Answer

When oxidation and reduction takes place simultaneously it is called a redox reaction.

Explanation:

Oxidation is the process in which an electron loses an atom, whereas, in reduction an atom gains an atom. when both of these reactions occur simultaneously the process is known as redox.

When a substance is being oxidized, it loses an electron or a hydrogen atom and gains an oxygen atom. Whereas, in reduction it gains an hydrogen atom and loses an oxygen atom. These two cannot happen individually and will always happen simultaneously.

KonstantinChe [14]

Answer:

Explanation:0.493 M NaOH means 0.493 mol NaOH/L

mols

mols = ------ x L

L

mols = M x V

In a titration procedure, 40.57 mL of 0.493 M NaOH solution was used. How many mols NaOH did this volume of NaOH solution contain?

mols = M x V

0.493 mols NaOH

mols = ----------------------- x 0.04057 L

L

mols = 0.0200 mols NaOH

<h3>1. Br₂ decreased : system moving to the left</h3><h3>2. HBr increased : system moving to the left</h3><h3>Further explanation</h3>

In the equilibrium system, according to Le Chatelier, if there is a reaction there will be action

<h3>Reaction = - action</h3>

If the concentration of one component is enlarged, the system reaction is to reduce the component, and vice versa, if the concentration of one component is reduced, the reaction system is to add to the component

From reaction :

H₂(g) + Br₂(g) ⇔ 2HBr(g)

  • After the concentration of Br₂ is decreased :

The system will react by increasing the concentration of reagents by moving to the left

  • After the concentration of HBr is increased.

The system will react by decreasing the concentration of product by moving to the left

If you dissolve 0.1 mol of formic acid in 1 L of water, ther esulting solution contains 0.004 mol of H₃O+. Based on this informa
zhuklara [117]

In an ideal case, the acid would completely protonate. such an acid would be a strong acid.  Dissociation of Formic acid looks like:

HCOOH + H₂O → COOH⁻ + H₃O⁺

one mole of formic acid should give one mole of Hydronium(H₃O⁺) ions

similarly, 0.1 moles of formic acid should produce 0.1 moles of hydronium ions. but we know that it is not the case, a much lesser amount is actually formed.

Which means that Formic acid did not completely dissociate into COOH⁻ and H⁺ ions.

Hence, Formic Acid is a weak acid

A 83.2 g sample of metal at 90.31 oC is added to 41.82 g of water that is initially at 19.93 oC. The final temperature of both t
MissTica

Answer: 0.2885J/g°c

Explanation:

Loss of heat of metal = Gain of heat by the water

Therefore

-Qm = +Qw

Where

Q = mΔTCp

Q = heat

M= mass

ΔT = T.f - Ti

Ti= initial temperature

T.f= final temperature

Cp= Specific heat (m is metal, w is water)

-Qm = +Qw

-[m(T.f-Ti)Cpm] = m(T.f-Ti)Cpw

Therefore

-[83.2g(28.42-90.31)Cpm] = 41.82g(28.42-

19.93)4.194J/g°c

Cpm = 1485.54÷ 5149.25

Cpm = 0.2885J/g°c

Therefore , the specific heat of the metal is 0.2885J/g°c
