Decay constant of the process 1×10^(-12) day^(-1).

<h3>What is decay constant?</h3>

A radioactive nuclide's probability of decay per unit time is known as its decay constant, which is expressed in units of s1 or a1. As a result, as shown by the equation dP/P dt =, the number of parent nuclides P declines with time t. Nuclear forces are about 1,000,000 times more powerful than electrical and molecular forces in their ability to bind protons and neutrons. The strength of the bonds holding the radioactive element are likewise indifferent to the decay probabilities and's, in addition to being unaffected by temperature and pressure. The decay constant is related to the nuclide's T 1/2 half-life by T 1/2 = ln 2/.

What is 8(6x+4)=-112

iris [78.8K]

Answer:

x = -3

Explanation:

8(6x + 4) = -112

Divide both sides by 8.

6x + 4 = -14

Subtract 4 from both sides.

6x = -18

Divide both sides by 6.

x = -3

Answer:

HCl(aq) + KOH(aq) —> KCl(aq) + H2O(l)

Explanation:

Aqueous solution of HCl and aqueous solution of KOH react as follow:

HCl(aq) + KOH(aq) —>

In solution, HCl and KOH will dissociates as follow:

HCl —> H+ + Cl-

KOH —> K+ + OH-

During the reaction, a double displacement reaction occur as shown below:

H+ + Cl- + K+ + OH- —> K+Cl- + H+OH-

The elemental equation is given below:

Potassium chlorate decomposes to produce potassium chloride and oxygen gas according to the balanced equation below. If 1.00 g o

aniked [119]

Answer: The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} KClO_3=\frac{1.00g}{122.5g/mol}=0.008moles$

$2KClO_3\rightarrow 2KCl+3O_2$

According to stoichiometry :

2 moles of $KClO_3$ produce= 2 moles of $KCl$

Thus 0.008 moles of $KClO_3$ will produce= $\frac{2}{2}\times 0.008=0.008moles$ of $KCl$

Theoretical yield of $KCl=moles\times {\text {Molar mass}}=0.008moles\times 74.5g/mol=0.596g$

% yield = $\frac{\text {Actual yield}}{\text {Theoretical yield}}\times 100=\frac{0.500g}{0.596g}\times 100\%=83.9\%$

The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%

If 13.4 grams of iron (III) oxide reacts with 12.3 grams of carbon monoxide to produce 8.23 g of pure iron, what are the theoret

Serjik [45]

Theoretical yield is the amount supposedly produced by the reaction if it was complete. The balanced chemical reaction is:

Fe2O3(s) + 3 CO<span>(g) = 2 Fe(s) + 3 </span>CO<span>2(g)
</span>
We use the amounts given for the reactants as the starting point of the calculations. We do as follows:

13.4 g Fe2O3 ( 1 mol / <span>159.69 g ) = 0.08 mol
</span>12.3 g CO ( 1 mol / 28.01 ) = 0.44 mol

Therefore, the limiting reactant would be Fe2O3. We use this for the theoretical yield.

0.08 mol ( 2 mol Fe / 1 mol Fe2O3 ) = 0.16 mol Fe (THEORETICAL YIELD)
8.23 g ( 1 mol / 55.85 g ) = 0.15 mol Fe ( ACTUAL YIELD)

Percent yield = 0.15 / 0.16 x 100 = 93.75%
