Which elements are likely to close electrons?

Answers

Answer 1

Answer:

Explanation:

In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. Hydrogen is an exception, as it will usually lose its electron. Metalloids and some metals can be can lose or gain electrons.

A student combines two clear liquid chemicals together in a beaker. When the two chemicals are combined, bubbles are formed, the solution turns blue, and you can see flakes of something forming on the bottom of the beaker. Is this a physical or chemical change? Why?

Answers

Answer:

chemical change

Explanation:

A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.

A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.

From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.

How did Thomson's experiment change Dalton's atomic model?

B. Thomson discovered that atoms did not rearrange when forming
compounds.
C. Thomson discovered that atoms of one kind of element could
have different masses.
D. Thomson discovered that the atom contained smaller particles
called electrons.

Answers

Answer:

D. thomson discovered that the atom contains smaller particles called electrons

Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.

What is Dalton's atomic model?

Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."

Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.

The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.

One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Thus, the correct option is D.

13) The scientist will have 6 grams of product as before but will have two grams of unreacted copper atoms because the mass ratio of copper to sulfur in this reaction is 2:1

Explanation:

12) Phosphorus trichloride has a trigonal pyramidal structure and is composed of three atoms of chlorine and one atom of phosphorus.

In the ball and stick model, an orange ball representing the phosphorus atom and three green balls representing chlorine atoms are connected by means of sticks that are coloured halfway green and orange respectively to represent the shared electrons between phosphorus and chlorine with the chlorine atoms forming the base of a triangular pyramid while the phosphorus atom forms the top of the pyramid.

13) The reaction between copper and sulfur to form copper sulfide is shown in the equation below:

Cu + S ---> CuS

1 mole of copper reacts with 1 mole of sulfur to produce 1 mole of copper sulfide

molar mass of copper = 64 g/mol; molar mass of sulfur = 32 g/mol, molar mass of copper sulfide = 96 g/mol

mass ratio of copper to sulfur = 63 g/ 34 g = 2

This means that 2 grams of copper will react with 1 g of sulfur to produce 3 grams of product. similarly, 4 g of copper will react with 2 g of sulfur to produce 6 grams of product.

Therefore 6 g of of copper will react with 3 g of sulfur. However, since the amount of sulfur available for reaction is 2 g only, 2 g of copper will be left unreacted after 4 g has reacted completely with 2 g of sulfur to produce 6 g of copper sulfide.

Explanation:

The wavelength of a wave is the difference between successive crests on a wave line. Waves with a very high wavelength have low energy.

Frequency is the number of waves that pass a point per unit of time. The higher the frequency, the higher a wave's energy.

From the given spectrum, wavelength increases from left to right. This puts radio waves as the wave with the longest wavelength. It is also right to say, it has the least energy. Also, frequency decrease from left to right. Gamma rays have the highest frequency in the spectrum. This is followed by x-rays.
