HELP PLEASE!! ASAP What Would The Mass Be In Kg?

Answers

Answer 1

Answer:

i guess answer is 0.0600

Explanation:

Here,

Density=0.791g/cm^3

Volume=75.89ml

So,

Mass=Density*Volume

=0.791g/cm^3×75.89ml

=60.02g/cm^3.ml

Expressing them in kg

60.02/1000

=0.0600 kg

What are the forces on the wooden block when it is resting on a bench

Answers

Answer:

As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases

Explanation:

Since the static frictional force between the block and the plane is given by F = μN where

μ = coefficient of static friction and

N = normal force on plane = component of weight of block perpendicular to the plane = Wcosθ where

W = weight of block and

θ = angle of inclined plane

Now, F = μN

F = μWcosθ

Since μ and W are constant, we see that

F ∝ cosθ and cosθ ∝ θ

So, F ∝ θ

Since the static frictional force is directly proportional to the angle the plane makes with the horizontal, when the angle the plane makes with the horizontal is increased, the static friction between the block and the plane increases.

So, As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases

A)Gas
B)Liquid
C)Plasma
D)Solid

Answers

C)Plasma

.............this was for 20 characters to submit the answer-dont mind this

Matter exists in three different physical states, namely solid, liquid and gaseous state. The plasma is also an another state of matter. The correct option is C.

What is plasma?

The plasma is defined as the fourth state of matter. It is a hot ionized gas which consists of approximately equal numbers of positively charged ions and negatively charged electrons. It is not same as the neutral gas.

Since plasma contains electrically charged particles, they are strongly influenced by the magnetic and electric fields while the neutral gases are not. Like gases plasmas have no fixed volume or shape.

The density of plasma is also found to be less than solids or liquids. The plasma is known as a charged gas with strong electrostatic interactions. It is the plasma which make up the sun and stars and it is the most common state of matter in the universe as a whole.

Thus the correct option is C.

How would I do this? A beaker contains 50.0 mL of 0.25 M aluminum nitrate solution. What is the minimum volume of 0.2 M sodium sulfide solution that must be added in order to precipitate out all of the aluminum ions from the solution?

Answers

The minimum volume of 0.2M sodium sulfide that will precipitate out aluminum from 50.0 mL, 0.25 M aluminum nitrate would be 0.094 L or 94 mL

Stoichiometric calculation

From the equation of the reaction:

[tex]2Al(NO_3)_3 + 3Na_2S ---> Al_2S_3 + 6NaNO_3[/tex]

Mole ratio of Na2S and Al(NO3)3 = 3:2

Mole of 50.0 mL, 0.25 M Al(NO3)3 = 50/1000 x 0.25

                                                         = 0.0125 mole

Equivalent mole of Na2S = 3/2 x 0.0125

                                         = 0.0188 mole

Volume of 0.2M, 0.0188 mole Na2S = 0.0188/0.2

                                                          = 0.094 L or 94 mL

What are these bases in DNA?

The AGCT bases in DNA are the nucleotides that comprise it. These nucleotides include

Adenine Cytosine GuanineThymine

By always bonding adenines with thymine and Guanine with cytosines, the DNA strand maintains a constant diameter.

B. 180 kJ/mol, endothernic

C. -180 kJ/mol exothermic

D. -1340 kJ/mol exothermic ​

Answers

The heat of reaction is 180 kJ/mol hence the reaction is endothermic.

What is bond energy?

Bond energy is the energy that is required to form a bond and must be supplied in order to break the bond. In the question, we are told that the energy of the reactants is 860 kJ/mol and the bond energy of the products is 680 kJ/mol.

Heat of reaction = Bond energy of reactants - Bond energy of products

= 860 kJ/mol - 680 kJ/mol = 180 kJ/mol hence the reaction is endothermic.

For example, ceramic is a better conductor than Styrofoam. A ceramic mug filled with hot water feels warmer in your hand than a Styrofoam cup filled with hot water. However, ceramic is a worse conductor than metal. A metal mug filled with hot water would feel even hotter than the ceramic mug.
