Label the molecular view.
aleksley [76]

The elements should be label as follows yellow = OH, blue = Fe, green = Ba, red = Cl

The mix between aqueous barium hydroxide and aqueous iron chloride leads to barium chloride and iron hydroxide. This reaction is shown below:

  • Ba(OH)2 + FeCl3 → BaCl2 + Fe(OH)3

Moreover, in these products, the iron hydroxide will form a solid substance that precipitates in the bottom of the container, while the barium chloride is more likely to maintain its liquid state.

According to this, the substance in the bottom is the iron hydroxide or Fe (OH)2, and in this, the yellow dots represent the Hydroxide or OH, while the blue dots are the Iron considering there in iron hydroxide there are two molecules of OH for each molecule of iron.

On the other hand, at the top, there is the barium chloride or BaCl2. This means the green dots are the Barium and the red ones are the Chlorine as there should be more Chlorine particles than Barium ones

A 73.6 g sample of aluminum is heated to 95.0°C and dropped into 100.0 g of water at 20.0°C. If the resulting temperature of the
Softa [21]

Answer:

The specific heat of aluminium is 0.875 J/g°C

Explanation:

Step 1: Data given

The mass of the aluminium sample = 73.6 grams

Initial temperature of the sample = 95.0 °C

Mass of water = 100.0 grams

Initial temperature of water = 20.0 °C

Final temperature of water and aluminium = 30.0 °C

The specific heat of water = 4.184 J/g°C

Step 2: Calculate the specific heat of aluminium

Q gained = Q lost

Qwater = -Qaluminium

Q =  m*c*ΔT

m(aluminium) * c(aluminium) * ΔT(aluminium) = - m(water) * c(water) * ΔT(aluminium)

⇒ mass of aluminium = 73.6 grams

⇒ c(aluminium) = TO BE DETERMINED

⇒ ΔT(aluminium) = The change of temperature = T2 - T1 = 30 .0 °C - 95.0 °C = -65.0°C

⇒ mass of water = 100.0 grams

⇒ c(water ) = The specific heat of water = 4.184 J/g°C

⇒ ΔT(water) = The change of temperature of water = T2 - T1 = 30.0 - 20.0 = 10.0 °C

73.6g * c(aluminium) * -65.0 °C = 100.0g * 4.184 J/g°C * 10.0°C

-4784 * c(aluminium) = -4184

c(aluminium) = 0.875 J /g°C

The specific heat of aluminium is 0.875 J/g°C

An animal skeleton has a carbon-14 decay rate of 13.1 disintegrations per minute per gram of carbon. When did the animal die? (A
Olenka [21]

Answer:

1034 yrs

Explanation:

The equation to use in this question is:

t = -2.303/k log (A/A₀) where

A=    present number of disintegrations

A₀ =  intial number of disintegrations

k =  decay constant

The decay constant we will obtain it from the given hal-life:

k: 0.693/t₁/₂,        t₁/₂ = half-life   ⇒

k: 0.693 / 5730 y =  1.209 x 10⁻⁴ /y⁻¹

t = - 2.303 / 1.209 x 10⁻⁴ /y⁻¹ x log (13.1/15.3) =  1034 yrs

what type of element can turn into both solid and liquid form depending on the temperature of its surroundings ?​
lorasvet [3.4K]

<em>Answer:</em>

<em>An Atom can turn into both solid and liquid form depending on the temperature of its surroundings </em>

<em>Explanation:</em>

<em>Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously. Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states.</em>
