Watch complete video answer for “Total number of stars present in universe is” of Biology Class 12th. Get FREE solutions to all questions from chapter EVOLUTION.
To explain why the total energy in the universe consists of 5% of the normal matter (matter consisting of atoms), 27% of the dark matter, and 68% of the dark energy.SOLUTION: In the field of the big bang, 4.559×10atoms were produced. The dark energy is the energy of black holes....
“A higher percentage of the total matter in the universe would result in more clusters being formed,” says Anatoly Klypin from theUniversity of Virginia. “But it is difficult to measure the mass of any galaxy cluster accurately as most of the matter is dark, and we cannot...
pH, pH scale - (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than...
Atom is the smallest unit of matter found in our Universe. A molecule is formed by more than a single atom. As an example, a water molecule consists of a single oxygen atom and two hydrogen atoms.Answer and Explanation: Identify the given information in the problem: Given ...
Step 3: Calculate the total number of electrons in one molecule of methaneIn one molecule of methane (CH₄):- There is 1 carbon atom contributing 6 electrons.- There are 4 hydrogen atoms contributing a total of 4×1=4 electrons. Now, we can calculate the total number of electrons in ...

The universe has more platinum atoms than silver atoms? Platinum is the pricier metal because on earth it is much rarer than silver because billions of years ago much of the platinum and gold sank out of the earth's crust and into its core. There is an estimated 6 times more platinum th...
If the future development of quantum theory happens to turn in that direction, we could conceive the beginning of the universe in the form of a unique atom, the atomic weight of which is the total mass of the universe. This highly unstable atom would divide in smaller and smaller atoms by...
Examples of the use of other vinyllithiums β-functionalized with other atoms can be found in the total synthesis of the antifungal agent papulacandin D, where (E)-β-trimethylsilylvinyllithium (155), generated by tin/lithium transmetalation from (E)-1-(tri-n-butylstannyl)-2-(trimethylsilyl...
