Answer:

Six

The coordination number of sodium is 6. Likewise, six sodium ions immediately surround each chloride ions, making the coordination number of chloride also equal to 6. Because the formula unit of sodium chloride displays a 1:1 ratio between the ions, the coordination numbers must be the same.

Sakura tested the pH of several solutions. Which substances are acidic? Check all that apply. Cola-flavored soda: 2. 6 cranberry

Archy [21]

Cola-flavored soda: 2. 6 -Acidic

cranberry juice: 2. 9 -Acidic

dish soap: 7. 3 -Basic

pickle juice: 5. 5 -Acidic

seawater: 8. 0 -Basic

lye soap: 13. 0. -Basic

pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.

The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.

Below 7 are all acids and the above 7 are all basic.

Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

Two students are given different samples of a substance and are instructed to determine the properties of the substance.

Hunter-Best [27]

The complete question is given below:

Two students are given different samples of a substance and are instructed to determine the properties of the substance.

Which statement describes a property that will be the same for both students?

A. color because it is an extensive property

B. mass because it is an extensive property

C. boiling point because it is an intensive property

D. volume because it is an intensive property .

ANSWER

The correct option is C.

The physical properties of substances are divided into two, intensive and extensive properties.

Intensive properties refers to those features of a substance that do not depend on the quantity of the material that is available. Whether the sample available is big or small, the intensive properties remain the same. Examples of intensive properties are: melting point, boiling point, refractive index, hardness, density color, etc. This question is asking us to look for an intensive property.

Extensive properties refers to those characteristics of a substance that depend on the amount of substance present. Examples of these properties are: mass, volume, size, weight, length, etc.

From the options given, option A is wrong because color is not an extensive property, it is intensive. Option B is wrong because the mass depend on the amount of sample given and the same thing apply to option D.

The correct option is C, because no matter the quantity of that substance that you have, the boiling point will always remains the same.

DUE TODAY EXTREMELY IMPORTANT PLEASE PLEASE PLEASE HELP ME ASAPPPPPPPP CHEMISTRY!!!!!!!!!!!!!!!!!!! I WOULD APPRECIATE IT ALOT T

Here's what I get

Explanation:

3. Molar concentration by formula.

$\begin{array}{rcl}M_{\text{a}}V_{a} & = & M_{\text{b}}V_{b}\\M_{a} \times \text{0.025 00 L} & = & \text{0.3840 mol/L} \times \text{0.034 52 L}\\0.025 00M_{a}\text{ L} & = & \text{0.013 26 mol}\\M_{a}&= &\dfrac{\text{0.013 26 mol}}{\text{0.025 00 L}}\\\\& = &\textbf{0.5302 mol/L}\end{array}$

(i) Comparison of molar concentrations

The formula gives a calculated value of 0.5302 mol·L⁻¹.

Dimensional analysis gives a calculated value of 0.1767 mol·L⁻¹.

The first value is three times the second.

It is wrong because the formula assumes that the acid supplies just enough moles of H⁺ to neutralize the OH⁻ from the NaOH.

Instead, I mol of H₃PO₄ provides 3 mol of H⁺, so your calculated concentration is three times the true value.

(ii) When is the formula acceptable?

The formula is acceptable only when the molar ratio of acid to base is 1:1.

Examples are

HCl + NaOH ⟶ NaCl + H₂O

H₂SO₄ + Ca(OH)₂ ⟶ CaSO₄ + 2H₂O

H₃PO₄ + Al(OH)₃ ⟶ AlPO₄ + 3H₂O
