Answer:

Explanation:

Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring, and flagging because of its durability and attractive appearance.

Answer:

Deep within the Earth's crust rocks can be put under huge pressures and temperatures are very high. These conditions can cause the minerals in the rock to change. This process is called metamorphism. Limestone can change into marble, shale and mudstones into slate, and igneous rocks like granite can turn into gneiss.

How many grams of tin would occupy 5.5 L if it had a density of 7.265

lisabon 2012 [21]

In order to find the mass of tin with the given volume of 5.5 L and density of 7.265, we will use the formula
Density = Mass / Volume

We will just multiply both sides of the equation by the volume and we will get:
Mass = Volume x Density

We can now solve the problem by substituting the given.

Mass = 5.5 L x 7.265 g/L
Mass = 39.96 g

Answer: there are 39.96 grams of tin

When potassium metal is placed in water a large amount of energy is released as potassium hydroxide and hydrogen gas are produce

Ann [662]

Explanation:

$2K(s)+2H_2O\rightarrow 2KOH(aq)+H_2(g)$

The given reaction is redox reaction but not combustion reaction.

Redox reaction : It is a chemical reaction in which oxidation and reduction occurs simultaneously.Oxidation is gaining of electrons and reduction is loosing of electrons.

$K\rightarrow K^++e^-$ oxidation

$2H^++2e^-\rightarrow H_2$ reduction

Potassium when reacts with water ,gives potassium ion in aqueous medium and combines with hydroxide ion present in water to form potassium hydroxide where as $H^+$ ions of water by gaining electrons (from potassium in water) gives hydrogen gas.
