scientific description about the pizza dough doubles its size when it is placed in a warm place . how does this happen

Chemistry
1 answer:
Marina CMI [18]3 years ago
6 0
Answer is: because carbon(IV) oxide is released.
For example if baking soda is used for <span>the pizza dough, than on heat carbon(IV) oxide is product of chemical reaction:
2NaHCO</span>₃ → Na₂CO₃ + CO₂ + H₂O.
If we use yeast (<span>single-celled microorganism)</span>, also carbon(IV) oxide produced, because yeast turns sugars into carbon(IV) oxide.

What is the shortest half life
N76 [4]

Answer:

Hey!

Your answer is element A

Explanation:

Using the graph, the element A's emission of radioactive particles ends approximately after 6 years...

A HALF-LIFE IS "HALF" OF THAT TIME PERIOD!

So if the radiation goes for 6 years the half-life is 6 divided by two which gives you 3 years!

The rest however have a longer half-life...

Because they all end at 14 yrs so their half-life in 7 years!

HOPE THIS HELPS!!

Using chemical equation to find moles of product from moles of reactant
Zolol [24]

Answer:

0.21 mole of C8H18.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

2C8H18 + 25O2 —> 16CO2 + 18H2O

Next, we shall determine the number of mole of C8H18 that reacted and the number of mole water (H2O) produced from the balanced equation.

This is illustrated below:

From the balanced equation above,

2 moles of C8H18 reacted to produce 18 moles of H2O.

Finally, we shall determine the number of mole C8H18 needed to produce 1.90 moles of H2O.

This can be obtained as follow:

From the balanced equation above,

2 moles of C8H18 reacted to produce 18 moles of H2O.

Therefore, Xmol of C8H18 will react to produce 1.90 moles of H2O i.e

Xmol of C8H18 = (2 × 1.90)/18

Xmol of C8H18 = 0.21 mole

Thus, 0.21 mole of C8H18 is needed for the reaction.

Determine the number of valence electrons in each of the following neutral atoms.
Harlamova29_29 [7]

Answer:

Fluorine = 7 v.e.

Sulfur = 6 v.e.

Oxygen = 6 v.e.

Nitrogen = 5 v.e.

Carbon = 4 v.e.

Explanation:

Valence electrons can be easily determined by understanding groups (columns). Every element in. . .

column 3A (13) = 3 v.e.

column 4A (14) = 4 v.e.

column 5A (15) = 5 v.e.

column 6A (16) = 6 v.e.

column 7A (17) = 7 v.e.
