(37 is a superscript come the left of the symbol, and also 17 is a subscript to the left of the symbol)
1) Chlorine-37 is the chlorine isotope with mass number 37.
You are watching: Chlorine 37 can be represented as
2) The atomic mass of chlorine is 17. Every the atoms of chlorine have actually the exact same atomic number (all the atoms of an facet have the very same atomic number). You find this number in a periodic table.
3) The isotope representation consists of:
i) The prize of the facet (Cl in this case) in ~ the facility of the representation.
ii) The mass number (37) together a superscript come the left of the symbol. The is:
iii) The atom number (17) together a subscript to the left that the symbol. That completes the representation in this form:

Measurements present that the enthalpy the a mixture of gas reactants rises by 215. KJ during a certain chemical reaction, w
yellowcomic.com: The change in power of the gas mixture during the reaction is 60 kJ. The reaction is endothermic.
According to an initial law the thermodynamics:
q = heat took in or released
w = job-related done or by the system
w = work done top top the mechanism
w = -155 kJ
q = +215kJ Heat absorbed by the system is positive
As the warm is soaked up and enthalpy increases, the reaction is endothermic.

Gelatin has actually a thickness of 1.27 g/cm³. If you have a blob that gelatin dessert the fills a 2.0 liter bottle, what is that mass?
yellowcomic.com : alternative A) 2540 g
Here, the thickness of the gelatin is recognized to be together 1.27
And the volume 2.0 liter
Here, 2 liters = 2
Using, the formula for density;
ρ = density;
m =mass and v=volume.

Substituting the values given; ρ = 1.27
m = to it is in found and also v = 2000
m = 2540 g
Therefore, the mass will certainly be 2540 g

Consider the scenario.
A scientific design that provides a computer program come predict volcano eruption is a mathematical model.
A model is an abstraction the the genuine world. They aid to recognize a far-ranging part the the genuine world.Computer deserve to be programmed to give specific predictions. Computation powers of a computer are offered in this procedure. Humans have boundaries to which they deserve to compute mathematics expressions. Instead, they space taken in by a computer in kind of programs. This is a mathematical model run by a computer using a set of instruction called programs.
