Which statement best describes the relationship between photosynthesis and cellular respiration?
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
Photosynthesis is part of the carbon cycle, and cellular respiration is not.
Only plants perform photosynthesis, and only animals perform cellular respiration.
Photosynthesis releases carbon into the atmosphere, and cellular respiration removes carbon from the atmosphere.

Answers

Answer:

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

The first option clearly expresses the relationship between photosynthesis and cellular respiration.

Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.

In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.

Answer:

Protons and Neutrons have approximately the same mass.

Equal numbers of protons and electrons make an atom neutral.

Protons have a positive charge

Explanation:

Protons and Neutrons have approximately the same mass. - both are 1 amu

Equal numbers of protons and electrons make an atom neutral. - protons are +1 and electrons are -1, so they cancel each other if there are equal amounts.

Protons have a positive charge - this is true.

how molecules react to an increase in temperature.

Answers

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Explanation:

Please help, How would you define what a chemical reaction and an equation is? Give an example.How would you know if a chemical reaction is balanced? Give an example.

Answers

Answer:

A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.

Explanation:

In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.

Answers

Answer:

A. Zinc (Zn) reacting with hydrochloric acid (HCl)

Explanation:

The reaction of Zinc with hydrochloric acid is an irreversible chemical process.

What makes a reaction reversible;

it must be involved in reversible chemical processes, no matter how small the extent of the reversibility. the rate of forward reaction must be equal to the backward one.

So, hydrochloric acid when reacting with Zinc will give a complete chemical change that will go into completion.

How to calculate the number of molecules in 18g of H2O

Answers

We, know molecular mass of water is, M = 16 g/mol .

Given mass of water, m = 18 g.

We know, number of moles is given by :

[tex]n = \dfrac{18\ g}{16 \ g/mol}\\\\n = 1.125\ moles[/tex]

Now, 1 mole of any compound contains 6.022 × 10²³ molecules.

So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =

6.77 × 10²³ molecules.

Hence, this is the required solution.

Answers

Answer:

C

I think not positive good luck tho

A heavily forested area is one that has a dense and large number of trees. The areas like mountainous tracks or the protected frosts areas of wildlife.

In order to have solar collectors that meet the demands of energy generation. Some parts of the forests may have to clear off. As for collecting the sunlight, there needs to be clear ground. As trees and forests absorb insolation.

Hence the option D is correct, trees need to to be cleared for working efficiently.

A sample of oxygen gas has a volume of 150 mL when its pressure is 0.587 atm at 155 K. If the pressure and temperature are increased to STP, what will the new gas volume be?​

Answers

Answer:

V₂ = 155.17 mL

Explanation:

Given data:

Initial volume = 150 mL

Initial pressure = 0.587 atm

Initial temperature = 155 K

Final temperature = 273.15 K

Final volume = ?

Final pressure = 1 atm

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 0.587 atm × 150 mL × 273.15 K / 155 K × 1 atm

V₂ = 24050.86 atm .mL. K / 155 K.atm

V₂ = 155.17 mL

of water?
A. 0.33 mol/kg
B. 12 mol/kg
C. 3 mol/kg
D. 2 mol/kg

Answers

The molality of a solution : m = 0.33 mol/kg

Further explanation

Given

2 moles of NaOH in 6 kg  of water

Required

The molality

Solution

Molality shows how many moles are dissolved in every 1000 grams of solvent.

m = n x (1000/p)

m = Molality

n = number of moles of solute

p = solvent mass (grams)

Input the value :

solute : NaOH

solvent : water

m = 2 moles : 6 kg

m = 0.33 mol/kg

Answer:

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  is 39 passengers

Explanation:

The given parameters of the cylinder representing the fuselage are;

The length of the cylinder, l = 30.0 meters

The width of the cylinder, w = 2.5 meters

The thickness of the cylinder, t = 2.5 mm = 0.0025 meters

The volume of the metal required to make the fuselage cylinder, V = (π·w²/4 - π·(w - 2·t)²/4) × l

Therefore, by substituting the known values, we have;

V = (π × 2.5²/4 - π×(2.5 - 2×0.0025)²/4) × 30 = 0.58845957392

The volume of the metal required to make the fuselage cylinder, V≈ 0.58846m³

The given density of steel = 7.87 g/cm³ = 7870 kg/m³

The given density of aluminum = 2.70 g/cm³ = 2,700 kg/m³

Mass = Density × Volume

The mass of the fuselage made with steel = The given density of steel × The volume of the metal required to make the fuselage cylinder

∴ The mass of the fuselage made with steel = 7870 × 0.58846 ≈ 4631.18

The mass of the fuselage made with steel ≈ 4631.18 kg

Similarly, the mass of the fuselage made with aluminum = 2,700 × 0.58846 ≈ 1588.84

The mass of the fuselage made with aluminum ≈ 1588.84 kg

The total mass the Embraer E170 could carry = The mass of the fuselage made with aluminum + The mass of the 78 passengers

The average mass of each passenger = 79 kg

∴ The total mass the Embraer E170 could carry ≈ 1588.84 + 78 × 79 = 7750.84

The total mass the Embraer E170 could carry ≈ 7750.84 kg

The extra mass the Embraer E170 could carry when made of steel = (The total mass the Embraer E170 can carry) - (The mass of the fuselage made with steel)

∴ The extra mass the Embraer E170 could carry when made of steel = 7750.84 - 4631.18 = 3119.36

The extra mass the Embraer E170 could carry when made of steel ≈ 3119.36 kg

The number of passengers the Embraer E170 could carry when made of steel  = (The extra mass the Embraer E170 could carry when made of steel)/(The average mass of one passenger)

∴ The number of passengers the Embraer E170 could carry if its fuselage was made of steel  = 3119.36 kg/(79 kg/passenger) ≈ 39.489 passengers

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  ≈ 39 passengers (we round down when counting people which are whole quantities)

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?

Answers

Answer:

19.5g

Explanation:

Given parameters:

Volume of propane gas = 9.95L

Unknown:

Mass of propane gas =  ?

Solution:

To solve this problem, find the number of moles first.

    At STP;

        22.4L of gas makes up 1 mole

         9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex]    = 0.44mole

So;

   Mass of propane gas  = number of moles x molar mass

Molar mass of propane  = 3(12) + 8(1)  = 44g/mol

    Mass  = 0.44 x 44  = 19.5g
