Brass is a homogeneous mixture.
In the liquid state, the copper and zinc formed a solution.
They did not separate from each other when the brass solidified.
Thus, brass is a solid solution.
The sample will lose half of its mass after 4 hours. The half life.
82=4
The sample will lose half of the remaining four after another half life.
42=2 Hope this helps! :)
Explanation:
Your chemical equation should look like this:
Li3PO4 + AlF3 --> 3LiF + AlPO4
This is the balanced equation for a double-displacement reaction
Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through. Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
