Answer:
The properties of carbon dioxide and oxygen are different.
Explanation:
A chemical change is defined as something that changes the substance of something (such as the creation of water from hydrogen and water), and can be figured out if chemical or physical based on different changes and properties. Your answer will be The properties of carbon dioxide and oxygen are different because these are two different elements (compounds in case of CO2) that combine to form a different substance, thus changing the identity of the substance.
Photosynthesis is a chemical reaction that occurs in plants by using radiant energy from sunlight. In this chemical reaction, carbon dioxide from the atmosphere and water from the soil are combined to produce sugar (glucose) that contains stored chemical energy.

A person pushes a 11.5KG lawn mower with an applied force of 70.0N along the 45.0-degree-handle. if the lawn mower moves at a constant velocity
Determine the net force on the mower:
Fnet=__N
Determine the horizontal component of applied force on the mower:
Fx=__N (round to 3 digits)
Determine the horizontal frictional force acting on the mower
Ff=__N (Round to 3 digits)
Calculate the applied force the person must exert on the mower for it to accelerate at a rate of 1.00m/s^2
F=__N (round to 3 digits)
Force is a vector quantity hence it can be resolved into a vertical and a horizontal components.
1) The horizontal component of the applied force is given by;
Fnet = F cos θ
Fnet = 70.0N × cos (45.0)
Fnet = 49.5 N
2) The horizontal component of the frictional force is;
F = -Ff + mgsinθ
F = applied force
Ff =mgsinθ - F
Ff = (11 × 10 × sin 45) - 49.5
Ff = 28.3 N
Horizontal component of Ff
28.3 N cos 45 = 19.9 N
3) The applied force is given by;
F = 11 Kg × 1.00m/s^2 = 11.0 N

a 6.00-kg ornament is held at rest by two light wires that form 30° angles with the vertical, as shown in the figure. an external force of magnitude f acts vertically downward on the ornament. the tension exerted by each of the two wires is denoted by t. a free-body diagram, showing the four forces that act on the box, is shown in the figure. if the magnitude of force f is 410 n, what is the magnitude of the tension t?
The equilibrium condition allows finding the result for the tension of the cable that supports the block is:
The tension is: T₁ = 270.66 N
Newton's second law gives a relationship between force, mass and the acceleration of bodies, when the acceleration is zero it is called the equilibrium condition.
A free-body diagram of the forces is shown in the attachment.
Let's write the equilibrium equation for the vertical axis.
2 [tex]T_1_y[/tex] - f - W = 0
2 [tex]T_1_y[/tex] = W + f
Let's use trigonometry to find the tension, as the angle indicates that it is relative to the vertical.
cos 30 = [tex]\frac{T_1_y}{T_1}[/tex]
[tex]T_1_y[/tex] = T1 cos 30
We substitute.
2T₁ cos 30 = W + f
T₁ = m g + f / 2 cos 30
T₁ = [tex]\frac{6 \ 9.8 + 410}{2 \ cos 30}[/tex]
T₁ = 270.66 N
In conclusion using the equilibrium condition we can find the result for the tension of the cable that supports en bloc is:
The tension is: 270.66 N

A ball is thrown upward with an initial velocity of 22.0 m/s. If
the gravitational acceleration is –9.81 meters per second
squared, what is the maximum height the ball will reach?
Select one:
2.24 m.
24.7 m.
4.48 m.
49.4 m.
The maximum height reached by the ball during the upward motion is 24.7 m.
The given parameters;
initial velocity of the ball, u = 22 m/sThe maximum height reached by the ball is determined using the third kinematic equation as shown below;
v² = u² - 2gh
where;
v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball0 = u² - 2gh
2gh = u²
[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]
Thus, the maximum height reached by the ball during the upward motion is 24.7 m.

How does a balanced chemical equation demonstrate the Law of Conservation of Mass?
Answer:
It shows the same number of atoms of each element on both sides of the equation
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
Explanation:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
A balanced chemical equation shows that total number of atoms before reaction is equal to total number of atoms after the reaction. As, the total mass of any object lies on its atom, a balanced chemical equation demonstrate the Law of Conservation of Mass.
What is Dalton's atomic theory?The Dalton's atomic theory is as follows:
Atoms are the incredibly minuscule building blocks of all stuff.A given element's atoms are all the same size, mass, and other characteristics. Distinct elements' atoms have different mass, size, and other characteristics.Atoms can never be divided, produced, or eliminated.Chemical compounds can be created by combining atoms of various elements in straightforward whole number ratios.Atoms can be joined together, split apart, or altered during chemical processes.The total number of atoms before and after a reaction are equal, according to a chemical equation that is in balance. A balanced chemical equation illustrates the Law of Conservation of Mass since every object's atom holds the entirety of its mass.

Problem 4:
A body fell vertically from the top of a tower. It covered 123.1 m in the final two seconds
before hitting the ground. Determine the height of the tower rounding your answer to the
nearest two decimal places. Let the acceleration due to gravity g=9.8 m/s2.
Answer:
v2^2 - v1^2 = 2 g s fundamental formula
v2 = v1 + 2 g = v1 + 19.8 increase in velocity in 2 sec
v1^2 + 39.6 v1 + 392 - v1^2 = 2 * 9.8 * 123.1 = 2412.76
v1 = (2412.76 - 392) / 39.6 = 51.03
v2 = 51.03 + 19.6 = 70.63
T = 70.63 / .8 = 7.207 sec time to fall height of tower
S = 1/2 g T^2 = 4.9 * 7.207^2 = 254.5 m
(Note v2^2 - v1^2 = 70.63^2 - 51.03^2 = 2385 m
