glucose ethanol and co2

please follow me and mark it brainliest

Answer:

In anaerobic respiration yeast breaks down glucose, forming ethanol and carbon dioxide as its waste products. When the glucose is nearly used up, and provided that oxygen is present, yeast uses the ethanol as a respiratory substrate to produce carbon dioxide and water in aerobic respiration.

Answer: The four ions formed are [tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]

Explanation:

Electrolysis is the process where electricity is used to drive chemical reactions.

In the electrolysis of aqueous solution of sodium chloride, hydrogen gas produces at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode and the sodium hydroxide remains dissolved in the solution.

The reactions will be :

[tex]NaCl\rightarrow Na^++Cl^-[/tex]

[tex]H_2O\rightarrow H^++OH^-[/tex]

Hence, electrolysis of an aqueous solution of sodium chloride lead to the formation of four ions,[tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]

Answer:

The organism in the food chain responsible for transforming radiant energy into chemical energy is;

Grass

Explanation:

Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;

6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂

Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass

Answer:

Liquid takes the shape of container, so it will always touch the walls of the box in which you put it.

Explanation:

We know that a solid has a definite shape and a definite volume hence it occupies only its own volume in the box, it does not touch the walls of the box.

However, a liquid does not have a definite shape and volume. It occupies the volume of the box. Therefore, the liquid water must definitely touch the walls of the box.

Answer:

C. A one (1) is assumed when there is no coefficient

Explanation:

The following chemical equation is given in the attachment:

2H2 + O2 → 2H2O

In this reaction, Hydrogen (H2) and oxygen (O2) gases are the reactants and they combine to form H2O, which is the product. It is necessary that, in accordance to the law of conservation of matter, the same number of atoms of each elements on the reactant side equates that on the product side. When this happens, the equation is said to be BALANCED.

However, to balance an equation, COEFFICIENTS are used. In this equation above, coefficients 2 is used in front of both H2 and H2O but no coefficient is used in front of O2. This is because 1 mole of oxygen is on the reactant and product side respectively. However, one is assumed when no coefficient is written i.e. O2 means 1 mole of oxygen molecule.

1 month i believe sorry if im wrong

Explanation:

Answer:

V₂ = 236.84 mL

Explanation:

The relation between pressure and volume is inverse.

We can write it as follows :

[tex]P_1V_1=P_2V_2[/tex]

We have,

P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.

So,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]

So, the new volume of the gas is 236.84 mL.

first find the atomic weight of CH3 which would be

atomic weight: 12.011 (3×1.008) = 36.32 g/mol

then find the moles in the given mass

36.32 ÷ 45.7 = 0.794

Answer:

what is the formula?

Explanation:

Answer:

An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

Explanation:

Answer:

C: electrons is the 3s orbital are higher than those in the 2s orbital

Explanation:

Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.

Also from basics we know that the energy of an orbital increases as the quantum number increases.

Answer:

Explanation:

A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.

Answer:

0.0493 moles de Titanio

Explanation:

Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:

Volumen de la esfera:

Volumen esfera  = 4/3π * Radio³

Volumen = 0.5236cm³

En m³ (1m³ = 1x10⁶cm³):

0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³

Masa en gramos:

5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio

Moles -Masa molar Ti: 47.867g/mol-:

2.36g de Titanio * (1mol / 47.867g) =

Answer:

T₂ = 800 K

Explanation:

Given that,

Initial temperature of the gas, T₁ = 127°C = 400 K

Initial volume, V₁ = 10 L

Final volume, V₂ = 20 L

We need to find the new temperature.

The volume of a gas is directly proportional to its Kelvin temperature.

Let T₂ is the new temperature. So,

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K[/tex]

So, the new temperature of the gas is 800 K.

Answer:

2 NaF + Br2 --> 2NaBr + F2

Explanation:

Well first I notice that there are two flourines on the products side so we need to put a 2 of NaF. Now there are 2 sodiums on the products side so we have to put another two in front of NaBr.

2 NaF + Br2 --> 2NaBr + F2

Answer:

F = 1000 g cm/s²

Explanation:

Let the weight of 1 ball is 50 gram

Acceleration, a = 20 cm/s²

We need to find the force exerted by a golf ball. We know that,

F = ma

So,

F = 50 g × 20 cm/s²

F = 1000 g cm/s²

So, the required force is 1000 g cm/s².

Answer:

3000 Nm^2

Explanation:

We must remember that pressure is defined as force per unit area.  

We have been given the following information in the question;

Area of the tank= 1.5 m^2

Weight of water in the tank = 4500N

And;

P = F/A

F= force

A = area

P = 4500 N/1.5m^2

P= 3000 Nm^2
