Answer: The number of protons in given isotope are 92.
Explanation:
The general representation of an isotope is given as
where,
Z = atomic number
A = atomic mass
X = symbol of an element
We are given:
Isotope =
Atomic number is defined as the number of protons or number of electrons present in an element. Here atomic number is 92.
Thus, Number of protons in given isotope of uranium = 92
Answer:
The number of protons is 92.
Explanation:
Hello! Let's solve this!
This is the way to write an isotope
Z: represents the atomic number
A: represents the mass number
X: is the element
The number of protons is equal to the atomic number.
In this case A=235
Z=92
X=U
We conclude that in this case the atomic number is 92, so the number of protons is 92.
an idea that has been changed due to new information
O a general agreement among scientists about a scientific idea
the understanding that knowledge in a particular area can be uncertain
The scientific consensus is a general agreement among scientists about a scientific idea. The correct option is C.
A scientific idea is the explanation or facts of science. It reveals the truth about the world. How the world works and the secrets of nature. It tells and gathers true information about the world.
The different aspects of life and the world are understood and studied by scientists. Different scientists work for different forms of life. The scientist's ideas change over the different evidence.
The generalized ideas of various scientists give and agree upon the different theories of the levels of science. The publication process and specialized field.
Thus, the correct option is C. a general agreement among scientists about a scientific idea.

Answer:
Condensation is the change of state from a gas to a liquid
Answer:
1.2433 *10^23 carbon atoms
Explanation:
First you need to calculate the grams of the empirical formula.
C4H10
Carbon = 12.01 g x 4
Hydrogen = 1.008 x 10
Sum those together to get = 58.12 g
Divide the 3.00g by the total g in the compound.
3.00/58.12 = 0.0516
Then times 0.0516 by the number of carbon atoms
0.0516 x 4 = .20646
Then multiple by Avogadro's number
.20646 x 6.022x10^23 = 1.2433x10^23
Rounded to 1.24x10^23 carbon atoms
of carbon is present in 4.00 g of butane.
Further Explanation:
The number of atoms or molecules that can be present in one mole of any substance is determined by a number, known as Avogadro’s number. The numerical value of Avogadro’s number is . Such units can either be atoms or molecules.
The formula to calculate the moles of is as follows:
…… (1)
The given mass of butane is 4.00 g.
The molar mass of butane is
Incorporate these values in equation (1).
The number of molecules present in one mole of butane is . So the expression to calculate the number of molecules of butane is as follows:
…… (2)
The number of moles of butane is 0.0688 mol.
The value of Avogadro’s number is .
Incorporate these values in equation (2).
A molecule of butane consists of four carbon atoms in it. So the number of carbon atoms can be calculated as follows:
