Answers

Answer 1

Answer:

Eleanor wants to show her class a comparison of melting rates between two different solids when heat is applied. A graph would be more suitable than a table to show her data because the she can see the trend line of the effects of melting than the table.

show me the steps for solving this problem how many grams of O2 are required to burn 46.0 grams of C5H12

Answers

(MM)C5H12=5x12+12x1=72g/mol
(MM)O2=2x16=32g/mol
Acoording to equation:
C5H12 + 8O2 => 5CO2 + 6H2O

The proportion between C5H12 and O2 is 1:8 in mol

So: 72/16=46/x finale x=10,2g of O2

Of the choices below, which is true for the relationship shown? a. It is Ka for the acid H3P2O72−. b. It is Kb for the acid H3P2O72−. c. It is Ka for the acid H2P2O72−. d. It is Kb for the acid H2P2O7

Answers

The expression for the Ka for the given acid is:

Ka = [H2P2O7^2-] [H3O+] /[H3P2O7^2-]

Ka is the acid dissociation constant or the acidity constant. It is a measure of the acid strength when in solution. It is an equilibrium constant for the dissociation of the acid.

Answer:

It is Ka for the acid H3P2O72−.
