The term for a push or pull is called Force.
Answer:
1.49×10²² atoms of H are contained in the sample
Explanation:
TNT → C₇H₅N₃O₆
1 mol of this has 7 moles of C, 5 moles of H, 3 moles of N and 6 moles of O
Let's determine the mass of TNT.
Molar mass is = 227 g/mol
As 1 mol has (6.02×10²³) NA atoms, how many moles are 8.94×10²¹ atoms.
8.94×10²¹ atoms / NA = 0.0148 moles
So this would be the rule of three to determine the mass of TNT
3 moles of N are in 227 g of compound
0.0148 moles of N are contained in (0.0148 .227) / 3 = 1.12 g
Now we can work with the hydrogen.
227 grams of TNT contain 5 moles of H
1.12 grams of TNT would contain (1.12 .5) / 227 = 0.0247 moles
Finally let's convert this moles to atoms:
0.0247 mol . 6.02×10²³ atoms / 1 mol = 1.49×10²² atoms
Explanation:
k so basically u gotta do 59/1000000 then multiply that by 972 which gives u 0.057348
Answer:
evaporation is most likely to occur on a warm sunny day
Explanation:
Evaporation rates are higher at higher temperatures because as temperature increases, the amount of energy necessary for evaporation decreases. In sunny, warm weather the loss of water by evaporation is greater than in cloudy and cool weather. ... So, sunny, hot, dry, windy conditions produce higher evaporation rates.
Answer:
17 protons, 20 neutrons, and 17 electrons.
Explanation:
A periodic table can be defined as the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.
Generally, a proper representation of the mass number and atomic number of chemical elements is key and very important in chemistry.
Furthermore, as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton).
The mass number of this neutral atom of Cl-37 is 37 and we know that the atomic number (number of protons) of chlorine is 17. Also, the atomic number of an element is equal to the number of its electrons.
A neutral atom of Cl-37 has 17 protons, 20 neutrons, and 17 electrons.
Hence, a neutral atom of Cl-37 can be identified based on its number of protons because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.
