Describe characteristics and identify oxidation-reduction(redox) reactions.
plz and thx
Answer:
I hope This helps
Explanation:
The majority of oxidation-reduction (redox) reactions share two critical features. One is that a reduction happens in both, while equivalent oxidation occurs; they are combined.
The oxidation - reduction (redox) reactions has the characteristics of changes in oxygen, hydrogen and electrons.
What are the characteristics and identify oxidation - reduction (redox) reactions?Oxidation is the process during the reaction the reactant loses the electron. Reduction is the process during the reaction, the reactant gains the electron.
Redox reaction can be identified by knowing the number of oxidation. It can also be known through the atoms in this process should be bonded as ionic. During the reaction, the increase in oxidation number can be said as oxidation.
The different types of redox reactions are:
Decomposition reactionDisproportion reactionCombination reactionDisplacement reactionThese are the important characteristics of oxidation and reduction (redox) reactions.

(Fill in the blanks)For every force there is one that is_____in size but _________in direction.
Answer: For every force there is a reaction force that is equal in size, but opposite in direction.
Hope it helps:)
For every force, there are 2 components one that is equal in size but opposite in direction.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

In one paragraph, using your own words, explain how Earth's atmosphere is able to protect you against the harmful radiation that is emitted from the sun. Be sure to use proper spelling, grammar, and punctuation.
Answer: Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun's heat is radiated back into space. The ozone layer shields us from the harmful effects of excessive UV radiation, which can lead to sunburn, skin cancer and eye damage.

Plants give off oxygen as part of photosynthesis. Explain the impact of this process on humans.
Answer:
Humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.
The process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.
The given problem is based on the process of photosynthesis and the effect of photosynthesis on humans.
The photosynthesis is the process by which the green plants and other organisms utilize the sunlight to prepare nutrients from carbon dioxide and water.Photosynthesis in plants involve the green pigment known as Chlorophyll, which is responsible for the production of oxygen into the atmosphere.And humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.Thus, we can conclude that the process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.

Write a discussion post that contains the following:
Information about the magnetic field from the three websites you used.
What each author believes about the magnetic field.
What you believe about the magnetic field.
Citations for your three websites.
Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2Explanation:
