What is responsible for the unusual chemical properties of water?

I'd schedule the picnic a bit earlier than originally planed. I'd do this because everyone can be home by the time the rain starts.

If you don't want to do that do /weather clear and no more rain.

There will be 10 oxygens on the products side and 2 on the reactants so to balance these out, we multiply the 02 on the reactants side by 5. The final equation will be C3H8 + 502 ----> 3CO2 + 4H20.

Answer:

Atomic orbital energy ordering.

Explanation:

The transition metals constitute the d-block. The answer to your question has to do with the energy ordering of atomic orbitals. Specifically, the 3s orbitals are lower in energy than 3p, which are lower in energy than 4s, which are lower in energy than 3d (remember the principal quantum number for d orbitals is one minus the principle quantum number of the shell so n = 4 level's d orbitals are the 3d orbitals). According to the Aufbau principle, atomic orbitals are filled with electrons from the lowest energy up. So the orbitals would have to be filled in the order of 3s, 3p, 4s, and then 3d. Magnesium has its last valence electron residing in the 3s orbital and Aluminum has its last valence electron residing in the first 3p orbital (specifically the 3px orbital, which is aligned horizontally in the 3d plane. The three p orbitals for all principle quantum levels are px, py, pz, with the x, y, z describing the orientation in the 3d plane). The 3d has not yet been reached in terms of energy ordering. This is why there are no transition elements between magnesium and aluminum, in terms of electronic structure.

Answer:

94.155 Moles

Explanation:

Since you are given atoms, to get to moles you need to use the formula I used below. Pretty simple, just plug and chug. Work can be found below.

Hope this helps! :^)

94. 125 moles are present in 5.67x10^25 atoms of Carbon (C).

The mole is a unit of measurement that is comparable to well-known units like pair, dozen, bulk, etc. It offers a precise count of atoms or molecules in a large sample of materials.

The amount of substance that has the same number of discrete entities (atoms, molecules, ions, etc.) as the number of atoms in a sample of pure 12C weighing exactly 12 g is known as a mole.

The word "mole" has a "big mass" or "bulk" sense in Latin, which is congruent with its use as the name for this unit. The mole establishes a connection between bulk mass, which is a simple macroscopic attribute to measure, and the number of atoms, molecules, and other fundamental units, which is a crucial fundamental property.

Therefore, 94. 125 moles are present in 5.67x10^25 atoms of Carbon

(C).

Answer:

B

Explanation:

Nonmetals have nearly full valence shells and try very hard to get that last few electrons to complete their valence shell. This allows them to achieve noble gas stability. This is why they have high electronegativities and electron affinities.

Answer:

When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

Answer:

Negative

Answer:

By using the criss cross method,the -1 charge of nitrate ion is shifted to ammonium ion and +1 charge of ammonium ion is shifted to nitrate ion. In this way, the final formula NH4NO3 is formed for the ammonium nitrate.

Answer(s):

Atomic model

Bohr's greatest contribution to modern physics was the atomic model. The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons.  

Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.

The chemical element bohrium (Bh), No. 107 on the periodic table of elements, is named for him.

Liquid droplet theory

Bohr's theoretical work contributed significantly to scientists' understanding of nuclear fission. According to his liquid droplet theory, a liquid drop provides an accurate representation of an atom's nucleus.

This theory was instrumental in the first attempts to split uranium atoms in the 1930s, an important step in the development of the atomic bomb.

Despite his contributions to the U.S. Atomic Energy Project during World War II, Bohr was an outspoken advocate for the peaceful application of atomic physics.

Quantum theory

Bohr's concept of complementarity, which he wrote about in a number of essays between 1933 and 1962, states that an electron can be viewed in two ways, either as a particle or as a wave, but never both at the same time.

This concept, which forms the basis of early quantum theory, also explains that regardless of how one views an electron, all understanding of its properties must be rooted in empirical measurement. Bohr's theory stresses the point that an experiment's results are deeply affected by the measurement tools used to carry them out.

Bohr's contributions to the study of quantum mechanics are forever memorialized at the Institute for Theoretical Physics at Copenhagen University, which he helped found in 1920 and headed until his death in 1962. It has since been renamed the Niels Bohr Institute in his honor.

Explanation:

Niels Bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his Nobel Prize-winning research on the structure of atoms.

Born in Copenhagen in 1885 to well-educated parents, Bohr became interested in physics at a young age. He studied the subject throughout his undergraduate and graduate years and earned a doctorate in physics in 1911 from Copenhagen University.

While still a student, Bohr won a contest put on by the Academy of Sciences in Copenhagen for his investigation into the measurements of liquid surface tension using oscillating fluid jets. Working in the laboratory of his father (a renowned physiologist), Bohr conducted several experiments and even made his own glass test tubes.  

Bohr went above and beyond the current theory of liquid surface tension by taking into account the viscosity of the water as well as incorporating finite amplitudes rather than infinitesimal ones. He submitted his essay at the last minute, winning first place and a gold medal. He improved upon these ideas and sent them to the Royal Society in London, who published them in the journal Philosophical Transactions of the Royal Society in 1908, according to Nobelprize.org.  

His subsequent work became increasingly theoretical. It was while conducting research for his doctoral thesis on the electron theory of metals that Bohr first came across Max Planck's early quantum theory, which described energy as tiny particles, or quanta.

In 1912, Bohr was working for the Nobel laureate J.J. Thompson in England when he was introduced to Ernest Rutherford, whose discovery of the nucleus and development of an atomic model had earned him a Nobel Prize in chemistry in 1908. Under Rutherford's tutelage, Bohr began studying the properties of atoms.

Bohr held a lectureship in physics at Copenhagen University from 1913 to 1914 and went on to hold a similar position at Victoria University in Manchester from 1914 to 1916. He went back to Copenhagen University in 1916 to become a professor of theoretical physics. In 1920, he was appointed the head of the Institute for Theoretical Physics.

Answer:

Explanation:

Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.

Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.

NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.

Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.

All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.
