Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
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 mixture of Oxygen and Hydrogen occupies a pressure of 101.3kPa. The pressure of Hydrogen is 56kpa. Calculate the pressure of oxygen.
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

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?
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?
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

Kw is 1.0 X 10^-14. What is (Delta Gº) for the process?
Answer:
ΔG° = 80 Kj/mole
Explanation:
ΔG° = -R·T·ln(Kw)
R = 0.008314 Kj/mol·K
T = 25°C = 298K
Kw = 1 x 10⁻¹⁴
ΔG° = -R·T·ln(Kw) -(0.08314Kj/mol·K)(298K)ln(1 x 10⁻¹⁴)
= -(0.008314)(298)(-32.2)Kj/mole
= 79.78Kj/mole ≈ 80Kj/mole (1 sig.-fig.)
The change in free energy for the autoionization of water at 25°C is -79.9 KJ
Using the formula;
ΔG = -RTlnK
ΔG = change in free energy = ?
R = gas constant = 8.314 J/K/mol
T = temperature = 298 K
K = equilibrium constant = 1.0 X 10^-14
Substituting into the given formula as;
ΔG = - (8.314 J/K/mol × 298 K × ln(1.0 X 10^-14))
ΔG = -7.99 × 10^4 J/mol or -79.9 KJ/mol

A. dissolved.
B. bonded.
C. divided.
D. mixed.
Answer:
B bonded
Explanation:
Two molecules of hydrogen gas (two hydrogens bonded together) are combined with one molecule of oxygen gas (two oxygen atoms bonded together) in order to form two molecules of water (two hydrogen atoms bonded to one oxygen atom). What are covalent bonds? Covalent bonds occur when two or more atoms share electrons.
In order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.
What are covalent bonds?Covalent bonds between two or more atoms occur when they share electrons. with each other.
Two molecules of hydrogen gas are combined with one molecule of oxygen gas which forms two molecules of water. Hydrogen take one electron and oxygen can donate two electrons. One oxygen shares two electron with two hydrogen with one electron gaining capacity.
Thus, in order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.
