Answer: 4.6 M

Explanation:

Converting 25 g of HCl to moles, we get 25/36.46 = 0.68568294020845 moles.

Also, 150 mL = 0.150 L

So, the concentration is:

[tex]\frac{0.68568294020845}{0.150} =\boxed{4.6 \text{ M}}[/tex]

Answer:  

Part 1.  First, you find the Moles.

Part 2. The correct setup for finding the moles is: 25g  HCI x 1mol HCI/36.46g HCI

Part 3. The correct setup to find liters is: 150 mL x 1L/1000mL

Part 4. The molarity of this solution is: 4.6 M HCI

The advantage of Bronsted-Lowry base theory over the Arrhenius base theory is that the Bronsted-Lowry bases can act as proton acceptors.

According to the definition of Bronsted-Lowry, a base is a proton acceptor. In that case, the concept of bases is not limited to only the hydroxide ions.

Thus the advantage of Bronsted-Lowry base theory over the Arrhenius base theory is that the Bronsted-Lowry bases can act as proton acceptors.

Answer:

A) Which brand and amount of fertilizer will work best?

Explanation:

A) is the best answer because it takes into account all of the variables. The variables seem to be the amount of fertilizer, average plant growth, and brand of fertilizer. The independent variables are amount of fertilizer and fertilizer brand. The dependent variable is the plant growth.

B) is not the best answer because it does not include the amount of fertilizer. Because this variable is changing, it is important to consider.

C) is not the best answer because it does not take the type of fertilizer into account. If the researcher were only concerned with how the amount of fertilizer affects plant growth, it would not be necessary to include 3 different types of fertilizer.

D) is not the best answer because this doesn't explain why the researcher used different types of fertilizer.

The number of moles of  Fe₂O₃ that must react to produce 760 kg of Fe are 20.503

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

The reaction is [tex]\rm Fe_2O_3 (s) + 3CO (g) ----- > 2Fe (l) + 3CO_2[/tex]

The mass of Fe is given 760 kg

The molar mass of Fe is 55.9 g/mol

To calculate the number of moles

[tex]n = \dfrac{m}{M} \\\\n = \dfrac{760000}{55.9 g/mol} = 13,669[/tex]

Now, the ratio between Fe and O is 2 : 3

[tex]\dfrac{13,669}{2} \times 3 = 20,503.5[/tex]

convert it into kg = 20.503 mol

Thus, the moles are 20.503 mol

The ΔH fusion used to calculate the energy released when a mass of liquid freezes by using the formula Grams liquid x mol/g x ΔH fusion.

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

Heat of formation or enthalpy is given for any one mole of substance.

And it will be calculated for moles of gases as, so for this first mass will be converted into moles as-

n = W/M, where

W = given mass in grams

M = molar mass in g/mol

and then multiply the given moles by the enthalpy of formation of one mole.

Hence, Grams liquid x mol/g x ΔH fusion is used.

Answer:

If 50.0 grams of HCl were dissolved in enough water to make a solution with a total volume of 5.0 liters, then the molarity of the solution is 0.282M.

How do we calculate molarity?

Molarity of any solution will be calculated by using the below equation:

M = n/V, where

n = moles of solute

V = volume of solvent in L

Moles will be calculated by using the below equation:

n = W/M, where

W = given mass = 50g

M = molar mass = 35.45 g/mol

n = 50/35.45 = 1.41 moles

On putting values in the above equation, we get

M = 1.41mol / 5L = 0.282M

Hence required molarity of solution is 0.282 M.
