One isotope of bromine has an atomic mass of 78.92amu and a relative abundance of 50.69%. The other major isotope of bromine has

castortr0y [4]

Answer:

The average atomic mass is 79.91 amu.

Explanation:

Since

Atomic mass can be find by Multiplying the relative abundance of each isotope by its atomic mass, then add them together to get the atomic mass of the element.

Atomic mass = (0.5069)(78.92 amu) + (0.4931)(80.92 amu)

=79.91 amu

So the Atomic mass of the bromine is 79.91amu.

Based on the replacement reaction, what would the products of the reaction be?

fredd [130]

Answer:

Explanation:

BeSO₄ + 2NH₄OH → Be(OH)₂ + (NH₄)₂SO₄

In a replacement reaction, an atom or ion substitutes or replaces another in a reaction. We can have single replacement or double replacement reaction.

The above is a double replacement reaction. In this type of reaction, partners are exchanged to form compounds. In a single replacement, one substance is replacing another.

In the lab, you submerge 100 g of 40°C nails in 200 g of 20°C water. (The specific heat of iron is 0.12 cal/g # °C.) Equate the

Deffense [45]

Answer:

Final temperature of the mixture becomes

$T = 21.13^oC$

Explanation:

Here we know that heat given by the nail is equal to the heat absorbed by water

So here we know that heat to change the temperature is given as

$Q = ms\Delta T$

so by equating the heat we have

$m_{iron}s_{iron}\Delta T = m_{water}s_{water}\Delta T$

now we have

$100 (0.12) (40 - T) = 200 (1) (T - 20)$

$4.8 - 0.12 T = 2T - 40$

$44.8 = 2.12 T$

$T = 21.13^oC$

Si se tiene un gato hidráulico y se aplica una fuerza en el Area 1, se refleja otra fuerza en el Area 2, teniendo en cuenta la s

iren [92.7K]

Answer:

the forces are proportional to their areas of application

Explanation:

In a hydraulic jack, Pascal's principle is used, that the pressure in an incompressible liquid is the same at the same height, whereby the pressure on both sides of the jack are the same

P₁ = P₂

the pressure is defined by

P = F / A

we substitute

$\frac{F_1}{A_1} = \frac{F_2}{A_2}$

F₂ = $\frac{A_2}{A_1} \ F_1$

therefore the force is F₂> F₁

Therefore the forces are proportional to their areas of application
