Answer:

Yes it is a Heterogenous mix because we know a piece of notebook paper comes from a tree and we know a tree is a amplafier for fire which is why it is used as a element and a compound so it is a mix

Which of the following results from acid deposition? View Available Hint(s) Which of the following results from acid deposition?

ASHA 777 [7]

Answer:

Objects made of stone, like marble headstones, are worn away.

Explanation:

Acid deposition on earth is mostly as a result of acid rain. Acid rain forms which oxides of non-metals such as nitrogen and carbon dissolves in rain water to produce weak acid.

This weak acid that is produced easily wears away materials made up of marble and other sculptures. The most active of the acid is weak carbonic acid produced by dissolution of carbon dioxide in rain water.

You need to use a dilute hydrochloric acid solution in an experiment. However, the only bottle of hydrochloric acid in your lab’

mr_godi [17]

The pH of the diluted HCl solution is 1.3.

Explanation:

Given:

The concentrated HCl solution of 8.0 M. The 1.5 mL of 8.0 M HCl is diluted with water to 250 mL volume.

To find:

The pH of the diluted HCl solution.

Solution

The concentration of the HCl solution before dilution = $M_1=8.0 M$
The volume of the HCl solution taken for dilution = $V_1=1.5 ml$
The concentration of the HCl solution after dilution = $M_2=?$
The volume of the HCl solution after dilution = $V_2=250 mL$

Using the Dilution equation:

$M_1V_1=M_2V_2\\8.0M\times 1.5ml=M_2\times 250 mL\\M_2=\frac{8.0M\times 1.5ml}{250 mL}=0.048 M$

The concentration of diluted HCl solution = 0.048 M

$HCl(aq)\rightarrow H^+(aq)+Cl^-(aq)$

In the 1 M solution of HCl, there are 1 M of hydrogen ion, then the concentration of hydrogen ions in 0.048 M of HCl will be:

$[H^+]=1\times 0.048M=0.048 M$

The pH of the diluted HCl solution :

$pH=-\log [H^+]\\=-\log [0.048M]=1.18 \approx 1.3$

The pH of the diluted HCl solution is 1.3.

Give the major force between ethanol and water. dipole-dipole dispersion hydrogen bonding ion-ion ion-dipole

Komok [63]

Answer:

HYDROGEN BONDING

Explanation:HYDROGEN BONDING is the major intermolecular force and interaction taking place when water and ethanol are mixed.

Hydrogen bond is a weak inter-molecular force of attraction which occurs when the partially charged Negative end of an oxygen atom from one oxygen molecule attracts and interacts with the partially charged Positive end of the Hydrogen atom in another Molecule, Hydrogen bonds are also known as dipole-dipole bonds.
