Selena is learning about how engineers choose metals for spacecraft. She discovers that spacecraft engineers often mix other metals with titanium. Titanium is a metal that is both lightweight and strong. It also resists corrosion. Selena wants to compare titanium with other metals. She looks at the cell from the periodic table that represents titanium.




Explain what each of the four items in the cell represents. Then, classify titanium as an alkali, alkali earth, or transition metal.

Answers

Ti is a transition metal.

Further explanation

Chemical symbol represent element or compound

The elements are arranged in the periodic system

1. 22

This is the atomic number of Titanium

The Atomic Number (Z) indicates the number of protons of an element

2. Ti

This is the symbol (chemical formula) of titanium

3. 47.90

This is the mass number of Titanium

Mass Number (A) = Number of protons + Number of Neutrons

Atomic Number (Z) = Mass Number (A) - Number of Neutrons

4. Titanium

This is the name of the element

To determine which group, alkaline, alkaline earth or transition it can be seen from the electron configuration

alkali and alkali earth : configuration from orbital 1s-7s

transition : configuration from orbital 3d-6d (Block d)

Electron configuration from Ti : [Ar] 3d²4s²

if we look at the configuration, then Ti is in the d block which is included in the transition metal

Answers

D. Hydrogen

an element is a pure substance that cannot be broken down

Answer:

[tex]\boxed {\tt D. \ Hydrogen}[/tex]

Explanation:

An element has a uniform composition, cannot be broken down by chemical change, every atom has the same atomic number, and can be found on the Periodic Table.

Water is made of hydrogen and oxygen atoms (H₂O) so it is not an element.

Table salt is made of sodium and chloride atoms (NaCl) so it is not an element.

Iron oxide is made up of iron and oxygen atoms, so it is not an element.

Hydrogen is an element. It can be found on the Periodic Table as element H.

The correct answer is D. Hydrogen

3.6 x 10-6 in standard notation.

Answers

Answer: 0.000036

Explanation:The standard form is just the normal method of depicting a number. To get from scientific notation to standard form, you would multiply the number from the scientific notation by the increasing / decreasing factor (10n). When the factor decreases, the 10 is raised to a negative power and the decimal moves to the left n amount of times (example the

10−5 moves your decimal in 3.6 over to the left 5 times leaving you with 0.000036). The opposite is true for increasing factors.

3.6 x 10⁻⁶ in standard notation is 0.0000036.

Standard notation refers to the conventional symbols, terms, and formats used to represent mathematical, musical, scientific, or other technical concepts.

Scientific notation is a way to express very large or very small numbers using powers of 10. It is commonly used in scientific and mathematical calculations to represent numbers that are too big or too small to be conveniently written in standard decimal notation.

To convert a number in scientific notation to standard notation, multiply the coefficient by the power of 10.

In 3.6 x 10⁻⁶, the coefficient is 3.6 and the exponent is -6.

To convert it to standard notation:

3.6 x 10⁻⁶  = 0.0000036

Match each description below with the name of the local wind system being described. warm, dry downslope wind affecting Southern California monsoon wind blowing from a valley up a mountain slope valley breeze a seasonally changing wind Santa Ana wind generated by cold thunderstorm downdrafts haboob

Answers

Answer:

warm, dry downslope wind affecting Southern California - Santa Ana wind

a seasonally changing wind- monsoon

wind blowing from a valley up a mountain slope - valley breeze

generated by cold thunderstorm downdrafts - haboob

Explanation:

The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.

Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.

Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.

Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.

What mass of benzene takes
up
325 mL if its density is
0.874 g/mL?

Answers

Answer:

The answer is 284.05 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 325 mL

density = 0.874 g/mL

We have

mass = 325 × 0.874

We have the final answer as

284.05 g

Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R

Answers

Answer:

Unit of resistance is Ω (Omega).

Explanation:

The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :

V = IR

R is resistance

Its unit is Omega and it is represented by Ω.

The unit of the electrical resistance is ohm Ω

The symbol of resistance is R.

Hence Option A) Symbol: R, Unit : Ω is the correct answer

What is resistance?

Resistance is simply the measure of the opposition to current flow in an electrical circuit.

Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.

V = I × R

Where;

V is the voltage or potential difference. I is the current.R is the resistance.

The unit of the electrical resistance is ohm Ω

The symbol of resistance is R.

Hence Option A) Symbol: R, Unit : Ω is the correct answer
