What is different about the rotation of Uranus?

the axis is vertical
there is no axis of rotation
the axis is pointing toward the sun

Answers

Answer:

Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.

What is formed when two liquids are combined but do not mix?

Answers

Answer:immiscible

Explanation:

When two liquids combine to form a new liquid, we call the liquids “miscible.” When two liquids do not mix together and instead form layers, we call them “immiscible.” The chemical properties of the liquids will determine if they will mix or not.

The chart shows the time, initial velocity, and final velocity of three riders.


A 4-column table with 3 rows. The first row labeled rider has entries Gabriella, Franklin, Kendall. The second row labeled time with entries 10 seconds, 8.5 seconds, 6 seconds. The third column labeled initial velocity has entries 55, 50, 53.2. The fourth column labeled final velocity has entries 32, 50, 67.


Which best describes the riders' final velocities ?

Gabriella is speeding up at the same rate that Kendall is slowing down, and Franklin is not accelerating.
Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
Gabriella and Franklin are both slowing down, and Kendall is accelerating.
Gabriella is slowing down, and Kendall and Franklin are accelerating.

Answers

Answer:

Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating. Hence option B is correct.

What is acceleration?

Acceleration is defined as the speed at which an object's velocity changes over time. The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is accelerating. Acceleration can be expressed as

Acceleration = Displacement / Time

Velocity is defined as the pace at which an item changes position while moving in one direction, as seen from a certain point of view and as measured by a specific unit of time. Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path.

Thus, Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating. Hence option B is correct.

Using the balanced reaction below, drag and drop the terms into the correct location to solve the following problem:

If 1.5 moles of ethanol (C2H5OH) react, how many moles of water will be formed?

2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O

Answers

Answer:

4.5 moles of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C2H5OH + 3O2 —> 2CO2 + 3H2O

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.

Thus, 4.5 moles of H2O will be produced.

Which accurately labels the lysosome?

W
X
Y
Z

Answers

I am not sure about this but I think it’s y

Answer:

The correct answer is X.

Explanation:

Lysosomes are heterogeneous structures present in animal cells which are bound by single membranes. They are of varying shape and size and contains hydrolytic enzymes inside it.

Lysosomal membrane has H⁺ ATPase which pumps H⁺ into the membrane through ATP hydrolysis. This pumping of H⁺ makes the internal pH of lysosome acidic.

Lysosome contains many hydrolytic enzymes like protease, lipase, nuclease, therefore, lysosome protects the cell from pathogens by engulfing it and hydrolyze it by its hydrolytic enzymes.

The process by which substance comes from outside cell and broken down through lysosome is called heterophagy.

Did the chemical reaction absorb or release energy? How do you know?​

Answers

Answer:

Explanation:

All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.

The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed. Exothermic is refers to chemical reactions that release the energy.

What is chemical reaction ?

The term chemical reaction is defined as a process that leads to the chemical transformation of one set of chemical substances to another.

If heat is absorbed during the reaction,then the change in enthalpy is positive and if heat is released, then the change in enthalpy is negative.

All chemical reactions contain energy. But, not all chemical reactions release energy. In some chemical reactions, the energy is absorbed rather than released.

Thus, The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed.

The density of 25.0 g of silver is 10.5 g/cm^3. What's the density of 95.5 g of silver?​

Answers

Answer:

10.5g/cm³

Explanation:

Since the density of the silver is 10.5g/cm³, any pure sample of silver will have the same value as the density of silver.

Density is the mass per unit volume of a substance.

It is an intrinsic property of matter and does not depend on the amount of matter it contains. Every unique sample of an element or substance will have the same density no matter how big or small they are. So, despite an increase in mass for the given substance, the density will still be the same.

What is the energy of a microwave photon that has a frequency of 9.86 x 1012 Hz?

Answers

Answer:

6.533 × 10^-21J

Explanation:

The energy of the microwave photon can be calculated using:

E = hf

Where;

E = energy of photon (J)

h = Planck's constant (6.626 × 10^-34 J/s)

f = frequency (9.86 x 10^12 Hz)

Hence, E = hf

E = 6.626 × 10^-34 × 9.86 x 10^12

E = 65.33 × 10^(-34 + 12)

E = 65.33 × 10^(-22)

E = 6.533 × 10^-21J

The energy of the microwave photon is
