Is apple juice a homogeneous mixture or a heterogeneous mixture

2 answers:

If you mean the industrialized apple juice then yes. Even though there are several different compounds and some of them aren't actually dissolved in the liquid, since you can't actually distinguish between them using only your eyes and they do no separate naturally it is actually a homogeneous mixture.

<u>Answer:</u> Apple juice is a homogeneous mixture.

<u>Explanation:</u>

There are two types of mixtures:

Homogeneous mixtures are defined as the mixtures that appears uniformly throughout the solution and the particle size or shapes are not different.
Heterogeneous mixtures are defined as the mixtures which appears non-uniformly throughout the solution and the particle size or shapes are also different.

Apple juice is a homogeneous mixture because the juice appears uniform throughout and no phases between the particles is seen.

Hence, apple juice is a homogeneous mixture.

Learning Task No. 2: Study the diagram above. Answer the guide questions.

1. "Fn" stands for "Normal Force," "Fg" for "Gravity Force," "Ff" for "Force Friction," and "A" for "Applied Force." 2. As a result of the friction, which causes the ball to stop. 3. The reason the ball rolls is due to the force that is imparted to it.

The definition of force is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. A force that opposes this motion of the hands is activated when they brush against one another. Frictional force is the force resisting motion applied in the direction perpendicular to the direction of motion of the hands.

Solid aluminum (AI) and oxygen (O_2) gas react to form solid aluminum oxide (Al_2O_3). Suppose you have 7.0 mol of Al and 9.0 mo

Nimfa-mama [501]

Answer:

There will be formed 3.5 moles of Al2O3 ( 356.9 grams)

Explanation:

Step 1: Data given

Numbers of Al = 7.0 mol

Numbers of mol O2 = O2

Molar mass of Al = 26.98 g/mol

Molar mass of O2 = 32 g/mol

Step 2: The balanced equation

4Al(s) + 3O2(g) → 2Al2O3(s)

Step 3: Calculate limiting reactant

For 4 moles Al we need 3 moles O2 to produce 2 moles Al2O3

Al is the limiting reactant, it will be consumed completely (7 moles).

O2 is in excess. There will react 3/4 * 7 = 5.25 moles

There will remain 9-5.25 = 3.75 moles

Step 4: Calculate moles Al2O3

For 4 moles Al we'll have 2moles Al2O3

For 7.0 moles of Al we'll have 3.5 moles of Al2O3 produced

Step 5: Calculate mass of Al2O3

Mass Al2O3 = moles Al2O3 * molar mass Al2O3

Mass Al2O3 = 3.5 moles* 101.96 g/mol

Mass Al2O3 = 356.9 grams

There will be formed 3.5 moles of Al2O3 ( 356.9 grams)

The diagram below shows an electromagnet. Using your scientific knowledge, state the device that is used to measure the potentia

weeeeeb [17]

Voltmeter is the device that is used to measure the potential difference across the battery.

<h2>What are the usage of voltmeter?</h2><h3 /><h3>Usage of Voltmeter</h3>

Voltmeter is an instrument that measures voltages of both direct and alternating electric current. On a scale of voltmeter usually graduated in volts, millivolts (0.001 volt), or kilovolts (1,000 volts).

Voltmeter is connected in parallel form. It has a high resistance so that it takes negligible current from the circuit so we can conclude that Voltmeter is the device that is used to measure the potential difference across the battery.

If heat transfers from the system (solute) to the surroundings (solvent), then AH is

balu736 [363]

Answer:

B) exothermic.

Explanation:

Hello!

In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.

In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:

B) exothermic .

Best regards!
