Answer:
30.0 L.
Explanation:
- To solve this problem; we must mention the rule states the no. of millimoles of a substance before and after dilution is the same.
<em>(MV)before dilution = (MV)after dilution</em>
M before dilution = 5.0 M, V before dilution = 3.0 L.
M after dilution = 0.5 M, V after dilution = ??? L.
∵ (MV)before dilution = (MV)after dilution
∴ (5.0 M)(3.0 L) = (0.5 M)(V after dilution)
<em>∴ V after dilution = (5.0 M)(3.0 L)/(0.5 M) = 30.0 L.</em>
The answer is c. 5.2 * 10^-5 Ms-1. The rate law for this reaction is given. So you only need to replace the letter with number given. And also calculate the unit. Then you can get answer.
Answer:
Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their ability to conduct heat and electricity. They are shiny like metals but brittle like nonmetals.
