How many particles are in one mole of copper (II) sulfate, CuSO4?

The given reaction is the type of Decomposition reaction. A decomposition reaction occurs when one reactant splits into many products.

Chemistry reaction reactions of decomposition. Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.

Decomposition reactions are those that divide or break the compounds into two simpler products. Because two or more reactants are combined to create a single product in a combination reaction, they are known as the reverse of combination reactions.

It entails the severing of ties. Energy is necessary to dismantle the bonding between atoms. Decomposition advances when energy in the form of heat or electricity is provided. As the bond is broken during this reaction, energy is given to them, making them endothermic processes.

Answer:

Overpopulated prey.

Explanation:

Because if you remove the predators from the picture who's gonna eat the prey? So it would only make sense that the prey would overpopulate! Hope this helped! (^-^)

A removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

An ecosystem, sometimes known as just an ecological system, primarily made up of all the species that dwell in the physical environment. These abiotic components are linked via nutrition cycles as well as energy fluxes.

Animals contribute significantly to the transport of nutrients as well as energy through the system by consuming plants and each other. They also influence the biomass concentrations of microbial and plant populations. A removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

Therefore, a removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

Answer:

The final temperature of both substances at thermal equilibrium is 17.3°C

Explanation:

To calculate the final temperature of both substances at thermal equilibrium -:

First , we calculate the heat of A1  cube as follows -

            q= mSΔT

(where q = heat of the cube , m = mass of cube , S= specific heat of cube  {0.902j/g°C}, T = Temperature )

Putting the values given in the question ,

        [tex]q= 32.5g\times0.902\j/g[/tex]°[tex]C[/tex][tex]\times(T_f-45.8[/tex]°[tex]C)[/tex]

            [tex]29.315\times(T_f-45.8)J[/tex]

Now , calculate the heat of water -

         q=mSΔT

Putting values from the question ,

           [tex]q=105.3g\times4.18j/g[/tex]°[tex]C[/tex][tex]\times (T_f-15.4[/tex]°[tex]C)[/tex]

              =[tex]440.154\times(T_f-15.4)J[/tex]

          Now ,

Heat lost by water A1= Heat gained by water [negative sign about heat lost]

         [tex]-29.315\times(T_f-45.8)J[/tex] [tex]=440.154\times(T_f-15.4)J[/tex]

            [tex]\frac{-(T_f-45.8)J}{T_f-15.4)J} =\frac{440.154}{29.315}=15.0[/tex]

      [tex]-T_f+45.8[/tex]°[tex]C=15T_f-231.2[/tex]°[tex]C[/tex]

       [tex](45.8+231.2)[/tex]°[tex]C[/tex]=[tex]16T_f[/tex]

        [tex]16T_f=277.03[/tex]°[tex]C[/tex]

       [tex]T_f=\frac{277.03}{16}[/tex] = 17.3°C

Therefore , the final temperature of both substances at thermal equilibrium is 17.3°C

Answer: 11.8 grams of [tex]CaCl_2[/tex] is required.

Explanation:

To calculate the number of moles for given molarity, we use the equation:

[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in L)}}[/tex]     .....(1)

Molarity of [tex]AgNO_3[/tex] solution = 0.506 M

Volume of solution = 420 mL

Putting values in equation 1, we get:

[tex]0.506M=\frac{\text{Moles of} AgNO_3\times 1000}{420ml}\\\\\text{Moles of }AgNO_3=\frac{0.506mol/L\times 420}{1000}=0.212mol[/tex]

The balanced chemical reaction is:

[tex]2AgNO_3+CaCl_2\rightarrow 2AgCl+Ca(NO_3)_2[/tex]

2 mole of [tex]AgNO_3[/tex] requires = 1 mole of [tex]CaCl_2[/tex]  

0.212 moles of [tex]AgNO_3[/tex] require = [tex]\frac{1}{2}\times 0.212=0.106[/tex] moles of [tex]CaCl_2[/tex]

Mass of  [tex]CaCl_2[/tex] =[tex]moles\times {\text {Molar Mass}}=0.106mol\times 111g/mol=11.8g[/tex]

Answer:

Answer:

[Zn(C₂H₃O₂)₂] = 1.85M (3 sig-figs accurate to 0.01 Molar)

Explanation:

Concentration is defined as amount of solute in a specified volume of solution. That is, Concentration = mass of solute/volume of solution (solution = solute + solvent). When concentration is in terms of Molar values the essential relationship is Molarity(M) = moles solute / volume of solution in liters.

For this problem => first, convert mass of Zn(C₂H₃O₂)₂ into moles and then the volume of solution into liters. Take ratio of moles/volume of solution (L).

=> Molar Concentration = moles of Zn(C₂H₃O₂)₂ / Liters of solution

moles of Zn(C₂H₃O₂)₂ = 85.0 grams Zn(C₂H₃O₂)₂ / formula weight of Zn(C₂H₃O₂)₂  =  85.0g/183.5g·mole⁻¹ = 0.463 mole Zn(C₂H₃O₂)₂.

Volume of solution in Liters = 250ml / 1000ml/L = 0.250 liters

Molarity of  Zn(C₂H₃O₂)₂ solution = 0.463 mole Zn(C₂H₃O₂)₂  /0.250 liters of solution = 1.85 Molar in Zn(C₂H₃O₂)₂

_____________

Note: The symbiology convention for 'molar solution concentration' is to place brackets around the molecular formula. That is, [Zn(C₂H₃O₂)₂] = 1.85M

Answer:

[tex]\boxed {\boxed {\sf A. \ SiCl_4}}[/tex]

Explanation:

We are given the compound name: silicon tetrachloride.

Silicon is a metalloid and chlorine is a nonmetal, therefore we must use the rules of molecular compounds. Molecular compounds use prefixes to name the compounds. Break up the compound into 2 parts.

1. Silicon

The first element: silicon, has no prefix. Therefore, a prefix of mono (1) is implied.

2. Tetrachloride

The -ide suffix is added to the second element, so this is really chlorine. The prefix of tetra means 4.

So there is 1 silicon (Si) atom and 4 chlorine (Cl) atoms. The formula must be SiCl₄

20.8L = Final volume of the gas

Explanation:

Based on Charles's law, the volume of a gas is directly proportional to the temperature of the gas under pressure constant. The equation is:

[tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

where V is volume and T absolute temperature of 1, initial state and 2, final state.

If initial volume is 22.5L, initial T = 365K and final temperature 338K:

22.5L / 365K = V₂ / 338K
