Explanation:

When a substance or solution has pH equal to 7 then it is known as a neutral solution. And a solution with pH more than 7 is basic in nature.  

Antacid is a base that has chemical formula Mg(OH)_{2} and it is also known as magnesium hydroxide.

Hence, an antacid has pH greater than 7 (making it basic) so that it can neutralize the acid.

Therefore, when excess of acid is formed in the stomach then there occurs more hydrogen ions. Due to which pain is felt in the stomach and in this situation when an antacid is consumed then it releases hydroxide ions as it is a base due to which acid gets neutralized and we feel relieved.

Hence, we can conclude that the pH of an antacid solution that is used to neutralize excess stomach acid is more than 7.

Well, if an antacid is the opposite if an acid, the substance would be above 7 on the pH scale, because it neutralizes the acid.

never [62]

Answer:

Reaction follows frieldel-craft alkylation mechanism

Explanation:

  • Reaction between benzene and chloroform in the presence of AlCl_{3} follows friedel-craft alkylation of benzene
  • Firstly, one equivalent of benzene adds onto chloroform by replacing one equivalent of Cl from chloroform.
  • Remaining two equivalent of Cl in chloroform are similarly replaced by two equivalent of benzene to produce triphenylmethane
  • Reaction mechanism has been shown below

when an electron gets closer to the nucleus does the attraction or repulsion grow weaker or stronger?
klasskru [66]

Answer:

Weaker

Explanation:

Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).

NADH and FADH 2 are important in cellular respiration because they deliver high-energy electrons to the electron transport syste
IceJOKER [234]

Answer:

Electron transport produces 3 ATP molecule(s) per NADH molecule and 2 ATP molecules(s) perFADH 2 molecule.

Explanation:

The mechanism by which ATP is produced is explained by the theory of chemosmotic coupling.

This theory establishes that the synthesis of ATP in cellular respiration comes from an electrochemical gradient existing between the internal membrane and the space of the intermembrane of the mitochondria, through the use of the energy of NADH and FADH2 that have been formed by the rupture of molecules rich in energy, such as glucose.

You are provided with a stock solution with a concentration of 1.0x10-5 M. You will be using this to make two standard solutions
artcher [175]

Answer:

1. V₁ = 2.0 mL

2. V₁ = 2.5 mL

Explanation:

<em>You are provided with a stock solution with a concentration of 1.0 × 10⁻⁵ M. You will be using this to make two standard solutions via serial dilution.</em>

To calculate the volume required (V₁) in each dilution we will use the dilution rule.

C₁ . V₁ = C₂ . V₂

where,

C are the concentrations

V are the volumes

1 refers to the initial state

2 refers to the final state

<em>1. Perform calculations to determine the volume of the 1.0 × 10⁻⁵ M stock solution needed to prepare 10.0 mL of a 2.0 × 10⁻⁶ M solution.</em>

C₁ . V₁ = C₂ . V₂

(1.0 × 10⁻⁵ M) . V₁ = (2.0 × 10⁻⁶ M) . 10.0 mL

V₁ = 2.0 mL

<em>2. Perform calculations to determine the volume of the 2.0 × 10⁻⁶ M solution needed to prepare 10.0 mL of a 5.0 × 10⁻⁷ M solution.</em>

C₁ . V₁ = C₂ . V₂

(2.0 × 10⁻⁶ M) . V₁ = (5.0 × 10⁻⁷ M) . 10.0 mL

V₁ = 2.5 mL
