What are some substances that make up water?
Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states.
How many protons are in a pizza?
According to LiveStrong, a typical slice of thin-crust cheese pizza contains 230 calories while a slice of thick-crust cheese pizza contains 312 calories.
What particles make up an atom gizmo?
Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Element Builder Gizmo ™ shows an atom with a single proton. The proton is located in the center of the atom, called the nucleus.
What is the Lewis structure of water?
The Lewis structure of water shows that the oxygen atom has two lone pairs. Those lone pairs, together with the large difference in electronegativity between oxygen and hydrogen, give water one of its most important properties, its strong polarity.
Why is water called water?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (” water “; “wet”).
How much sodium is in a slice of cheese pizza?
A slice of pizza can weigh in anywhere from 600 to 1500 mg of sodium per slice!
How much sodium is in a cheese pizza?
|Amount Per Serving||% Daily Value *|
|Sodium (mg)||630||26 %|
|Total Carbohydrate (g)||42||14 %|
|Dietary Fiber (g)||2||8 %|
Does cheese pizza have protein?
Depending on the brand, a single-serving grocery-store cheese pizza made with an enriched-flour crust provides about 13 grams of protein, while one slice of cheese pizza (about 4 ounces) has 12 grams of protein. School lunch cheese pizza made with a whole-grain crust provides about 22 grams of protein per serving.
What is the heaviest stable isotope?
Examples of elements with doubly magic nuclei are 42He, with 2 protons and 2 neutrons, and 20882Pb, with 82 protons and 126 neutrons, which is the heaviest known stable isotope of any element.
What are electrically charged particles called?
Many fundamental, or subatomic, particles of matter have the property of electric charge. For example, electrons have negative charge and protons have positive charge, but neutrons have zero charge.
Which radioisotope is most stable?
A good example of this is tritium, a radioactive isotope of hydrogen naturally present at extremely low levels. This table contains the elements that have no stable isotopes. Radioactive Elements.
|Element||Most Stable Isotope||Half-life of Most Stable Isotope|
What is the correct structure for oxygen?
Each O is surrounded by four dots and two sticks or lines, representing another 4 electrons in the O2 double bond. So each O is surrounded by 8 total valence electrons, giving it an octet and making it stable. The two letter O’s in the O2 Lewis structure represent the nuclei (centers) of the oxygen atoms.
What is the Lewis structure of C2H4?
For C2H4. In C2H4, if we look into the lewis structure, we will see that there are three bonded pairs of electrons around each carbon and zero lone pair. According to the VSEPR chart, the shape of the ethene molecule is trigonal planar. There are two triangles overlapping each other as we can see in the diagram.
What is the Lewis structure of XeF4?
The Lewis structure for XeF4 has a total of 36 valence electrons. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell). We also need to check to make sure we only used the number of available valence electrons we calculated earlier (no more, no less).
