Rhodium-101 has a half life of 3.3 years. What percent of the sample will remain after 6.6 years?

Chemistry

babunello [35]2 years ago
5 0

Answer:

25%

Explanation:

Half life means that 50% of the sample is gone at 3.3 years. This means that an additional 3.3 years (total 6.6 years) will reduce the sample a further 50% from the point at 3.3 years. In numbers, this means 50% of 50% (0.50*0.50), which is 25%.

Uno de los componentes del “sal de uvas”, es el bicarbonato de sodio, es un sólido cristalino blanco, debido a su capacidad de neutralizar el exceso de ácido clorhídrico del estómago.

La acidez estomacal es ocasionada por un exceso en la producción de ácido clorhídrico (HCl) en el jugo gástrico del estómago. Uno de los componentes del “sal de uvas”, utilizada como antiácido, es el bicarbonato de sodio (NaHCO₃), es un sólido cristalino blanco, que neutraliza el exceso de ácido clorhídrico. La reacción de neutralización es:

HCl(aq) + NaHCO₃(aq) ⇒ NaCl(aq) + H₂O(l) + CO₂(g)

Uno de los componentes del “sal de uvas”, es el bicarbonato de sodio, es un sólido cristalino blanco, debido a su capacidad de neutralizar el exceso de ácido clorhídrico del estómago.

The chemical equation below shows the decomposition of nitrogen triiodide (NI3) into nitrogen (N2) and iodine (I2). 2NI3 Right a
yuradex [85]

The moles of I₂ will form from the decomposition of 3.58g of NI₃ is 0.0136 moles.

<h3>How we calculate moles?</h3>

Moles of any substance will be calculated as:

n = W/M, where

W = required mass

M = molar mass

Given chemical reaction is:

2NI₃ → N₂ + 3I₂

Moles of 3.58g of NI₃ will be calculated as:

n = 3.58g / 394. 71 g/mol = 0.009 moles

From the stoichiometry of the solution, it is clear that:

2 moles of NI₃ = produce 3 moles of I₂

0.009 moles of NI₃ = produce 3/2×0.009=0.0136 moles of I₂

Hence, option (3) is correct i.e. 0.0136 moles.
