Answer:

A carbon-14 atom has 6 protons, 8 neutrons and 6 electrons. The number 12 or 14 in the name of carbon-12 and carbon-14 refers to their atomic mass.

Explanation:

Those atoms that have the same "atomic number" but differente "atomic mass" (or atomic weight) are called isotopes.

Atomic number indicates the amount of electrons that an atom has, which matchs with the number of protons it has.

Atomic mass indicates the sum of protons and neutrons that an atom has.

<u>Example with carbon-12:</u>

carbon atomic number = 6 (find this information in a periodic table)

electrons= 6

protons= 6

carbon atomic mass = 12 (find this information in a periodic table)

neutrons= atomic mass - number of protons= 12-6 = 6 neutrons

<u>Using the same analysis for carbon-14:</u>

carbon atomic number = 6

electrons= 6

protons= 6

carbon atomic mass = 14

neutrons= atomic mass - number of protons = 14-6 = 8 neutrons

In this way, carbon-14 is an isotope of carbon-12 because carbon-14 has the same atomic number than carbono-12 but different atomic mass.

An isotope of carbon always has 6 protons - that is the part of the atom which shows it is carbon. If it had a different number of protons, it would be a different element altogether

Hemoglobin (Hb) can be viewed as having two quaternary states, a low oxygen affinity state (T), and a high oxygen affinity state

natta225 [31]

<h3><u>Answer;</u></h3>

The statements that are True are;

Upon binding a molecule of oxygen, Hb undergoes a conformational change that makes the binding of subsequent O2 molecules easier.
The conformational change induced in Hb upon binding oxygen is the result of a small movement (0.2 Å) of the iron cation in the center of heme.
Site-directed mutagenesis studies have indicated that the cooperativity of O2 binding in Hb is attributable to the movement of the F helix in Hb.

<h3><u>Explanation</u>;</h3>

Hemoglobin is a key pigment in the blood that transports oxygen gas to all the tissues in the body. It is made up of two types of chains; that is two alpha chains and two beta chains.
in its deoxygenated state hemoglobin has a low affinity for oxygen compared to myoglobin. When oxygen is bound to the first subunit of hemoglobin it leads to subtle changes to the quaternary structure of the protein. This in turn makes it easier for a subsequent molecule of oxygen to bind to the next subunit.

Calculate the rcf (recipe conversion factor) for a new yield of 80 oz. (5 lbs) blueberry muffin batter. the original yield of th

SCORPION-xisa [38]

The rcf (recipe conversion factor)= 0.6

<h3>What is the rcf (recipe conversion factor)?</h3>

The conversion factor approach is the most typical technique for modifying recipes.
Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.

The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).

How this is calculated?

Conversion Factor = New Yield ÷ Old Yield

=80/134

=0.5970

=0.6(rounded to nearest tenth)

What is the total energy needed to boil 255 grams of water, given that the

nexus9112 [7]

Answer:

<u>575,000 J</u>

Explanation:

<u>1) Convert the mass of water into number of moles</u>

Molar mass of water: 18.015 g/mol

Number of moles, n = mass in grams / molar mass

n = 255 g / 18.015 g/mol = 14.15 mol

<u>2) Use the formula E = n × ΔH vap</u>

This is, you have to multiply the molar ΔH vaporization by the number of moles to find the total energy to boil the given amount of water.

E = 14.15 mol × 40,650 J/mol = 575,395.5 J

<u>3) Round to the correct number of significant figures.</u>

The mass of water is the measurement with the least number of significant figures (3), so you must report the answer with 3 significant figures,

E = 575,000 J ← answer
