What type of reaction is shown below? Ba(OH)2 + 8H20 + 2NH4NO3 + heat ?10H2O + 2NH3 + Ba(NO3)2

Answers

Answer 1

Answer: Double Displacement Reaction

An element from each of two compounds switch places.
Example: compound + compound ⇒ compound + compound

Chemical reactions are processes in which substances change into other substances. A chemical reaction takes place if one or more of these occur:
Color changes - Different combinations of molecules reflect light differently. A color change indicates a change in molecules.
Heat content changes- In all chemical reactions, the heat content of the reactants and the heat content of the products is never the same. Sometimes the difference is great and can be easily detected. At other times, the difference is slight and more difficult to detect.
Gas produced - Whenever a gaseous product forms in a liquid solution, bubbles can be seen. A colorless gas produced in a reaction of solids is much harder to detect.
Precipitate forms- Precipitates are insoluble products formed by a reaction taking place in a liquid solution. This insoluble product will eventually settle to the bottom, but might immediately appear by turning the clear solution cloudy.

The ____ states that between 15 and 20 billion years ago, the universe began expanding out of an enormous explosion. A. H-R diagram
B. binary star theory
C. Big Bang theory
D. "big crunch" theory

Answers

In my opinion, the correct answer among the choices listed above is option C. The Big Bang Theory states that between 15 and 20 billion years ago, the universe began expanding out of an enormous explosion. However, the exact number is approximately 13.8 billion years ago.

Answer:

Big Bang theory

Explanation:

The big bang theory describes the beginning of the universe. According this theory, all the matter of the universe was confined at a point and about 15-20 billion years ago, it started expanding out of a huge explosion -the big bang. The universe has been expanding since then. The discovery of cosmic microwave background radiation provides the evidence to this theory.

Thus, the correct option is C.

Who was Albert Einstein?

A force of 450 N accelerates a box across a frictionless surface at a rate of 15 m/s2. Find the mass of the box?A) 30 N

B) 30 kg

C) 6,750 N

D) 6,750 kg

Answers

Second Law of Newton: Net force equals mass times acceleration

F = m*a => m = F/a

m = 450N / 15 m/s^2 = 30 kg

Answer: option B) 30 kg

It would be: m= F/a = 450 N / 15 m/s^2 = 30 Kg

A 0.40-kg cart with charge 4.0 x 10-5 C starts at rest on a horizontal frictionless surface 0.50 m from a fixed object with charge 2.0 x 10-4 C. When the cart is released, it moves away from the fixed object. (a) How fast is the cart moving when very far (infinity) from the fixed charge

Answers

Answer:

26.82m/s

Explanation:

Given

Mass = m= 0.4kg

Initial Velocity = u = 0

Charge = 4.0E-5C

Distance= d = 0.5m

Object Charge = 2E-4C

First, we'll calculate the initial energy (E)

E = Potential Energy

PE = kQq / d

Where k = coulomb constant = 8.99E9Nm²/C²

Energy is then calculated by;

PE = 8.99E9 * 4E-5 * 2E-4 / 0.5

PE = 143.84J

Energy = Potential Energy = Kinetic Energy

K.E = ½mv² = 143.84J

½mv² = ½ * 0.40 * v² = 143.85

0.2v² = 143.85

v² = 143.85/0.2

v² = 719.25

v = √719.25

v = 26.81883666380777

v = 26.82m/s

Hence, the object is 26.82m/s fast when the cart moving is very far (infinity) from the fixed charge

Why don't satellites in orbit fall to the ground? Why they don't fly off into space?

Answers

-- The satellite IS falling, but it never reaches the ground because
it's also moving "sideways" ... in the direction of the orbit ... and
because the Earth is shaped like a sphere.

The satellite is moving sideways fast enough so that by the time
it falls 1 foot, the Earth's surface has curved down away from it
1 foot, so it's still the same distance from the Earth's surface.

-- A satellite doesn't fly off into space for the same reason that
a yo-yo doing "around the world" on the end of a string doesn't
fly off ... It's being held onto the circle by the tension in the string,
a force that keeps pulling it toward the center of the circle.

There's a force on the satellite too, that keeps pulling it toward
the center of the Earth. It's the gravitational force between the
Earth and the satellite.

The satellite doesn't fly off into space for the same reason that
YOU don't do that either.

The complex balancing act between a satellite's forward speed and the gravitational force pressing upon it prevents satellites in orbit from falling to the ground or shooting off into space.

When a satellite is put into orbit, it reaches a fast enough speed to escape the Earth's gravitational attraction.

By continuously falling towards the Earth and moving forward at the same time, the satellite may maintain a stableorbit.

This motion results in a curved course, which causes the Earth to be in a constant state of freefall.

Although the satellite is constantly being drawn towards the Earth by gravity, its forward velocity prevents it from dropping.

Thus, satellites don't fall or break free into space and are kept in a stable orbit.
