Heather is doing an acid-base reaction. She has 25.00 mL of hydrochloric acid of unknown concentration in a flask. She wants to add a basic solution to the acid drop by drop, until all the acid has reacted. Which tool would be best for adding the basic solution dropwise and for most precisely measuring the volume of solution added?

a graduated cylinder
an eye dropper
a beaker
a buret

Answers

Answer: a buret

A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.

A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.

A burette would be the best tool for the required use.

If we assume that 60 % of the kinetic energy delivered by a 1.80-kg hammer with a speed of 7.80 m/s is transformed into heat that flows into the nail and does not flow out, what is the temperature increase of an 8.00-g aluminum nail after it is struck ten times?

Answers

Answer:

45.6°C

Explanation:

Kinetic energy = $(1)/(2)mv^2$

Use m= 1.80kg and v=7.80m/s (mass and speed of hammer).

K = 0,5*1.80kg*(7.80m/s)^2 = K=54.8J

Heat is 60% of Kinetic energy. Q = 0.6*54.8J = 32.9J

As it is stuck 10 times the total heat is 10*32.9J = Total Heat = 329J

Use the equation $Q = mC_v \Delta T$ to find change of temperature:

$\Delta T = (Q)/(mC_v)$

Q = 329J; m = 8.00g of aluminium; C_v = 0.900J/g°C (For aluminium)

$\Delta T = (329J)/(8.00g*0.900J/g°C)$

Calculating gives Change of Temperature = 45.6°C

Why do deer depend on plants to survive

Answers

Deer depend on plants to survive because they are herbivores. Herbivores are animals that only eats plants and fruits in order to survive. Deer's meal includes grass and evergreen plants. If grass is unavailable, they eat whatever food like fallen leaves, twigs, bushes and other woody plants.

The ________________ theory of matter states that all particles of matter are in constant motion.

Answers

The kineticmolecular theory of matter states that all particles of matter are in constantbattering motion. It is mostly applied to gaseous particles. This is becausethey have room for movement in that their distance between each particle isgreat. That is why gases has greater volume compared to liquids and solids. Anexample of this is 1 kg of liquid water. It is placed inside the balloon. When heated,you observed that the balloon expands. This is because the particles of liquidwater do not want to be so close with each other. That is why it expands.

The kinetic molecular theory of matter states that all particles of matter are in constant motion. Kinetic energy is energy in motion, while potential energy is energy at rest.

How can three resistors of resistances 2 ohm 3 ohm and 6 ohm be connected to give a total resistance

Answers

Explanation:

Three resistors of resistances 2ohm,3ohm, and 6ohm respectively.

Let R1=2Ω

⇒R2=3Ω

⇒R2=6Ω

● A total resistance of 4Ω from three resistors of given resistances. Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance.

●When R 2 and R 3 are connected in parallel with

R1 in series we get

⇒1/R=1/R2+1/R3

⇒1/R=1/3+1/6

⇒1/R=1/2

⇒R=2Ω

●Hence, the total resistance of the circuit is 4Ω.

Think about what subsequently happens to the ketchup, which is initially at rest, and use newton's first law to explain why this technique is so successful.

Answers

Newton's first law of ketchup is if the bottle of ketchup is smacked upward, the contents (the ketchup) will tend to remain in place, and it will be closer to the opening in the bottle.

Further explanation

If we are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle a upward smack which force the bottle rapidly upward.

Newton first law said that every object tries to continue in its state of rest or uniform motion unless an external force acted upon it (In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force). Newton first law describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

Inertia explained by Sir Isaac Newton in his first law of motion (Newton law of motion). The law states that an object at rest stays at rest and an object continues its state of motion until an external force acts on it. The examples are one's body movement to the side when a car makes a sharp turn

The ketchup inside the bottle is take out by shaking the bottle up and down. This process of bringing out the ketchup from the bottle make use of Newton’s Law of Inertia or the Newton’s first law.

Further Explanation:

The Newton’s first law of motion or the Newton’s law of Inertia states that a body continues to be in its state of rest or motion until and unless an external force is applied on the body that forces the body to change its state.

This law states that there needs to be a force in order to change the state of a body whether it is in motion or it is at rest.

The ketchup inside the bottle always settles down towards the bottom of the bottle. Now when it is required to take out the ketchup from the bottle, we hold the bottle upside down and shake it to bring the ketchup out of the bottle.

As the bottle is turned and shaken, the ketchup bottle suddenly comes into state of motion whereas the ketchup inside the bottle still remains in its state of rest. As the bottle goes up, the ketchup slides down to the neck of the bottle as it wants to remain in its initial position.

In this manner, when the bottle is shaken several times, the ketchup comes out of the bottle slowly. This process of taking out the ketchup from the bottle is due to the Newton’s law of Inertia.

The Newton’s first law or Law of Inertia has its several other applications in day to day life.

• The passenger tend to fall forward in a moving bus when the driver slams the brake suddenly. It happens because due to brakes, the bus comes to rest suddenly but the passenger’s body still remains in its state of motion and therefore, it tends to fall forward.

• The dust particles come out from a mattress when it is beaten up by a stick. The beating up the mattress sets up the mattress into motion but the dust particles remain in their state of rest and therefore, they fall out of the mattress.

Thus, the technique of bringing out the ketchup from the bottle by shaking it is an application of the Newton’s first law or the Newton’s Law of Inertia.
