Explanation:

We use engery too cook our food that's an example of how gases are used.

We run our cars .Cars use oil.

And we use electricity for lights. You need coal for the electricity

A 20.00 ml sample of a solution of sr(oh)2 is titrated to the equivalence point with 40.03 ml of 0.1159 n hcl. what is the molar
goblinko [34]
The   molarity  of Sr(OH)2  solution is  =  0.1159 M

    calculation
write the equation  for reaction
that is,  Sr(OH)2 +2HCl→ SrCl2 + 2 H2O

then finds the mole  of HCl used

moles = molarity x volume 
=40.03 x0.1159 =  4.639 moles

by  use of mole ratio between Sr(OH)2 to  HCL which is 1 :2  the moles of Sr(OH)2  is therefore =  4.639  x1/2 = 2.312  moles

molarity  of  Sr(OH)2  is =  moles  / volume

=2.312 /20 =0.1159 M

How many atoms in the pictured molecule can form hydrogen bonds with water molecules? there is a ball-and-stick model of nh2ch2c
MariettaO [177]
The correct answer would be the third option. There would be two atoms that can form hydrogen bonds with the water molecules from the molecule NH2CH2CH2OH. The atoms O and N could make hydrogen bonds with H. Hydrogen bond is an intermolecular force that is a dipole-dipole interaction between a hydrogen and an atom of O, F and N.

Which pair must represent atoms of the same element?
andrew-mc [135]
Your answer is B and the element is Carbon

So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!

Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!

Definition of the density of the sun?
WARRIOR [948]

Answer:

"The core of the Sun extends from the center to about 20–25% of the solar radius. It has a density of up to 150 g/cm3 (about 150 times the density of water) and a temperature of close to 15.7 million kelvins (K)"
