What are the parts of this water wheel system?Label the water wheel to show the matter and forms of energy that flow through the system?

Answers

Answer 1

Answer:

Water, wheel and paddles or bucket are the parts and mechanical energy is produced.

Explanation:

The parts of water wheel system are water, wheel and paddles or bucket. The main purpose of water wheel system is to generate useful energy by using the flowing or falling of water on the wheel. We use this water wheel system for the conversion of kinetic energy into mechanical energy such as water mill or hydroelectric plant in which the blades movement is responsible for the generation of electricity.

Answers

Answer:

See explanation

Explanation:

A salt is made up of homogeneous particles while sand is made up of heterogeneous particles. Salt is a crystalline substance while sand is a coarse substance.

If salt and sand are mixed with water, salt forms a solution with water, hence, salt cannot be caught on filter paper. However, sand does not form any chemical specie with water hence it is caught on the filter paper as a solid.

significant figure of 87 000 ms​

Answers

Answer:

2 significant figures.

Explanation:

Significant Figures Rules:

1. Anything that isn't a zero is a sig fig

2. If a decimal point comes after the ones digit, everything before the decimal is counted as sig fig (i.e 2000. would be 4 sig figs).

3. If we are dealing with small decimals, the zero before and after the decimal (i.e 0.002) is a placeholder and is not counted as sig figs.

4. Any zeros between 2 significant digits is considered in sig figs (i.e 2002 would be 4 sig figs)

Since we are dealing with 87000, we see that we have no decimal point. That means our only sig figs are 8 and 7, which equals 2 sig figs.

Isotopes of the same element have the same atomic number and different mass numbers. Hence, option C is correct.

What are Isotopes?

Isotopes are defined as chemical species which have the same number of protons but differ in the number of neutrons.

It can also be said that they are the chemical species of the same element which have the same atomic number but have different mass numbers.

For Example, C12 and C14 are the isotopes of carbon elements, which have the same atomic number but a different mass numbers.

Hence, option C is correct.

What is the maximum number of covalent bonds that an oxygen atom with atomic number 8 can make with hydrogen?

Answers

Answer:

2

Explanation:

Oxygen has 6 electrons in its valence shell.  Since an atom can have a maximum of 8 electrons in the valence shell, oxygen has 2 empty spots in its valence.  This means that oxygen can make 2 single covalent bonds.

The maximum number of covalent bonds that an oxygen atom with atomic number 8 can make with hydrogen is: 2.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.  Typically, valency is measured by the amount of hydrogen atoms that a chemical element can combine with or displace to form a molecule or chemical compound.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

From the periodic table, we know that an oxygen atom has an atomic number of eight (8). Thus, oxygen has six (6) electrons in its valence shell and two (2) empty shells to form a covalent bond with hydrogen.  

Generally, the maximum number of electrons an atom can hold in its valence shell is eight (8) and since oxygen has has six (6) electrons in its valence shell; it ultimately implies that the maximum number of covalent bonds that an oxygen atom with atomic number of eight (8) can make with hydrogen is two (2) covalent bonds.

If you find the mass of a sample to be 42.1 g and the actual mass is 42.0 g. What wold be the percent error

Answers

Answer:

0.24%

Explanation:

The following data were obtained from the question:

Measured value = 42.1 g

Actual value = 42 g

Percentage error =?

Percentage error can be obtained by using the following formula:

Percentage error = |Measured value – Actual value | / Actual value × 100

With the above formula, we can obtain the percentage error as follow:

Measured value = 42.1 g

Actual value = 42 g

Percentage error =?

Percentage error = |42.1 – 42| / 42 × 100

Percentage error = 0.1/42 × 100

Percentage error = 10/42

Percentage error = 0.24%

Therefore, the percentage error is 0.24%

In recent research, strontium ions have been used for bone regeneration within humans as a calcium replacement. Based on your knowledge of periodic information, explain why is strontium a good substitute for calcium instead of other elements on the periodic table. [Hint: think about the way elements are organized based on their common characteristics] *

Answers

Answer:

Strontium, as opposed to other elements on the periodic table (with the exception of others in the same group/column i.e., the vertical direction), is a good substitute for Calcium because they are in the same group.

Explanation:

This is because elements of the same group behave similarly and have similar properties. This is due to the fact that elements of the same group (in the vertical direction) have the same number of valence electrons.

The atoms that make solids do not move at all which is why they keep their shape. Atoms making gases have the least amount of kinetic energy while solids have the most.

Answers

Answer:

Atoms making liquids have less attraction than solids, but more than gases

Explanation:

The attraction between atoms in different molecules in a solid is very strong due to strong intermolecular forces present in a solid. However, such intermolecular forces are weaker in liquids than in solids.

This implies that the solid has higher intermolecular forces of attraction compared to gases and liquids. Based on the negligible degree of intermolecular forces between them, a gas has the weakest intermolecular forces hence the atom has very minimal interaction between them.
