Answer: Matter is the thing which occupied space and volume.

Explanation: In chemistry or in general life, we define matter as the susbtance which occupied space and make volume for itself. Thus everything on the eart occupied some kind of space thus they all are applicable to fall under the category of Matter.

There are various kinds of forces which hold together the matter depending on the type of susbtances. Like sodium chloride crystal lattice has ionic bonding between the ions whereas carbon skeleton has covalent bonding, water flowing in the river have hydrogen bonding.

These matter are made up of protons, atoms, electrons, neutrons, molecules etc.

What is the Bronsted acid of H2PO4- + OH-. ---- HPO42- + H2O?

RoseWind [281]

Answer:

The bronsted- Lowry acid is H₂PO₄⁻

Explanation:

Bronsted-Lowry acid donates a proton (H⁺)

H₂PO₄⁻ + OH⁻ → HPO₄²⁻ + H₂O

In the reaction above, H₂PO₄⁻ is donating the proton to OH⁻ resulting in H₂O and the deprotonated species. This makes it a bronsted-Lowry acid.

Sulfur reacts with oxygen and creates two compounds. Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen. Compound B

spayn [35]

Answer:

The mass ratio of oxygen rounded to the nearest whole no. 3 : 2

Explanation:

According to Law of Multiple proportion when two elements combine to make two or more different compounds, the mass ratio of the two element in the first compound, when divided by the mass ratio of the second compound , form a simple whole number ratio.

Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen

$\frac{1.34}{0.86}= 1.5$

Compound B contains 11.63 g of sulfur for every 10.49 g of oxygen

$\frac{11.643}{10.49}= 1.0$

Ratio of oxygen in each compound

always put the larger number over the smaller number.

$\frac{CompoundA}{Compound B}=\frac{1.5}{1.0}=\frac{3}{2}$

Consider a voltaic cell where the anode half-reaction is Zn(s) → Zn2+(aq) + 2 e− and the cathode half-reaction is Sn2+(aq) + 2 e

notsponge [240]

Answer: The concentration of $Sn^{2+}$ in the cell is $9.0\times 10^{-3}M$

Explanation:

We are given:

Oxidation half reaction: $Zn(s)\rightarrow Zn^{2+}(aq.)+2e^-$ $E^o_{Zn^{2+}/Zn}=-0.76V$

Reduction half reaction: $Sn^{2+}(aq.)+2e^-\rightarrow Sn(s)$ $E^o_{Sn^{2+}/Sn}=-0.136V$

The substance having highest positive $E^o$ potential will always get reduced and will undergo reduction reaction. Here, fluorine will undergo reduction reaction will get reduced.
