Answer:
osmosis is the answer
Explanation:
cause air rises from lower concentration to lower concentration
Explanation:
Below are attachments containing the solution
Answer:
the diaphragm and rib muscles contract
Explanation:
Inhalation is the set of movements that allows air to enter the lungs. In this process occurs the contraction of the diaphragm, causing its lowering. The intercostal muscles also contract causing the ribs to lift. This causes the chest to grow larger and the internal pressure of the lungs to become smaller than the external. With the reduction of intrapulmonary pressure, air ends up entering the airways and reaching the alveoli for gas exchange to occur.
First, you have to know what reacts with Aluminum Nitrate so that you can balance the equation and find out the stoichiometric coefficient. I found a similar question from another website as shown in the picture attached. Balancing the reaction would result to:
2Al(NO₃)₃ + 3FeCl₂ --> 3Fe(NO₃)₂ + 2AlCl₃
<em>The coefficient is 2.</em>
