Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process. So, the answer is A.

what is a solution for deforestation
(full sentences please)
The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

Plants use sunlight as energy to convert carbon dioxide and water into glucose and oxygen. Which best describes
the reaction?
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the
products
O The law of conservation of energy indicates the same amount of carbon will be found in the reactants as in the
products
The law of conservation of mass indicates the same amount of glucose will be found in the reactants as in the
products
O The law of conservation of energy indicates the same amount of glucose will be found in the reactants as in the
products
Answer:
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products
Explanation:
The reaction between carbon dioxide and water in the presence of sunlight to produce glucose and water strictly follows the law of conservation of mass.
Let us give the reaction expression:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
According to the law of conservation of mass, matter is neither created nor destroyed but new compounds are formed during a chemical reaction.
From the given reaction expression, we can clearly see that 6 moles of carbon on the reactant side will produce 6 moles of carbon on the product side.
Therefore, the law obeys the law of conservation of mass.

When 25.0 g of Mg with 25.0 g of l2, what was the limiting reactant? How many grams of the limiting reactant are left over? How many grams of the other reactant (in excess) is left over?
Limiting reactant = I₂
Mass of Mg leftover = 22.628 g
Further explanationGiven
Reaction between 25.0 g of Mg with 25.0 g of l₂
Required
The limiting reactant
mass of limiting and excess left over
Solution
Reaction
Mg + I₂⇒ MgI₂
mol Mg = 25 g : 24.305 g/mol = 1.029
mol I₂ = 25 g : 253.809 g/mol = 0.098
Limiting reactant = I₂
Excess reactant = Mg
The limiting reactant will be used up
Mol excess(unreacted) :
=1.029 - 0.098
=0.931
Mass I₂ left over :
= 0.931 x 24.305
= 22.628 g

How many hydrogen molecules are in 1.2 moles of hydrogen?
Answer:
7.22 x 10²³molecules
Explanation:
Given parameters:
Number of moles of hydrogen = 1.2moles
Unknown:
Number of molecules of hydrogen = ?
Solution:
From the concept of moles, a mole of a substance contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ molecules;
So; 1.2 moles of hydrogen = 1.2 x 6.02 x 10²³ molecules;
= 7.22 x 10²³molecules

This chemical equation represents the combustion of propane. When correctly balanced, the coefficient for water
is
16.
2.
8.
4.
Answer:
4
Explanation:
The following equation, which depicts the combustion of propane, is given in this question as follows:
C3H8 + 02 → CO2 + H2O
However, this equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product side. To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both side correlates.
The balanced equation is as follows:
C3H8 + 502 → 3CO2 + 4H2O
Therefore, the coefficient for water (H2O) after balancing the equation is 4.
The study of chemicals is called chemistry.
The correct answer is D.
The equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product sides.
To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both sides correlates.
After balancing the equation is as follows:
[tex]C_3H_8 + 50_2 → 3CO_2 + 4H_2O[/tex]
Hence, the correct answer is 4 which shows the balanced water.

why can nuclear fusion occur in the core of a star
Answer:
When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy. ... This is because a single helium atom contains less mass than two hydrogen atoms. The excess mass is released as energy.

Magnesium reacts with iron chloride solution. Calculate the mass of iron produced in mg
Answer: 0.000187 mg of iron is produced.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Mg=\frac{0.120g}{24g/mol}=0.005moles[/tex]
[tex]3Mg+2FeCl_2\rightarrow 2Fe+3MgCl_2[/tex]
As [tex]FeCl_2[/tex] is the excess reagent, [tex]Mg[/tex] is the limiting reagent.
According to stoichiometry :
3 moles of [tex]Mg[/tex] give = 2 moles of [tex]Fe[/tex]
Thus 0.005 moles of [tex]Mg[/tex] give =[tex]\frac{2}{3}\times 0.005=0.0033moles[/tex] of [tex]Fe[/tex]
Mass of [tex]Fe=moles\times {\text {Molar mass}}=0.0033moles\times 56g/mol=0.187g=0.000187mg[/tex] (1g=1000mg)
Thus 0.000187 mg of iron is produced.
What colors are absorbed Best Buy the plant gizmo
Answer:
Yellow and Green
Explanation:
It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow
Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.
The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.
Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.

Answer:
See answer below
Explanation:
To understand this, we need to make the reaction involved with the given configuration. Configuration R means that the substituents of the molecule, the priority order goes clockwise (From heaviest to lightest) so, if an Sn2 is ocurring in the reaction this means that the nucleophile, which in this case, is the sodium ethoxide will attack the molecule in the opposite side of the leaving group (which is the chlorine).
Also when this occurs, as Sn2 is a bimolecular reaction and is held in one step, it occurs an inversion in the configuration of the product. So, it's the innitial reactant was R, then the final product will be S.

Answer:
2.99 atm
2279.43 torr
44.07 psi
Explanation:
Torr, atms and psi all units are units of pressure.
Conversion from KPa to atm:
1 KPa is equal to 0.00987 atm. To convert from KPa to atm we will multiply the given value with 0.00987 atm.
303.9 KPa × 0.00987 atm / 1 KPa
2.99 atm
Conversion from KPa to torr:
1 KPa is equal to the 7.5006 torr. To convert from KPa to torr we will multiply the KPa value by 7.5006.
303.9 KPa × 7.5006 torr/ 1 KPa
2279.43 torr
Conversion from KPa to psi:
psi is pound per square inch. 1 KPa is equal to the 0.1450 psi. To convert from KPa to psi we will multiply the KPa value by 0.1450 psi.
303.9 KPa × 0.1450 psi / 1 KPa
44.07 psi

Are the forces on the parachutes balanced?
A. The parachutes fall at a constant speed, so the forces are balanced.
B. There is a change in motion, so the forces are balanced.
C. The parachutes fall at a constant speed, so the forces are unbalanced.
D. There is a change in motion, so the forces are unbalanced.
Answer:
When the parachute opens, air resistance becomes much greater than gravity. The forces are no longer balanced and this changes her speed.
Explanation:
Eventually the upward force of the air equals the downward force of gravity. When forces are balanced the speed remains constant.
