Answer:

41.43 mL

Explanation:

First we <u>calculate the mass of NaOH in the original solution</u>:

  • 25.0 % m/v means that in 100 mL of solution, there are 25 grams of NaOH.
  • This means that in 5.80 mL, we would have (5.80 * 25/100) <u>1.45 grams of NaOH.</u>

Then we <u>calculate the volume of the diluted solution</u>, using the grams of NaOH (that remain the same throughout the dilution process):

  • 1.45 g NaOH * \frac{100 mL}{3.50gNaOH} = 41.43 mL

A slice of pizza has 500 kcal. If we could burn the pizza and use all the heat to warm a 50-L container of cold water, what woul
gayaneshka [121]

Answer:

10°C  

Explanation:

Heat gain by water = Heat lost by the slice of pizza

Thus,    

m_{water}\times C_{water}\times \Delta T=Q

<u>For water:  </u>

Volume = 50.0 L

Density of water= 1 kg/L  

So, mass of the water:  

Mass\ of\ water=Density \times {Volume\ of\ water}  

Mass\ of\ water=1 kg/L \times {50.0\ L}  

Mass of water  = 50 kg

Specific heat of water = 1 kcal/kg°C  

ΔT = ?

For slice of pizza:  

Q = 500 kcal

So,

50\times 1\times \Delta T=500  

ΔT = 10°C  

Increase in temperature = 10°C

Match the mixture with the substance// I really need help on this guys (it’s a pic btw)
koban [17]

Answer:

See below  

Step-by-step explanation:

1. Colloid

B) Microscopic insoluble particles that are suspended throughout another substance.

Milk is a colloid. It consists of small fat globules suspended in water.

2. Emulsion

D) Two or more liquids that are not normally mixable.

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.

3. Solution

A) A solute that is evenly distributed within the solvent.

Sugar syrup is a solution of sugar in water.

4)Homogeneous

C) A mixture that has its components distributed evenly within the substance.

A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.
