Explanation:

what is the mass of [tex]Fe^{2+}[/tex] in 5 tablets of iron if the number of moles of [tex]Fe^{2+}[/tex] is 4.2225 x [tex]10^{-4}[/tex] mol.
[ Ar = Fe, 56 ]

Answers

Answer:

Approximately [tex]0.11823\; \rm g[/tex] in total for the five tablets.

(Approximately [tex]2.3646 \times 10^{-2}\; \rm g[/tex] per tablet.)

Explanation:

The relative atomic mass of an element is the ratio between:

the mass of one atom of this element, and the mass of one-twelfth of a carbon-[tex]12[/tex] atom.

The definition of moles ensures that the relative atomic mass of an element is approximately numerically equal to the mass (measured in grams) of one mole of the atoms of this element.

The question states that the relative atomic mass [tex]A_{\rm r}[/tex] of iron is [tex]56[/tex]. In other words, the mass of one mole of iron [tex]\rm Fe[/tex] atoms would be approximately [tex]56\; \rm g[/tex].

The question is asking for the mass of some amount of [tex]\rm Fe^{2+}[/tex] ions. Each [tex]\rm Fe^{2+}\![/tex] ion contains two fewer electrons than a neutral [tex]\rm Fe[/tex] atom. Hence, [tex]4.2225 \times 10^{4}\; \rm mol[/tex] of [tex]\rm Fe^{2+} \![/tex] ions might be lighter than the same number of [tex]\rm Fe \![/tex] atoms by a very small extent: The mass of one mole of electrons is approximately [tex]5 \times 10^{-4}\; \rm g[/tex], much smaller than the mass of the same number of [tex]\!\rm Fe[/tex] atoms (approximately [tex]56\; \rm g[/tex].)

Estimate the mass of these [tex]4.2225 \times 10^{4}\; \rm mol[/tex] of [tex]\rm Fe^{2+}[/tex] ions using the mass of the same number of [tex]\rm Fe[/tex] atoms:

[tex]\begin{aligned}&m({\rm Fe^{2+}}) \\ &\approx m({\rm Fe}) \\ &\approx 4.2225 \times 10^{-4}\; \rm mol \\ &\quad\quad \times 56\; \rm g \cdot mol^{-1} \\ &\approx 2.3646 \times 10^{-2}\; \rm g \end{aligned}[/tex].

Five of these tablets would contain approximately [tex]5 \times 2.3646 \times 10^{-2}\; \rm g \approx 0.11823\; \rm g[/tex] of [tex]\rm Fe^{2+}[/tex] ions.

PLEASE HELP "Which of the following substances would have the lower concentration of hydrogen ions ?"

Answers

The lower the pH, the greater the concentration of hydrogen ions (this is one of the definitions of an acid: a substance that increases the hydrogen ion concentration in water). So the answer here would be the one denoting the highest pH value, since that would indicate the smallest concentration of hydrogen ions.

That would be the substance with a pH of 11.2. Thus, the second answer choice here would be correct.

B.) a phase change. I think but for sure it’s not C-

The most likely to take place when a solid is placed in a liquid at room temperature ( i.e. 20°C ) is ; ( A )  A chemical reaction

Although your question lacks the required diagram a general answer is provided within the scope of your question

When a solid at 20°C is placed inside a liquid also at 20°C  in the laboratory the emergence of gas bubbles shows that there has been a chemical change between the solid and liquid reactant ( i.e. a chemical reaction has taken place ).

Hence we can conclude that what is most likely to have taken place in this situation is a Chemical reaction.

What is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K), is heated from 25°C to 15°C?

A. 21 J
B. 0.21 J
C. 210 J
D. It is impossible to calculate without knowing the mass of the iceberg

Answers

Answer:

A. 21 J

Explanation:

Your temperature change is 10 degrees Celsius, or 10 Kelvin, it makes no difference either way.

Cp = 2.06 J/g•K

Multiply by the temperature change to just get J/g

2.06 J/g•K • 10 K = 20.6 J/g ≈ 21 J/g

21 J is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K) which is heated from 25°C to 15°C. So, the correct option is A.

What is Heat?

Heat is defined as the energy that is transferred from one body to another as a result of a difference in temperature, when two bodies at different temperatures are brought together, the energy transferred is that of the hotter body which flows towards the colder body.

In this case, according to the equation for the calculation of the heat during a heating process

[tex]Q= mC (T_f- T_i)[/tex]

It is possible to calculate mass per gram of ice by dividing both sides by removing m from the equation, we plug in the given specific heat and final and initial temperatures to get:

[tex]Q= 2.06 \frac{J}{g degree C} [-15 Degree C- (-25 Degree C][/tex]

[tex]Q= 20.6\frac{J}{g}[/tex] which is equals to 21° C

21 J is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K) which is heated from 25°C to 15°C.

Therefore, the correct option is A.

After a skydiver deploys
his parachute, his rate of
speed decreases.

Answers

Answer:

As a skydiver falls, he accelerates downwards, gaining speed with each second. The increase in speed is accompanied by an increase in air resistance (as observed in the animation below). This force of air resistance counters the force of gravity. As the skydiver falls faster and faster, the amount of air resistance increases more and more until it approaches the magnitude of the force of gravity. Once the force of air resistance is as large as the force of gravity, a balance of forces is attained and the skydiver no longer accelerates. The skydiver is said to have reached a terminal velocity.
