Compared to a swimming pool filled with water, a hot cup of coffee has higher temperature, but less thermal energy
Julli [10]
Thermal energy equation is;
    Q = mcΔθ

Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference

the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.

Refer to aqueous solutions containing 1:1 mole ratios of the following pairs of substances. Assume all concentrations are 1 M.
LekaFEV [45]

Answer:

c) HCl and NaCl

Explanation:

Since all the solutions are on a 1:1 mole ratio the comparison is straight forward.

The lowest pH will be for solution c) which has a strong acid, HCl, which ionizes 100 % and the neutral salt NaCl (which is neutral since it is derived from the reaction of the strong acid HCl and the strong base NaOH).

Solutions a) and b) are buffers of  the weak base NH₃ and its conjugate acid NH₄⁺ and weak acid H₃PO₄ and its conjugate weak base NaH₂PO₄ respectively.

Solution c) is a basic solution being a mixture of the weak base NH₃ and the strong base NaOH

Solution e) is a mixture of a weak base NH₂ and weak acid HC₂H₃O₂

Do you know how much water could you get if you started with 250.0 grams of hydrogen?
Soloha48 [4]

The amount of water that could we get if you started with 250.0 grams of hydrogen is 2,250 grams.

<h3>What is moles - mass realation?</h3>

Moles (n) and mass of any substance are related to each other according to the given equation as:

n = W/M, where

W = given mass

M = molar mass

Given balanced chemical reaction is:

2H₂ + O₂ → 2H₂O

Moles of 250g of H₂ = 250g / 2g/mol = 125mol

From the stoichiometry of the reaction it is clear that,

2 moles of H₂ = produces 2 moles of H₂O

125 moles of H₂ = produces 125 moles of H₂O

Now mass of water will be calculated as:

Mass = (125mol)(18g/mol) = 2,250g

Hence required mass of water is 2,250 grams.
