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.

When potassium metal is placed in water, a large amount of energy is released as potassium hydroxide and hydrogen gas are produced in the reaction 2K(s) + 2H2O(l) → 2KOH(aq) + H2(g). Your lab partner says this is a redox reaction and a combustion reaction. Do you agree? Defend your answer by explaining whether or not it meets the requirements of each type of reaction.
This is a redox reaction but not a combustion reaction.
Redox Reaction
A type of chemical reaction that involves a transfer of electrons or gain of electrons between two-element. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes.
Combustion reaction
It must have two products. CO2 and H2Ooxygen in the reactant is must.
∴ The reaction is Redox ✓ not combustion

What is collision theory?
A.a theory stating that reactants must collide with products in order for a chemical reaction to occur
B.a theory stating that there must be minimal kinetic energy between products for a chemical reaction to occur
C.a theory stating that a chemical reaction occurs only when reactants strike each other at the correct orientation and with sufficient kinetic energy
D.a theory stating that a chemical reaction occurs only when reactants are placed in separate containers and the containers are then placed close together
Answer:
A
Explanation:
collision theory is a theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another
What is the periodic table?
Answer:
The periodic table, also known as the periodic table of chemical elements, is a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.
Explanation:
The periodic table is a tabular arrangement of chemical elements that classifies elements according to repeating qualities and is structured by increasing atomic number. Metals are located on the left side of the table, whereas nonmetals are located on the right. The columns are referred to as groupings.

Something that potatoes and bacteria have in common is that they both reproduce(1 point)
via vegetative reproduction.
using tubers.
via binary fission.
asexually.
The things that potatoes and bacteria have in common is that they both reproduce asexually. Thus option 4 is correct.
What is reproduction?Reproduction is defined as the biological process that creates new individual organisms from existing ones, also referred to as "offspring"
It can also be defined as the process by which identically minded organisms make new organisms.
There are two types of reproduction.
Sexual reproduction - It is defined as a method of reproduction whereby male and female gametes combine to create an offspring.Asexual reproduction - It is defined as a method of reproduction that doesn't modify the number of chromosomes or involve the fusing of gametes.Thus. the things that potatoes and bacteria have in common is that they both reproduce asexually. Thus option 4 is correct.

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.
What are anions ?Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).
The electrode where reduction takes place in any electrochemical cell is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.
Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

A gas measures 140 mL at 400 K find its volume at 120 K if the pressure remains constant.
By applying Charles law, the final volume of the gas is equal to 42 mL.
Given the following data:
Initial volume = 140 mLInitial temperature = 400 KFinal temperature = 120 KTo find the final volume of the gas, we would apply Charles law:
Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]
Where;
T is the temperature of an ideal gas.V is the volume of an ideal gas.Substituting the given parameters into the formula, we have;
[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]
Final volume = 42 mL.

Beryllium (Be) has four electrons. Fluorine (F) has nine electrons. Which chemical formula shows the correct subscripts for the product of the reaction when beryllium and fluorine combine
Answer:
BeF2
Explanation:
The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.
The valence electron of an atom determines how an atom goes into bonding.
Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.
Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.
The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.
This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

Blood has a mass-volume percent of NaCl of 0.9%. What mass (g) of NaCl is present in a liter of blood
The mass (g) of NaCl that is present in a liter of blood is 0.347g.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the decimal mass-volume of the substance by its molar mass. According to this question, Blood has a mass-volume percent of NaCl of 0.9%. This means that 0.9/100 = 0.009g of NaCl is present in each 100g of blood. Molar mass of NaCl = 23 + 35.5 = 38.5g/molMass of NaCl in a liter of blood = 38.5 × 0.009Mass of NaCl in a liter of blood = 0.347g of NaCl.
