Why does a cake rise when you bake it? ♡

2 answers:

8 0

Because baking soda reacts with the ingredients in cake resulting in trapped carbon dioxide, which give way to a rising batter due to heat. (honestly tres leches is my favorite type of cake)

The reaction of baking soda or baking powder with the liquid in the batter: These ingredients react together and cause air bubbles to form. ... Heat of the oven: The heat of the oven can cause baking powder to react further and cause more air bubbles, and the heat also sets the structure of the cake.

Compare how entropy changes for the following two systems:

DanielleElmas [232]

Answer:

Explanation:

Entropy is concept which the describes the state of randomness or disorderliness of particles of a system. The entropic level depends on two important factors:

1. Temperature

2. Physical state of matter

For system A, in going from solid to liquid by dissolution in water the entropy increases. Solids are the most ordered substances followed by liquids. Gases are the most random.

For system B, moving from gas to a condensed state, there is a huge decrease in randomness of the system. The system tends towards more orderliness as the condensing forces changes a gas to a liquid. For this system, entropy reduces.

What term is used to describe the energy level of any level higher than the ground state of a particle?

Xelga [282]

Answer:

B. Excited state

Explanation:

Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.

The ground state is the lowest energy state available to the electron. This is usually the most stable state.

The excited state is any level higher than the ground state. An electron in an energy level has a definite amount of energy associated with it at that level.

You are given a solution of HCOOH (formic acid) with an approximate concentration of 0.20 M and you will titrate this with a 0.1

jeka57 [31]

Answer:

$\boxed{\text{36 mL}}$

Explanation:

1. Write the balanced chemical equation.

$\rm HCOOH + NaOH $ \longrightarrow$ HCOONa + H$_{2}$O$

2. Calculate the moles of HCOOH

$\text{Moles of HCOOH} =\text{20.00 mL HCOOH } \times \dfrac{\text{0.20 mmol HCOOHl}}{\text{1 mL HCOOH}} = \text{4.00 mmol HCOOH}$

3. Calculate the moles of NaOH.

$\text{Moles of NaOH = 4.00 mmol HCOOH } \times \dfrac{\text{1 mmol NaOH} }{\text{1 mmol HCOOH}} = \text{4.00 mmol NaOH}$

4. Calculate the volume of NaOH

$c = \text{4.00 mmol NaOH } \times \dfrac{\text{1 mL NaOH }}{\text{0.1105 mmol NaOH }} = \textbf{36 mL NaOH }\\\\\text{The titration will require }\boxed{\textbf{36 mL of NaOH}}$
