The lab procedure involves several factors, listed below. some were variable and some were constant. label each factor below v for variable or c for constant. __ mass of the water in the calorimeter __ mass of the metal __change in temperature of the water __change in temperature of the metal __volume of water in calorimeter __calorimeter pressure __specific heat of water

Answer :

V - mass of the water in the calorimeter

V - mass of the metal

V - change in temperature of the water

V - change in temperature of the metal

C - volume of water in calorimeter

C - calorimeter pressure

C - specific heat of water

Explanation :

Variables : It is a factor that changes during the experiment or calculation.

Constant : It is a factor that does not change during the experiment or calculation.

In a calorimeter, the heat absorbed is equal to the heat released.

As we know that,  

where,

= mass of water in calorimeter

= mass of metal

= change in temperature of the water

= change in temperature of the metal

= specific heat of water

= specific heat of metal

From this, we conclude that the value of specific heat of water is constant while the other are variables.

The volume of water in calorimeter, calorimeter pressure is also constant.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
