Name 3 sources of carbohydrates for the production of an alcoholic drink

Answer:

Ag > Fe > Al

Explanation:

The values of the specific heat capacity of the elements are given as;

Aluminum = 0.897 J/g*K  

Iron=0.449 J/g*K  

Silver=0.235 J/g*K

Specific heat capacity basically refers to how much heat is required to change the temperature of a unit mass of a substance by a degree. Elements with high specific heat capacity would require higher energy compared to elements with lower values,

Aluminium (Al) has the highest specific heat capacity, hence it wold require more energy to cause a change in temperature. Aluminium would be the lowest.

Silver (Ag) has the lowest specific heat capacity hence it would require less energy to cause a change in temperature. Silver wold be the highest.

The middle would be iron (Fe).

The rank is given as;

Ag > Fe > Al

Answer:

CLEANER

Explanation:

Independent variable is the variable in an experiment that is changed or manipulated by the experimenter in order to bring about a measurable response.

In this question, Marie notices that the current cleaner she is using on her shower is not cutting through the hard water build-up that has accumulated. She decides to purchase 3 other cleaners to see if one of them will do a better job of cutting through the stains. The CLEANERS being changed in this experiment is the INDEPENDENT VARIABLE.

Answer:

The final temperature is 566°K

Explanation:

Given

V1 = 0.444L

T1 = 0.00°C

P1 = 79.00 kPa

V2 = 1880mL

P2 = 38.70 kPa

Required

Determine the final temperature of the gas

To answer this, we make use of idea gas law equation.

This is:

(P1V1)/T1 = (P2V2)/T2

Convert V1 to mL

V1 = 0.444L

V1 = 0.444 * 1000mL

V1 = 444mL

Convert T1 to Kelvin

T1 = 0.00°C

T1 = 0.00 + 273K

T1 = 273K

Substitute these values in the given equation.

(P1V1)/T1 = (P2V2)/T2

(79 * 444)/273 = (38.70 * 1880)/T2

35076/273 = 72756/T2

Cross Multiply

35076 * T2 = 273 * 72756

35076T2 = 19862388

Make T2 the subject

T2 = 19862388 ÷ 35076

T2 = 566K (approximated)

Hence, the final temperature is 566°K

Answer:

the popultion of it

Explanation:

NH₄+ , (CO₃)₂- , OH- , (PO₄)₃- are all examples of polyatomic ions.

A covalent bound type of collection of two or more atoms or of a metal complex that can be said as behaving as a single unit and that has a net charge which is not zero is referred to as a polyatomic ion or a molecular ion.

Depending on the terminology , a polyatomic ion may or may not be referred to as a molecule. The Greek word poly- that means "many," although even ions made of just two atoms are frequently referred to be polyatomic.

A polyatomic ion may also be referred to as a radical  (or less commonly, as a radical group). 

The term "radical" today refers to a variety of free radicals, which are species with an unpaired electron and do not require a charge.

The hydroxide ion, which has the chemical formula OH- and is made up of one oxygen and one hydrogen atom and has a net charge of 1, is a straightforward example of a polyatomic ion.

A nitrogen atom, four hydrogen atoms, and a charge of +1 make up an ammonium ion, which has the chemical formula NH₄+.

In the context of acid-base chemistry and the production of salts, polyatomic ions are frequently helpful.

A polyatomic ion is frequently thought of as the conjugate base or acid of a neutral molecule. For instance, the polyatomic hydrogen (H₂) sulphate anion (SO₄) is the conjugate base of sulfuric acid (H₂SO₄). The sulphate anion (SO₄)₂ is created when another hydrogen ion is eliminated.

Answer:

78kJ

Explanation:

Energy change = Energy in (reactants) - Energy out (products)

According to this question, energy is released, meaning that the reaction is EXOTHERMIC. Hence, the energy change will be negative (-) i.e bond energy of reactants is greater than bond energy of products.

Energy in = bond energy of reactants = 43kJ

Energy out = bond energy of products = ?

Energy change of exothermic reaction = -35kJ

Therefore;

-35kJ = 43kJ - x

x = 35kJ + 43kJ

x = 78kJ

The bond energy of the products is 78kJ.

Answer:

10 g H₂SO₄

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

Given:   8 g SO₃

RxN:   SO₃ + H₂O → H₂SO₄

Step 2: Identify Conversions

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of SO₃ - 32.07 + 3(16.00) = 80.07 g/mol

Molar mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 3: Stoichiometry

[tex]8 \ g \ SO_3(\frac{1 \ mol \ SO_3}{80.07 \ g \ SO_3} )(\frac{1 \ mol \ H_2SO_4}{1 \ mol \ SO_3} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )[/tex] = 9.80042 g H₂SO₄

Answer:

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:

Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL

Therefore, the correct answer is option B.

Explanation:

888 grams is a mass of ether that the bottle can hold.

Explanation:

The density of the substance is defined as a mass of substance present in the unit volume of the substance.

[tex]Density=\frac{Mass}{Volume}[/tex]

Given:

A bottle with a capacity of 1.2 Liters.

The density of ether = 0.74 g/mL

To find:

The mass of ether hold by a given bottle.

Solution:

The volume of bottle = V = 1.2 L

[tex]1 L = 1000 mL\\V = 1.2 L=1.2\times 1000 mL= 1200 mL[/tex]

The density of the ether = d = 0.74 g/mL

The mass of ether that bottle can hold = m

Volume of ether required = Volume of bottle = V = 1200 mL

Using the formula of density:

[tex]d=\frac{m}{V}\\0.74 g/mL=\frac{m}{1200 mL}\\m=0.74 g/mL\times 1200 mL= 888 g[/tex]

888 grams is a mass of ether that the bottle can hold.

Answer:

Second.

Explanation:

There are four types or kinds of the laws of thermodynamics, but in this question we are actually considering the second law of thermodynamics.

The second law of thermodynamics, in a simple sense means that energies can flow in an equilibrate manner. It can also be stated as the total entropy of the universe. The second law is normal refer to as Law concerning Entropy.

Thus, filling the gap in the Question above. Note that the word written in capital letters is the missing word.

"The SECOND law of thermodynamics states that when two objects of different temperature are in contact, heat energy will flow from the hotter to the cooler object."

Answer:

Don not sure if you got my last email I sent you a text but different question

Explanation:

1) from the periodic table for example if u looking for K it is from the group 1A so the valancey = +1 that is mean it loses one electron to reach a stable state. and this applied for the 1A , 2A, 3A groups.

if u looking for N it is from group 5A so its valency is -3

so it gain 3 electrons to reach a stable state to complete its orbital to 8 electrons. this applied to 5A, 6A,7A

for the transition metals and simimetals other rules.

2) neutral if the element does not hold any charge like

H2, O2, N2, Fe, Au, Cu ...

isotope : if the 2 elements have same symbol and atomic number but they differ in the mass number because the have different numbers of neutrons.

if the element is charged then it is considered as an ion ex: Fe2+ then it is iron cation ( +ion)

F- then it is fluoride anion (-ion)

Explanation:

Explanation:

Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula.

Answer:

No

Explanation:

Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula.

Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnet, the polarization of the irons atoms is random. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects. This is why a piece of iron that is exposed to a magnet becomes magnetic for some time afterward.
