When making a solution by diluting a stock solution. Suppose when a solid is stirred into a liquid and dissolves,
a homogenous mixture is formed. When the mixture does not dissolve, the mixture
is heterogeneous.
Answer:
A. Steel
Explanation:
Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula.
Answer:
Explanation:
Hola,
Dado que la molaridad de una solución es definida en términos de las moles de soluto y el volumen de la solución en litros:
Primero debemos calcular las moles de hidróxido de sodio, teniendo en cuenta que su masa molar es de 40 g/mol:
Luego, el volumen el litros:
Así, calculamos la concentración molar de la solución:
Saludos!
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.
Answer:
The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
