Please Help! Find The Distance To Each Destination In AU. Use The Correct Conversion Factor.

Answers

Answer 1

Explanation:

The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)

The relationship between both units is given as;

1 Km = 6.68459e-9 Au

Kulper belt

6.5 billion km = 6.5e9 Km

1 Km = 6.68459e-9 Au

6.5e9 Km = x

Solving for x;

x = 43.45 Au

Alpha Centauri

44 trillion km = 4.4e13

1 Km = 6.68459e-9 Au

4.4e13 km = x

Solving for x;

x = 294121.83 Au

help !!! pretty please ❤️

Answers

Answer:

See below!

Explanation:

To find the symbol of the element, you have to use the periodic table.  

The mass number is the number of protons and neutrons in the atom.  

The atomic number is the number of protons in the atom.

You can find the number of protons from the periodic table.

You can find the neutrons by subtracting the mass number by the number of protons in the atom.

Unless you have an ion, you will have the same amount of electrons as you do protons.

To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment.  It is preferable to have the mass number and atomic number directly above each other.

If a metal that had reacted very
slowly with dilute acid was
tested with a concentrated
one, what would you predict
would happen?​

Answers

Answer:

It would react better than what with dilute and will furnish more hydrogen gas.

It would react faster due to the substances concentration percentage. The higher the concentration, the stronger it is, making it a quicker reaction with the metal.

Balance this equation. C(s)+H2(g) -> CH4(g)

Answers

C (s) + 2 H2 (g) = CH4 (g)

Answer:

shift to restore equilibrium

Explanation:

Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.

Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.

Equilibrium is the state of a reversible reaction when:

• two opposing reactions occur at the same rate;

• the concentrations of reactants and products are constant

What kind of mixture is frozen
yogurt with sprinkles, fudge, and
gummy bears? How can you tell

Answers

Answer:

a heterogeneous mixture

Explanation:

I can see all of the different parts of the frozen yogurt, and if I were to pick up a gummy bear, it would come out. Thus, it is not fully/completely mixed with the other components.

It is a heterogenous mixture.

What is the difference between Homogeneous  and Heterogeneous Mixtures ?

A type of mixtures where all the components are mixed uniformly called as homogeneous mixture.

Here the Particles are distributed in an uniform way, called as solution. Example rainwater, vinegar.

It consist of one phase, It can’t be separated out physically  

In heterogenous mixture, all the components are completely and equally mixed, particles can be seen under a microscope.

Here the Particles are distributed non-uniform way, Example: seawater, pizza, etc.

It can be in two or more phases and separated out physically
