Sodium atoms combine with chlorine atoms to form sodium chloride (table salt). Which part of Dalton’s atomic theory explains why

table salt can be made? Everything is made from atoms and atoms are the smallest unit of matter that can’t be broken down into anything else. Atoms can react together, be separated from each other, or be rearranged via chemical reactions. Atomic nuclei can react in nuclear reactions, which turn matter into energy. Atoms of one element are all the same and are fundamentally different from atoms of other elements.

What is the mole fraction of potassium dichromate, K2Cr2O7, in a solution prepared from 24.42 g of potassium dichromate and 240.
Harrizon [31]

Answer:

6.19\times 10^{-3} is the mole fraction of potassium dichromate.

Explanation:

Mass of potassium dichromate = 24.42 g

Moles of  potassium dichromate =n_1=\frac{24.42 g}{294.185 g/mol}=0.0830 mol

Mass of water = 240.0 g

Moles of water =n_2=\frac{240.0 g}{18.015 g/mol}=13.3222 mol

Mole fraction is calculated by:

\chi_1=\frac{n_1}{n_1+n_2}

\chi_1=\frac{0.0830 mol}{0.0830 mol+13.3222 mol}=0.00619=6.19\times 10^{-3}

6.19\times 10^{-3} is the mole fraction of potassium dichromate.

This what happen when climate changes
zysi [14]

if you are talking about the climate change of today as in the heat your answer would be ,because the green house gases are trapping in the heat and reflecting it back down it disrupts the temperature everywhere. so the hot weather will become even HOTTER the cold weather will become warmer of come to late ,and the places such as Greenland and Antarctica which are covered in snow will start to melt making the whole globe more hot year by year
