So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas
no need to show work i am a teacher at a college
Answer:
2672 kj
Explanation:
C4H10 O mole wt = 48 + 10 + 16 =~ 74 gm
27200 gm / 74 gm/mole = 367.57 moles
367.57 moles * 7.27 kj/mole =
Explanation:
Y has 13 protons and we know that Aluminium (Al) too has 13 protons.
So , element Y = Aluminium
• In an element , no. of protons = no. of electrons. So , Y has 13 electrons.
• Mass no. of Y (Aluminium) = 27.
• Also we know that ,
Mass number = no. of protons + no. of neutrons
So,
No. of neutrons = 27 - 13 = 14
• Valence electrons are the electrons which are present in the outermost shell of an element.
Electronic Configuration of Y = 2,8,3
So, Y has 3 valence electrons.
• We know that Y is Aluminium & Aluminium is a metal. So , Y is a metal.
• Valency of Y = +3
HA and HB are present in concentrations of 0.182 M and 0.153 M, respectively.
<h3>What kind of acids are monoprotic?</h3>
Monoprotic acids include benzoic acid (C6H5CO2H), acetic acid (CH3CO2H or HOAc), nitric acid (HNO3), and hydrochloric acid (HCl).
<h3>How can you tell if a substance is monoprotic?</h3>
Any acid with only one hydrogen atom in its formula is called a monoprotic acid, while some acids with multiple hydrogen atoms may also fall under this category. In other words, while all monoprotic acids contain only one hydrogen, not all single-hydrogen acids are monoprotic.
<h3>Do monoprotic acids have a low acidity?</h3>
Because it easily loses its hydrogen ion in solution, the monoprotic acid HBr is regarded as being strong.
