Answer:

m_{solution}=470g

Explanation:

Hello,

In this case, a solution is formed when a solute is completely dissolved in a solvent, thus, for this situation, the sugar is the solute and the water the solvent but in addition to them we find spices which are also considered in the total mass of the solution. In such a way, for computing the total mass we must add the mass of three constituents (115 g sugar, 350 g water and 5 g spices) as shown below:

m_{solution}=115g+350g+5g\\\\m_{solution}=470g

Best regards.

What is the key difference between organic and inorganic molecules​
Naya [18.7K]

Answer:

See the answer below, please.

Explanation:

Organic compounds are those produced by living beings (molecules associated with living beings) and correspond to carbon compounds (the main difference with inorganic compounds). The latter are produced by natural processes or in the laboratory.

Example of organic products: alkanes (methane), alcohols (ethanol or ethyl alcohol)

Example of inorganic products: sodium hydroxide, sodium chloride

5. What is the final "Celsius" temperature if 2.40 L of gas at 30.5 C is cooled until the volume reaches 1.00 L at constant pres
slega [8]

Answer:

Final temperature of the gas = -146.63 °C

Explanation:

At constant pressure, volume and temperature of the gases are related as:

\frac{V_1}{T_1}=\frac{V_2}{T_2}

Where,

V1 = Initial volume = 1.00 L

V2 = Final volume = 2.40 L

T1 = Initial temperature = 30.5 °C = 30.5 + 273.15 = 303.65 K

Now, substitute the values in the above equation,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

\frac{2.40\;L}{303.65}=\frac{1.00\;L}{T_2}

T_2=\frac{1.00\times 303.65}{2.40}

T2 = 126.52 K

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

T( °C) = T(K) - 273.15

          = 126.52 - 273.15 = -146.63 °C

what volume (ml) of 3.0M NaOH is required to react with 0.8024-g copper ii nitrate?what mass of copper ii hydroxide will form as
Ksivusya [100]

The reaction between NaOH and Cu(NO₃)₂ is as follows

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂


Q1) stoichiometry of NaOH to Cu(NO₃)₂ is 2:1

this means that 2 mol of NaOH reacts with 1 mol of Cu(NO₃)₂

the mass of Cu(NO₃)₂ reacted - 0.8024 g 

molar mass of Cu(NO₃)₂ is 187.56 g/mol

therefore the number of Cu(NO₃)₂ moles that have reacted

 - 0.8024 g/ 187.56 g/mol = 0.00427 mol

according to the stoichiometry , number of NaOH moles - 0.00427 mol x 2 

then number of NaOH moles that have reacted - 0.00855 mol

In a 3.0 M NaOH solution, 3 moles are in 1000 mL of solution

Then volume required for 0.00855 mol - 1000 x 0.00855 /3 = 2.85 mL

2.85 mL of 3.0 M NaOH is required for this reaction


Q2) Assuming that there's 100 % yield of Cu(OH)₂ , we can directly calculate the mass of Cu(OH)₂ formed from the number of moles of reactants that were used up. 

Stoichiometry of Cu(NO₃)₂ to Cu(OH)₂ is 1:1

this means that 1 mole of Cu(NO₃)₂ gives a yield of  1 mole of Cu(OH)₂

the number of Cu(NO₃)₂ moles that reacted - 0.00427 mole 

Therefore an equal amount of moles of Cu(OH)₂ were formed

Then amount of Cu(OH)₂ moles produced - 0.00427 mol

Mass of Cu(OH)₂ formed - 0.00427 mol x 97.56 g/mol = 0.42 g 

A mass of 0.42 g of Cu(OH)₂ was formed in this reaction.

A polyatomic ion is a cluster of covalently-bonded atoms with a _____ that acts as a unit.
yKpoI14uk [10]

Positive or negative charge

A polyatomic ion is a cluster of covalently bonded atoms with a positive or negative charge that acts as a unit.

A polyatomic ion is a covalently bonded groups of atoms that acts as a single unit and has a positive or negative charge as a result of the formation of an ionic bond with another ion. An example of a polyatomic ion is hydroxide ion which has the chemical formula; OH− (has a charge of −1), and is made up of one oxygen atom and one hydrogen atom.
