Answer:

Watts

Explanation:

Work done of an object is given by the product of force and displacement i.e.

W = F.d

Where

F = force

d = displacement

The SI unit of work done is joules. It is defined as the amount of energy used or exerted when a force of 1 newton is applied over a distance of 1 meter.

Power output is defined as "work done per unit time". Mathematically, it is given by :

P=\dfrac{W}{t}

The SI unit of power is watts. It is defined as the "amount of energy used when 1 joule of work is done per unit time".

Hence, power is measured in watts.

How many sulfur atoms are present in 25.6 g of Al2(S2O3)3
IgorC [24]

Given the mass of Al_{2}(S_{2}O_{3})_{3}=25.6 g

The molar mass of Al_{2}(S_{2}O_{3})_{3}=390.35g/mol

Converting mass of Al_{2}(S_{2}O_{3})_{3}to moles:

25.6 g Al_{2}(S_{2}O_{3})_{3}*\frac{1molAl_{2}(S_{2}O_{3}}{390.35 gAl_{2}(S_{2}O_{3}} =0.0656molAl_{2}(S_{2}O_{3}

Converting mol Al_{2}(S_{2}O_{3})_{3}to mol S:

0.0656mol Al_{2}(S_{2}O_{3})_{3}*\frac{6molS}{1mol Al_{2}(S_{2}O_{3})_{3}}=0.3936 molS

Converting mol S to atoms of S using Avogadro's number:

1 mol = 6.022*10^{23}atoms

0.3936mol S *\frac{6.022*10^{23}atoms S}{1 mol S}=2.37*10^{23} S atoms

Writing a pressure equilibrium constant expression Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4 NH
Sliva [168]

<u>Answer:</u> The equilibrium constant expression for the given equation is written below.

<u>Explanation:</u>

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{p}

For the general chemical equation:

aA+bB\rightleftharpoons cC+dD

The expression of K_p follows:

K_p=\frac{p_C^c\times p_D^d}{p_A^a\times p_B^b}

For the given chemical equation:

4NH_3(g)+5O_2(g)\rightleftharpoons 4NO(g)+6H_2O(g)

The expression of K_p for above equation follows:

K_p=\frac{(p_{H_2O}^5)\times (p_{NO}^4)}{(p_{NH_3}^4)\times (p_{O_2}^5)}

Hence, the equilibrium constant expression for the given equation is written above.
