Answer:

They tenderize the product by coating and weakening the gluten bonds within the structure.

Even though they contain little or no moisture, they provide the illusion of wetness. ...

They enable browning.

They help move heat through the product, perpetuating the baking process.

What is an example of a Low Energy-created depositional environment?
sweet-ann [11.9K]

Answer:

River flood plains, swamps, lakes, lagoons, marshes, and offshore.

Explanation:

Slow-moving currents prevent coarse-grained sediment from migrating into low-energy depositional environments. Fine materials can be carried long distances before they can settle out in the absence of waves and currents.

will give brainliest!! please help ! .. Calculate the total pressure of the mixture in atmospheres ( atm ).
nordsb [41]

Answer:

13.94 atm

Explanation:

From the question given above, the following data were obtained:

Pressure of H₂ = 2 atm

Pressure of NH₃ = 303 KPa

Pressure of CO₂ = 3000 mmHg

Pressure of N₂ = 3800 torr

Total pressure (Pₜ) in atm =?

Next, we shall convert 303 KPa, 3000 mmHg and 3800 torr to atm.

This can be obtained as follow:

Converting 303 KPa to atm

101.325 KPa = 1 atm

Therefore,

303 KPa = 303 KPa × 1 atm / 101.325 KPa

303 KPa = 2.99 atm

Thus, 303 KPa is equivalent to 2.99 atm.

Converting 3000 mmHg to atm

760 mmHg = 1 atm

Therefore,

3000 mmHg = 3000 mmHg × 1 atm / 760 mmHg

3000 mmHg = 3.95 atm

Thus, 3000 mmHg is equivalent to 3.95 atm

Converting 3800 torr to atm

760 torr = 1 atm

Therefore,

3800 torr = 3800 torr × 1 atm / 760 torr

3800 torr = 5 atm

Thus, 3800 torr is equivalent to 5 atm.

Finally, we shall determine the total pressure of the mixture as follow:

Pressure of H₂ (P₁) = 2 atm

Pressure of NH₃ (P₂) = 2.99 atm

Pressure of CO₂ (P₃) = 3.95 atm

Pressure of N₂ (P₄) = 5 atm

Total pressure (Pₜ) in atm =?

Pₜ = P₁ + P₂ + P₃ + P₄

Pₜ = 2 + 2.99 + 3.95 + 5

Pₜ = 13.94 atm

Therefore, the total pressure of the mixture is 13.94 atm

What mass of oxygen is needed to burn 54.0 grams of butane c4h10
Jobisdone [24]

The moles of oxygen required to burn Butane is 6 moles.

<h3>What is a Combustion Reaction?</h3>

A reaction in which fuel gets oxidised by an oxidising agent producing a large amount of heat is called a combustion reaction.

In this question

Butane is burnt with oxygen

Molar mass of C₄H₁₀ = (12.0×4 + 1.0×10) g/mol = 58.0 g/mol

Molar mass of O₂ = 16.0×2 g/mol = 32.0 g/mol

Balanced equation for the reaction:

2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O

Mole ratio C₄H₁₀ : O₂ = 2 : 13

The given mass = 54grams

moles = 54/58 = 0.93 moles

The mole of oxygen required =

0.93/ x = 2/13

0.93*13/2 = x

x = 6.045 moles

Therefore 6 moles of oxygen are required to burn Butane.

Science Grade 8
FinnZ [79.3K]
Sound waves are produced by air flow coming from our lungs passing through our throat, more specifically our larynx and moving with two folds of tissue called vocal chords. The sound is made by the vibration of vocal chords, so the more stretched the chords are over the larynx, their frequency of vibration is higher, therefore producing higher-pitched sounds.
