Answer: Elements or compounds that enter are Reactants.
The substances that are formed are the Products
Reactants in C6H12O6 + 602 ---> 6CO2 + 6H2O are C₆H₁₂O₆ + 6 O₂
Reactants in 6 CO2 + 6H2O --->C6H12O6 + 602 are 6 CO₂ + 6 H₂O
Reactants in 2 H2 +O2 ---> 2 H2O are 2 H₂ +O₂
Reactants in 2 H2O ---> 2 H2 + O2 are 2 H₂O
Explanation:
The number of atoms in the reactants have to balance with the number of atoms in the products.
The first two examples given are for metabolism of carbohydrates (similar to combustion of hydrocarbons) and photosynthesis.
how do i find the formal of newtons third law
Answer:
Newton's third law is: For every action, there is an equal and opposite reaction.
Explanation:
FA = −FB. if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction

⚠️An irregular piece of iron has a mass of 78.7 grams. When placed in a graduated cylinder with 30 mL of water, the water rises to the 35 mL ⚠️
Answer:
The density of the iron is: 15.74g/cm3
Explanation:
-To determine the density of something, you have to divide the mass and the vol.
-mass/volume = density or, m/v = d
-The mass of the iron is: 78.7 grams
-The volume of the iron is 5mL
In order to find the density, you have to divide:
m/v = d
78.7g ÷ 5mL = 15.74
Hope This Helps (:

What do cuticles do for land plants that were not necessary for ancestors that lived in the water?
Cuticles allow them to grow bigger and taller.
Cuticles help them transport water.
Cuticles help prevent water loss.
Cuticles allow the performance of photosynthesis.
HELP PLS AND THX
Answer:prevention of water loss would be unnecessary
Explanation:
edge 2021
Cuticles are protective lining in the epidermal layer of plants. Cuticles helps to reduce water loss and protect the plants from environmental stresses.
What is cuticles?Cuticle is an organism's external layer or area that makes touch with the environment. The epidermis secretes the dead, noncellular cuticle in many invertebrate species. In humans, the cuticle is the epidermis, and this layer may include colours and chitin, similar to arthropods.
The cuticle is a protective coating that protects the epidermal cells of leaves and other organs while preventing water loss in some higher plants.
It is made up of cutin, a waxy, water-repellent compound related to suberin that is present in the corky tissue's cell walls. Hence, option c is correct.
