moles in 9.01x10^23 molecules water

Answers

Answer:

The answer is 1.50 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.01 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{9.01}{6.02} \\ = 1.496677740...[/tex]

A student found a 500 cm3 sample of vinegar. Knowing that vinegar is a solution of ethanoic acid (CH3COOH) and water, this student decided to take a 25.0 cm3 sample, dilute it with 25.0 cm3 of water and then react it with sodium hydroxide. The dilute sample required 37.0 cm3 of 0.850 mol dm–3 sodium hydroxide solution to react entirely with it via the following reaction:

CH3COOH(aq) + NaOH(aq) → NaCH3COO(aq) + H2O(l)

A) 31.22
B) 39.98
C) 7.80
D) 79.96
E) 15.61

Please give an answer and an explanation, thanks!

Answers

Answer:

A) 31.22

Explanation:

The reaction of sulfuric acid with NaOH is:

H₂SO₄ + 2 NaOH → Na₂SO₄ + 2H₂O

To solve this problem we need to determine the moles of acid that will react, and, using the chemical equation we can determine the moles of NaOH and the volume that a 0.2389M NaOH solution would require to neutralize it.

Moles H₂SO₄ (Molar mass: 98.08g/mol):

0.9368g * 39.04% = 0.3657g H₂SO₄ * (1mol / 98.08g) =

3.7289x10⁻³moles H₂SO₄

And moles of NaOH that you require to neutralize the acid are:

3.7289x10⁻³moles H₂SO₄ * (2 moles NaOH / 1 mole H₂SO₄) =

7.4578x10⁻³ moles NaOH

Using a 0.2389M NaOH solution:

7.4578x10⁻³ moles NaOH * (1L / 0.2389mol) = 0.03122L = 31.22mL

Right answer is:

A) 31.22

2. What type of bonding would be expected between the following atoms?
a. Li and F
c. I and Br
b. Cu and S
d. S and O

Answers

a.) covalent
c.) covalent
b.) ionic
d.) covalent

Considering the definition of covalent and ionic bond, the type of bonding that would be expected between the following atoms is:

Li and F: Ionic Bond I and Br: Covalent Bond Cu and S: Ionic Bond S and O: Covalent Bond

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.  

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Taking into account the previous definitions, it is first necessary to know if the elements are metallic or non-metallic:

Lithium Li: Metallic atoms Flour F: Non-metallic atoms Iodine I: Non-metallic atomsBromine Br: Non-metallic atomsCopper Cu: Metallic atoms Sulfur S: Non-metallic atoms Oxygen O: Non-metallic atoms

Now you can determine the type of bond of the following pairs of elements:

Li and F: Metallic atoms - Non-metallic atoms: Ionic Bond I and Br: Non-metallic atoms - Non-metallic atoms: Covalent Bond Cu and S: Metallic atoms - Non-metallic atoms: Ionic Bond S and O: Non-metallic atoms - Non-metallic atoms: Covalent Bond

A cart has a mass of 35kg and a speed of 1.2m/s. What is its kinetic energy

Answers

Answer:

The answer is 25.2 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question we have

[tex]KE = \frac{1}{2} \times 35 \times {1.2}^{2} \\ = 17.5 \times 1.44 [/tex]

We have the final answer as

25.2 J

Hope this helps you

Answer:

25.2 J

Explanation:

Using the kinetic energy formula:

KE = [tex]\frac{1}{2}[/tex]m v²

Plug in the given values:

KE = [tex]\frac{1}{2}[/tex] (35 kg) · (1.2 m/s)²

KE = [tex]\frac{1}{2}[/tex] (35) · 1.44

KE = 17.5 · 1.44

KE = 25.2 J

There is a kinetic energy of 25.2 Joules.

The healthy chicks will mob the weak ones, the older chicks (even by a day) will pick on the younger ones. Temperature extremes will threaten them as they need warm, humid conditions with gradual drops in surrounding temps in the brooder box. Early disease is sometimes a problem and all chicks should be started on medicated chick feed for the first few weeks to prevent several digestive diseases. Even the water dispenser can be a threat as newly hatched chicks will immerse themselves in an open water container so care should be taken to supply water in a self feeding covered dish.
