First you find out how much each element has

Fe=1 * 2 Fe=1
Cl=2 *3 Cl=3 *2

now we multiply each so we can balance each side.

So now we get our balanced equation
2 Fe + 3 Cl2 = 2 FeCl<span>3</span>

Plutonium-236 is an alpha emitter with a half-life of 2.86 years. how long will it take for the 1.10 mg sample of pu−236 to deca

lawyer [7]

1.1 / 2 = .7 --> 2.86 yrs

.7 / 2 = .45 —> 5.72 yrs

.45 / 2 = .225 —> 8.58 yrs

.225 / 2 = .1125 —> 11.44 yrs

So, for the sample of plutonium to reach .140 mg it should take a little less than 11.44 years.

Hope this helps

Consider the reaction.

vovangra [49]

Answer: The value of Keq for the reaction expressed in scientific notation is $1.6\times 10^{-5}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

For the given chemical reaction:

$2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)$

The expression for $K_{eq}$ is written as:

$K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}$

$K_{eq}=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}$

$K_{eq}=1.6\times 10^{-5}$

The value of Keq for the reaction expressed in scientific notation is $1.6\times 10^{-5}$

What unit is used for atomic mass

kicyunya [14]

Answer:

universal mass unit

<h2 />

The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
