Answer:
![V_{HI}=236LHI](https://tex.z-dn.net/?f=V_%7BHI%7D%3D236LHI)
Explanation:
Hello,
In this case, for the given balanced chemical reaction:
![H_2(g)+I_2(g)\rightarrow 2HI(g)](https://tex.z-dn.net/?f=H_2%28g%29%2BI_2%28g%29%5Crightarrow%202HI%28g%29)
Thus, since hydrogen and hydrogen iodide are in a 1:2 mole ratio, we can easily compute the yielded volume as shown below:
![V_{HI}=118LH_2*\frac{2molHI}{1molH_2} \\\\V_{HI}=236LHI](https://tex.z-dn.net/?f=V_%7BHI%7D%3D118LH_2%2A%5Cfrac%7B2molHI%7D%7B1molH_2%7D%20%5C%5C%5C%5CV_%7BHI%7D%3D236LHI)
Thus, is possible, due to the Avogadro's law which allows to relate moles and volume by a directly proportional relationship.
Regards.

Answer:
Root mean squared velocity is different.
Explanation:
Hello!
In this case, since we have a mixture of oxygen and nitrogen at STP, which is defined as a condition whereas T = 298 K and P = 1 atm, we can infer that these gases have the same temperature, pressure, volume and moles but a different root mean squared velocity according to the following formula:
![v_{rms}=\sqrt{\frac{3RT}{MM} }](https://tex.z-dn.net/?f=v_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3RT%7D%7BMM%7D%20%7D)
Since they both have a different molar mass (MM), nitrogen (28.02 g/mol) and oxygen (32.02 g/mol), thus we infer that nitrogen would have a higher root mean squared velocity as its molar mass is less than that of oxygen.
Best regards!
Acid-base conjugate pair forms when the element donates a proton and another species acquires it.
and
are the base-conjugate acid pair.
<h3>What is base-conjugate acid pair?</h3>
Acids are the species or element and compounds that donates proton or hydrogen ions to form a conjugate base.
Bases are the elements or compounds that acquires protons or hydrogen ions and form a conjugate acid pair.
Conjugate acids and bases are the species or the products formed when the protons or hydrogen ions are increased or decreased in their chemical structures.
The reaction can be shown as,
![\rm H_{2}PO_{4}^{-} + H_{2}O \leftrightarrows H_{3}O^{+} + HPO_{4}^{2-}](https://tex.z-dn.net/?f=%5Crm%20H_%7B2%7DPO_%7B4%7D%5E%7B-%7D%20%2B%20H_%7B2%7DO%20%5Cleftrightarrows%20H_%7B3%7DO%5E%7B%2B%7D%20%2B%20HPO_%7B4%7D%5E%7B2-%7D)
From the reaction, it can be said that the water molecule acquired the hydrogen or the proton ions and the hydronium ion produced as a result is the conjugate acid of the water base.
Therefore,
and
are the base-conjugate acid pair.

The sensitivity of electronic balance is 0.3 mg
Converting 0.3 mg to g:
g
So, the mass of a substance weighed on the balance can be measured accurately up to four decimal places.
Given the mass of sample is 1.2300 g. The number of significant figures in the measurement will be 5 because the balance can measure the mass of a sample accurately up to four decimal points, all the digits in the measurement will be significant.
