A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.
Answer:
46.73ºC
Explanation:
The sheets will change heat to achieve the thermal equilibrium, it means that they'll have the same final temperature (T). The heat (q) must be equal for both in magnitude, but with opposite directions.
The heat flows from the higher temperature for the lower, so it flows from the iron (Fe) to the gold (Au) sheet:
qAu = -qFe
The heat can be calculated by the equation:
q = m*cp*ΔT
Where m is the mass, cp is the specif heat capacity, and ΔT the temperature variation.
CpAu = 0.129 J/gºC
CpFe = 0.444 J/gºC
10.2*0.129*(T - 19.4) = -19.9*0.444*(T - 50.8)
1.3158*(T - 19.4) = -8.8356*(T - 50.8)
1.3158T - 25.52652 = -8.8356T + 448.84848
1.3158T + 8.8356T = 448.84848 + 25.52652
10.1514T = 474.375
T = 46.73ºC
Answer: Approximately 3.6 Hydrogen Gas.
Explanation: ...
Sodium(Na) is the limiting reagent.
<h3>What is Limiting reagent?</h3>
The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. The precise quantity of reactant required to react with another element may be estimated from the reaction stoichiometry.
How do you identify a limiting reagent?
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.
Start by writing the balanced chemical equation that describes this reaction
Notice that the reaction consumes 2 moles of sodium metal for every 1 mole of chlorine gas that takes part in the reaction and produces 2 moles of sodium chloride.
now we can see that we have 3 moles of sodium and 3 moles of chlorine, according to question. so, we can say that sodium is the limiting reagent in the given situation.
