Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answers
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.

A gas has a solubility of 1.46 g L at 8.00 atm of pressure. What is the pressure of a sample of the same gas that
contains 2.7 g/L of the dissolved gas?
Answers
Answer:
[tex]14.8\ \text{atm}[/tex]
Explanation:
[tex]C_1[/tex] = Initial concentration = 1.46 g/L
[tex]C_2[/tex] = Final concentration = 2.7 g/L
[tex]P_1[/tex] = Initial pressure = 8 atm
[tex]P_2[/tex] = Final pressure
From Henry's law we have the relation
[tex]\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}[/tex]
The pressure of a sample of the same gas at the required concentration is [tex]14.8\ \text{atm}[/tex].

aerobic cellular respiration requires an adequate supply of
Answers
Answer:
oxygen ?
Explanation:
not sure but I think so
Aerobic cellular respiration requires an adequate supply of oxygen. In the presence of oxygen, the cell completely oxidised the glucose molecule to form ATP.
What is cellular respiration?In cellular respiration, the cell takes glucose and breaks it down to form energy. Cellular respiration is of two types: aerobic respiration and anaerobic respiration.
In aerobic respiration, the cell requires oxygen. Due to the presence of oxygen, the complete oxidation of glucose takes place. Glucose is converted into pyruvic acid and then enters the Krebs cycle and the electron transport chain to make ATP.
In the aerobic cellular respiration process, the maximum amount of ATP is derived. In anaerobic respiration, the cell performs respiration without the presence of oxygen. An example is glycolysis.
In this glycolysis process, the complete oxidation of glucose does not take place. In the absence of oxygen from pyruvate, lactic acid and ethanol are produced. This is called fermentation.
Hence, for aerobic cellular respiration, oxygen is required.

La leche se considera un alimento basico por su elevado contenido de nutrientes su densidad es de 1,4g/ml. Si se hace una compra de 7 bolsas de leche cada una con un volumen de 900m cual es la masa total de la leche expresada en kilogramos?
Answers
Answer:
8.82 kg es la masa total de leche
Explanation:
Consideraremos que el volumen de cada bolsa de leche es de 900 mL.
Sabiendo que tenemos en total 7 bolsas, el volumen final en litros que tenemos disponible es de:
900 mL . 7 = 6300 mL
Utilizando la densidad podemos calcular la masa de leche que tenemos en el total de las 7 bolsas
Densidad = masa / volumen
Densidad . volumen = masa → 1.4 g/mL . 6300 mL = 8820 g
Convertimos la masa de gramos a kg
8820 g . 1 kg /1000g = 8.82 kg

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?
Answers
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4

Answers
Answer:
Option D.
Explanation:
Percentage yield = Actual yield / Theoretical yield * 100%
Actual yield = 11.0 grams
Theoretical yield = 12.3 grams
Percentage yield = 11.0 / 12.3 * 100
Percentage yield = 89.43%

A mixture of Oxygen and Hydrogen occupies a pressure of 101.3kPa. The pressure of Hydrogen is 56kpa. Calculate the pressure of oxygen.
Answers
Answer:
45.3 KPa
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 101.3 KPa
Pressure of Hydrogen (Pₕ) = 56 KPa
Pressure of Oxygen (Pₒ) =?
The pressure of oxygen in the mixture can be obtained as follow:
Pₜ = Pₕ + Pₒ
101.3 = 56 + Pₒ
Collect like terms
101.3 – 56 = Pₒ
Pₒ = 45.3 KPa
Thus, the pressure of oxygen in the mixture is 45.3 KPa
