A student viewed the moon through binoculars one week after a new moon.Which image shows the phases of the moon that the students observed?

Answer:

The evidence of matter scattering light wave in many different directions is;

D. The colors on the water's surface match the colors in the sky

Explanation:

Light scattering is used to describe the sending of a given beam of light in many directions (by tiny particles) when the light passes through a medium, due to the disruption of the bath of the light ray as it bumps into the tiny particles

Water has the nature of absorbing the red light. The light that enters the water is scattered by the tiny particles in the water such that the blue light which is the spectrum of light water allows to pass through is reflected along with the reflection of the sky and the colors of the water surface match the colors of the sky.

Explanation:

The reaction can be said to be a single replacement reaction if one substance in a chemical reaction is replacing another one.

For example:

            A + BC →  AC + B

In such reactions there is a replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in solution.

The relative positions of the two elements in the activity series provides the driving force for a single replacement reaction. If one element that is to replace another in a compound is more active, the reaction will occur. If it is less reactive, there will be no reaction.

Answer: skeleton equation

Explanation:

Answer:

C

Explanation:

For every mol of Ca3N2 produced, you will need 3 mols of Ca

So the answer can be set up using a proportion.

3/1 = 6.3 / x               Cross multiply

3x = 6.3 *1                 Divide by 3

3x/3 = 6.3/3

x = 2.1

The answer is C

2.1 moles of Ca3N2 will be produced if you react 6.3 moles of Calcium with an excess nitrogen. Details about stoichiometry can he be found below.

The number of moles of a compound can be calculated as follows:

The chemical reaction between calcium and nitrogen is given as follows:

3Ca + N2→ Ca3N2

Based on the above reaction, 3 moles of calcium forms 1 mole of Ca3N2

Hence, 6.3 moles of calcium will produce 6.3/3

= 2.1 moles of Ca3N2

Therefore, 2.1 moles of Ca3N2 will be produced if you react 6.3 moles of calcium with an excess nitrogen.

Answer:

0.0045

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example 4.5×10⁻³

In standard notation

4.5 / 10³

0.0045

The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.

An earthworm has a closed circulatory system.

The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.

As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.

They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.

Answer:

30.11×10²³ molecules

Explanation:

Given data:

Mass of NaOH = 200.0 g

Number of molecules of water formed = ?

Solution:

Chemical equation:

2NaOH + H₂SO₄      →     2H₂O + Na₂SO₄

Number of moles of NaOH:

Number of moles = mass/molar mass

Number of moles = 200 g/ 40 g/mol

Number of moles = 5 mol

Now we will compare the moles of NaOH and H₂O.

                      NaOH         :        H₂O

                          2             :          2

                         5              :            5

Number of molecules of water:

1 mole contain 6.022×10²³ molecules

5 mol × 6.022×10²³ molecules / 1mol

Answer:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Explanation:

How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
