Explanation / Answer

Question 1

the equivalent of 10cm^3 is

10 cm^3 = 0.01 litre---------answer

=====================================

Question 2

The number of grams equivalent to 1.5 moles of lead (II) oxide

Answer d) 335 grams-------------answer

1.5 moles of lead (II) oxide =334.7991 grams

molecular weight of Lead(II) Oxide or grams
The molecular formula for Lead(II) Oxide is PbO.
The SI base unit for amount of substance is the mole.
1 mole is equal to 1 moles Lead(II) Oxide, or 223.1994 grams.

=====================================================================================

Question 3

The number of grams in 4.55 x10^16 molecules of carbon dioxide is

mass of 1 mole carbon dioxide =44.01 g/mol ----- -= 6.023 x10^23 molecules

-----------------------------------------------------------x grams-------------------4.55 x10^16 molecules

= (4.55 x10^16 molecules /6.023 x10^23 molecules) 44.01 g/mol

= (4.55 / 6.023) 44.01 = 3.33 x10^-6-----------------answer

=========================================================

Question 4

4) Nano means

b)10^-9-answer

====================================================

Question 5

In the balanced reaction between barium oxide and aluminium to form aluminium oxide and barium

3 BaO + 2 Al = 3 Ba + Al2O3

answer c) 3 ---------------answer

===============================================================

Question 6

The equivalent of 2.51 pounds is

c) 1.14 x10^3

=======================================================

Question 7

SO is an example of

e) covalent compound

====================================

Question 8

The equivalent of 22c

22+273=295 k------answer

=============================

Question 9

A density of 1.2 g/ml is equivalent

a) 0.00264555 =2. X10^-3 lb/cm^3 -----------answer
