When carbon dioxide enters the blood, some of it combines with ____________ to form carbaminohemoglobin, but most of it becomes ____________ ions that diffuse into the blood plasma.
Answer:
hemoglobin to become bicarbonate
Explanation:
When carbon dioxide enters the blood it combines with hemoglobin to form carbamino hemoglobin or carboxyhemoglobin but most of it becomes carbonate ions and diffuse into the blood plasma.
What is carboxyhemoglobin?Hemoglobin is a blood protein giving red colour to the blood. It helps to transport oxygen everywhere. When oxygen fills in the air sack, it combines with oxygen and form oxyhemoglobin.
However, hemoglobin have more affinity towards carbon dioxide and and they combines to form carbaminohemoglobin which prevents the transportation of oxygen through blood.
The carbon dioxide will be converted into carbonic acid by combining with water. This acid then forms its carbonate ions and these ions helps to maintain the blood pH to be constant.The carbonate ions, CO₃²⁻can easily diffuse into blood plasma.

How many protons?
Electrons?
Answer:
Nitrogen has 7 protons and 7 electrons and 7 neutrons.
Explanation:
The atomic number of an element is the number of electrons and protons they have. The atomic mass - the atomic number of an element equals the number of nuetrons. The atomic mass of nitrogen is 14 and the atomic number is 7 therefore we have to subract, 14-7=7.

Based on the periodic table, what is the oxidation number of oxygen (Group VI, period 2) in compounds? a) 0 b) +2 C) -2 d) 1
The oxidation number of oxygen (Group VI, period 2) is -2.
The electrical charge of an atom describes its Oxidation number.\The number of electrons that must be gained or lost in an atom's valence electron shell to make it to be filled or half-filled gives us the oxidation number value.When the atom gains electrons,it acquires a negative oxidation number. When the atom loses electrons,it acquires a positive oxidation number
Oxygen has 8 electrons with {He] 2s² 2p⁴ configuration. With 6 electrons in its valence shell, it need to gain 2 electrons to achieve stability, When it gains 2 electrons, it acquires a negative oxidation number of -2.

Apply the fertilizer.
Answer:
AbstractOrganic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance.

5. How could you use Kepler's 3rd Law to find the relationship between all of the
moons of Jupiter?
Answer:
essentially through the use of keplers 3rd law comparing the proportionality of a planets squared versus cubed orbital patterns you can determine how fast a planet will orbit something and complete a full orbit
Explanation:
Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi-major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit. (from NASA)
A compound is 2. 00% H by mass, 32. 7% S by mass, and 65. 3% O by mass. What is its empirical formula? The first step is to calculate the mass of each element in a 100-g sample of the compound. We use 100 g because it makes the calculations more straightforward. What is the mass of each element in a 100. 0-g sample of the compound? mass H = g mass S = g mass O = g.
Answer:
We assume that there is 100g of the compound (because it makes it easier to calculate) and we turn the percentages into grams.
2% of Hydrogen = 2g of H
32.7% of Sulfur = 32.7g of S
65.3% of Oxygen = 65.3g of O
Now we change the mass of these elements to moles by dividing the mass by the molar mass (which is the value of atomic mass on your periodic table)
2g/1.01g = 1.98 mol
32.7g/32.06g = 1.02 mol
65.3g/16g =4.08 mol
divide all these mol values by the smallest mol value, which is 1.02. (Round the values to whole numbers)
1.98/1.02 = 2 (rounded) of Hydrogen
1.02/1.02 = 1 of Sulfur
4.08/1.02 = 4 of Oxygen
H2SO4 (also known as sulphuric acid) is your empirical formula.

2. Calculate the heat of combustion of C6H14(l) in kJ/mol if 1.66 g of C6H14(l) were ignited in a calorimeter containing 2750. g H2O. A 3.54˚C temperature rise was observed. The calorimeter constant is 11.2 kJ/˚C. The specific heat of water is 4.184 J/g˚C.
This problem is describing the combustion experiment where by the heat of combustion of 1.66 g of liquid C6H14 can be calculated via calorimetry. The calorimeter (C=11.2kJ/°C) contains 2750. grams of water with a temperature rise of 3.54 °C, it means we can calculate the total heat released by the combustion of this hydrocarbon via:
[tex]Q_{combustion}=-(Q_{calorimeter}+Q_{water})[/tex]
Because the heat of combustion is released to the water and the calorimeter. Next, we break down each heat and subsequently plug in the given values:
[tex]Q_{combustion}=-(11200\frac{J}{\°C}*3.54\°C +2750.g*4.184\frac{J}{g\°C}*3.54\°C )\\\\Q_{combustion}=-80,379J=-80.4kJ[/tex]
After that, we calculate the moles of C6H14 by considering the given mass and its molar mass (86.18 g/mol):
[tex]n=1.66g*\frac{1mol}{86.18g} =0.01926mol[/tex]
And finally, we divide the total heat of combistion by the moles to get the heat of combustion:
[tex]\Delta H_{comb}=\frac{-80.4kJ}{0.01926mol} =4,174\frac{kJ}{mol}[/tex]
