Acetic acid (CH3COOH) reacts with water to form the acetate ion and the hydronium ion: Upper C upper H subscript c upper C upper

O upper o upper H (a q) plus upper H subscript 2 upper o (l) double arrow upper C upper H subscript 3 upper C upper o upper O superscript minus (a q) plus upper H subscript 3 upper o superscript plus (a q). At equilibrium, the concentration of CH3COOH is 2. 0 × 10–1 M, the concentration of CH3COO– is 1. 9 × 10–3 M, and the concentration of H3O is 1. 9 × 10–3 M. What is the value of Keq for this reaction? 1. 8 × 10–5 5. 5 × 104 9. 5 × 10–3 1. 1 × 102.

The correct option is (A).

<h3>What is acetic acid?</h3>

Acetic acid is an organic compound also called ethanoic acid. It is a colorless liquid with a chemical formula   (CH_3COOH).

It has antibacterial and antifungal properties.

When acetic acid is reacted with water, it completely dissolves in it.

Thus, the correct option is A, \bold{1.8 \times 10^-^5}.

Aleks04 [339]

Answer:

Nickel and Titanium

Explanation:

Nitinol is an alloy of Nickel and Titanium. It posesses two properties such that,

  • The shape memory effect
  • Super elasticity

Shape memory is the ability of nitinol to undergo deformation at one temperature, stay in its deformed shape when the external force is removed.

Superelasticity is the ability for the metal to undergo large deformations and immediately return to its undeformed shape upon removal of the external load.

Hence, the correct option is (b) "Nickel and Titanium".

Find the empirical formula of the compound ribose, a simple sugar often used as a nutritional supplement. A 14.229 g sample of r
MakcuM [25]

Answer:

CH2O

Explanation:

Firstly, we need to convert the masses of the elements to percentage compositions. This can be done by placing the mass of each element over the total mass multiplied by 100% . We can start with carbon.

C = 5.692/14.229 * 100 = 40%

O = 7.582/14.229 * 100 = 53.29%

H = 0.955/14.229 * 100 = 6.71%

We then proceed to divide each percentage composition by their atomic mass of 12, 16 and 1 respectively.

C = 40/12 = 3.333

O = 53.29/16 = 3.33

H = 6.71/2 = 6.71

Dividing by the smaller value which is 3.33

C = 3.33/3.33 = 1

O = 3.33/3.33= 1

H = 6.71/3.33 = 2

The empirical formula of the compound ribose is CH2O

The reaction between iron(II) oxide and carbon monoxide produces iron and carbon dioxide. How many moles of iron can be obtained
aleksandrvk [35]

Answer:

1.5 moles of Fe produced.

Explanation:

Given data:

Moles of FeO react = 1.50 mol

Moles of iron produced = ?

Solution:

Chemical equation:

FeO + CO       →       Fe + CO₂

Now we will compare the moles of ironoxide with iron.

                           FeO          :           Fe

                              1             :             1

                             1.5           :           1.5

Thus from 1.5 moles of FeO 1.5 moles of Fe are produced.
