Answer: a. They produce ions when dissolved in water.

Explanation:

Acid : It is a substance that has ability of donating proton or hydrogen ion, H^+ when dissolved in water.

Acids are sour in taste.

The texture of an acid solution is sticky.

It changes the color of the litmus paper to red.

Base : It is a substance that has ability of donating hydroxide ion, OH^- when dissolved in water.

Base are bitter in taste.

The texture of an base solution is slippery.

It changes the color of the litmus paper to blue.

Thus both acids and bases produce ions when dissolved in water.

According to collision theory, the rate of reaction depends on atoms colliding in the correct _________ with enough ________ for
kenny6666 [7]

Answer: orientation , energy , frequency

Explanation:

According to the collision theory , the number of collisions that take place per unit volume of the reaction mixture is called collision frequency. The effective collisions are ones which result into the formation of products.

Effective collisions depends on the following  two factors:-

1. Orientation factor: The colliding molecules must have proper orientation at the time of collision to result into formation of products.

2. Energy factor:  For collision to be effective,  the colliding molecules must have energy more than a particular value called as threshold energy.

Necesito saber esto porfavor, ¿ cuales son las ventajas que representan los espectroscopia en cuanto al estudio de los elementos
igomit [66]

Answer:

Por favor,no ponga exactamente lo que pongo,Trate de parafrasear.

La espectroscopia es el estudio de la interacción entre la materia y la radiación electromagnética en función de la longitud de onda o frecuencia de la radiación. La espectroscopia puede ser muy útil para ayudar a los científicos a comprender cómo un objeto como un agujero negro, una estrella de neutrones o una galaxia activa produce luz, qué tan rápido se mueve y de qué elementos está compuesto. Se pueden producir espectros para cualquier energía de la luz, desde ondas de radio de baja energía hasta rayos gamma de muy alta energía.

We can use two equations for this problem.<span>

t1/2 = ln 2 / λ = 0.693 / λ
Where t1/2 is the half-life of the element and λ is decay constant.

20 days = 0.693 / λ 
λ   = 0.693 / 20 days        (1) 

Nt = Nο eΛ(-λt)                (2)

Where Nt is atoms at t time, No is the initial amount of substance, λ is decay constant and t is the time taken.
t = 40 days</span>

<span>No = 200 g

From (1) and (2),
Nt =  200 g eΛ(-(0.693 / 20 days) 40 days)
<span>Nt = 50.01 g</span></span><span>

</span>Hence, 50.01 grams of isotope will remain after 40 days.
