What are the strongest and weakest bonds?

What are the strongest and weakest bonds? This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” What is […]

How many light years can we travel?

How many light years can we travel? Even if the fabric of space didn’t change over time, there are plenty of objects we can see today that could be farther away than 13.8 billion light-years. The only catch is that their light could travel for 13.8 billion light-years at most; how the objects move after […]

Who Solved the 2 body problem?

Who Solved the 2 body problem? The two-body problem consists of determining the motion of two gravitationally interacting bodies with given masses and initial velocities. The problem was first solved by Isaac Newton in 1687 using geometric arguments. How do you deal with two-body problems? How to Deal with the Two-body Problem Ask support from […]

What tells the cells what to do?

What tells the cells what to do? Hidden inside almost every cell in your body is a chemical called DNA. A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Do cells know they are alive? Cells don’t ‘know’ what to do – they […]

How accurate is Gaia?

How accurate is Gaia? Even stars near the Galactic Centre, some 30 000 light-years away, will have their distances measured to within an accuracy of 20%. – The Gaia Data Processing and Analysis Consortium (DPAC) consists of more than 400 individuals who will contribute some 2000 person-years of effort to the Gaia data processing exercise. […]

Why the tip of Allpin made sharp?

Why the tip of Allpin made sharp? The tip of an allpin is made sharp so that large pressure is exerted at the sharp end and it can be driven into with less effort. What are the two factors which does not change the vertical height of mercury column above the free surface? The density […]

Why do we not see the other side of the moon?

Why do we not see the other side of the moon? We don’t see the far side because “the moon is tidally locked to the Earth,” said John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project. If the moon were a perfect sphere, then the gravity felt on the far side and the […]

Is salt the solvent in a saltwater solution? In a saltwater solution, salt is the solute and water is the solvent. What is the solvent in a salt water solution? In a NaCl solution (salt-water), the solvent is water. A solute is the component in a solution in the lesser amount. In a NaCl solution, […]

Which sublevel is the lowest in energy?

Which sublevel is the lowest in energy? 1s Does the 3f sublevel exist? Does the 3f sublevel exist? (Note: the “3” stands for the 3rd energy level.) No, in the 3rd energy level there are only s, p, and d sublevels. The following sublevels exist in the 3rd energy level: 3s, 3p, and 3d. How […]
