KiRa [710]3 years ago
7 0

Answer:

  • Bases are ionic compounds that produce negative hydrogen ions (OH⁻) when dissolved in water.
  • An example of a base is Sodium Hydroxide (NaOH).
  • Bases have a bitter taste.
  • Bases feel slippery.
  • Bases conduct electricity when dissolved in water.
  • Bases change litmus paper from red to blue in colour.
  • They react with acids to form a salt and water, this process is called neutralisation.
  • The pH of bases ranges from 8-14.
  • Turns phenolphthalein pink.

Hope this helps!

Why are elements and compounds classified as pure substances?
IgorC [24]

Pure substances contain a single type of chemical species, either element or compound. Elements cannot be further broken into simpler units by chemical methods. If we consider a sample of elements, it has a single type of atoms present in it. A compound has one or more atoms bound together chemically. Compounds can be broken down into simpler units by chemical means. When we consider a sample of a single compound say water, it has all the pure water molecules. Hence, elements and compounds are pure substances.

What volume of 0.140 HCl is needed to neutralize 2.58 of Mg(OH)2<br> ? ...?
elena-s [515]
To make a first step you have to know the balanced form for neutralization formula: Mg(OH)2(aq)+2HCl(aq)--\ \textgreater \ 2H2O+Mg(aq)+Cl(aq)&#10;
According to this, you can <span>calculate what you are being asked :</span>0.0442molMg(OH)2(x)(2molHCl)/(1molMg(OH)2)=0.0885molHCl
Then we have : 0.140MHCl=0.140(mol/L)HCl
Hope everything is clear, here is the exact answer you need : V=(0.0885molHCl)/(0.140(mol/L)HCl)=0.632LHCl&#10;

Propane (C3H8) is widely used in liquid form as a fuel for barbecue grills and camp stoves. For 67.7 g of propane, determine the
viva [34]

Answer:

A. 1.54 mole.

B. 55.39g of carbon

Explanation:

A. Determination of the number of mole in 67.7g of C3H8.

Mass of C3H8 = 67.7g

Molar mass of C3H8 = (3x12) + (8x1) = 44g/mol

Number of mole of C3H8 =..?

Number of mole = Mass/Molar Mass

Number of mole of C3H8 = 67.7/44

Number of mole of C3H8 = 1.54 mole

B. Determination of the mass of carbon in the compound.

This is illustrated below:

The mass of C in compound can be obtained as follow:

=> 3C/C3H8 x 67. 7

=> 3x12 / 44 x 67.7

=> 36/44 x 67.7

=> 55.39g

Therefore, 55.39g of carbon is present in the compound.
