What is the density of an object with a mass of 130 g and a volume of 5 cm^3? please explain or im gonna fail 7th grade science

26 g/cm³

Explanation:

Given data:

Mass of object = 130 g

Volume of object = 5 cm³

Density of object = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

d = 130 g/ 5cm³

d =  26 g/cm³

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.
