Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water H2O and carbon dioxide CO2 chemically react to form the simple sugar glucose C6H12O6 and oxygen gas O2.
What mass of water is consumed by the reaction of 6.49g of carbon dioxide?

Answers

Answer 1

ANSWER:

2.65 g H2O

Explanation:

6.49g (co2) / 44.009g (co2)  x  1 mol (co2) / 1 mol (h2o)  x 1 mol (h2o)    

=0.147 mol H2O

0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)

=2.65 g H2O

Explanation:

According to the second law of thermodynamics, the energy of the universe is conserved but the entropy of the universe is continuously increasing.

What is the second law of thermodynamics?

The second law of thermodynamics put some restrictions on the direction of heat transfer and attainable efficiencies of heat engines. This law stated that any spontaneously happening process will lead to an escalation in the entropy (S) of the universe.

This law explains that the entropy of an isolated system will never decrease with time. Mathematically, the 2nd law of thermodynamics:

ΔS (universe) > 0

where ΔS of the universe is the change in the entropy of the universe.

The second law of thermodynamics provides the criterion for the feasibility of any physical or chemical process. A physical or chemical process cannot take place unless it must follow both the 1st and 2nd laws of thermodynamics.

how an ionic compound made up of charged particles can be electrically neutral

Answers

Answer:

Explanation:

Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.

A 7.28 g sample of chromium metal was heated to produce chromium oxide. The weight of the compound was 10.63 g. What is the percent chromium in this compound?

Answers

Answer:

68.48%

Explanation:

The percent mass of an element in a compound tells us about the amount of such element contributed to the total compound.

In this case, 7.28 g sample of chromium metal was heated to produce chromium oxide with weight of 10.63 g. The percent mass of chromium in chromium oxide can be calculated by using the formula:

%mass of Cr = mass of Cr/mass of Chromium oxide × 100%

%mass of Cr = 7.28/10.63 × 100

%mass of Cr = 0.6848 × 100

%mass of Cr = 68.48%

What is the net ionic equation for this reaction? • Hint: In this reaction, nickel exhibits its most common oxidation state of +2. • Be sure to include the charge for each ion in the net ionic equation. Provide your answer below: (s) + (aq) → *(n)

Answers

Answer:

Pb²⁺(aq) --> Ni²⁺(aq)

Explanation:

The equation of the reaction is given as;

Ni(s) + Pb(NO₃)₂(aq) --> Pb(s) + Ni(NO₃)₂(aq)

In writing the ionic equation, we break the aqueous compound into ions. The solid and liquid compounds are ignored.

We have;

Pb²⁺(aq)  + NO₃²⁻(aq) -->  Ni²⁺(aq)  + NO₃²⁻(aq)

Canceling the spectator ions;

Pb²⁺(aq) --> Ni²⁺(aq)

Answer:

Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)

Explanation:

The complete ionic equation of this reaction is

Ni(s)+Pb2+(aq)+2 NO−3(aq)→Ni2+(aq)+2 NO−3(aq)+Pb(s)

The nitrate ions are spectator ions and can be removed from the equation, giving us

Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)

A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL

Answers

Answer:

14

Explanation:

70g/(35mL-30mL)=14g/mL

If a rock with a mass of 70 grams is dropped into a graduated cylinder with 30 milliliter of water in it. The water level rose to 35 milliliters, then the density of the rock in gram / milliliter would be  14  gram / milliliter.

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

The mass of ṭhe rock = 70 grams

The volume of the rock = 35 milliliters - 30 milliliters

                                       = 5 milliliters

The density of the rock = mass of the rock / volume of the rock

                                       =70 grams / 5 milliliters

                                       = 14  gram / milliliter

Thus, the density of the rock would be 14 gram / milliliter.

What are elements?

Element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.Each element has atoms which are unique to itself.

In the reaction of: ????2O4 (g) ⇌ 2????O2(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of ????2O4 = 0.0500 ????. What are the equilibrium concentrations of ????2O4 and ????O2 under these conditions?

Answers

Answer:

[N₂O₄] = 0.00411 M

[NO₂] = 0.0918 M

Explanation:

In the reaction of: N₂O₄(g) ⇌ 2 NO₂(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of N₂O₄ = 0.0500 M. What are the equilibrium concentrations of N₂O₄ and NO₂ under these conditions?

Step 1: Given data

Initial concentration of N₂O₄: 0.0500 M

Equilibrium constant (Kc): 0.513

Step 2: Make an ICE chart

        N₂O₄(g) ⇌ 2 NO₂(g)

I        0.0500           0

C           -x              +2x

E      0.0500-x        2x

Step 3: Find the value of "x"

The equilibrium constant is:

Kc = [NO₂]² / [N₂O₄]

0.513 = (2x)² / (0.0500-x)

4x² + 0.513 x -0.02565

We solve for x and we get x₁ = 0.0458942 and x₂ = −0.558894 (neglected).

Step 4: Calculate the concentrations at equilibrium

[N₂O₄] = 0.0500-x = 0.00411 M

[NO₂] = 2x = 0.0918 M

What is the volume in liters of 222 g of neon if neon has a density of 0.900 g/L?

Answers

Answer:

[tex]V=247L[/tex]

Explanation:

Hello there!

In this case, since the density is defined as the degree of compactness of a substance and is computed by diving the mass over the volume it occupies:

[tex]\rho =\frac{m}{V}[/tex]

Given the density and the mass of the neon, we can compute its density as shown below:

[tex]V=\frac{m}{\rho} =\frac{222g}{0.900g/L}\\\\V=247L[/tex]

Best regards!

The volume of neon in liters is 246.67 L.

To calculate the volume of neon, we use the formula below.

Formula:

D = m/V............... Equation 1

Where:

D = Density of neonm = mass of neonV = Volume of neon.

make V the subject of the equation.

V = m/D............... Equation 2

From the question,

Given:

m = 222 gD = 0.900 g/L

Substitute these values into equation 2

V = 222/0.9V = 246.67 L.

Hence, The volume of neon in liters is 246.67 L.
