Answer:

Estos elementos se denominan metales de transición, metales pesados, elementos del bloque D, etc.

Explanation:

Aquí, en esta pregunta, queremos saber la razón por la cual hay un espacio de 10 elementos entre el calcio, que es un elemento del grupo dos, y el galio, que es un elemento del grupo 3.

Al observar la tabla periódica, la tabla periódica moderna, notamos un bloque de elementos entre los elementos del grupo 2 y los elementos del grupo 3 en la tabla periódica.

Entonces, ¿por qué se colocan estos elementos entre ambos grupos? Se colocan aquí porque no pertenecen en su totalidad al grupo 2, ni tampoco al grupo 3.

Estos elementos presentan una especie de estados de oxidación variables que son responsables de una amplia variedad de propiedades comunes entre ellos.

Answer:

1.6cm3

Explanation:

density = mass/volume

15.6g/cm3= 9.75 g/volume

15.6/9.75 = volume

1.6cm3 = volume

Answer:

A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density? Step 1: Calculate the volume. V = lwh = 10.0 ...

Missing: Dam/ ‎43.0

Answer:

2.48 g

Explanation:

From the question given above, the following data were obtained:

Original amount (N₀) = 10 g

Time (t) = 1407.6 million years

Amount remaining (N) =?

Next, we shall determine the rate of decay (K) of uranium-235. This can be obtained as follow:

NOTE: Uranium-235 has a half life of 700 million years.

Decay constant (K) =?

Half life (t½) = 700 million years

K = 0.693/t½

K = 0.693/700

K = 9.9×10¯⁴ / year

Therefore, Uranium-235 decay at a rate of 9.9×10¯⁴ / year.

Finally, we shall determine the amount of Uranium-235 remaining after 1407.6 million years as follow:

Original amount (N₀) = 10 g

Time (t) = 1407.6 million years

Decay constant (K) = 9.9×10¯⁴ / year

Amount remaining (N) =?

Log (N₀/N) = kt /2.3

Log (10/N) = (9.9×10¯⁴ × 1407.6) /2.3

Log (10/N) = 0.60588

10/N = antilog (0.60588)

10/N = 4.04

Cross multiply

10 = 4.04 × N

Divide both side by 4.04

N = 10/4.04

N = 2.48 g

Therefore, 2.48 g of uranium-235 is remaining after 1407.6 million years.

If you have a 10 gram sample of uranium-235 there would still be uranium-235 after 1407.6 million years - 2.5 grams.

The half-life of U-235 is the time it takes for half the U to decay. We know that U-235 has 703.8 million years as its half-life which means it takes 703.8 million years to half of its initial amount.

We can construct a table as follows:    

No. of                              Fraction        Amount    

half-lives    t/(yr × 10⁶)     remaining    remaining/g    

   1                703.8              ½              10/2 = 5  

   2              1407.6              ¼              10/4 =  2.50    

Thus, the correct answer is - 2.5 grams.

Answer:

intermolecular bonding

Explanation:

Answer:

0.56 kg

Explanation:

F = ma. Force = Mass x acceleration

Let's take a look at why that works. If something has more mass ie atoms then it will require more effort to move it. If you want make something speed up at a higher rate then again you need to provide more of an effort. Therefore you need more force for both these situations.

Therefore the equation works.

Answer:

gravity

Explanation: its a force that pulls you down but you are never making contact with it

Answer: Gravity

Explanation:

It pushes you down but you never actually touch it
