If an organism ingests 950.0 g of glucose (C6H12O6) in its lifetime, how many grams of carbon dioxide (CO2) will be released? (molar mass C6H12O6 = 180.156 g/mol) (molar mass CO2 = 44.009 g/mol)
Answer:
1392. g CO2
Explanation:
Se disuelven 10 g de acido carbónico H2CO3 en 150 g de agua. Determina la concentración % m/m de esa disolución?
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100[/tex]
Substitute the values into above formula as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100\\= \frac{10 g}{150 g} \times 100\\= 6.66%[/tex]
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
How many moles are in 8.0 gram sample of C3H4
Answer:
0.18 mol C₃H₈
Explanation:
to find the mole you have to convert the 8.0grams into moles.
8.0g C₃H₈ 1 mol C₃H₈
1 44.0g C₃H₈
*Pretend that those are a table*
I got 44.0g because Carbon is 12.0g you multiply that 3 times because it has a subscript of 3 and do the same for Hydrogen (1.0 x 8) then add those which would be 44.0g.
1 mol of C₃H₈ = 44.0g C₃H₈
now just mulitply and divide them.
8.0g x 1 = 8.0
1 x 44.0g = 44.0
8.0/44.0 = 0.18 mol C₃H₈

Si 4 L de un gas están a 0,79 atm de presión, ¿Cuál será su nuevo volumen, si aumentamos la presión hasta 1,05 atm?
Respuesta:
3 L
Explicación:
Paso 1: Información provista
Volumen inicial del gas (V₁): 4 LPresión inicial del gas (P₁): 0,79 atmVolumen final del gas (V₂): ?Presión final del gas (P₂): 1,05 atmPaso 2: Calcular el volumen final del gas
Si suponemos que el gas se comporta como un gas ideal y que la temperatura permanece constante, podemos calcular el volumen final del gas usando la ley de Boyle.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0,79 atm × 4 L / 1,05 atm = 3 L

Explanation:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula.
Substances formed as a result of a chemical reaction are calledImmersive Reader (1 Point) products reactants catalysts precipitates
Answer: substances formed as a result of chemical reaction are called PRODUCTS.
Explanation:
A chemical reaction can be defined as a reaction in which substances known as the REACTANTS makes or breaks it's bonds to form another substance usually referred to as the PRODUCT. Usually, a new substance which is referred to as the product that is formed is different from the original reacting substances. Some of the characteristics of a chemical reaction include:
--> colour change,
--> heat production,
--> precipitation
The rate at which these chemical reaction occurs depends on some factors such as pressure, temperature and concentration of the reactants
There are different examples of chemical reaction which includes:
--> Rusting of iron: this occurs when iron and oxygen combines to form a mixture of iron oxides, which is the product of the chemical reaction.
--> The burning of magnesium in air: in this Chemical reaction, magnesium reacts with oxygen to form magnesium oxide which is the product of the chemical reaction.
2Mg(s) + O2(g) △→ 2MgO(s)
--> Production of table salt: this is formed from the reaction of sodium and chloride to give sodium chloride as the product of the chemical reaction.
Therefore in a chemical reaction, no atom is destroyed or created but a new PRODUCT is formed from reactants.

A 32.9-mL sample of Ba(OH)2 is titrated with HCl. If 37.2 mL of 0.863 M HCl is needed to reach the endpoint, what is the concentration (M) of the Ba(OH)2 solution
Answer:
[tex]M_{base}=0.488M[/tex]
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by firstly writing the chemical reaction between hydrochloric acid and barium hydroxide:
[tex]2HCl+Ba(OH)_2\rightarrow BaCl_2+2H2_O[/tex]
It means there is 2:1 mole ratio of the acid to base, and we are able to write the following mole ratio, then written in terms of volumes and concentrations:
[tex]n_{acid}=2n_{base}[/tex]
Thus, we obtain the following:
[tex]M_{acid}V_{acid}=2M_{base}V_{base}[/tex]
Then, we solve for the concentration of the base and consequently plug in the given data to obtain:
[tex]M_{base}=\frac{M_{acid}V_{acid}}{2V_{base}} \\\\M_{base}=\frac{0.863M*37.2mL}{2*32.9mL}\\\\M_{base}=0.488M[/tex]
Regards!
How much concentrated 15.54 M sulfuric acid is need to prepare 6.1 mL of a 2.28 M solution?
Answer:
0.895 mL
Explanation:
Using the formula;
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (mL)
V2 = final volume (mL)
According to the information provided in this question;
C1 = 15.54M
V1 = ?
C2 = 2.28M
V2 = 6.1 mL
Using C1V1 = C2V2
V1 = C2V2 ÷ C1
V1 = (2.28 × 6.1) ÷ 15.54
V1 = 13.908 ÷ 15.54
V1 = 0.895 mL
1. Calculate the mass of 1.000 mole of CaCl2
Show all your work. Answer in scientific notation when applicable.
Answer: 110 g/mol
Explanation:
First we need to find the molar mass of CaCl2 using the periodic table:
Ca: 40
Cl: 35 (Since Cl has a 2 at the end, multiply 35 by 2)
70+40= 110
Then multiply by amount of moles
110g×1.000mol = 110 g/mol
