The next missing ingredient or element here is nitrogen. The next possible answers would be phosphorus and sulfur, respectively in their average concentration in living things.

There are many reasons why nitrogen is necessary. One importance is that nitrogen is one of the components of amino acids. Amino acids are the units needed to make proteins. And proteins is pretty much what makes up all living things.

Solid aluminum hydroxide reacts with a solution of hydrobromic acid. write a balanced molecular equation and a balanced net ioni
Stolb23 [73]
<span>To find the balanced molecular equation, we need to find the symbols for each element and their charges and then balanced the equation. This comes out to: Al(OH)3(aq) + 3HBR(aq) ---> AlBr3(aq) + 3H2O(l) The net ionic equation is adding the charges and separating them into basic components. Al3+ + 3OH- + 3H+ + 3BR- --> Al3+ + 3Br + H3O+ We can cancel out the aluminum and bromine to get: 3OH-(aq) + 3H+(aq) --> 3H2O(l)</span>

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?
