According to the kinetic molecular theory what happens to a liquid then it is transferred from one container to another

sweet-ann [11.9K]

Given that the liquid conserves the volume, when it is changed from one container to another, the kinetic molecular theory predicts no change in the velocity of the molecules, which means that the temperature will not change.

Working on-board a research vessel somewhere at sea, you have (carefully) isolated 12.5 micrograms (12.5 ×10–6 g) of what you ho

Answer:

The value is $Z = 311.33 \ g/mol$

Explanation:

From the question we are told that

The mass of saxitoxin is $m = 12.5 mg = 12.5 * 10^{-6} g$

The volume of water is $V = 3.10 mL = 3.10 *10^{-3} L$

The osmotic pressure is $P = 0.236 = \frac{0.236}{760} = 3.105 * 10^{-4} atm$

The temperature is $T = 19^oC = 19 + 273 = 292 \ K$

Generally the osmotic pressure is mathematically represented as

$P = C * T * R$

Here R is the gas constant with value

$R = 0.0821 ( L .atm /mol. K)$

and C is the concentration of saxitoxin

$3.105 * 10^{-4} = C * 0.0821 * 292$

$C = 1.295 *10^{-5} mol/L$

Generally the number of moles of saxitoxin is mathematically represented as

$n = C * V$

=> $n = 1.295 *10^{-5} *3.10 *10^{-3}$

=> $n = 4.015 *10^{-8} \ mol$

Generally the molar mass of saxitoxin is mathematically represented as

$Z = \frac{m}{n}$

=> $Z = \frac{12.5 * 10^{-6}}{ 4.015 *10^{-8}}$

=> $Z = 311.33 \ g/mol$

Identify the combustion reaction

TiliK225 [7]

Answer:

C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O

Explanation:

Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.

As a result, this is the sole reaction that obeys the general combustion equation.

In a particular redox reaction, MnO2 is oxidized to MnO4– and Ag is reduced to Ag. Complete and balance the equation for this re

postnew [5]

You didn't put a + charge on one of the Ag. It has to be on the left side

2H2O + MnO2 ==> MnO4^- + 3e + 4H^+

Ag^+ + e ==> Ag^+
Those are the two BALANCED half reactions. Multiply equation 1 by 1 and equation 2 by 3 and add them.

When two amino acids condense to form a dipeptide, what is the other product of the reaction? enter the molecular formula?

Viktor [21]

When amino acids are linked together, they form a peptide bond. When it joins two amino acids, it forms a dipeptide bond. When a long chain of amino acids are joined by peptide bonds, it becomes a protein. As shown in the picture, it loses H-OH molecules. So, it will appear in the product side as a H₂O molecule.
