Answer:

Kinetic energy depends on the velocity of the object squared

Explanation:

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples. ... Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive.

This page looks at the manufacture of alcohols by the direct hydration of alkenes, concentrating mainly on the hydration of ethene to make ethanol.

The steps in the ethanol production process include milling the corn to meal, liquefying the meal by adding water and cooking, breaking down starch into sugar, using yeast to ferment the sugar to ethanol, distilling the ethanol by boiling off and condensing it by removing residual water and finally denaturing so that...

Answer:

The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

Considering the ideal gas law, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

In this case, you know:

Replacing:

2 atm× V = 4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K

Solving:

V = (4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K)÷ 2 atm

V= 68.67 L

Finally, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

To solve for number one we must follow these steps:

m = 703.55 g − 345.8 g

m = 357.75 g

Then we solve for the density-

d = 357.75 g / 225 mL

d = 1.59 g/mL

Answer for number 5) 1.59 g/mL

Density= Mass/Volume

therefor- Mass = 65.14g and Volume = 35.4mL

Density = 65.14g/35.4 mL = 1.84 g/mL

Answer for number 6) 1.84 g/mL

Question 7-

g = (0.8765 g/mL)(250.0 mL) = 219.1 g

Answer: 219.1 g

Question 8-

Density = mass/volume

Mass = 1587g

4.5cm x 5.2cm x 6cm = 140.4 cubic-cm

Volume = 140.4 cubic-cm

Mass/volume = 1587/140.4 = 11.3 g/cm^3

Answer: 11.3 g/cm^3

Question 9:

First calculate the volume of iron

49.10mL − 45.50mL = 3.60mL

Density = mass/volume;

density = 28.5g/3.60 mL= 7.92 g/mL

Answer: 7.92 g/mL

Question 10:

Volume = 2500.0g / 10.5g/cm3 = 238.095cm^3

Now we round up the answer to 238cm^3

Answer: 238cm^3

At the left side; the balanced half equation is:

[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]

At the right side, the balanced half equation is:

[tex]\mathbf{4OH^-_{(aq)} \to O_{2(g)} + 2H_2O_{(l)} + 4e^-}[/tex]

The objective of this question is to determine the balanced half-reaction for the electrodes on the left and the right side.

A half-reaction is an oxidation-reduction reaction part of a redox reaction where we make sure both half-reactions are balanced by multiplication of the reactions with appropriate numbers in order to have an equal number of electrons.

According to the given information:

The overall cell reaction can be expressed as:

[tex]\mathbf{H_2O_{(l)} \to H_{2(g)} + \dfrac{1}{2}O_{2(g)}}[/tex]

At the left side; the balanced half equation can be expressed as:

[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]

At the right side, the balanced half equation can be expressed as:

[tex]\mathbf{4OH^-_{(aq)} \to O_{2(g)} + 2H_2O_{(l)} + 4e^-}[/tex]
