1. A 24.50 g piece of metal displaces 2.6 ml of water. Calculate the density of the

metal?

9.42g/cm3

Explanation:

Data obtained from the question include the following:

Mass of the metal = 24.50g

Volume of metal = 2.6 ml = 2.6cm3

Density =..?

The density of a substance is defined by the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density = Mass /volume

With the above formula, we can obtain the density of the metal as follow:

Density = Mass/volume

Density = 24.50g/2.6cm3

Density = 9.42g/cm3

kuchisake-onna (口裂け女, "slit mouth woman ") is a malevolent figure appearing in japanese ghost stories, possibly dating back to the edo period. she takes the form of a masked woman who approaches people and asks them if they believe she is pretty.

explanation:

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
