How do you scale a recipe by changing the portion size

Chemistry
1 answer:
Elina [12.6K]3 years ago
3 0

Answer:

You must change the size of each ingredient by the size of the product. Let's say my recipe calls for 1 bag of flower and 2 eggs. I want to double the amount of product that I make, so I must multiply each of my ingredients by 2. I would now use 2 bags of flower and 4 eggs.

e-lub [12.9K]

Answer:

conductors of electricity when in liquid or aqueous state

high melting point

soluble in water

Explanation:

An ionic substance is any substance that is composed of two ions of opposite charge.

In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.

All ionic substances have a very high melting point and dissolve in water easily.

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters
Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

P.V=n.R.T  

Where:  

P=2 atm is the pressure of the gas  

V is the volume of the gas  

n=1.5 mole the number of moles of gas  

R=0.0821\frac{L.atm}{mol.K} is the gas constant  

T=35\°C+273.15=308.15 K is the absolute temperature of the gas in Kelvin

Finding V:

V=\frac{nRT}{P}

V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}

V=18.97 L

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
