Answer: mass of chlorine reacted is 3.18 g

Explanation:

2 K + Cl2 = 2KCl

no. of moles of K = mass / molar mass

= 3.50 / 39

= 0.0897

no. of moles of KCl = mass / molar mass

= 6.67 / 74.5

= 0.0895  

no. of moles of Cl2 required = number of moles of KCl / 2

= 0.0895 / 2

= 0.0448 moles  

mass of Cl2 required = no. of moles of Cl2 required x molar mass

= 0.0448 x 71

= 3.1808 g ≈ 3.18 g

Therefore mass of chlorine reacted is 3.18 g

Answer:

Smaller than the object

Real

Upside down

Explanation:

The image formed by a convex lens will always be real and smaller. The image formed is smaller than the object, real ,upside down and right side up. Hence, options 1,2,3 and 5 are correct.

Convex lens is a type of lens, in which one at least one side is curved outside. These lenses have the ability to focus an outside light beam to a spot on the opposite side by converging it.

The focal length of the convex lens is the distance from the lens's center to this point, which is known as the focus. On the other hand, a plano-convex lens has one surface that is flat and the other that is convex.

Convex lenses cause light from an item to bend, creating an upright, smaller, and inverted picture of the original object. As a result, the candle in this instance will be smaller, upside down, and actual.

Answer: Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring. They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

Explanation:

The coefficients used to balance the chemical equation given in the question are 2, 4, 1 (Option A)

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

Ag₂O —> Ag + O₂

There are 2 atoms of O on the right side 1 on the left. It can be balance by writing 2 before Ag₂O as shown below

2Ag₂O —> Ag + O₂

There are 4 atoms of Ag on the left side and 1 atom on the right side. It can be balance by writing 4 before Ag as shown below

2Ag₂O —> 4Ag + O₂

Now, the equation is balanced.

Thus, the coefficients are: 2, 4, 1

Answer:

See explanation

Explanation:

The substance under analysis must be a polar organic substance of high molecular mass. We must remember that as the magnitude of dispersion forces increases with increase in molecular mass, the melting point increases accordingly. Also polar organic substances have very high melting points due to the presence of polar bonds in the molecule..

Hence the intramolecular forces in the substance are covalent bonds while the intermolecular forces are both dispersion forces and dipole forces.

The substance may likely be 1,2,3,4,6,7,8-Heptachlorodibenzo-p-Dioxin which a white powder and melts at 264 °C.

Answer:

ATP

Explanation:

it is made by breaking glucose down

Answer:

Once the last phosphate group is removed from the ATP molecule by hydrolysis, it will form ADP plus inorganic phosphate. ADP is a lower energy molecule. The release of energy during hydrolysis of ATP can be harnessed by the cell to do work. Living things continuously use ATP but it is renewable and can be recycled.

Answer:

D) Fe³⁺, O²⁻; Fe₂O₃

Explanation:

Option D shows correctly an ion pair and the correct formula for the ionic compound the two ions form.

Ion pairs of iron and oxygen react to form iron (III) oxide. The iron (III) oxide is one of the oxides of iron. The compound is usually attacked by acids and it is often called rust. It is used in the feedstock of the steel and iron industries. This means that the compound is used in the production of iron, steel, and many alloys.

Below are some equations:

4 Fe + 3 O₂→ 2 Fe₂O₃

Fe⁰ + 3O₂⁰ →  Fe³⁺O₃²⁻

Answer:

Explanation:

Concentration of Cu⁺² = 9.25 x 10³ M

Concentration of Mn⁺² = 1.4 x 10² M

solubility product of copper carbonate = 7.08 x 10⁻⁹

solubility product of manganese  carbonate = 2.24 x 10⁻¹¹

solubility product of later is less so carbonate of manganese will come out first .

B )

[ Mn⁺² ] [ CO₃⁻² ] = 2.24 x 10⁻¹¹

1.4 x 10²  [ CO₃⁻² ] = 2.24 x 10⁻¹¹

[ CO₃⁻² ] = 1.6 x 10⁻¹³ .

the concentration of carbonate ion when this precipitation first begins

= 1.6 x 10⁻¹³ M .

Answer:

a. 4.3 mL

Explanation:

Step 1: Write the balanced neutralization reaction

HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

Step 2: Calculate the reacting moles of NaOH

11.9 mL of 0.151 M NaOH react.

0.0119 L × 0.151 mol/L = 0.00180 mol

Step 3: Calculate the reacting moles of HCl

The molar ratio of HCl to NaOH is 1:1. The reacting moles of HCl are 1/1 × 0.00180 mol = 0.00180 mol.

Step 4: Calculate the volume of 0.417 M HCl that contains 0.00180 moles of HCl

0.00180 mol × (1000 mL/0.417 mol) = 4.3 mL

According to the question,

Mass,

Volume,

As we know the relation,

→ [tex]M_1V_1 = M_2 V_2[/tex]

or,

→      [tex]V_1 = \frac{M_2 V_2}{M_1}[/tex]

By substituting the values, we get

            [tex]= \frac{11.9\times 0.151}{0.417}[/tex]

            [tex]= \frac{1.7969}{0.417}[/tex]

Answer:

a. precipitation

Explanation:

In the reaction:

Ni²⁺(aq) + 2NaOH(aq)→ Ni(OH)₂(s) + 2 Na⁺

Nickel is precipitated as Ni(OH)₂ producing Na⁺ ions.

In a precipitation two soluble ions react with each other to produce an insoluble salt.

In our problem, Ni²⁺ is reacting with OH⁻ to produce Ni(OH)₂, an insoluble salt

The reaction is a precipitation

In an acid-base reaction, an acid reacts with a base to produce water and a salt. In this problem is a base reacting (NaOH) but there are no acids in the reaction.

And in a redox reaction an ion is been oxidized whereas the other is been reduced (Loosing electrons and gaining electrons).

As you can see, Ni²⁺ still with oxidation number of 2+ in Ni(OH)₂ and Na⁺ is always +1-. Thus, this is not a redox reaction.
