If NADH from glycolysis is missing then, glycolysis will not be able to continue.
As they return to glycolysis or the citric acid cycle, these low-energy molecules pick up more high-energy electrons that allow the process to proceed. If NAD+ is not present to pick up electrons as the reactions progress, neither glycolysis nor the citric acid cycle can occur.
The method by which glucose is metabolized to produce energy is known as glycolysis. It generates water, ATP, NADH, and two pyruvate molecules. There is no need for oxygen for the process, which occurs in a cell's cytoplasm.

El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.
Answer:
La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad
Explanation:
El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.
how many moles of water is 5.02 x 10 18 molecules of water
Answer:
8.334×10^-6 moles
Explanation:
a mole is 6.023×10^23
5.02×10^18 ÷ 6.023×10^23=8.33×10^-6
so there are 8.33×10^-6 moles of water in 5.02x10^18 molecules of water
The number of moles of water in which 5.02 × 10¹⁸ molecules of water is present is 8.33 × 10⁻⁶.
What is moles?
Moles is a unit which is used to tells about the quantity of any substance, in one moles of any substance 6.023 × 10²³ number of atoms of that substances are present.
In 1 mole of water = 6.023 × 10²³ number of molecules of water is present
So, number of 5.02 × 10¹⁸ molecules of water present in how many moles will be calculated as:
Required moles = 5.02 × 10¹⁸ / 6.023 × 10²³ = 8.33 × 10⁻⁶
Hence, required moles is 8.33 × 10⁻⁶.

Calculate the volume of 150kg of chlorine gas at room temperature and pressure. The volume of one mole of gas at room temperature and pressure is 24.0dm^3. Relative formula mass (Mr): Cl2=71
Answer:
Given mass 150 kg= 150000 gram
molar mass 71 gram
number of moles = given mass/molar mass
= 2112.76 moles
1 mole = 24 Dm³
2112.76 mole =24×2112.76= 50706.24 Dm³
The volume of the mole of gas at room temperature and pressure is 50,704.08dm³
We need to first calculate the number of moles of Chlorine gas (Cl₂)
Number of moles = Mass/Molar mass
Given the following parameters
The molar mass of Cl₂ = 71g/mol
Mass of chlorine gas = 150kg = 150,000g
Get the number of moles
[tex]n=\frac{150,000}{71}\\n=2,112.67moles\\[/tex]
Given that volume of 1 mole at STP = 24.0dm³
2112.67 moles = x
Get the volume of the chlorine gas at STP.
Volume of Cl₂ at STP = 24 × 2112.67
Volume of Cl₂ at STP = 50,704.08dm³
Hence the volume of the mole of gas at room temperature and pressure is 50,704.08dm³

Which phrase best describes an individual organ?
O A. The simplest unit of life
O B. Made of different kinds of tissues
C. Made of one kind of cell
O D. Meets all the needs of an organism
Answer:
made of different kinds of tissues
Explanation:
cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism
1. the simplest unit of life - cell
2. a individual organ - would be made of different kinds of tissues
3. tissues - would be made of one kind of cell
4- an organ system - meets all the needs of a organism
also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

These data are blank with the law of conservation of mass because the mass of reactants blank the mass of products. the mass of products.
Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products , Thus results are in accordance with the law of conservation of mass.

1. What pressure would be exerted by 46.0grams of hydrogen gas placed into a 3.00 L container at
25°C?
Answer:
187.34 atm
Explanation:
From the question,
PV = nRT.................. Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
make P the subject of the equation
P = nRT/V.............. Equation 2
n = mass(m)/molar mass(m')
n = m/m'............... Equation 3
Substitute equation 3 into equation 2
P = (m/m')RT/V............ Equation 4
Given: m = 46 g, T = 25°C = (25+273) = 298 K, V = 3.00 L
Constant: m' = 2 g/mol, R = 0.082 atmL/K.mol
Substitute these values into equation 4
P = (46/2)(0.082×298)/3
P = (23×0.082×298)/3
P = 187.34 atm

molar masses: C8H18 = 114.3 g/mol O2 = 32.0 g/mol CO2 = 44.0 g/mol H2O = 18.0 g/mol
Answer:
38.7 g

2C₈H₁₈ + 25O₂ → 16CO₂ + 18 H₂OFirst we convert 27.3 grams of C₈H₁₈ into moles, using the given molar mass:
27.3 g C₈H₁₈ ÷ 114.3 g/mol = 0.239 mol C₈H₁₈Then we convert 0.239 moles of C₈H₁₈ into moles of H₂O, using the stoichiometric coefficients of the reaction:
0.239 mol C₈H₁₈ * [tex]\frac{18molH_2O}{2molC_8H_{18}}[/tex] = 2.151 mol H₂OFinally we convert 2.151 moles of H₂O into grams, using water's molar mass:
