The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). ... Brush up on the periodic table of elements.
Answer:
D. extrusion ; granite.
Explanation:
The magma is extruded and cools to form granite.
Answer:
The final temperature of water is <u>20.5061 °C.</u>
Explanation:
Let the final temperature of water be 'x'.
Given:
Heat added to water is, 
Initial temperature of water is, 
Mass of water is, 
Now, heat is added to water and its temperature is increased. The temperature is increased because water absorbs all the heat.
Heat absorbed by water is given as:
where 'c' is specific heat capacity of water and its value is equal to 4.186 J/g °C.
Now, plug in the given values and simplify.
Now, from law of conservation of energy, we know that:
Heat absorbed by water = Heat added to water
So, the final temperature of water is 20.5061 °C.
The chemical formulas for their respective substances are the following:
Cadmium Sulfide: CdS
Sulfuric Acid: H₂SO₄
Hydrogen Sulfide: H₂S
This is a double replacement reaction where the substances of the reactants interchange to yield two products. The complete balance reaction would be:
<span>CdS (s) + H</span>₂<span>SO</span>₄<span> (aq) ----> CdSO</span>₄<span> (aq) + H</span>₂<span>S (g)
</span>
The other product is Cadmium Sulfate.
ANDESITE is a fine grained rock that formed when magma irrupt it onto the surface and crystallized quickly ANDESITE & DIORITE have a composition that is intermediate between basalt.This is because their parent magmas formed from the PARTIAL melting of a BASALTIC oceanic plate.
