Answers

Equation of motion:

$y_(f)=y_(o)+v_(o)t+ (1)/(2) at^(2)$

Since initial velocity is zero, the second term goes away:

$y_(f)=y_(o)+0+ (1)/(2) at^(2)$

$y_(f)=y_(o)+(1)/(2) at^(2)$

$y_(f)-y_(o)= (1)/(2) at^(2)$

$y_(f)-y_(o)=5.4m$

$5.4m= (1)/(2) at^(2)$

$(2(5.4m) )/(a) = t^(2)$

$a = g = 9.81 (m)/( s^(2))$

$(2(5.4m) )/(9.81 (m)/( s^(2) ) ) = t^(2)$

$1.1 s^(2) = t^(2)$ $\sqrt{1.1 s^(2)} = \sqrt{t^(2)}$

$t = 1.05s$

Answer:

1.05 s

Explanation:

The gas-phase reaction between nitrogen and oxygen was carried out in a device designed to maintain constant pressure. There are two cylinders of equal volume with a reaction arrow between them. The cylinder on the left has two molecules of O 2 and two molecules of N 2. The cylinder on the right has four molecules of N O. A constant pressure is applied to both cylinders Write the balanced chemical equation for the reaction between nitrogen oxygen. Include physical states.

Answers

The balanced chemicalequation for the reaction between nitrogen and oxygen is:

2N₂(g) + 2O₂(g) —> 4NO(g)

The equation between nitrogen and oxygen can be written as follow:

N₂(g) + O₂(g) —> NO(g)

The above equation can be balance as illustrated below:

There are 2 atoms of O on the left side and 1atom on the right side. It can be balance by writing 2 before NO as shown below:

N₂(g) + O₂(g) —> 2NO(g)

Multiply the equation by 2, we have:

2N₂(g) + 2O₂(g) —> 4NO(g)

The equation is balanced!

Answer:

2N₂(g) + 2O₂(g) ----> 2NO(g)

Explanation:

Gaseous nitrogen and gaseous oxygen reacts in a molar volume ratio of 1 : 1 to produce nitrogen (ii) oxide.

In the reaction, two molecules of nitrogen gas combines with two molecules of oxygen gas in the cylinder to form two molecules of nitrogen (ii) oxide. The equation of the reaction is given below:

2N₂(g) + 2O₂(g) ----> 2NO(g)

Nitrogen (ii) oxide is formed naturally during lightning bolts. The heat released the lightning flashes causes the nitrogen and oxygen in air to combine to form nitrogen (ii) oxide. The nitrogen (ii) oxide formed however, quickly reacts with more oxygen to form nitrogen(ii) oxide.

Nitrogen (ii) oxide is a colorless, poisonous gas. It is slightly denser than air and almost insoluble in water. it is also neutral to litmus.

True or False.. Although the Kinetic Theory of Matter states that the particles that make up all matter are in perpetual motion, we know that this isn’t really correct because solids don’t move.

The answer is false because kinetic energy contains motion!

The answer is false because the Kinetic Theory of Matter does not involve particles that make up all matter

The horizontal surface on which the block of mass 2.2 kg slides is frictionless. The force of 27 N acts on the block in a horizontal direction and the force of 81 N acts on the block at an angle as shown below is the magnitude of the resulting ac celeration of the block? The acceleration of gravity is 9.8 m/s ^ 2

Answers

To determine the magnitude of the resulting acceleration of the block, we need to resolve the forces acting on the block into their horizontal and vertical components.

The force of 27 N acts horizontally, so its horizontal component is 27 N.

The force of 81 N acting at an angle needs to be resolved into its horizontal and vertical components. The horizontal component is given by 81 N * cosθ, where θ is the angle between the force and the horizontal direction. Since the angle is not specified in the question, we cannot determine the exact value of the horizontal component without that information.

Once we have the horizontal components of the forces, we can calculate the net horizontal force acting on the block by summing up all the horizontal components. In this case, the only horizontal force is the force of 27 N, so the net horizontal force is 27 N.

Using Newton's second law, F = ma, where F is the net force and m is the mass of the block, we can solve for the acceleration.

a = F / m
a = 27 N / 2.2 kg
a ≈ 12.27 m/s^2

Therefore, the magnitude of the resulting acceleration of the block is approximately 12.27 m/s^2.
