What is the fixer solution equation?
Answer:
Fixation involves these chemical reactions (X = halide, typically Br−): AgX + 2 S2O32− → [Ag(S2O3)2]3− + X. AgX + 3 S2O32− → [Ag(S2O3)3]5− + X. In addition to thiosulphate the fixer typically contains mildly acidic compounds to adjust the pH and suppress trace amounts of the developer.

Give three examples of energy traveling in waves
Answer:
ELECTROMAGNETIC SPECTRUM. Radios, televisions, mobile phones, and radar use signals made up of electromagnetic waves. These are waves that carry energy as electricity and magnetism at the speed of light. Light we can see is also an electromagnetic wave, but other types of electromagnetic wave are invisible.

23. Which of the following solutions will reach dynamic equilibrium?
a Supersaturated solution
b Unsaturated solution
C Saturated solution
d None of the above
Answer:
C
Explanation:
The solution that will reach dynamic equilibrium is a saturated solution. The correct option is C.
What is an unsaturated solution?A chemical solution in which the solute concentration is less than its equilibrium solubility is known as an unsaturated solution.
The solvent dissolves the entire solute.
When a solute (typically a solid) is mixed with a solvent (commonly a liquid), two reactions take place at the same time.
Thus, the correct option is C, the saturated solution.

What mass of potassium would need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C? (cpotassium = 0.753 J/g°C)
Answer:
Explanation:
q = mCΔT
m =CΔT/q
ΔT = 57.8°C - 44.3°C = 13.5°C
m = (0.753*13.5)/2350
m = 0.00433 g
The mass of potassium that will need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C is 231.17 g
Data obtained from the question Heat (Q) = 2350 JInitial temperature (T₁) = 44.3 °CFinal temperature of water (T₂) = 57.8 °CChange in temperature (ΔT) = 57.8 – 44.3 = 13.5 °C Specific heat capacity (C) = 0.753 J/gºC Mass (M) =?Q = MCΔT
2350 = M × 0.753 × 13.5
2350 = M × 10.1655
Divide both side by 10.1655
M = 2350 / 10.1655
M = 231.17 g

Answer:
C. So electrons can flow from one electrode to another
Explanation:
An electrochemical cell is any cell in which electricity is produced by reason of a chemical change.
An electrochemical cell consists of two electrodes, these two electrodes are connected using a wire.
Usually, electrons flow from one electrode to another via this wire thereby enabling the electrochemical processes of oxidation and reduction in the cell to proceed effectively.
A radioisotope has a half-life of 5 minutes. What fraction of material would remain after
half an hour?
Which correctly lists the 3 types of
radiation from least damaging to most
damaging?
alpha < beta < gamma
alpha < gamma < beta
gamma < beta < alpha
beta < gamma < alpha
Answer:
alpha < beta < gamma.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Generally, all radioactive elements are capable of emitting radiation. The three (3) types of nuclear radiation from least damaging to most damaging are; alpha, beta and gamma.
This ultimately implies that, alpha particles have the least damaging (penetrative) ability followed by beta particles and lastly, gamma rays.

Deforestation is the act of destroying forests so the land can be used for other purposes. Do you think deforestation increases, decreases, or has no effect on the biodiversity of the forest ecosystem? Explain your answer.
Answer:
deforestation decreases biodiversity of the forest ecosystem
Explanation:
Deforestation has to do with the process of felling trees. This process destroys forest ecosystems. Deforestation is normally carried out for the purpose of development.
An ecosystem is a self supporting unit in which living and non living things interact. The different species of plants and animals found in an ecosystem is called biodiversity.
Since organisms in an ecosystem interact among each other and with their non-living environment, destruction of the trees in the forest ecosystem leads to the loss of certain species present in the ecosystem.
For instance, climbers and animals found on tree tops are normal components of a forest ecosystem. When trees are felled and the forest ecosystem is destroyed across the world, these organisms are threatened. This leads to loss of species or loss of biodiversity.
Answer:
Here’s one possible answer:
Deforestation will likely decrease the biodiversity of the forest ecosystem. It reduces the living space and food sources for some of the organisms. Scarcity of space and food may be a threat to the population of those organisms. Over time, some species may die off, leaving fewer species in the forest.

Al hacer reaccionar 5g de cinc con ácido sulfúrico se observa que la reacción ocurre en 20s. ¿Cuál será la rapidez de la reacción? Masa atómica del cinc 65,37g.
Answer:
0.0038 mole s-1
Explanation:
La velocidad de una reacción se refiere a la rapidez o la lentitud con que avanza una reacción. Se mide por la cantidad de reactivos que desaparecen por unidad de tiempo o por la cantidad de productos que aparecen por unidad de tiempo.
Número de moles de zinc = 5g / 65.37gmol-1 = 0.076 moles
Velocidad de reacción = 0.076 moles - 0 moles / 20 s - 0s = 0.0038 mole s-1

26.3 mol
46.7 mol
23.3 mol
10.0 mol
Answer:
26.3 mol O₂
Explanation:
Step 1: Write the balanced equation
4 FeCl₃ + 3 O₂ ⇒ 2 Fe₂O₃ + 6 Cl₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of FeCl₃ to O₂ is 4:3.
Step 3: Calculate how many moles of O₂ are needed to react completely with 35.0 mol of FeCl₃
We will use the previously established molar ratio.
35.0 mol FeCl₃ × 3 mol O₂/4 mol FeCl₃ = 26.3 mol O₂

How would the number of atoms in a 2.02g sample of hydrogen compare to the number of atoms in a 32.00g sample of oxygen
Answer:
Number of atoms is equal.
Explanation:
1 mol of anything contains NA particles.
NA is known as Avogadro's number, 6.02×10²³
We determined the moles of each compound. Both molecules are dyatomic,
H₂ → 2.02 g . 1mol / 2.016 g = 1 mol
O₂ → 32 g . 1mol / 32g = 1 mol
Both have the same amount of moles.
In conclussion, the number of atoms is the same in both samples.
