Water is formed via covalent bonding of hydrogen and oxygen atoms, demonstrating the principle of elements joining to fill their valence shells. This process is a representation of a simple chemical reaction, following the law of conservation of matter.
Explanation:Water molecules, formed by the combination of hydrogen and oxygen atoms, are an excellent example of covalent bonding.
The ratio of hydrogen to oxygen in water is 2:1, giving us the well-known formula H2O. Both hydrogen and oxygen atoms share electrons to fill their outer shells, making them more stable.Atoms of any element tend to join with atoms of other elements in systematic ways to form various compounds. For instance, other than water, we have the carbon-hydrogen combination resulting in methane (CH4). This is dictated by the requirement of elements to fill their valence shells.The reaction of hydrogen and oxygen to form water is a simple but vital chemical reaction occurring in nature. It exemplifies the fundamental principle of a balanced chemical equation, adhering to the law of conservation of matter where the total number of atoms remains the same before and after the reaction.Learn more about Covalent Bonding here:https://brainly.com/question/19382448

what is friction. what does friction do as an ice skater slide across the ice?
Friction is a force that opposes motion between surfaces in contact. When an ice skater slides across the ice, friction between the skates and the ice slows them down and eventually brings them to a stop.
Explanation:Friction is a force that opposes relative motion between surfaces in contact. When an ice skater slides across the ice, friction between the skates and the ice slows down the skater and eventually brings them to a stop. The ice skates exert a force on the ice, and the ice exerts an equal and opposite force on the skates, creating friction.

Explain how the first three steps of scientific inquiry are related.
Answer:
Explanation:
The scientific inquiry is a fact finding inquiry for determining the cause or occurrence of the natural processes, events or phenomena. The three steps of the scientific inquiry are related such a making a background research for the desired topic, observation of the natural process, and making hypothesis based on the observation. These three steps are basic for conducting a research and for finding the facts associated with the research.

Which BEST describes the difference between speed and velocity?
A) Velocity is instantaneous.
B) Speed is a vector quantity.
C) Speed includes rate of change and direction.
D) Velocity includes rate of change and direction.
Answer : The correct option is, (D) Velocity includes rate of change and direction.
Explanation :
Speed : Speed is defined as the distance traveled by an object with respect to the time taken. It is a scalar quantity that means it tell us about the magnitude of an object not direction.
Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only.
Hence, the correct option is, (D) Velocity includes rate of change and direction.
Speed is a scalar quantity that only considers the magnitude of movement, while velocity is a vector quantity that includes both the magnitude and direction of movement.
Explanation:D) Velocity includes rate of change and direction.
Speed and velocity are both terms used to describe how fast an object is moving. However, there is a key difference between the two. Speed is a scalar quantity, meaning it only considers the magnitude or size of the movement. Velocity, on the other hand, is a vector quantity. This means it includes both the magnitude and direction of the movement.
For example, if a car is traveling at a speed of 60 miles per hour, that only tells us how fast it is going. However, if we say the car is traveling at a velocity of 60 miles per hour northeast, that tells us both the speed and the direction.

compare the life cycles of flower less seed plant and flowering seed plants
The life cycles of gymnosperms and angiosperms include seed germination and development stages; however, angiosperms are unique in their production of flowers and fruit-enclosed seeds, which distinguishes them from gymnosperms with exposed seeds on cones.
The life cycles of both non-flowering seed plants, like gymnosperms, and flowering seed plants, known as angiosperms, are characterized by a sequence of developmental stages from seed germination to the production of new seeds. However, there are fundamental differences between these two groups of plants. In the life cycle of a gymnosperm, seeds are not enclosed within a fruit but are often found on the scales of cones. In contrast, angiosperms produce seeds within a fruit, which develops from the flower.
The flower is the reproductive structure that typically includes petals, stamens, pistils, and is responsible for the sexual reproduction of these plants. Angiosperms are divided into two main groups: monocots and dicots. Basal angiosperms differ from other flowering plants in having traits that are more ancestral or less derived. The life cycle of an angiosperm involves alternating generations, with the sporophyte phase being the dominant generation.
The process of seed development in angiosperms is often characterized by the acronym RRAPP, signifying Reduction of the gametophyte, Retention of the gametophyte within the tissues of the parent plant, Arrested development of the seed until favorable conditions, Provisioning of the embryo with nutritive tissue, and Packaging of the seed with a protective coat.
Summarily, the distinctive flower structure and the protected seed development are key differentiators of angiosperms when compared with gymnosperms. Both life cycles show reduction in the haploid stage and growing complexity over time, but angiosperms have advanced further by incorporating flowers and encased seeds into their reproductive strategy.

Classify Use periodic table to classify the elements potassium (K) ,Bromine (Br) and argon, (Ar) according to know likely their atoms are to do the following
A-Lose electrons to form positive ions
B-Gain electrons to form negative ions
C-Neither gain or lose electrons
Potassium is likely to lose electrons to form positive ions, Bromine is likely to gain electrons to form negative ions, and Argon is neither likely to gain or lose electrons.
Explanation:Potassium (K) is in Group 1 of the periodic table, which means it has one valence electron. It is highly likely to lose this electron to form a positive ion (K+).
Bromine (Br) is in Group 17, so it has seven valence electrons. It is highly likely to gain one electron to complete its octet and form a negative ion (Br-).
Argon (Ar) is in Group 18, a group of noble gases that have a full octet of valence electrons. These elements are stable and generally do not gain or lose electrons.

Amy has a mass of 30 kg, and she is riding a skateboard traveling 5 m/s. What is her momentum
The momentum of Amy of mass 30 kg travelling at a speed of 5 m/s is 150 Kg m/s²
What is momentum?
Momentum is defined as the product of mass and velocity of a body. Mathematically, we can write vector as -
p = mv
It is a vector quantity. In a three dimensional coordinate, the momentum vector can be resolved as -
[p] = p[x] a[x] + p[y] a[y] + p[z] a[z]
[p] = m {v[x] a[x] + v[y] a[y] + v[z] a[z]}
Given is Amy of mass 30 kg and she is riding a skateboard traveling 5 m/s.
Mass of Amy = [m] = 30 Kg
Velocity of Amy = [v] = 5 m/s
Now, the momentum of Amy will be -
p[A] = mv = 30 x 5 = 150 Kg m/s²
Therefore, the momentum of Amy of mass 30 kg travelling at a speed of 5 m/s is 150 Kg m/s²
