How many moles are in 2.22 g of NaF

Why are tides important

how would use a similar chemical shorthand to write a representation of the molecules of iodine and fluorine

A 155.0 g piece of copper at 179 oC is dropped into 250.0 g of water at 28.1 oC. (The specific heat of copper is 0.385 J/goC.) Calculate the final temperature of the mixture. (Assume no heat loss to the surroundings.)

Sometimes the goals of different social institutions conflict, making it difficult to meet people's needs.

Variable that stays the same

The maximum amount of n2h4 (hydrazine) that can be prepared from 14 grams of nitrogen and 28 grams of hydrogen by the reaction n2 + 2 h2 = n2h4 is?

The molecules of a substance are moving rapidly in a container. The molecules do not interact with each other. If the container is opened, the molecules will escape from the container.

Why is fluorine a gas?

What is the empirical formula for a compound if a sample contains 3.72g of p and 21.28g of cl?-pcl5-pcl3-p2cl10-p2cl5

Use the equation 2HgO--> 2Hg+O2 to find how many moles of mercury are produced if 27 g of oxygen are produced. 2.1 1.3 2.6 2.4
