B to C:-

  • The temperature remains constant from B to C in any time interval .
  • Looking at the graph there is BC || x axis.
  • Hence temperature remains unchanged.

E to D:-

  • Here also the temperature remains constant.
  • As we can see ED|| x axis

If 250 milliliters of Calcium Hydroxide is titrated with 345 milliliters of 0.75 molarity hydrobromic acid, what is the concentr
Bingel [31]
The balanced neutralization reaction here is:

Ca(OH)2 + 2HBr --> 2H2O + CaBr2

Notice that two moles of Her are required to neutralize every one mole of Ca(OH)2. This means that for however many moles of Her reacted, HALF as many moles of Ca(OH)2 reacted as well.

Moles of HBr reacted = 0.75 M x 0.345 L = 0.259 mol

Moles of Ca(OH)2 reacted = 0.259 mol / 2 = 0.130 mol

Concentration of Ca(OH)2 = 0.130 mol / 0.250 L = 0.52 M

What is the molecular formula of a substance that decomposes into 1.33 g of h and 21.3 g of o, and was found to have a molar mas
Tema [17]
<span>H2O2 First, let's determine how many moles of hydrogen and oxygen atoms we have. Start by looking up the atomic weights of those elements: Atomic weight hydrogen = 1.00794 Atomic weight oxygen = 15.999 Moles hydrogen = 1.33 g / 1.00794 g/mol = 1.319522987 mol Moles oxygen = 21.3 g / 15.999 g/mol = 1.331333208 mol We now have a ratio of 1.319522987 : 1.331333208 and we want a ratio of small integers that is close. Start by dividing all the numbers in the ratio by the smallest value, giving: 1 : 1.008950371 This ratio is acceptably close to 1:1 so I assume the formula is of the form HnOn where n is a small integer. Let's initially assume that n is 1, so the mass would be 1.00794 + 15.999 = 17.00694 Obviously 17 is far smaller than 34.1. So let's divide 34.1 by 17.00694 and see what n should be: 34.1 / 17.00694 = 2.005063815 So the formula we want is H2O2, which is hydrogen peroxide.</span>
