Answer:

Ba(ClO3)2 → BaCl2 + 3O2

Explanation:

According to this question, Barium chlorate (Ba(ClO3)2) breaks down to form barium chloride (BaCl2) and oxygen (O2). The equation is as follows:

Ba(ClO3)2 → BaCl2 + O2

One would notice that this equation is not BALANCED because the number of atoms of each elements are not the same on each side of the equation.

- There is one atom of Barium (Ba) on both reactants and product side

- There are two atoms of chlorine (Cl) on both reactants and product side

- There is an unven number of atoms of oxygen on both sides. That is, 6 atoms of oxygen on reactant side but 2 atoms on product side.

To balance the number of oxygen atom, we add coefficient 3 to the oxygen atom on the product side to have 6-6 for both sides. That is;

Ba(ClO3)2 → BaCl2 + 3O2

A liquid-fueled rocket engine has two liquids, usually called the fuel and the oxidizer. Which two liquids are most commonly use
hammer [34]

Answer:

A liquid-fueled rocket has two liquids (liquids are good because of the density, they need less space than a gas to be stored), such that these liquids are called the fuel and the oxidizer.

These liquids are injected into a system that leads to a combustion chamber, where the liquids are mixed (we need to mix the fuel with the oxidizer to enable the combustion of the fuel) and burned to produce thrust.

Some common examples of oxidizers are liquid oxygen, which may be combined with fuels like liquid hydrogen, liquid methane, kerosene and hydrazine.

Other oxidizers are liquid fluorine (which also can be combined with the fuels liquid hydrogen and hydrazine), nitrogen tetroxide (which can be combined whit kerosene, hydrazine and other fuels) and FLOX-70, which can only be combined with kerosene.

The "most commonly used" may depend on the country and the type of liquid propellant ( petroleum, cryogens, and hypergols)

Such that the most common oxidizer may be liquid oxygen, and the most common fuel the kerosene.

Bubba falls out of a plane flying over his peanut field. What will bubba speed be after falling for 8 seconds?
chubhunter [2.5K]

Variables we know:

t = 8 seconds

Vi = 0 m/s

g = -9.81

Δy = ?

Vf = ?

Equation we will be using to solve for Vf: Vf = Vi + gt

Steps to solve:

Vf = (0) + (-9.81)(8)

Vf = -78.48 m/s

Hope this helps!! :)
