An ideal gas occupies 400ml at 270 mm Hg and 65°C. If the pressure is changed to 1.4 atm and the
temperature is increased to 100°C, what is the new volume?
Answer:
113 ml
Explanation:
PV = nRT remember T must be in Kelvin Volume in L
270 * .4 = n 62.4* 338.15
n = .005118
1.4 atm = 1.4 * 760 = 1064 mm
1064 * V = .005118 * 62.4 * 373.15
V = .113 l
Which metal would cause the greatest increase in the temperature of the water in the calorimeter: the
one with the higher specific heat, or the one with the lower specific heat? Explain.
(THE EXPLANATION IS IMPORTANT)
Answer:
The one with higher specific heat
Explanation:
A metal with the highest specific heat will cause the greatest increase in temperature of water in a calorimeter because the metal would hold more heat, and then transfer it to the water.
Answer:
[tex] \sf \: \fbox{Metal \: with \: the \: higher \: specific \: heat.}[/tex]
Explanation:
HEAT:
In the universe there are only two mods of Transfer of Energy one is Heat and another is Work. That's why Heat and Work are well knowns Path function.
Specific Heat:
The specific Heat of any material is the heat gained or released by the material to raise or fall it's temperature by 1°C per unit mass of the material.
The heat gained or released (Q) is directly proportional to the mass of substance(m) and rise or fall of temp(∆T)
given by the equation,
[tex]\sf \: s = \frac{Q}{m \Delta T} [/tex]
Where S is the proportionality constant also known as specific Heat.
S.I. unit of s is joule/kg-K
C.G.S unit is cal/gm °C.
Specific heat of water: s = 4200 J/kg°C
Coming to the next important term calorimeter,
Calorimeter:
We already knew above that heat is not a form of energy it's a mod of transfer of energy, consider One Energy converted from State A to State B then the total heat(Transferred energy) during the process is measured by a device known as Calorimeter.
Now, coming to your question.
Consider a metal, with lower specific heat (s), the equation we derived above tells that specific heat is directly proportional to energy per unit change in temperature, that means if specific heat will be low, lesser amount of Energy(Heat) will be produced which will cause the minor increase in the temperature.
Which is a contradiction hence the answer would be Metal with the higher specific heat.
This is the final answer!

b. 111 g NaCl
c. 55.4 g NaCl
222 g NaCl
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Physical chemistry, and Stochiometry.
So we balance the equation as,
2Na + Cl2 ===> 2NaCl
The required reaction is as:
2Na+ Cl2 = 2NaCl
2 moles Na = 2×23 g = 46g,1 mole Cl2 = 2×35.5g=71g
Now,71g Cl2 reacts with 46g Na,
Therefore, 67.2g Cl2 reacts with 46×67.2/71= 43.54g Name
The rest Na = (55–43.54)g=11.46g
That means Cl2 is a limiting reactant.
Again,2 moles NaCl=2(23+35.5)g=117g
Then,71g Cl2 produce 117g NaCl
Therefore,67.2g Cl2 produce 117×67.2/71 = 110.74g NaCl
hence the correct option is, b.) 111 g NaCl

what is packing fraction ?
state the formula used to calculate it.
thankyou ~
Answer:
please mark me brainliestExplanation:
Packing fraction is defined as a way of expressing the variation of isotopic mass from whole mass number (atomic mass). This fraction can have positive or can have negative sign. A positive packing fraction describes a tendency towards instability.The equation for packing fraction is: Packing fraction = (N atoms) x (V atom) / V unit cell. N atoms is the number of atoms in a unit cell. V atom is the volume of the atom, and V unit cell is the volume of a unit cell. Substitute the number of atoms per unit cell into the equation.What volume (in L) of 1.40 M FeBr₂ would be required to obtain 0.500 moles of Br⁻ ions?
The volume, in Liters, that would be required to obtain 0.500 moles of Br ions from 1.40 M FeBr2 will be 0.36 L
Stoichiometric calculationRecall that:
Molarity = mole/volume
In this case, molarity = 1.40 M and moles = 0.500 moles
Thus:
Volume = mole/molarity = 0.500/1.40 = 0.36 L

Temperature and _____________________ control the phase of a substance. A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different conditions of temperature and pressure. A phase diagram typically has ______ regions, each representing a different phase and three curves that ________________________ each phase.
Temperature and pressure control the phase of a substance. A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different conditions of temperature and pressure. A phase diagram typically has three regions, each representing a different phase, and three curves that separate each phase.
In a phase diagram, the three regions correspond to the three common phases of matter: solid, liquid, and gas. The curves that separate each phase are known as phase boundaries or phase transition lines. These curves represent the conditions (specific combinations of pressure and temperature) at which phase transitions occur, such as melting (solid to liquid), boiling (liquid to gas), or sublimation (solid to gas).
Each phase boundary on the phase diagram represents the equilibrium between two phases, and the triple point, where all three phase boundaries intersect, represents the conditions where all three phases coexist in equilibrium.
Phase diagrams are essential tools in understanding the behavior of substances under different temperature and pressure conditions and are used in various fields, including chemistry, physics, and materials science. They provide valuable information about the stability and existence of different phases and the conditions under which phase transitions occur.

Will a precipitate form if you mix 75.0 mL of a NaOH solution with pOH of 2.58 if it is mixed with 125.0 mL of a 0.0018 M MgCl2 solution
A precipiatate of mass 0.013 g is formed when you mix 75.0 mL of a NaOH solution with pOH of 2.58 and 125.0 mL of a 0.0018 M MgCl2 solution
What is stoichiometry?In stoichiometry, calculations are made based on mass - mole or mole - volume relationships. First we must put down the balanced reaction equation; 2NaOH(aq) + MgCl2(aq) -----> Mg(OH)2(s) + 2NaCl(aq)
Now Ionically;
2OH^-(aq) + Mg^2+(aq) -----> Mg(OH)2(s)
Concentration of OH^- = Antilog (-2.58) = 2.6 * 10^-3 M
Number of moles of OH^- = 2.6 * 10^-3 M * 75/1000 = 0.000195 moles
Concentration of Mg^2+ = 0.0018 M
Number of moles of Mg^2+ =0.0018 M * 125/1000 = 0.000225 moles
Since;
1 mole of Mg^2+ reacts with 2 moles of OH^-
x moles of Mg^2+ reacts with 0.000195 moles of OH^-
x = 0.0000975 moles
Mg^2+ is the limiting reactant.
1 mole of Mg^2+ yields 1 mole of the precipitate
