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!

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

Recall 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

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

The purpose of both mitosis and meiosis is to increase the number or population of cells in the body.

Mitosis produces two diploid (2n) cells that are identical to the original parent cell whereas meiosis produces four haploid (n) cells that are different from the original parent cell.

Mitosis occurs in somatic cells whereas meiosis occurs in reproductive cells.

So we can conclude that the purpose of both mitosis and meiosis is to increase the number or population of cells in the body.

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

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

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

0.000225 moles of Mg^2+ yields 0.000225 moles of precipitate.

Hence, a precipitate is formed.

Gluons act as exchange particles and are known as gauge bosons. They are involved in the forces within the atom as a strong nuclear force that binds the nucleus. Thus, option D is correct.

A strong nuclear force is a type of interaction that is present inside the atom and involves the nucleus. They bind the quarks to make the neutron and the proton, sub-atomic particles.

The strong nuclear force holds the atomic nucleus together and depends on the spin but not the charge. These forces are due to the interaction between the gluons and are stronger than the chemical bonds. The exchange of the mesons results in nucleons that lead to a strong nuclear force.

Therefore, option D. the gluons are responsible for the strong nuclear forces that bind the nucleus.

Explanation:

First we will employ the ideal gas law to determine the number of moles of nitrogen gas.

PV=nRT

P=2 atm

V=20L

R=0.08206*L*atm*mol^-1*K^-1

T=323.15 K

Thus, 2atm*20L=n*0.08206*L*atm*mol^-1*K^-1*323.15K

K, atm, and L cancels out. Thus n=2*20mol/0.08206*323.15=1.5 moles

Lastly, we must convert the number of moles to grams. This can be done by dividing the number of moles by the molar mass of nitrogen gas, which is 14 grams.

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.

1129.9 grams of rock salt, NaCl needs to be added to a 3.78 kg of ice, to get the temperature to drop to -19C .

Freezing point depression refers to a property of solutions where addition of a solute lowers the normal freezing point of the solvent.

The Blagden's Law given as the equation above is used to determine the freezing point depression of ice:

where;

For NaCl, i = 2

Kf for water/ice = 1.86 °C kg/mol

molalityof NaCl = (mass/molar mass

l)/kg of ice

molar mass of NaCl = 58.5

mass of ice = 3.78 kg

Let molality of NaCl = m

ΔT = 19 °C

Substituting the values:

19 = 2 x 1.86 °C kg/mol x m

m = 5.11 mol/kg

mass of NaCl = 5.11 × 3.78 × 58.5

mass of NaCl = 1129.9 g

Therefore, the mass in grams of rock salt, NaCl that needs to be added to a 3.78 kg of ice, to get the temperature to drop to -19C is 1129.9 g
