Answer:
Less time is required when using the sponge method than with the sourdough method, and although the sponge method provides hints of the depth of flavor and texture that result from the sourdough method, these characteristics are not as pronounced as they are when using the sourdough method.
Sourdough starter is used to flavor bread and slowly and naturally leaven it. A sponge is the first stage of bread dough preparation in which yeast, liquid, and approximately half of the flour in the recipe are combined to form a thick, wet dough.
What is yeast ?Yeasts are eukaryotic, single-celled microorganisms that belong to the fungus kingdom. The first yeast appeared hundreds of millions of years ago, and at least 1,500 species are now known. They are thought to account for 1% of all known fungal species.
A bubbling mixture of flour, water, and yeast It produces phenomenal results for a low-cost approach: a crust and flavor similar to sourdough, with less of the taste that some sourdough haters can do without due to shortened pre-fermentation.
The sponge method is employed for three distinct reasons: taste, texture, and chemistry. The flavor produced is determined by the ingredients used and the fermenting yeast. The longer they ferment, just like sourdough, the more distinct the flavor.
Thus, A sponge is the first stage of bread dough preparation in which yeast, liquid.

Acetylene is used in oxyacetylene gas welding. Calculate the empirical formula for acetylene given its percent composition:
92.25% C and 7.75% H.
Answer:
[tex]CH[/tex]
Explanation:
Hello!
In this case, given the percent composition of C and H in acetylene, in order to find its empirical formula we compute moles of C and H assuming those percentages as masses:
[tex]n_C=92.25gC*\frac{1molC}{12.01gC} =7.68molH\\\\n_H=7.75gH*\frac{1molH}{1.01molH}=7.67molH[/tex]
Next, since they have the same number of moles we infer they are in a 1:1 subscript ratio on the empirical formula, where is therefore:

PLEASE HELP! (IM GIVING BRAINLIEST) Iron is a transition metal and, as such, can form two types of "oxide" salt compounds, FeO and Fe2O3.
a) How are the iron atoms in each of these formulas different?
b) Explain the electron behavior among iron and oxygen atoms as they bond with one another in both of these compounds.
Answer:
See explanation
Explanation:
Iron exhibits two stable oxidation states, +2 and +3 states. The difference between FeO and Fe2O3 is that, in FeO, Fe is in the +2 oxidation state while in Fe2O3, Fe is in the +3 oxidation state
In FeO, iron looses two electrons which are gained by oxygen as follows;
Fe^2+ + O^2- -----> FeO
In Fe2O3, Fe looses six electrons while oxygen has gained six electrons as shown;
2Fe^3+ + 3O^2- ------>Fe2O3

The diagram below shows a Venn diagram to compare the properties of solids, liquids, and gases.
What property, which only solids have, is in position 1?
definite shape
definite volume
particles that do not move
particles are always in motion
Answer:
definite shape.
Explanation:
This is one of those questions where
1. It depends on what you have been told.
2. it depends on what the marker thinks the answer is.
As long as a substance is above absolute zero, there is some movement at the atom level. It may not be much, and it may be very confined, but the particles do move. That is the second best answer, and very possibly right.
I think your best answer is that solids have a definite shape. When you consider gasses and liquids, they have no definite shape at all. A liquid will take on the shape of the container it is in. So will gasses.
Only solids have a definite shape.. I would pick that, but don't be surprised if it is not right.

According to Newton's laws the statement which is true is statement D as in 'D' ball traveled the greatest distance. and used greatest amount of force.
What is force?
Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Due to electron delocalization, one would predict that the carbon-oxygen bond in acetamide, CH3CONH2, ________.A) is nonpolarB) has more double bond character than the carbon-oxygen bond of acetone, (CH3)2COC) is longer than the carbon-oxygen bond of dimethyl ether, (CH3)2OD) is longer than the carbon-oxygen bond of acetone, (CH3)2COE) is formed by overlapping sp3 orbitals
Answer:
D) is longer than the carbon-oxygen bond of acetone, (CH3)2CO
Explanation:
Delocalization has to to do with a situation in which electrons are not associated with with a single covalent bond in a molecule.
If a double bond is involved in delocalization, then it tends to exhibit greater single bond character. This implies that the bond will be longer than a normal double bond.
If we bring these ideas home to our particular context of CH3CONH2 and acetone, delocalization confers greater single bond character on CH3CONH2 making its C=O bond longer than that of acetone where there is no delocalization.
Suppose 0.035 moles of HCl is dissolved in enough water to produce 750 mL of solution. What is the pH
Answer:
pH = 1.33
Explanation:
Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.
Now we calculate the molar concentration (molarity) of H⁺:
Molarity = moles / volume(750 mL ⇒ 750 / 1000 = 0.750 L)
Molarity = 0.035 moles / 0.750 LMolarity = 0.0467 MThen we calculate the pH of the solution:
pH = -log [H⁺]pH = -log (0.0467 M)pH = 1.33If 0.035 moles of HCl is dissolved in enough water to produce 750 ml of solution, then the pH will be 1.33
What is pH?pH number tells how acidic or basic the liquid is.
HCl is a strong acid, its molecules will fully dissociate
H+ and Cl-
Now, calculate the molarity
[tex]Molarity = \dfrac{moles}{ volume} \\\\Molarity = \dfrac{0.035\; moles }{ 0.750 L} =0.0467 M[/tex]
Calculate the pH of the solution

Hydrochloric acid dissolves solid aluminum hydroxide. What is the net ionic equation of this reaction
Answer:
3 H⁺(aq) + 3 OH⁻(aq) ⇒ 3 H₂O(l)
Explanation:
Let's consider the molecular equation for the neutralization between hydrochloric acid and aluminum hydroxide.
3 HCl(aq) + Al(OH)₃(aq) ⇒ AlCl₃(aq) + 3 H₂O(l)
The complete ionic equation includes all the ions and the molecular compounds.
3 H⁺(aq) + 3 Cl⁻(aq) + Al³⁺(aq) + 3 OH⁻(aq) ⇒ Al³⁺(aq) + 3 Cl⁻(aq) + 3 H₂O(l)
The net ionic equation includes only the ions that participate in the reaction and the molecular compounds.
3 H⁺(aq) + 3 OH⁻(aq) ⇒ 3 H₂O(l)
Hydrochloric acid dissolves solid aluminum hydroxide and the net ionic equation of this reaction is 3H⁺ + 3OH⁻ → 3H₂O.
What is net ionic reaction?Net ionic reactions are those reactions in which all species are represent in their ionic form except spectatore ions, as they are present on both sides of the reaction.
Balanced Molecular chemical reaction between HCl and solid Al(OH)₃ will be represented as:
3HCl(aq) + Al(OH)₃(s) → AlCl₃(aq) + 3H₂O(l)
Now we write the above equation in the ionic form as below:
3H⁺ + 3Cl⁻ + Al³⁺ + 3OH⁻ → Al³⁺ + 3Cl⁻ + 3H₂O
In the above equation Al³⁺ and Cl⁻ are spectator ions as they are present on both side of the chemical reaction. So, net ionic reaction will be represented as:
3H⁺ + 3OH⁻ → 3H₂O
Hence, net ionic reaction will be 3H⁺ + 3OH⁻ → 3H₂O.
