What is the specific heat capacity of silver metal if 110.00 g of the metal
absorbs 396 J of heat and the temperature rises 15.0°C ?

volume.

The amount of space a material occupies is its volume.

Mass is measured using a scale. Volume is the amount of space matter takes up. Volume can be measured by multiplying the length, width, and height of an object, or by using a measuring cup and seeing how the measurement of water changes in a cup. Density is the amount of matter an object has in a certain space.

Answer:

7242.1g

Explanation:

The balanced equation for this reaction is as follows:

Mg + 2HCl → MgCl2 + H2

From the above equation, it can be observed that 2 moles of HCl is needed to produce 1 mole of H2.

Using the formula below, we convert the mass of H2 to moles;

Molar mass of H2 = 2.016g/mol

mole = 200/2.016

mole = 99.21mol of H2

Since 2 moles of HCl is needed to produce 1 mole of H2.

Then 99.21 moles of H2 will be produced by 99.21 × 2 = 198.4mol of HCl

Molar mass of HCl = 1 + 35.5

= 36.5g/mol

Mole = mass/molar mass

Mass = molar mass × mole

Mass = 36.5 × 198.4

Mass = 7242.1g

Answer:

NH3(aq) and HCl(aq) are the reactants, while NH4Cl(aq) is the product.

Explanation:

The hydrogen atom from the HCl molecule joins the other three in NH3 creating a four hydrogen molecule,  NH4Cl.

B

Explanation:

Answer:

The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0.

If an object is on top of a hill or in a position raised above the ground, it must have gravitational potential energy.

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors

If an object is lifted, work is done against the force of gravity.

When work is done energy is transferred to the object and it gains gravitational potential energy.

If the object falls from that height, the same amount of work would have to be done by the force of gravity to bring it back to the Earth’s surface.

Due to the Principle of Conservation of Energy we can say that:

Gravitational potential energy at the top = kinetic energy at the bottom

Answer:

D

Explanation:

Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel. For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF6), which enables it to be enriched.

Unstable U-235 must be enriched with 5% U-238 to stabilize it.​ Hence, option D is correct.

Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei into atomic nuclei to form more energetically stable atomic nuclei.

P2 = 54.6 kPa

Explanation:

Given:

V1 = 10.0 L. V2 = 50.0 L

P1 = 273 kPa. P2 = ?

We can use Boyle's law to solve this problem.

P1V1 = P2V2

Solving for P2,

P2 = (V1/V2)P1

= (10.0 L/50.0 L)(273 kPa)

Answer:

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.

Explanation:

I did this on Savvas Realize got it right.

Genetic variation is said to be the difference in the hereditary sequence. After the industrial revolution, the frequency of the dark-colored moth increased dramatically more than the light-colored moths.

Industrial melanism was an example of the evolutionary effect that occurred in the moths where the dark-colored species were favored over the light-colored species of peppered moths.

Before the industrial population, light-colored moths were large in number which later decreased with an increase in pollution. This occurred due to an increase in the pollutants and dust deposition that altered the environment.

As the pollution increased over time the dark-colored moths became dominant and increased their population over time. This is an example of industrial melanism as the color of the body was the determining factor in survival.

Therefore, dark-colored moths were prevalent after the industrial revolution.

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new volume we have

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

First convert 745 mmHg to atm

760 mmHg = 1 atm

745 mmHg = 745/760 = 0.98 atm

Answer:

Q = 20377.5 Joules

Explanation:

Given the following data;

Mass = 75g

Initial temperature = 65°C

Final temperature = 0°C

Specific heat capacity of water = 4.18 J/g°C.

To find the quantity of heat released;

Heat capacity is given by the formula;

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Substituting into the equation, we have;
