The answer to you question is

Increasing the external pressure

balandron [24]3 years ago

Water could be made to boil at 105 degrees Celsius instead of 100 degrees Celsius by taking the sample to a higher altitude. Pressure is directly proportional to temperature. So when you bring water into higher altitude, you are increasing the external pressure and therefore increase the boiling point.

What are the phases of matter and the properties of each phase?
inysia [295]

Answer:

The Phases of Matter are Solid, Liquid, and Gas. With Plasma as an exception. Solids are defined by their structural stiffness and resistance to form or volume changes. A liquid is a compressible fluid is one that adapts to the geometry of its container while maintaining a consistent volume regardless of pressure. Gas compresses easily, expands to fill containers, and takes up significantly more space than the liquids or solids from which it is formed. Plasma has no fixed shape or solid volume just like gas. That's the best I can explain, hope you find it helpful!

A compound has a chemical composition of 97.6 g carbon, 4.9 g hydrogen, 52 g oxygen, 45.5 g nitrogen. What is the empirical form
Alekssandra [29.7K]
First  step  is  to  calculate  the  mole  of each   element
that  is;
carbon  97.6/12=8.13moles
hydrogen= 4.9/1=4.9  moles
oxygen 52/16=3.25  moles
nitrogen=45.5/14=3.25 moles

step  two  is  to  calculate  the mole ratio  by   dividing with  the  smallest  number of  moles
that  is  divide  each  mole  with  3.25moles
 carbon=8.13/3.25 =5/2
hydrogen=4.9/3.25= 3/2
oxygen=3.25/3.25=1
nitrogen=3.25/3.25=1
step  3;  multiply  all  the  mole  ratio by  2  to  remove  the  fraction
carbon=5/2  x2 =5
hydrogen=3/2 x2=3
oxygen=1 x2=2
nitrogen  =1x2=2
therefore  the  empirical  formula  is C5H3O2N2(answer c)

#1: A concentration in terms of volume/volume is used to describe which of the following types of solutions?
DanielleElmas [232]
B.
This method of expressing concentration is employed with solutions where both the solute and solvent are liquid. This is because it is easy to measure the volume of a liquid compared to that of a solid. Usually weight/weight is used in concentrations involving only solids.

What is a solution?
Mama L [17]
The correct answer is a solute and a solvent

A solution is any homogenous mixture of two or more substances. It does not necessarily have to be liquid or gaseous.
