The chemical name for NaC₂H₃O₂ is sodium acetate.

Sodium acetate is a compound that consists of sodium ions (Na+) and acetate ions. It is also known by its chemical formula CH₃COONa. The compound is commonly found in both solid and aqueous forms.

Sodium acetate is produced by the neutralization reaction between acetic acid and sodium hydroxide. It can also be obtained by reacting sodium carbonate with acetic acid. The resulting product is a white crystalline solid that is highly soluble in water.

One of the notable properties of sodium acetate is its ability to act as a buffer solution, meaning it can resist changes in pH. It is often used in various applications.

Answer:

I would say the purple one!

Explanation:

Solution :

Molecular mass of NaOH is 23 g/mol .

So, number of moles of NaOH is given by :

[tex]n = \dfrac{10}{40}\ mole[/tex]

Now, we know molarity is given by :

[tex]Molarity = \dfrac{Number \ of \ moles\ of \ salute}{Volume ( in \ Liter ) }[/tex]

[tex]M = \dfrac{10}{40\times 2.4} \ M\\\\M = 0.104 \ M[/tex]

Hence, this is the required solution.

Ocean dynamics define and describe the motion of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of 1,000,000 m (35,000,000 cu ft) per second.

Surface currents, which make up only 8% of all water in the ocean, are generally restricted to the upper 4…

Answer:

[tex]c=3.71\ J/g^{\circ} C[/tex]

Explanation:

Given that,

Mass of sample, m = 996.9 g

The change in temperature of the sample, [tex]\Delta T=-70.98^{\circ}C[/tex]

Heat produced, Q = 62.9  calories = 263173.6 J

The heat released by a sample due to change in temperature is given by :

[tex]Q=mc\Delta T[/tex]

Where

c is the specific heat capacity

So,

[tex]c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{263173.6}{996.9\times 70.98}\\\\c=3.71\ J/g^{\circ} C[/tex]

So, the specific heat of ethanol is equal to [tex]3.71\ J/g^{\circ} C[/tex].

Answer:

The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules

Explanation:

As we know

Amount of heat gained

Q = mc (T2-T1)

Here,

mass of water in cup 2 (m) = 79.10 grams

Temperature of water in cup 2 = 16.8 degree Celsius

Specific heat of water (c) = 4.186 J/(g °C)

Final Temperature of water in cup 2  = 23.2 degree Celsius

Substituting the given values, we get -

Q = 79.10 * 4.186 * (23.2 -16.8) = 2119.121 Joules

The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules

Answer:

2.5

Explanation:

From the question given above, the following data were obtained:

Molarity of NaOH = 3.0x10¯³ M

pOH =?

Next, we shall determine the concentration of the hydroxide ion in the solution. This can be obtained as follow:

NaOH (aq) —> Na⁺ (aq) + OH¯ (aq)

From the balanced equation above,

1 mole of NaOH produced 1 mole of OH¯.

Therefore, 3.0x10¯³ M NaOH will also produce 3.0x10¯³ M OH¯.

Finally, we shall determine the pOH of the solution. This can be obtained as illustrated below:

Concentration of hydroxide ion [OH¯] = 3.0x10¯³ M

pOH =?

pOH = – Log [OH¯]

pOH = – Log 3.0x10¯³

pOH = 2.5

Thus, the pOH of the solution is 2.5

Answer:

234 atm

Explanation:

Answer:

2.28 M

Explanation:

Using the formula as follows;

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (L)

V2 = final volume (L)

According to the information given in this question;

C1 = 0.95M

C2 = ?

V1 = 0.60L

V2 = 0.25L

Using C1V1 = C2V2

0.95 × 0.60 = C2 × 0.25

0.57 = 0.25 C2

C2 = 0.57 ÷ 0.25

C2 = 2.28 M

Answer:

49°C

Explanation:

Let's apply the Ideal Gases Law in order to solve this question:

P . V = n . R . T

Pressure = 1 atm

Volume = 6 L

n = number of moles → 10 g. 1mol /44g = 0.227 moles

R = Ideal Gases Constant

We replace data: 1 atm . 6 L = 0.227 mol . 0.082 . T

6 atm.L / ( 0.227 mol . 0.082) = T

T° = 322 K

We convert T° from K to °C → 322 K - 273 = 49°C

Answer:

1.26moles

Explanation:

To get the number of moles (n) in an element, we divide the number of molecules of the element by Avagadro number (6.02 × 10^23)

n = no. of molecules ÷ nA (6.02 × 10^23)

According to this question, number of molecules of Neon (Ne) is 7.6 x 10^23 particles.

n = 7.6 x 10^23 ÷ 6.02 × 10^23

n = 7.6/6.02 × 10^(23-23)

n = 1.26 × 10^0

n = 1.26moles
