Photosynthesis

Photosynthesis

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phos, "light", and sunthesis "putting together". In most cases, oxygen is also released as a waste product. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Explanation:

The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)

The relationship between both units is given as;

1 Km = 6.68459e-9 Au

Kulper belt

6.5 billion km = 6.5e9 Km

1 Km = 6.68459e-9 Au

6.5e9 Km = x

Solving for x;

x = 43.45 Au

Alpha Centauri

44 trillion km = 4.4e13

1 Km = 6.68459e-9 Au

4.4e13 km = x

Solving for x;

x = 294121.83 Au

Answer:

2C7H6O3 + C4H6O3 - - - > 2C9H8O4 + H2O

Explanation:

Reactants:

2C7H6O3 + C4H6O3

C = 18

H = 18

O = 9

Products:

2C9H8O4 + H2O

C = 18

H = 18

O = 9

Answer:

D

Explanation:

The goal in this set up is to make sure all units cancel each other.

Since we need to go from grams to atoms, our final unit should be atoms.

Using method of elimination, let's see why other options are wrong.

A - Although 'g' is cancelled out, we are left with moles^2 / atoms

B - Although 'g' is cancelled out, we are left with moles^2 / atoms

C - Although 'mol' is cancelled out, we are left with g^2 / atoms

Explanation:

Atomic radii is measured using the distance between nucleus of 2 atoms rather than the distance between the nucleus and outermost shell because:

- There is no clear/sharp boundary of the orbital. This is why it is called an electron cloud.

- Also, the exact location of the electron is not known. What is known is the probability of finding the electron there.

Due to this, it is not possible to measure the atomic radii precisely. That's why the distance between the nucleus of two atoms is used.

Answer:

19.7 L N2

Explanation:

The volume of the nitrogen gas at STP is equal to 19.72 L.

The ideal gas equation can be defined as an equation that describes the behavior of an ideal gas. This equation gives by the product of the volume and pressure is equal to the product of the moles of gas, gas constant, and absolute temperature.

The mathematical form of the ideal gas law is given as follows:

PV = nRT

Where n is the moles, V is the volume, R is the universal gas constant and P is the pressure.

The temperature of the N₂ , T =  0° C = 273 K

The pressure of the gas at STP, P = 1 atm

The value of the universal gas constant, R = 0.082 atm L/K mol

The number of moles of N₂, n = 0.881 mol

Fill in the values n, R, P, and T in the equation, and we get:

1 × V = 0.881 × 0.082 × 273

V = 19.72 L

#SPJ2

Answer:

[Zn(C₂H₃O₂)₂] = 1.85M (3 sig-figs accurate to 0.01 Molar)

Explanation:

Concentration is defined as amount of solute in a specified volume of solution. That is, Concentration = mass of solute/volume of solution (solution = solute + solvent). When concentration is in terms of Molar values the essential relationship is Molarity(M) = moles solute / volume of solution in liters.

For this problem => first, convert mass of Zn(C₂H₃O₂)₂ into moles and then the volume of solution into liters. Take ratio of moles/volume of solution (L).

=> Molar Concentration = moles of Zn(C₂H₃O₂)₂ / Liters of solution

moles of Zn(C₂H₃O₂)₂ = 85.0 grams Zn(C₂H₃O₂)₂ / formula weight of Zn(C₂H₃O₂)₂  =  85.0g/183.5g·mole⁻¹ = 0.463 mole Zn(C₂H₃O₂)₂.

Volume of solution in Liters = 250ml / 1000ml/L = 0.250 liters

Molarity of  Zn(C₂H₃O₂)₂ solution = 0.463 mole Zn(C₂H₃O₂)₂  /0.250 liters of solution = 1.85 Molar in Zn(C₂H₃O₂)₂

_____________

Note: The symbiology convention for 'molar solution concentration' is to place brackets around the molecular formula. That is, [Zn(C₂H₃O₂)₂] = 1.85M

Answer:

pH = 3.69

Explanation:

HCl is a strong acid. It will disscociates completely into dissoluted ions such that,

[tex][H^+]=2\times 10^{-4}\ M[/tex]

The formula for pH is given by :

[tex]pH=-log[H^+]\\\\pH=-log(2\times 10^{-4})\\\\pH=3.69[/tex]

So, the pH of the solution is 3.69.

Answer: NO

Explanation:

As per the given balanced equation, 2 moles of NO reacts with 2 moles of CO. Hence, 3 g or 1.07 moles of CO needs to react with the same number of moles of NO. But we have only 3 g or 0.1 mole of NO. Hence, NO is the limiting reactant.

A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.

Given 2 moles of NO reacts with 2 moles of CO.

molar mass of NO =  30 g/mol

molar mass of CO = 28 g/mol.

Number of moles in  3 g of CO = 3/28 = 1.07 moles

number of moles in 3 g of NO = 3/30 = 0.1 moles.

1.07 moles of CO needs 1.07 moles of NO. But only 0.1 moles are present.

Therefore, NO is the limiting reactant in this reaction.

#SPJ2

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

How many molecules of CO2 are present?

6 moles

How many atoms of oxygen are present in the reactants?

(6 * 2) + (6 * 1 ) = 12 + 6 = 18

How many atoms of carbon are present in the products?

(6 * 1 ) = 6

How many total atoms are present in C6H12O6?

6 + 12 + 6 = 24 atoms

Is the equation above balanced or unbalanced?

This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.

Answer:

This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.

Explanation:

Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

Answer:

CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."

Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!

Answer:

The correct answer is 639 L H₂

Explanation:

We use the ideal gas equation:

We have the following data:

n = 28.3 mol

T= 297 K

P= 1.08 atm

R= 0.082 L.atm/K.mol (gas constant)

We introduce the data in the gas equation to calculate the volume (V):

PV=nRT

⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L

Therefore, the correct option is  639 L H₂
