Balance the equation: Ba(OH)2(aq) + H3PO4(aq)

alexgriva [62]

The products of the unbalanced reaction are as follows:

Ba(OH)₂ (aq) + H₃PO₄(aq) → Ba₃(PO₄)₂(s) + H₂O(l)

This is an acid base reaction where Ba(OH)₂ is the base and H₃PO₄ is the acid. Acid base reaction is also known as neutralization reaction where the acid and base react with each other to form salt and water. In this reaction Ba₃(PO₄)₂ is the salt. Also barium phosphate (Ba₃(PO₄)₂) is insoluble in water and forms a solid precipitate.

The balanced reaction is as follows:

3Ba(OH)₂ (aq) + 2H₃PO₄(aq) → Ba₃(PO₄)₂(s) + 6H₂O(l)

There are three Ba from Ba₃(PO₄)₂ on the product side of the equation, so to balance 3 coefficient was placed before Ba(OH)₂. Similarly, 2 coefficient was placed before H₃PO₄ on the reactant side to balance the two phosphate from Ba₃(PO₄)₂ on the product side. Finally, 6 coefficient was placed before H₂O on the product side, to balance the number of H and O atoms on both side of the equation.

What is the wavelength of a 3 x 1012 Hz infrared wave?

bulgar [2K]

Answer:

$\lambda=10^{-4}\ m$

Explanation:

Given that, $\lambda=10^{-4}\ m$

The frequency of infrared wave, $f=3\times 10^{12}\ Hz$

We need to find the wavelength of infrared wave. The relation between the frequency and the wavelength is given by :

$c=f\lambda$

where

c is the speed of light

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3\times 10^{12}}\\\\=0.0001\ m\\\\=10^{-4}\ m$

So, the wavelength of the infrared wave is $10^{-4}\ m$ .

How Can We Determine the Actual Percentage of H2O2 in a Drugstore Bottle of Hydrogen Peroxide?

djverab [1.8K]

Answer:

Measuring the volume of oxygen released

Explanation:

The hydrogen peroxide has a decomposition reaction:

$2 H_2O_2 \longrightarrow H_2O + O_2$

So, if we leave this reaction happen and we capture the oxygen released measuring its volume we can determine the percentage of peroxide.

$n_{O2}=\frac{P*V_{O2}}{T*R}$

$n_{H2O2}= 0.5*n_{O2}=0.5* \frac{P*V_{O2}}{T*R}$

$m_{H2O2}=n_{H2O2}*M_{H2O2}=M_{H2O2}*0.5* \frac{P*V_{O2}}{T*R}$

$V_{H2O2}=m_{H2O2}* \rho _{H2O2}$

$V_{H2O2}= \rho _{H2O2}*M_{H2O2}*0.5* \frac{P*V_{O2}}{T*R}$

Where:

$n_{H2O2}$ is the number of moles of H2O2
$m_{H2O2}$ is mass of H2O2
$M_{H2O2}$ is the molecular weight of H2O2
$\rho _{H2O2}$ is the density of H2O2

$Percentage=\frac{V_{H2O2}}{V_{total}}*100$

If you were a scientist, why wouldn't you use "sour taste" to identify a compound as acidic?

Eduardwww [97]

Tasting things in a scientific lab is almost universally forbidden, since many items can be quite dangerous if ingested. Also "taste" is a subjective measurement, and can mean different things to different people.

cherries on a tree freeze at -2°. The weather forecast said that tonight's low is -5° C. The old farmer sprays down his trees wi

just olya [345]

Old wives tale

Explanation:

This is an old wives tale and not scientifically correct.

Water is liquid that is known to freeze at 0° C.

The boiling point of water is also 100° C.

If the farmer sprays the cherries on the tree with water, it suggests that they will freeze faster because water has high freezing point compared to that of the cherry.
This will not in any way protect the cherries on the tree.
To prevent the cherries from freezing, he should spray them with something that has lower freezing point.
