Answer:

An objects motion is called kinetic energy.  Which is energy that is cause by movement or motion

Explanation:

Answer:

An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity

Explanation:

an object that is not changing its velocity is said to have an acceleration of 0 m/s/s. Thus, we could provide an alternative means of defining inertia

The correct option for the following reaction is [tex]\gamma[/tex].

In the given reaction we can easily see that the reaction is already complete as a nuclear equation. There is no need for the product to balance the equation as it is not a chemical reaction where reactants and products interact to form new substances.

In this question we can see that a radioactive isotope of iodine-125 ( [tex]^{125}_{53} I[/tex] ) is decaying to produce another isotope of iodine-125 ( [tex]^{125}_{53}I[/tex] ) this process is called beta decay.

As no new element is required to balance the reaction we can say that the answer to this is [tex]\gamma[/tex] as it doesn't add up anything to the reaction.

Explanation:

As per the equation, let us calculate the mole ratio. N2+3H2→2NH3. As per the equation one mole of nitrogen  reacts with 1 mol of hydrogen.

In terms of mass. 28.01 g of nitrogen needs 3 mol of hydrogen or 6.048 g of hydrogen.

Answer:

a. more mosquitos more malaria

b. DDT worked to keep malaria numbers down by killing mosquitos

c. silent spring's great PR campaign got it banned and with the help of the EPA it was banned almost worldwide and if it was not banned manufacturing it stopped

d. it will continue to increase and 100s of millions of dead will be stacked even higher from malaria

Explanation: it is a tragedy, not sure if that is what you were given to read but that is the side that is rarely told

the birds all dying was not correct, it is not a cartcinogen, it doesn't poison the ocean

here is an interesting quote that is rather telling about how some with power make their decisions

My own doubts came when DDT was introduced for civilian use. In Guyana, within two years it had almost eliminated malaria, but at the same time the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it has greatly added to the population problem.

Answer:

5.3 mL

Explanation:

We solve this problem using Archimede's principle, which states that the volume displaced by a submerged object is equal to the volume of the object.

With that in mind we calculate the volume of water displaced by the medallion:

As the medallion displaced 5.3 mL of water when submerged, the volume of the medallion is also 5.3 mL.

Answer:

2.17 moles of gas.

Explanation:

Answer:

Explanation:

From your question you’ll have to assumethat the temperature is constant,since you do not have an initial temperature.

If thats the case thrn you can use;

P1V1=P2V2 to calculate the second volume.

P1=1200 torr

P2=760 torr

V1 = 20.4L

The volume occupied by 20.4 liters of Carbon dioxide (CO₂) at 1200 Torr when it is at Standard temperature pressure is 32.21 L.

Volume of gas can be calculated by arranging the ideal gas equation as:

P₁V₁ = P₂V₂, where

P₁ = given pressure = 1200 Torr

V₁ = given volume = 20.4 L

P₂ = standard pressure = 760 Torr

V₂ = to find?
Here, we consider the moles and temperature of gas is constant, on putting all these value on the above equation we get:

V₂ = (1200 × 20.4) / 760 = 32.21 L

Hence, 32.21 L is the required volume.

Answer:

The formula weight of the compound is

46.069 g/mol.

Explanation:

Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:

molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.
