A length of wood has a labeled length value of 2.50 meters. You measure its length three times. Each time you get the same value: 2.35 meters. What is the percent error of your measurements? *

Answers

Answer:

6%

Explanation:

Actual length of the wood is 2.5 m

Observed length of the wood is 2.35 m

We need to find the percent error of your measurements. The formula of the percentage error is given by :

[tex]\%=\dfrac{|\text{observed-actual}|}{\text{actual}}\times 100\\\\\%=\dfrac{2.5-2.35}{2.5}\times 100\\\\\%=6\%[/tex]

Hence, the percentage error is 6%.


Which statement accurately describes the chemical symbol of an element?

O The chemical symbol is always a single letter.
O The chemical symbol always starts with the same letter as the name of the element.
O The chemical symbol always begins with a capital letter.
OThe chemical symbol can be shared by more than one element.

Answers

Answer:

The chemical symbol always begins with a capital letter.

Explanation:

Answer:

c

Explanation:

The chemical symbol of an element always starts with an chemical letter so here the answer is that the chemical symbol always begins with a capital letter.

It can be seen in the different elements chemical symbol .

For example, Tin is having chemical symbol as Sn while lead is having chemical symbol as Pb.

In both these elements, the chemical symbol starts with a capital letter but none of these have their symbol starts with same letter as their name.

The table shows four samples of carbon dioxide and the temperature of the water that they were dissolved in. Which of the samples most likely had the lowest solubility? I know the answer is sample one (78) but i can't find the right words to explain my answer.

Answers

Answer:

Sample 1 = 78°

Explanation:

As per the question, while testing the solubility of a solution comprising of water and carbon dioxide, sample 1 is likely to have the lowest solubility with the temperature of the water being 78°, the maximum. The reason for this result is that the 'solubility of carbon dioxide in the water' falls with an increase in the temperature due to the increase in kinetic energy which will enhance the motion between the molecules and allow them to escape.' Thus, the water with maximum temperature will have the lowest solubility. Hence, sample 1 is the correct answer.

If one end of an iron bar is heated, what causes thermal energy to transfer to the other end? a radiation b conduction c heat of fusion d convection

Answers

Answer:

Option B:

Conduction

Explanation:

Conduction is the transfer of heat from one molecule to another between two solids that are in direct contact with each other. For the conduction of heat to occur, the medium involved must be solid. This is because the molecules of solids are closely packed together and they cannot freely move about. The heat flowing through them can easily be passed on from one molecule to the other until it reaches all the parts of the object. This is exactly what will happen to the iron bar. Thermal energy from one end of the bar will get transferred between the molecules of the iron bar until it reaches the other end.

Convection on the other hand involves the transfer of heat through a liquid medium.

Radiation involves teh transfer of heat in a vacuum.

b) conduction

How many moles ar Li are in 9.53x^24 atoms of Li?

Answers

Answer: 15.83 mol

Explanation:

To convert from atoms to moles, we will need to use Avogadro's number.

Avogardo's number: 6.022×10²³ atoms/mol

[tex]9.53*10^{24} atoms*\frac{1mol}{6.022*10^2^3 atoms} =15.83 mol[/tex]

The head of a pin is 1.5 × 10-3 m in diameter. If 1.136 × 107 atoms of oxygen can fit across the head of a pin, what is the atomic radius of oxygen?

Answers

About five million million hydrogen atoms could fit. Some factors would affect that number like the area of the head and the size of atoms (as well as attractions between atoms). Some atoms are larger than others.

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

The head of a pin is 1.5 × 10⁻³ m in diameter. If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin, the diameter of each oxygen atom would be:

[tex]\frac{1.5 \times 10^{-3}m }{1.136 \times 10^{7}atom} = 1.32 \times 10^{-10}m/atom[/tex]

The atomic radius of oxygen would be half of its diameter.

[tex]\frac{1.32 \times 10^{-10} m}{2} = 6.60 \times 10^{-11} m[/tex]

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

My region does not have drastic changes and temperature and the climate is hot most of the year. For this reason, it is necessary to use materials that are thermal insulators, on the contrary we need to use materials that are not good thermal insulators such as concrete blocks, bricks, cement and ceramics, we will also need common tiles and rafters to support them.

Is this statement true or false? Why?
Chemical reactions are nothing more than rearrangements of protons.

Answers

Answer:

False. Answer in pic above

In fact protons have no role in chemical reactions. The regrouping of atoms itself forms the new products in chemical reactions. The reactions involves the loss/gain or sharing of electrons.

What is a chemical reaction ?

A chemical reaction is a chemical change in which two or more atoms combine together to form a new product or a compound decomposes to form its constituent compounds. This  involves breaking or making of bonds.

In a chemical reaction, no change occurs in the nuclear composition but the valence electrons are involved in the reaction. Atoms loss or gain electrons or share valence electrons with other atoms to form ne compounds.

The electrostatic force of attraction or the overlapping of atomic orbitals make the new products in a chemical reaction. Hence, the statement is false.
