What is the inventory of an atom?

An atom inventory is a list or table of the number of atoms of each element in a chemical compound or participating in a chemical reaction.

Are you allowed to mess around with subscripts when balancing equations?

This is the one to leave to the last. Remember, you cannot change a subscript to balance the equation, nor can you add in new compounds.

What elements do you balance first when balancing an equation?

The Law of Conservation of Mass states that the mass of the reactants must balance the mass of the products. To balance a chemical equation, the atoms of both the elements and molecules on the reactant side (left side) and product side (right side) must be equal to each other.

Is the formula of photosynthesis balanced?

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

What is the formula for photosynthesis in words?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What is the end product of photosynthesis?

Glucose

Why is photosynthesis a balanced equation?

Reactions must be balanced, meaning there needs to be same number each atom on the reactant side as there is on the products side. As you can see, there are 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation. This makes the equation balanced.

Which organ removes carbon dioxide from your body?

Your lungs remove carbon dioxide from your body, so they are also part of the excretory system. More organs of the excretory system are listed below (Table below).

Which is the best description of Photophosphorylation?

Answer Expert Verified. Photophosphorylation is a process that occurs during photosynthesis in plants. It is the conversion of ADP (Adenosine Diphosphate) into ATP (Adenosine Triphosphate) using light energy. ATP (Adenosine Triphosphate) is the energy currency of life of all living organisms.

What are the names of the two main stages of photosynthesis?

There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

How do plants get the carbon dioxide they need for photosynthesis?

For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. During photosynthesis, the oxygen gas produces goes out through the leaves of the stomatal pores.

What happens during dark stage of photosynthesis?

The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and other organic molecules necessary for cell function and metabolism.

During which phase of photosynthesis is carbon dioxide used?

Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced.

What is the dark reaction?

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.

What happens to carbon dioxide molecules in the Calvin cycle?

What happens to carbon dioxide molecules in the Calvin cycle reactions? carbon dioxide molecules are bonded together with the electrons and H’s from NADPH to form glucose. the caretanoids don’t photosynthesize as well, they can’t produce as much glucose so they shut down the oxygen of leaves.

What is the source of the carbon dioxide that is used in photosynthesis?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

What is needed by a leaf to make food?

The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis. During the process of photosynthesis, plants release oxygen into the air.

Do plants release carbon dioxide or oxygen?

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

Where does carbon dioxide come from?

Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.

What are 3 sources of CO2?

There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.

What are the side effects of carbon dioxide?

Exposure to CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions.

What produces the most CO2?

Main sources of carbon dioxide emissions

  • 87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil.
  • The largest human source of carbon dioxide emissions is from the combustion of fossil fuels.
  • The 3 types of fossil fuels that are used the most are coal, natural gas and oil.

What is the biggest contributor to global warming?

In the effort to understand and address global climate change, most analysis has focused on rapidly rising emissions of carbon dioxide (CO2) and options for reducing them. Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming.

What contributes most to global warming?

carbon dioxide

Which country has the lowest carbon footprint?

Tuvalu

Who is the world’s biggest polluter?

In 2019, China was the biggest emitter of fossil fuel carbon dioxide (CO2) emissions. With a share of almost 30 percent of the world’s total CO2 emissions that year, this was roughly twice the amount emitted by the second largest emitter the United States.

What country has the best carbon footprint?
