Answer : The formula unit of Sr & Cl is and the formula unit of Al & S is
Explanation :
Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.
For the formula unit of Sr & Cl, two chloride ions are needed to neutralize the one strontium ion.
For the formula unit of Al & S, three sulfide ions are needed to neutralize the two aluminium ion.
The formula unit of and are shown below.
The semifluid or hot fluid substance within or below the crust of the Earth from which lava and other igneous rock are produced by cooling is known as magma.
The temperature and pressure elevate with depth, finally reaching to a level wherein the strongest rock is melted, transforming into magma. When the magma comes into contact with water, it instantly gets transformed into a rock, that is, the outside solidifies briskly, and the inside of it gets cold.
