Answer:

$\lambda = \frac{c}{\nu}$

Explanation:

The wavelenght of a radiation is inversely proportional to its frequency. It can be estimated by the following formula:

$\lambda = \frac{c}{\nu}$

Where:

$\lambda$ is the wavelenght
$\nu$ is the frequency
$c$ is the speed of light (arroung 300000 km/s)

Answer:

(a) Barium is produced at the negative electrode

(b) Iodine is produced at the positive electrode

Explanation:

When an electric current is passed through a solution containing electrolyte, a non spontaneous reaction is stimulated. This results in the flow of positively charged ions to negatively charged electrodes(cathode) and negatively charged ions to positively charged electrodes(anode)

When an electric current is passed through molten $BaI_{2}$ in the electrolytic cell, the following reactions takes place:

$BaI_{2}$ → $Ba^{2+}$ + 2 $I^{-}$

At the anode;

Iodine ions will lose an electron and will be oxidized to iodine

$2I^{-}$ → $I_{2}$ + $e^{-}$

At the cathode;

Barium ions gains electrons and its reduced to barium metal

$Ba^{2+}$ + $2e^{-}$ → Ba

PLEASE HELP this is physical science.

Bone age : 22,920 years

<h3>Further explanation</h3>

Given

Nt = 2.5 g C-14

No = 40 g

half-life = 5730 years

Required

time of decay

Solution

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

Input the value :

$\tt 2.5=40.\dfrac{1}{2}^{t/5730}\\\\\dfrac{2.5}{40}=\dfrac{1}{2}^{t/5730}\\\\(\dfrac{1}{2})^4=\dfrac{1}{2}^{t/5730}\\\\4=t/5730\rightarrow t=22920~years$

How do I explain this? I'm a little stuck. :/

Dimas [21]

Answer:

Not balance.

Explanation:

Chemical equation:

K + Cl₂ → KCl

The given equation is not balance because there are one potassium and two chlorine atoms on left side of equation while on right side there are one potassium and one chlorine atom present.

Balance chemical equation:

2K + Cl₂ → 2KCl

the equation is balance now because there are two potassium and two chlorine atoms on left side of equation and two potassium and two chlorine atoms are also present on right side.
