3.3 mol Fe(OH)3 and 6.3 mole H2SO4react according to the equation 2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O.
If the limiting reactant is Fe(OH)3, determine the amount of excess reactant that remains. Answer in units of mol.
Answer and Explanation:
2 mol of Fe(OH)3 produces 1 mol of Fe2(SO4)3 then 2.1 mol of Fe(OH)3 will produce (1)/(2) x 2.01 = 1.05 mol of Fe2(SO4)3 amount of H2O = (6)/(2) * 2.01 = 6.03 mol HO2

What is the specific heat capacity of an unknown metal if 75.00 g of the metal absorbs 418.6J of heat and the temperature rises 25.0°C?
Answer:
The specific heat capacity of the unknown metal is 0.223 [tex]\frac{J}{g*C}[/tex]
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Q= 418.6 J c= ? m= 75 g ΔT= 25 CReplacing:
418.6 J= c* 75 g* 25 C
Solving:
[tex]c=\frac{418.6 J}{75 g*25 C}[/tex]
c= 0.223 [tex]\frac{J}{g*C}[/tex]
The specific heat capacity of the unknown metal is 0.223 [tex]\frac{J}{g*C}[/tex]

can someone explain in detail how molar mass, Avogadro's number, and volume are all connected through moles? Im so confused :(
Answer:
See Explanation
Explanation:
By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...
1 mole of hydrogen atoms (H) = 1.00794 grams
1 mole of molecular hydrogen (H₂) = 2.01588 grams
1 mole of any substance = 1 formula weight in grams
1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams
In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.
For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...
Given N₂(g) + 3H₂(g) => 2NH₃(g) is assumed to be at 0°C; 1 Atm pressure.
Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)
Molecular Hydrogen = 3 molar volumes = 3 x 22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)
Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃

_________deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses
Lesson 2.12
Question 3 options:
Density
Thermohaline currents
Salinity
Polar ice caps
Answer:
its B) Thermohaline currents Sorry if its wrong but im sure this could be it
Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses
What is thermohaline currents?Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.
As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.
Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.
