Hydrogen gas (H2) and oxygen gas (O2) react to form liquid hydrogen peroxide (H2O2). Which statement is true about the reaction?

1 answer:

4 0

HYDROGEN GAS + OXYGEN GAS= HYDROGEN PEROXIDE H2+O2=H2O2 HYDROGEN PEROXIDE IS A LIQUID BECAUSE HYDROGEN PEROXIDE CAN NEVER BE A SOLID BECAUSE TWO LIQUIDS CAN NEVER FORM A GAS IT IS IMPOSSIBLE NO MATTER THE CONDITION

Railroad car A rolls at a certain speed and makes a perfectly elastic collision with car B of the same mass. After the collision

lozanna [386]

Answer:

The speed of the car B after the collision is same as the speed of the car A before collision.

Explanation:

lets take the mass of the car A = m kg

Initial speed of the car A = u m/s

The mass of the car B = m kg

Initial speed of the car A = 0 m/s

The final speed of the car A = 0 m/s

The final speed of the car B = v

There is no any external force on the masses that is why the linear momentum will be conserve.

Initial linear momentum = Final linear momentum

P = mass x velocity

m u + m x 0 = m x 0 + m v

m u + 0 = 0 + m v

m u = m v

v= u

Therefore we can say that ,the speed of the car B after the collision is same as the speed of the car A before collision.

The amount of oxygen in the reactants is 4 atoms. In the products, the oxygen is distributed to water (H2O) and O2 gas. Which co

Reil [10]

Answer:

2 in front of water and 1 in front of oxygen

Explanation:

This question is describing balancing a chemical reaction. A balanced chemical reaction has the same number of atoms of each elements on both the reactant and product side. According to the question, the reactants contains 4 atoms of oxygen. The reactants give rise to water (H20) and O2 in the products side.

This reaction is most likely the decomposition of hydrogen peroxide (H2O2) as follows:

H2O2 (l) ----> H2O (l) + O2(g)

Based on the description, H2O2 will be 2H2O2 as it is said to contain four atoms of oxygen. This means that, in order to have a balanced equation, we must place coefficient 2 in front of water and coefficient 1 in front of oxygen. That is;

2H2O2 (l) ----> 2H2O (l) + O2(g)
