Answer: pH = 2.68

Explanation: pH = - log[H3O^+] .

 HCl reacts with water : HCl + H2O ->  Cl^- + H3O^+

So [H3O^+] = c(HCl) = 0.0021 M

pH = - log(0.0021) = 2.68

Answer:

A

Explanation:

A scientist is a person who conducts scientific research to advance knowledge in an area of interest.

In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. It was not until the 19th century that the term scientist came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833.

Answer:  The coefficient we should change first is for [tex]NO_{3}[/tex].

Explanation:

The given reaction equation is as follows.

[tex]Al + Ni(NO_{3})_{2} \rightarrow Al(NO_{3})_{3} + Ni[/tex]

Here, number of atoms present on reactant side are as follows.

Number of atoms present on the product side are as follows.

To balance this equation, multiply Al by 2 and [tex]NO_{3}[/tex] by 3 on reactant side. Also, multiply [tex]Al(NO_{3})_{3}[/tex] by 2 and Ni by 3 on the product side.

Hence, the equation can be rewritten as follows.

[tex]2Al + 3Ni(NO_{3})_{2} \rightarrow 2Al(NO_{3})_{3} + 3Ni[/tex]

Now, number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

Since, the atoms on both reactant and product side are same. Hence, it is now a balanced chemical equation.

Thus, we can conclude that the coefficient we should change first is for [tex]NO_{3}[/tex].

Answer:

C. 2Fe + 3Cl2 + 2FeCl3

Explanation:

Hello there!

In this case, according to the given chemical reaction:

Fe + Cl2 → FeCl3

It turns out possible to balance it via cross-multiplying the chlorine atoms as they do not result from a whole number multiplication; it means we get:

Fe + 3Cl2 → 2FeCl3

And we just balance Fe by placing a 2 on Fe:

2Fe + 3Cl2 → 2FeCl3

Thus, the answer is C. 2Fe + 3Cl2 + 2FeCl3

Answer:

K2S(aq) + BaCl2(aq) = 2KCl(aq) + BaS(s)

In the image attached, it is explained how the solution is balanced.

The number of atoms of any element in the given chemical formula is the number that is written on the foot of the symbol of that element. The   balanced equation is

K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side.

The unbalanced equation is

K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]KCl(aq) + BaS(s)

The number of atoms of K on reactant side is 2 while on product side it is 1, so to balance K we need to multiply KCl by 2

K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]2KCl(aq) + BaS(s)

The atoms of sulfur on reactant and product side is 1, so it is balanced.

The atoms of Ba on reactant and product side is 1, so it is balanced.

The atoms of Cl on reactant and product side is 2, so it is balanced.

Therefore the balanced equation is

K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)

Answer:

1.0 mole

Explanation:

From the question given above, the following data were obtained:

Volume (V) = 5 L

Temperature (T) = 205 K

Pressure (P) = 340 KPa

Gas constant (R) = 8.31 KPa.L/Kmol

Number of mole (n) =?

Using the ideal gas equation, the number of mole of the gas in the container can be obtained as follow:

PV = nRT

340 × 5 = n × 8.31 × 205

1700 = n × 1703.55

Divide both side by 1703.55

n = 1700 / 1703.55

n = 1.0 mole

Thus, the number of mole of the gas in the container is 1.0 mole

Answer:

Antarctic Peninsula, is one of the most important fossil sites on Earth.

hope this helps you ☺️☺️

Fossils that would be expected to be found in Antarctica from more recent times, after it had moved much closer to the South Pole is Antartica peninsula.

Fossils are the preserved remains, impression, or trace of any once-living thing from many years ago. Examples of the fossils include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants.

There are four different types of fossils-

Mold fossils

Cast fossils

Trace fossils or Ichnofossils

True form fossils

Imprints, tracks, and trails can also become fossilized and are called Trace fossils. Dinosaur footprints or worm burrows are the examples.

Living things when get decomposed from the so many years ago and become dirt and rocks are fossils.

Therefore, Fossils that would be expected to be found in Antarctica from more recent times, after it had moved much closer to the South Pole is Antartica peninsula.

Answer:

Precipitation reactions are ones in which at least one of the reactants is in the aqueous phase (i.e., dissolved in water), and a solid forms on the product side which was not present on the reactant side. If all the reactants are solid, then a solid product forming should not be called a precipitate. To be called a precipitate, an insoluble product must form from within solution, either from a solid and solute interacting, or from an interaction strictly between solutes.

Answer:

0.244 M.

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 1 M

Volume of stock solution (V₁) = 0.305 L

Volume of diluted solution (V₂) = 1.25 L

Molarity of diluted solution (M₂) =?

The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:

M₁V₁ = M₂V₂

1 × 0.305 = M₂ × 1.25

0.305 = M₂ × 1.25

Divide both side by 1.25

M₂ = 0.305 / 1.25

M₂ = 0.244 M

Thus, the molarity of the diluted solution is 0.244 M

We are given:

Initial Temperature = 90°c

Final Temperature = 120°c

Heat applied(ΔH) = 500 Joules

Specific heat(c) = 0.9 Joules / g°C

Mass of Aluminium(m) = ?

Change in temperature:

ΔT = Final temp. - Inital Temp.

ΔT = 120 - 90

ΔT = 30°c

Calculating the mass:

We know the formula:

ΔH = mcΔT

replacing the values:

500 = m(0.9)(30)

500 = m(27)

m = 500/27

m = 18.52 grams

Specifically in the year 1993, a comet was discovered by three individuals namely: Eugene Shoemaker, Carolyn Shoemaker, and David Levy. The comet was named after the first discoverers as; Shoemaker-Levy 9.

Shoemaker-Levy 9 was reported to have already been in pieces as at the time of discovery. It was believed to have been torn apart by the gravitational force emanating from the biggest of the planets called JUPITER.

In July 1994, Shoemaker-Levy 9 came in contact with Jupiter in what seemed to be the end of the discovered comet. This collision of Shoemaker-Levy 9 with planet Jupiter was said to be the first ever solar systems collision observed.

Answer:

Mg + 2 HCl ⇒ MgCl₂ + H₂

10.1 L

Explanation:

Step 1: Write the balanced equation

Mg + 2 HCl ⇒ MgCl₂ + H₂

Step 2: Calculate the moles corresponding to 10.0 g of Mg

The molar mass of Mg is 24.31 g/mol.

10.0 g × 1 mol/24.31 g = 0.411 mol

Step 3: Calculate the moles of H₂ produced from 0.411 moles of Mg

The molar ratio of Mg to H₂ is 1:1. The moles of H₂ produced are 1/1 × 0.411 mol = 0.411 mol

Step 4: Calculate the volume occupied by 0.411 moles of H₂

0.411 moles of H₂ are at 1.00 atm and 25 °C (298 K). We can calculate the volume occupied using the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 0.411 mol × (0.0821 atm.L/mol.K) × 298 K / 1.00 atm = 10.1 L
