Taking into account the definition of net ionic equation, the net ionic equation is Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) and H⁺ and NO₃⁻ are the spectator ions.
The net ionic equation is a chemical equation for a reaction that lists only the species that participate in the reaction.
In other words, an ionic equation is a chemical equation where electrolytes in aqueous solution are written as dissociated ions. Usually this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation, to indicate that they are in aqueous solution.
The balanced equation will be:
Sr(NO₃)₂ (aq) + H₂SO₄ (aq) → SrSO₄ (s) + 2 HNO₃ (aq)
where (aq) means aqueous and (s) solid.
Taking into account that:
All salts of NO₃⁻, C₂H₃O₂⁻, ClO₃⁻ and ClO₄⁻ are soluble.The total ionic equation in separated aqueous solution will be:
Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 H⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) + 2 NO₃⁻(aq) + 2 H⁺(aq)
A spectator ion is an ion that appears both as a reactant and as a product in an ionic equation.
Spectator ions can be either cations (positively charged ions) or anions (negatively charged ions).
When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.
In this case, H⁺ and NO₃⁻ are the spectator ions because they appear unchanged in both the product and the reagent. So these ions cancel out by writing the net ionic equation and you get:
Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s)
In summary, the net ionic equation is Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) and H⁺ and NO₃⁻ are the spectator ions.

Based on their electrons dot diagrams, what is the formula for the covalently bonded compound
of nitrogen and hydrogen?
Answer:
Nitrogen, the next nonmetal, has 5 electrons in the valence shell, so it needs to combine with 3 hydrogen atoms to fulfill the octet rule and form a stable compound called ammonia (NH3).
The covalent compound formed from nitrogen and hydrogen is called ammonia with the formula NH₃. Each hydrogen shares its valence electron with three valence electrons of nitrogen.
What is ammonia?Ammonia, NH₃ is a covalent compound formed by the combination of nitrogen and three hydrogen atoms. Nitrogen is a highly electronegative element with 5 valence electrons.
Nitrogen needs 3 more electrons to achieve octet. Hence valency of nitrogen is 3. During chemical bonding it gains three electrons though sharing or donation from metals.
Hydrogen needs one more electron to be stable. Hence, nitrogen shares its three valence electrons each with three hydrogens and each hydrogen in turn shares its one valence electron with nitrogen forming NH₃.

Why is fusion not used to generate electrical power?
Answer:
One of the biggest reasons why we haven't been able to harness power from fusion is that its energy requirements are unbelievably, terribly high. In order for fusion to occur, you need a temperature of at least 100,000,000 degrees Celsius. That's slightly more than 6 times the temperature of the Sun's core.
Explanation:
Answer:
The energy requirements for fusion is too high to be used to generate electrical power.

Answer: It's a modern-day engineering challenge to remove human-made contaminants from
drinking water. After a quick review of the treatment processes that municipal water
goes through before it comes from the tap you will learn about the still-present
measurable contamination of drinking water due to anthropogenic (human-made)
chemicals. Substances such as prescription medication, pesticides and hormones are
detected in the drinking water supplies of American and European metropolitan cities.
The engineering design process can be used to design solutions for a real-world
problem (contaminated water) that could affect health.
Engineering Connection
The water that comes from our faucets has passed through a complex system designed
by many different types of engineers. Civil, chemical, electrical, environmental,
geotechnical, hydraulic, structural and architectural engineers all play roles in the
design, development and implementation of municipalities' drinking water supplies and
delivery systems. Hydraulic engineers design systems that safely filter the water at a
rate needed to supply a specific region and population. Chemical engineers precisely
determine the amounts and types of chemicals added to source water for coagulation
and decontamination to make the water safe to drink and not taste bad. Even so,
modern pharmaceutical and agricultural practices persist in contaminating our water
supplies.

Water and some other molecules exhibit a property know as hydrogen bonding. A hydrogen atom in one molecule of water is attracted to the oxygen in a neighboring molecules of water.'
The force of this attraction is less than a standard chemical attractive force, but it is real and measurable.
When billions and trillions of water molecules are held together by this force, the small amount of molecule to molecule force is added up to a tremendous force. That is why even though sulfur is below oxygen on the periodic table, hydrogen sulfide is a gas while hydrogen oxide is a liquid at room temperature.
Hydrogen bonding explains the unique properties of ice, liquid water and steam,We all know water exists in several forms such as solid, liquid and ice. Water boils at 100 C and freezes at 32 F, right? Am I correct? Let us look at some of the chemistry behind forms of water.
The strong polar bond between water molecules creates water cohesion.
As they are cooled, aggregates of most other substances increase monotonically in density becoming progressively heavier -- the colder they are, the more tightly packed their molecules become. But water possesses a peculiar physical feature: ice expands, so it is lighter than liquid water (i. e., ice floats). When water trapped in rock crevices freezes, it breaks rocks (and pipes).
Water is vital to all known life forms, that is, all those on planet Earth. It is so integral to life as we know it that many biologists cannot even envision life without water (although that might be possible). Indeed, the physical properties of water dictate critical thermal limits for living systems.
In one sci-fi story, an alien refers to humans as "ugly bags of mostly water" -- our bodies are about 60-70% water, depending upon how dehydrated we are at any given time. Humans use massive amounts of freshwater to drink, cook, bathe, flush toilets, do laundry, fill swimming pools, irrigate yards and gardens, run flowing fountains, and for recreation. Precious clean water is often wasted, such as when people leave tap water running while washing their hands or brushing their teeth. The personal water consumption of an average American is about 200 gallons per day, but when industrial and energy usage is added in, per capita freshwater usage is more than 2000 gallons/day. People in third world countries use much less water, of course.
Most freshwater is claimed or "owned" and there is not enough to go around. Approximately half of the world's population of people do not even have adequate access to clean drinking water. One of the major symptoms of the human overpopulation crisis is shortages of available fresh water. Wars will be fought over water.
Hydrogen bonding is a property of water and some other molecules. A hydrogen atom in one water molecule is attracted to an oxygen atom in another water molecule.
What is a matter?Matter is a substance composed of various particle types that occupies physical space and has inertia.
According to modern physics principles, each type of particle has a distinct mass and size. The electron, proton, and neutron are the most well-known examples of material particles.
Atoms and molecules are tiny particles that make up solids, liquids, and gases.
This attraction has a lower force than a standard chemical attractive force, but it is real and measurable.
When this force holds billions and trillions of water molecules together, the small amount of molecule to molecule force adds up to a tremendous force.
Thus, due to these bonds, the water does not seem to behave like sand.
