Answer:
~.1058 Moles
Explanation:
The formula for this question is the following.
1 mole of a compound/molar mass of the compound.
First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.
1 mole of H2O/ 17.01 g/mol H2O
We now know that in 1 mole of H20 there is 17.01 g.
Take 1.8g and divide it by 17.01, you get your answer.
Answer:
E
Explanation:
A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap
Answer:
All of the above.
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
This process is not reversible and a change of energy that is sometimes heat is given off.

Answer:
Moles of zinc chloride produced are 0.09942 moles.
Explanation:

Mass of zinc used = 6.5 g
Moles of zinc =
According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :
of zinc chloride
Moles of zinc chloride produced are 0.09942 moles.
