Is N2 a compound or an element
katen-ka-za [31]

Answer:

Element.

General Formulas and Concepts:

<u>Chemistry</u>

  • Reading a Periodic Table
  • Diatomic Elements

Explanation:

Diatomic Elements are elements that are bonded to themselves. Naturally, these elements are not found alone in nature.

Diatomic Elements:

Hydrogen

Nitrogen

Oxygen

Fluorine

Chlorine

Bromine

Iodine

Since Nitrogen is a diatomic element, we would find Nitrogen in nature as N₂.

A ball with a density of 1100 kg/m3 is submerged in two liquids: water (ρ = 1000 kg/m3) and honey (ρ = 1400 kg/m3). What will th
Lapatulllka [165]

Hello!

So, we are given a ball with a density of 1100 kg/m³, and two liquids: water (1000 kg/m³) and honey (1400 kg/m³). Our goal is to determine if the ball will sink or float in the given liquids.

Let's take two common substances: water and ice. Water has a density of 1000 kg/m³ and ice has a density of about 917 kg/m³. You would notice that the ice is always floating when you put ice and water together. This would occur if you have other substances.

Here's what you should know:

  1. If the density of an object is greater than the liquid it is in, then that object will sink.
  2. If the density of an object is less than the liquid it is in, then that object will float.

Since the ball has a density of 1100 kg/m³, and water's density is 1000 kg/m³, then the ball will sink. If the ball is placed in honey, then it will float because the density of honey (1400 kg/m³) is greater than the ball's density.

Therefore, objects with a greater density than the surrounding liquid sink, while objects with a smaller density than the surrounding liquid float, which is the fourth choice.

How many grams of Fe are needed to create 32.5mol Fe3O4?
Mademuasel [1]

Answer:

5444.89 grams of Fe

Explanation:

1) We need the chemical equation for Fe3O4 to find the mole ratio for Fe to Fe3O4. Chemical equation:

3Fe+4H2O → Fe3O4+4H2

The mole ratio of Fe to Fe3O4 is 3:1

2) Now, we find how many grams of Fe are needed to produce 32.5 moles of Fe3O4.

32.5 moles Fe3O4x \frac{4 mole O}{1 mole Fe3O4} = 97.5 moles Fe needed to produce 32.5 moles of Fe3O4

3) Convert 97.5 moles of Fe into grams. The molar mass of Fe is 55.845g.

97.5 mole Fex\frac{55.845g Fe}{1 mole Fe} = 5444.8875g or 5444.89g.
