Answer:

0.0153 mol

Explanation:

Mass of crucible and lid: 29.307 g

Mass of crucible, lid, and silver: 30.958 g

Number of moles = Mass /Molar mass

Mass of Silver = Mass of crucible, lid, and silver  -  Mass of crucible and lid

Mass of siilver = 30.958 g - 29.307 g

Mass of silver = 1.651 g

Molar mass of silver = 107.868 g/mol

Number of moles = 1.651 g / 107.868 g/mol

Number of moles = 0.0153 mol

Answer:

C3H7NO2

Explanation:

The chemical formula of Alanine is C3H7NO2 and it belongs to almost all food category because it is present in one food of each food category such as dairy products, meat, nuts, soy, and whole grains etc. Alanine is a nonessential amino acid means that it does not directly obtained from the diet but it can be produced by the body using raw materials present in the food.

Explanation:

Answer:

The gravitational potential energy and kinetic energy of this ball should be equal (assuming that there is no energy loss due to friction.)

Explanation:

The ball loses gravitational potential energy as it rolls down the hill. At the same time, the speed of the ball increases, such that the ball gains kinetic energy.

If there is no friction on this ball (and that the ball did not deshape,) all the gravitational potential energy that this ball lost would be converted to kinetic energy.

If the gravitational field strength [tex]g[/tex] is constant throughout, the gravitational potential energy of an object in that gravitational field would be proportional to its height.

If [tex]m[/tex] denote the mass of this ball, the gravitational potential energy ([tex]\rm GPE[/tex]) of this ball at height [tex]h[/tex] would be [tex]{\rm GPE} = (m \cdot g) \cdot h[/tex], which is proportional to [tex]h\![/tex].

The value of [tex]g[/tex] near the surface of the earth is indeed approximately constant (typically [tex]g \approx 9.8\; \rm m \cdot s^{-2}[/tex].)

At halfway between the top and bottom of this hill, the height of this ball would be [tex](1/2)[/tex] of its initial value (the value when the ball was at the top of the hill.) Because the [tex]\rm GPE[/tex] of this ball is proportional to its height, at halfway down the hill, the [tex]\rm GPE\![/tex] of this ball would also be [tex](1/2)\![/tex] its initial value.

However, if there was no friction on this ball (and that the ball did not deshape,) that [tex](1/2)[/tex] of the initial [tex]\rm GPE\![/tex] of this ball was not lost. Rather, these [tex](1/2)\![/tex] of the initial [tex]\rm GPE[/tex] would have been converted to the kinetic energy ([tex]\rm KE[/tex]) of this ball.

Hence, when the ball is halfway down the hill:

[tex]\displaystyle \text{GPE halfway down the hill} = \frac{1}{2}\, \text{Initial GPE}[/tex].

[tex]\begin{aligned}& \text{KE halfway down the hill}\\ &= \text{Initial GPE} - \text{GPE halfway down the hill}\\ &= \text{Initial GPE} - \frac{1}{2}\, \text{initial GPE}\\ &= \frac{1}{2}\, \text{Initial GPE}\end{aligned}[/tex].

Therefore:

[tex]\begin{aligned}& \text{GPE halfway down the hill} \\ &= \frac{1}{2}\, \text{Initial GPE} \\ &= \text{KE halfway down the hill}\end{aligned}[/tex].

In other words, under these assumptions, when this ball is halfway down the hill, the gravitational potential energy and the kinetic energy of this ball would be equal.

Answer:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Explanation:

That is what I think on the subject

A law is more specific, such as this particular description of matter, whereas a theory can be more general and often includes more of a why. Atomic Theory explains why the law of conservation of matter exists; in chemical reactions, atoms simply rearrange and have the same mass before and after.

A theory is a well-thought-out elaboration for natural-world anecdotes that has been built using the methodological approach and incorporates many facts and hypotheses.

A scientific law, in overall, is a description of an observed phenomenon. It does not explain why or what causes the phenomenon.

A scientific theory is an explanation for a concept. It is a common misconception that with enough research, theories can become laws.

A law is more precise, such as this detailed definition of matter, whereas a theory is more general and frequently includes more of a why.

Atomic Theory explains why the law of conservation of matter exists; atoms simply rearrange and have the same mass before and after chemical reactions.

Thus, that's why, the law of conservation of mass law and not a theory.

These equipments include:

--> Eyewash station: This is an equipment used in the laboratory during emergency to rinse chemical from the eye. Therefore option D is correct.

--> Absorbent material: They are used to contain small spills in the laboratory. Therefore option G is correct.

--> Fire extinguisher: This equipment is used to put out small fires. Therefore F is correct.

--> Safety Shower: This is used to rinse away chemical from clothes and on skin during emergency. Therefore option E is correct.

--> Biohazard container: This container is used to safely dispose bacteria culture, blood and other living tissues. Therefore option J is correct.

--> Broken glass container: This is used to dispose cracked, chipped or broken bottle in the laboratory. Therefore option I is correct.

--> Safety goggles: This helps to protect the eye from chemical and broken glasses. Therefore option C is correct.

--> Lab apron: This is worn by the laboratory personnel to help protect the skin from chemical and biohazards. Therefore option H is correct.

--> Asbestos gloves: these are heat resistant gloves used to protect the hands from heat. Therefore option A is correct.
