Zinc reacts with hydrochloric acid according to the reaction equation Zn(s)+2HCl(aq)⟶ZnCl2(aq)+H2(g) How many milliliters of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s)?

Answers

Answer:

41.17

Explanation:

n Zn =  mass / m.wt

      = 8.75 /(65.4) = 0.1338 mole

n HCL = ( from the balanced equation )

     2HCL                  Zn

          2mole   → 1  mole

          x  mole     →             0.1338mole

     n HCL = .268 mole

M= mole/liter

6.50= 0.268/x

so u have0.04117  liter = 41.17 ml

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 41.17 ml of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s).

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

number of moles of zinc=  mass / molecular mass

                                       = 8.75 /(65.4) = 0.1338 mole

number of moles of HCl ( from the balanced equation )

2 moles of HCl reacts with one mole of Zn

number of moles of HCl = 2×0.1338 =0.268 mole

Molarity = number of mole of HCl/volume occupied by solution

6.50= 0.268/volume

Volume of HCl = 41.17 ml

Therefore, 41.17 ml of 6.50 M HCl(aq) are required to react with 8.75 g Zn(s).

Question 26 (1 point)
Use the periodic table to determine which statement below is true of the element Bromine (Br).

•Bromine will lose 7 valence electrons to become a negative ion.
•Bromine will lose 7 valence electrons to become a positive ion.
•Bromine will gain 1 valence electron to become a negative ion.
•Bromine will gain 1 valence electron to become a positive ion.

Answers

Answer:

The correct option is;

Bromine will gain 1 valence electron to become a negative ion

Explanation:

Bromine can be found in period 4 in group 17 of the periodic table and is an halogen

The electron configuration of bromine can be presented as follows;

Electronic configuration 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁵

Therefore, an atom of bromine has 2 + 5 or 7 electrons in its outermost shell, which makes it have one less electron to complete a full octet structure and therefore, bromine has a strong affinity for electron to complete its octet structure and it is thus a strong oxidizing agent.

When bromine enters into a chemical reaction and gains the one valence electron it becomes a negatively charged ion.

Terry bought a gold necklace at a pawnshop and was wondering if it was “real” gold. She decided to perform a density test. She placed the necklace in a graduated cylinder of water that had 47.00 mL of water and the water rose to 48.35 mL. She then weighed the necklace and found it to have a mass of 22.89 g. What is the density of Terry’s necklace?

Answers

Answer:

d = 16.96 g/mL

Explanation:

Given that,

Initial water level in graduated cylinder is 47 mL and final water level is 48.35 mL.

The weight of the neclace is 22.89 g.\

We need to find the volume of the necklace. We know that, density equals mass per unit volume. So,

[tex]d=\dfrac{m}{V_f-V_i}\\\\d=\dfrac{22.89\ g}{(48.35-47)\ mL}\\\\d=16.96\ g/mL[/tex]'

Hence, the density of Terry’s necklace is 16.96 g/mL.

Please help​

Answers

Answer:

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %

Explanation:

The mass percentage of a solution is a measure of concentration that indicates the number of grams of solute that there are per 100 grams of solution.

The percent by mass is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100 to give a percentage.

[tex]percentage by mass=\frac{solute mass}{solution mass} *100[/tex]

In this case:

solute mass: 30 gsolution mass: 650 g

Replacing in the definition of percent by mass:

[tex]percentage by mass=\frac{30 g}{650 g} *100[/tex]

Solving:

percent by mass= 4.61 %

The ground-state electron configuration for an element contains an unpaired 3s electron.

Answers

Answer:

Na

Sodium is located in the third row of the periodic table, where the 3s3s3, s orbital is being filled. Because sodium is the first of the two 3s3s3, s elements, its ground-state electron configuration contains a single, unpaired 3s3s3, s electron.

Explanation:

its late but ik someone can use it

The ground-state electron configuration for an element contains an unpaired 3s electron is Sodium, Na.

The ground state electron configuration of an element shows a series of how its electrons are arranged in thier orbitals at their  lowest energy state.

The element which contained an unpaired 3s electron is the Alkali metal, Sodium.

Sodium, Na has atomic number of 11 and at ground state and will therefore be written as  1s²2s²2p⁶3s¹   We can also write the condensed form since the core electrons is the same with Ne,  a noble gas which is [Ne]3s1.

The s orbital should contain at most 2 electrons , since for sodium, it has 1 electron in the 3s orbital, we say it is unpaired.

What is the ionic charge?

Ions are two or more charged particles that make up ionic compounds. Electrostatic attraction keeps the ions together (in the solid phase) despite their opposing charges. Cations are positively charged ions, whereas anions are negatively charged ions. Many factors make ionic molecules significant.

They act as electrolytes for batteries and conduct electricity when dissolved in water. They could form a strong bond with other charged particles, such as those found in environmental samples or the human body. They find use in fireworks, flares, and lights because they are frequently multicolored when burned. The list is endless!

Studying the nomenclature used to give ionic compounds distinctive names is a good method to become familiar with and exposed to them. You will learn how to properly explain the identification of substances in language by converting from a chemical formula to a name—a highly essential problem as the diversity and complexity of known compounds keeps growing!

Therefore, the charge on chromium after losing 4 electrons is +2.

Explanation:

half of 150 is 75 and half of that is 32.5. Add that to 75 and you'll get your answer

112.5 g of iron is present in the alloy.

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

Percentage of iron (Fe) = 75%

Percentage of other elements = 25%

Mass of the alloy = 150 g

Mass of iron (Fe) =?

The mass of the iron present in the alloy can be obtained as follow:

[tex]Percentage = \frac{mass of element }{total mass }\\\\[/tex]

75% = [tex]\frac{mass of Fe}{150}[/tex]

[tex]0.75 = \frac{mass of Fe}{150}\\\\[/tex]
