Answer : Yes , solution of $H_2SO_4$ contains ions.

Explanation:

The ionization reaction of sulfuric acid is given by the chemical equation, which follows:

$H_2SO_4(aq)\rightarrow 2H^+(aq)+SO_4^{2-}(aq)$

The sulfuric acid solution contains $H^+\&SO_4^{2-}$ ions.

By stiochoimetery of the reaction;

In 2 mole of sulfuric acid solution there are 1 mole of [trex]H^+[/tex] ions and 1 mole of sulfate ions ( $SO_4^{2-}$ ).

It has the molecular formula H2SO4. It is soluble in water at all concentrations to form a sulfuric acid solution. In the solution, a mole of sulfuric acid separates into a mole of negatively charged sulfate ions, or SO4(2-), and 2 moles of positively charged hydronium ions, or H3O+.

What came first, Layer D or Rock E? Layer D Rock E

Leno4ka [110]

Answer:

Layer D

Explanation:

First means older.

Rock E is an intrusion, so it is younger than all the layers it pass through. Apparently, Rock E is the youngest layer. So, Layer D is came before Layer E.

Hope this helps!

Have a great day :)

A 112 gram sample of an unknown metal was heated from 0.0C to 20.0C. The sample absorbed 1004 J of energy. What was the specific

worty [1.4K]

Answer:

The specific heat of the sample unknown metal is approximately 0.45 J/g °C.

General Formulas and Concepts:
Thermodynamics

Specific Heat Formula: $\displaystyle q = mc \triangle T$

m is mass (g)
c is specific heat capacity (J/g °C)
ΔT is the change in temperature

Explanation:

Step 1: Define

Identify variables.

m = 112 g

ΔT = 20.0 °C

q = 1004 J

Step 2: Solve for c

Substitute in variables [Specific Heat Formula]: $\displaystyle 1004 \ \text{J} = (112 \ \text{g})(c)(20.0 \ ^{\circ} \text{C})$
Simplify: $\displaystyle 1004 \ \text{J} = (2240 \ \text{g} \ ^\circ \text{C})c$
Isolate c: $\displaystyle c = 0.448214 \ \text{J} / \text{g} \ ^\circ \text{C}$
Round [Sig Figs]: $\displaystyle c \approx 0.45 \ \text{J} / \text{g} \ ^\circ \text{C}$

∴ specific heat capacity c is equal to around 0.45 J/g °C.

Perform the following operationand express the answer inscientific notation.7.00x10^5 - 5.00x10^4

11Alexandr11 [23.1K]

Taking into account the scientific notation, the result of the subtraction is 6.5×10⁵.

<h3>Scientific notation</h3>

First, remember that scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.

<h3 /><h3>Subtraction in scientific notation</h3>

You want to subtract two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 5.

Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 5.00×10⁴=0.500×10⁵

Taking the quantities to the same exponent, all you have to do is subtract what was previously called the number "a". In this case:

7.00×10⁵ - 0.500×10⁵= (7.00- 0.500)×10⁵= 6.5×10⁵

Finally, the result of the subtraction is 6.5×10⁵.
