Answer:
Hydrogen is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals.
Explanation:
The limiting reagent is Copper (Cu)
First, balance the reaction before determining the limiting reactant.
Cu + 2Ag
Cu(NO3)2 + 2Ag from NO3
Take the beginning material amount and calculate the number of moles of one of the products to identify the limiting reactant. The limiting reactant is the one that produces a product with the fewest moles.
5.50×1.00/2.00=2.75
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
Copper is the limiting reactant since there are only 2.50 mol of it and only 2.50 mol of AgNO3 will result from the reaction.

Answer:
the final pressure (108.03 mmHg ) inside the container at 339 K is more than the vapor pressure of liquid octane (100 mmHg) at 339 K.
Hence,
b. Some of the vapor initially present will condense.
e. Liquid octane will be present.
Explanation:
Given that;
The vapor pressure of liquid octane, C8H18, is 100 mm Hg at 339 K
Initial volume of the container, V1 = 537 mL
Initial vapor pressure, P1 = 68.0 mmHg
Final volume of the container, V2 = 338 mL
Let us say that the final vapor pressure = P2
From Boyle's law,
P2V2 = P1V1
P2 * 338 = 68.0 * 537
338
P2 = 36516
P2 = 36516 / 338
P2 = 108.03 mmHg
Thus, the final pressure (108.03 mmHg ) inside the container at 339 K is more than the vapor pressure of liquid octane (100 mmHg) at 339 K.
Hence,
b. Some of the vapor initially present will condense.
e. Liquid octane will be present.
Ph range is 14.35.
<h3>What is PH?</h3>
PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.
