Answer:
The number of ATP molecules produced during the anaerobic phase of cellular respiration is 32 ATP.
Explanation:
Actually it's 36 ATP
8 from glycolysis
6 from pyruvate
24 from Krebs cycle
So total are 38 ATP but 2 ATP are consumed during glycolysis so total will be 36.

The charge on the cobalt ion in the salt CoO is ________.
Answer:
The charge of cobalt in the salt is + 2.
Explanation:
The charge of the salt = 0 . This is because it is neutral.
Charge of cobalt = ?
Charge of oxygen = -2 (This is a constant value, it is -2 only in peroxides)
Charge of salt = Charge of cobalt + Charge of oxygen
0 = x + (-2)
x = + 2

what is the base unit×1000?
The SI unit of temperature is the kelvin (K), which spans the same temperature change as the degree Celsius. The Kelvin scale is a thermodynamic scale, meaning that its zero point is at absolute zero rather than the freezing point of water. The second reference point for this scale as it is currently defined is the triple point of water, which is a unique point on the phase diagram of water (a specific combination of pressure and temperature) where ice, liquid water and water vapor are all in equilibrium. The triple point is assigned the temperature of 273.16 K.
The old centigrade scale used the freezing and boiling temperatures of water as its reference points, with one degree centigrade equal to 1/100 of the temperature span between the freezing and boiling points of water. The definition of the Kelvin scale was chosen to make the kelvin the same size as the centigrade degree.
The Celsius scale is defined in terms of the Kelvin scale but is equivalent to the old centigrade scale, which it replaces. It is convenient for reporting weather and cooking temperatures and so on, but is not particularly useful for scientific purposes. For instance, the behavior of gases which approximate ideal gases is such that at zero degrees C they experience a volume change of 1/273 for a one degree change in temperature. This observation provided one of the first indications for the value of absolute zero.
When using the ideal gas law:
PV = nRT
where P is pressure
V is volume
n is the quantity of gas in moles
R is a constant
T is the temperature
it is necessary to use a thermodynamic scale, usually Kelvin.
Another thermodynamic scale, the Rankine scale, has a relationship to the Fahrenheit temperature scale analogous to that between the Kelvin and Celsius scales.

An object is a regular, rectangular, solid with dimensions of 2 cm by 3cm by 2cm. It has a
mass of 24 g. Find its density.
Answer:
2
Explanation:
Density = mass/volume
m=24
v=2*3*2=12
24/12=2
Answer:
[tex]\boxed {\tt d= 2 \ g/cm^3}[/tex]
Explanation:
Density can be found using the following formula.
[tex]d=\frac{m}{v}[/tex]
where [tex]m[/tex] is the mass and [tex]v[/tex] is the volume.
We know the mass is 24 grams. We must find the volume.
Since it is a rectangle, the volume can be found using the following formula.
[tex]v=l*w*h[/tex]
The length is 2 centimeters, the width is 3 centimeters and the height is 2 centimeters.
[tex]v= 2 \ cm * 3 \ cm * 2\ cm[/tex]
[tex]v= 6 \ cm^2 * 2\ cm[/tex]
[tex]v= 12 \ cm^3[/tex]
Now we know the volume, and can substitute it into the density formula.
[tex]d=\frac{m}{v}[/tex]
[tex]m= 24 \ g\\v= 12 \ cm^3[/tex]
[tex]d=\frac{24 \ g}{12 \ cm^3}[/tex]
[tex]d= 2 \ g/cm^3[/tex]
The density is 2 grams per cubic centimeter.

Question you have about rocks or minerals
b.) If the half-life of Carbon-14 is 5230 years and I start with 100 grams, how long will it take for the
Carbon-14 to decay to 3.125 grams?
Answer:
26150 years
Explanation:
First we need to determine the number of half lives -- not years -- it'll take for 100g (of any element) to decay to 3.125 g
First Half Life 100/2 = 50
Seconf Half Life 50/2 = 25
Third Half Life 25/2 = 12.5
Fourth Half Life 12.5/2 = 6.25
Fifth Half Life 6.25/2 = 3.125
So it'll take 5 half lives for 100g to decay to 3.125g.
If the Half Life of Carbon-14 is 5230 and it will take 5 half lives, to determine the number of years we just need to multiply 5*5230
5*5230 = 26150
This means that it will take 26150 years for 100g Carbon-14 to decay to 3.125g.

the number of electrons in n=1 and n=2 shells of aluminum are
Answer:
n=1 holds two electrons and n=2 holds eight electrons.
Explanation:
Hello
In this case, since the atomic number of aluminum is 13, its electron configuration is:
[tex]Al^{13}: 1s^2,2s^2,2p^6,3s^2,3p^1[/tex]
In such a way, we can see that the level n=1 is filled with two electrons since the subshell s is able to hold two electrons and the level n=2 is also filled but with eight electrons as s holds two whereas p holds 6. Moreover, n=3 is holding three electrons.

Draw the product formed when 2-butanol undergoes reaction with TsCl and Et3N. CH3C6H4SO2Cl.
Answer:
Explanation:
In organic chemistry, the reaction between 2-butanol with TsCl and Et3N is known as the tosylation of the alcohol hydroxyl group. Alcohol is being changed to tosylate by the use of tosyl chloride under the influence of a base. Tosylation of alcohol is an example of a nucleophilic substitution reaction. From the image attached below, we will see how the reaction between 2-butanol proceed into the product by using tosyl chloride and a base(Et3N).

Which is the formula mass of (NH4)2SO4?
0 96.07 amu
114.12 amu
O 116.17 amu
132.17 amu
Answer:
D. 132.17 amu
Explanation:
The formula mass of a compound can be determined from the formula of the compound thus, from the number each elements present. The formula mass of (NH₄)₂SO₄ is 132.17 amu.
What is formula mass?
Formula mass of a compound is the mass calculated from its formula. Each elements has a definite mass called its atomic mass expressed in g/mol or amu.
Mass number of an element is the sum of number of its protons and neutrons. The actual mass of an element is calculated with respect to the mass of 1/12th of Carbon-12 and it is called relative mass.
Here, the atomic mass of N = 14.006 amu
mass of H = 1.008 amu.
There are 4 hydrogen thus 4 × 1.008 = 4.008 u.
The mass of two units of NH₄ is = (14.006 + 4.008) × 2
= 36.028 u.
Atomic mass of sulfur = 32.6 amu
atomic mass of oxygen = 15.9 amu.
Thus for 4 oxygens = 15.9 × 4 = 63.6 u
The mass of SO₄ unit = 32.06 + 67.6 = 96.2u
Thus the total mass of (NH₄)₂SO₄ = 96.2 + 36.028
= 132.17 amu
Hence, the formula mass of (NH₄)₂SO₄ is 132.17 amu. Thus, option D is correct.

Which of the following is true for all chemical reactions? The total mass of the reactants increase. The total mass of the products is greater than the total mass of the reactants. The total mass of the products is less than the total mass of the reactants. The total mass of the reactants equals the total mass of the products.
Answer:
The total mass of the reactants equals the total mass of the products.
Explanation:
The true statement for all chemical reactions is that the total mass of the reactants equals the total mass of the products.
What is chemical reaction?Chemical reactions are those reactions in which reactants react with each other and converted into products for the completion of the reaction.
Let us assume a chemical reaction:
A + B → C + D
Where, A & B are reactants which are converted into products C & D. Means mass of reactants will convert into the mass of products as it follows the law of conservation of mass.
So, total mass of the reactants equals the total mass of the products.
