HELP!! Suppose that the pressure of 1.00 L of gas is 380 mm Hg when the temperature is 200. K. At what
Korolek [52]
Numa máquina térmica uma parte da energia térmica fornecida ao sistema(Q1) é transformada em trabalho mecânico (τ) e o restante (Q2) é dissipado, perdido para o ambiente.



sendo:

τ: trabalho realizado (J) [Joule]
Q1: energia fornecida (J)
Q2: energia dissipada (J)


temos: τ = Q1 - Q2

O rendimento (η) é a razão do trabalho realizado pela energia fornecida:

η= τ/Q1

Exercícior resolvido:
Uma máquina térmica cíclica recebe 5000 J de calor de uma fonte quente e realiza trabalho de 3500 J. Calcule o rendimento dessa máquina térmica.

solução:

τ=3500 J
Q1=5000J

η= τ/Q1
η= 3500/5000
η= 0,7 ou seja 70%

Energia dissipada será:



τ = Q1 - Q2
Q2 = Q1- τ

Q2=5000-3500
Q2= 1500 J

Exercicio: Qual seria o rendimento se a máquina do exercicio anterior realizasse 4000J de trabalho com a mesma quantidade de calor fornecida ? Quanta energia seria dissipada agora?

What would be the interactions between side chains of aspartate and arginine at a neutral ph?
weeeeeb [17]

The answer is asparagine interactions between aspartate and arginine side chains at neutral pH

<h3>What side chain does arginine have?</h3>
  • The amino acid arginine has the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.
  • A guanidino group is attached to a typical amino acid framework in the molecule.
  • The carboxylic acid is deprotonated (CO2) and both the amino and guanidino groups are protonated, resulting in a cation at physiological pH.
  •  The guanidine group in arginine is the precursor for nitric oxide production. it is a white, water-soluble solid, like all amino acids.

What mass of oxygen reacts with 4.62 g of magnesium to form magnesium oxide according to the following... 2 Mg O2 --&gt; MgO
Goryan [66]

Answer:

3.08 g of Oxygen .

Explanation:

2Mg      + O₂     =     2MgO

2 mole  1 mole

molecular weight of Mg = 24

2 mol of Mg = 48 g

48 g of Mg reacts with 32 g of oxygen

4.62 g of Mg will reacts with 3.08 g of Oxygen .
