Answer: 0.0508mL
Explanation: Using the basic formula that states: C acid * V acid = C base * V base. we have:0.568 * 17.88 = 20 * C base.
therefore concentration of the base is 1.0156/20 = 0.0508 mL
It is going through a physical change
The correct answer to this is:
<span>Chondroitin sulfate is abundant in the matrix of <u>“Cartilage”.</u></span>
<span>A 1 unit of Chondroitin sulfate has a chemical formula of
C</span>13H21NO15<span>S. It is
usually found attached to proteins as part of a proteoglycan and is a vital
structure of cartilage by providing much resistance to compression. Due to
this, this chemical has found wide use as a dietary supplement for treatment of
osteoarthritis.</span>
Answer:
kJ
Explanation:
The thermochemical equation for decomposition of ammonium nitrate is:


Given mass= 50.0 kg =
(1kg=1000g)

According to stoichiometry:
1 mole of
gives = 82.1 kJ of heat
Thus
of
give =
kJ of heat
Thus
kJ of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate.
The soup water would turn into soap.
