Write the balanced COMPLETE ionic equation for the reaction when aqueous NiCl₂ and aqueous Na₂S are mixed in solution to form so

Reptile [31]

Answer:

Explanation:

The chemical reaction of the well-balanced equation is as follows:

$\mathbf{2NiCl_{2(aq)}+2Na_2S_{(aq)} \to 4NaCl_{(aq)}+2NiS_{s}}$

The aforementioned reaction's ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+4Cl^-_{(aq)}+ 4Na^+_{(aq)}+2S^{2-}_{(aq)} \to 4Na^+_{(aq)}+4Cl^-_{(aq)}+2NiS_{(s)}}$

From above; Na⁺ and Cl⁻ appear on both sides;

Hence, the net ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+2S^{2-}_{(aq)} \to 2NiS_{(s)}}$

After decaying for 48 hours, one-sixteenth (1/16) of the original mass of a radioisotope sample remains unchanged. What is the h

Hunter-Best [27]

The half-life of this radioisotope : 12 hr

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.

Usually radioactive elements have an unstable atomic nucleus.

General formulas used in decay:

$\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}$

t = duration of decay

t 1/2 = half-life

N₀ = the number of initial radioactive atoms

Nt = the number of radioactive atoms left after decaying during T time

t=48 hr

$\tt \dfrac{Nt}{No}=\dfrac{1}{16}$

The half-life :

$\tt \dfrac{1}{16}=\dfrac{1}{2}^{(48/t\frac{1}{2} )}\\\\(\dfrac{1}{2})^4=(\dfrac{1}{2})^{48/t\frac{1}{2}}\\\\4=48/t\frac{1}{2}\\\\t\frac{1}{2}=12~hr$

HELP! I NEED THIS ANSWERED ASAP!!!

stealth61 [152]

Answer:

The rate of reaction will maintain constant

Explanation:

Rate of reaction is proportionate to rate constant x [A] ^2 x [B]. This means that the order of reaction with respect to C is 0 as it does not affect the rate of reaction as seen in the rate equation.

Essentially, order of reaction with respect to C is [C] ^0

Hence if [C] triples and becomes [3C]^0, the result will still be 1 as anything to the power of 0 is 1.

Therefore, the answer is that the rate of reaction will remain constant.
