-its-advantages.html http://groundtruthtrekking.org/Reports/Coal-Electricity-Prices-Externalities-Analysis/1/Coal-Electricity-Prices-Externalities-Levelized-Cost/ https://www.statista.com/statistics/189180/natural-gas-vis-a-vis-coal-prices/

Answers
knowing what you know about how a substance travels in diffusion in order for carbon dioxide to leave the blood and enter the alveoli there would be higher or lower concentration of carbon dioxide
Answers
Answer:
CO2 moves down its concentration gradient by simple diffusion. Therefore, CO2 would have to be high in the blood, and low in the alveoli for simple diffusion to happen, this would be done by passive diffusion and thus, simple diffusion.
Remember that in simple diffusion you go from an area of a high concentrated solute towards an area of low concentrated solute.

Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL

Answers
Answer:
Sedimentary rocks are made of sand, gravel, mud and other materials. They go through a 5 step process to be made.
Explanation:
1) first weathering breaks down material that will be used to form the rock.
2) next erosion picks up the sediment via wind, water, or glacier
3) the sediment is then transported via wind, water, or glacier
4) Then deposition occurs. (depositing the sediment)
5) Lithification (turning the sediment to rock)

Your colleague asks you to verify her findings about a new polymer intended for use as a vascular graft. It must be reasonably elastic; otherwise, the blood will be constricted and increase its flowrate downstream with each pulse of the heart. She found that the material was sufficiently elastic for use inside the body. After running a tension test, you find that it is too brittle for use. Your colleague reviews your protocol and declares that you have either graduated from Duke or checked your eyelids for light leaks during Dr. Brudno's BME 203 class, because it definitely is adequate. Describe two mistakes you may have made. Put a (1) and (2) before each of your reasons.
Answers
Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.

Fun fact ; I made this sentence while brushing my teeth , you can tell with how this sentence is lowercased and multiple typos
Answers
Answer:
A non-renewable source of energy is coal.
Explanation:
The mineral coal is a brown or black rock, of sedimentary origin, that comes from organic matter, so it is considered a fossil fuel.
Currently, coal is used as an energy source, since its combustion produces a great amount of heat. However, the speed with which coal is consumed is faster than its production —which can last millions of years— so it is considered a depletable or non-renewable energy source.
The other options, such as hydroelectric, solar and wind energy are renewable energy sources.

Each parent gives one of these to the offspring to form a genotype.
Answers
Answer: Alleles
Explanation: Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Each parent gives one ALLELE to the offspring to form a genotype.
An allele is a gene variant. which is inherited from each parent.
During fecundation, each parental gamete provides a different allele of a given gene/locus in order to form the genotype of an individual.
If both parents provide the same allele of a given gene/locus, then the individual is homo-zygous for that gene.
If both parents provide different alleles of a given gene/locus, then the individual is heterozygous for that gene.
In conclusion, one allele is inherited from the mother and the other allele from the father.

What is a possible result of an increased amount of CO2 in the atmosphere?
Answers
Answer:
There are no options to this question, however, it can be answered using general knowledge. The answer is GLOBAL WARMING
Explanation:
Carbon dioxide, commonly called CO2, is one of the gaseous constituent of air. It is considered to be the most important greenhouse gas i.e. gases that have the ability to trap heat from the surrounding atmosphere. Due to this ability, CO2 in addition to other gases like methane are known to contribute to a phenomenon called GLOBAL WARMING.
GLOBAL WARMING is an increase in the atmospheric temperature of the Earth due to the effect of greenhouse gases. Global warming is a concern for the world populace, hence, an increase in the concentration of gases like CO2 in the atmosphere will lead to GLOBAL WARMING (an increase in Earth's atmospheric temperature).
