Sodium reacts with water to produce sodium hydroxide and hydrogen gas:
2Na + 2H2O → 2NaOH + H2.

a. How many moles of water are required to react with 14 moles of sodium?

b. How many moles of NaOH will result if 15 moles of sodium are used?

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
