Take note that this is S03 and not S04.

S03:Sulfite
S04:Sulfate

So the answer would be Aluminum Sulfite =)

Answer:

Name: Aluminum Sulfite

Explanation:

Systematic nomenclature: dialuminium tris [trioxosulfate (IV)]

Oxoanions: anions derived from removing H + from an oxo acid with a vulgar name:

(SO3)3^-2 (sulfite)

Metal cation according to valence number:

Al (III) or Al+3 (as a cation) (Aluminum)

There are different types of salts, in this case we have a simple salt and the nomenclature for binary substances is used when only one class of cation and one class of anion are present

So:

Al2(SO3)3: Aluminum Sulfite

In the reaction, A -----> Products, the rate constant is 3.6 x 10^−4 s−1. If the initial concentration of A is 0.548 M, what

swat32

Answer:

0.529

Explanation:

Let's consider the reaction A → Products

Since the units of the rate constant are s⁻1, this is a first-order reaction with respect to A.

We can find the concentration of A at a certain time t ( $[A]_{t}$ ) using the following expression.

$[A]_{t}=[A]_{0}.e^{-k\times t}$

where,

[A]₀: initial concentration of A

k: rate constant

$[A]_{t}=0.548M.e^{-3.6\times 10^{-4}s^{-1}\times 99.2s }$

$[A]_{t}=0.529 M$

Identify which result of a physical rather than a chemical change

Pani-rosa [81]

Explanation:

A physical change is change that alters the physical properties of matter especially its form and state.

In many cases, the change is easily reversible.

Examples are change of state such as boiling, melting, freezing, condensation, sublimation e.t.c

A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes.

Examples are combustion, rusting , precipitation, milk souring.

Chemical changes are irreversible
Physical changes do not lead to the formation of new kinds of matter.
Most physical changes requires little energy.

The pressure on a 200 milliliter sample of CO2 (g) at constant temperature is increased from

balu736 [363]

The answer for the following problem is mentioned below.

Therefore the final volume of the gas is 100 ml.

Explanation:

Given:

Initial pressure ( $P_{1}$ ) = 600 mm of Hg

Final pressure ( $P_{2}$ ) = 1200 mm of Hg

Initial volume ( $V_{1}$ ) = 200 ml

To find:

Final volume ( $V_{2}$ )

We know;

According to the ideal gas equation,

P × V = n × R × T

Where;

P represents the pressure of the gas

V represents the volume of the gas

n represents the no of moles of the gas

R represents the universal gas constant

T represents the temperature of the gas

So,

From the above mentioned equation,

P × V = constant

$\frac{P_{1} }{P_{2} }$ = $\frac{V_{1} }{V_{2} }$

Where,

( $P_{1}$ ) represents the initial pressure of the gas

( $P_{2}$ ) represents the final pressure of the gas

( $V_{1}$ ) represents the initial volume of the gas

( $V_{2}$ ) represents the final volume of the gas

So;

$\frac{600}{1200}$ = $\frac{V_{2} }{200}$

$V_{2}$ = 100 ml

Therefore the final volume of the gas is 100 ml.
