Can someone convert 150 cm of copper (Cu) wire into mm of Cu wire?​
Vedmedyk [2.9K]

1500 mm of copper wire are produced by converting 150 cm of copper wire.

The following is the centimeter to millimeter conversion factor: 1 cm is equivalent to 10 mm.

Consequently, 150 cm will equal 150 x 10 = 1500 mm.

  • The multi-step process of unit conversion involves multiplying or dividing by a numerical factor.
  • Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
  • Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor.
  • The process may also require the selection of the correct number of significant digits, and rounding.

VLD [36.1K]

Answer:

i dont even know tbh jk i wont waste ur time unless nvm ok so the answer is The correct answer would be C.10. Krebs cycle is a part of cellular respiration that takes place in the mitochondria. Five energy conversions take place in one complete cycle of the Krebs cycle. These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.

What is the mass of 4.40 moles of magnesium chloride, MgCl2?
Darya [45]
Since the number of moles of a substance is the mass divided by the molar mass of the substance, we can just simply multiply the molar mass of magnesium chloride by the number of moles, which is 4.40 in this case.

To find the molar mass, refer to the periodic table for the relative atomic mass of Mg and Cl and add them together. Since there’s 2 chloride ions in MgCl2, double the relative atomic mass of Cl when adding.

24.31 + 35.45x2
=95.21

Now just multiply 95.21 to 4.40mol, which you’ll get 418.9g (corrected to 3 significant figures)

Answer:

42 = f = 1.02 × 10¹⁶ s⁻¹

43 =  λ= 1.1 × 10⁻¹² m.

44 = Average atomic mass of Z = 19.864 amu.

45 = Average atomic mass of Mg = 24.323 amu.

46= Electronic configuration:

     P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³

Explanation:

Q 42 = What is the frequency of ultraviolet light with wavelength 2.94 × 10⁻⁸ m.

Given data:

wavelength of radiation = 2.94 × 10⁻⁸ m.

Speed of light = 3 × 10⁸ m/s

Frequency = ?

Solution:

Formula:

speed or velocity = wavelength × frequency

c = λ × f

f = c/ λ

f = 3 × 10⁸ m/s /2.94 × 10⁻⁸ m.

f = 1.02 × 10¹⁶ s⁻¹

43 = what is the wavelength of gamma ray with the frequency 2.73 × 10²⁰ Hz.

Given data:

wavelength of radiation = ?

Speed of light = 3 × 10⁸ m/s

Frequency = 2.73 × 10²⁰ Hz.

Solution:

Formula:

speed or velocity = wavelength × frequency

c = λ × f

λ = c / f

λ = 3 × 10⁸ m/s /2.73 × 10²⁰ s⁻¹

λ= 1.1 × 10⁻¹² m.

So the wavelength of gamma radiation is 1.1 × 10⁻¹² m.

44= Consider an element Z that has two natural occuring elements with the following percent abundances: the isotope with the mass number of 19.0 is  56.8% abundant and the isotope with mass number of 21 is 43.2% abundant. what is average atomic mass of elements Z.

Given data:

Abundance of 1st isotope = 56.8%

Abundance of second isotope = 43.2%

Atomic mass of 1st isotope = 19 amu

Atomic mass of second isotope = 21 amu

Average atomic mass = ?

Solution:

Average atomic mass of carbon = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass of Z = (19.0 × 56.8) + (21  ×43.2) /100

Average atomic mass of Z=  1079.2 + 907.2 / 100

Average atomic mass of Z = 1986.4 / 100

Average atomic mass of Z = 19.864 amu.

45 = What is the atomic mass of Mg if the natural occuring isotopes are Mg-24, 78.70%

Mg-25, 10.13%

Mg-26, 11.17%

Given data:

Abundance of Mg²⁴ = 78.70%

Abundance of Mg²⁵ = 10.13%

Abundance of Mg²⁶ = 11.17%

Average atomic mass = ?

Solution:

Average atomic mass of Mg = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) +( abundance of 2nd isotope × its atomic mass) / 100

Average atomic mass of Mg = (24 × 78.70) + (25× 10.13) + (26 × 11.17) /100

Average atomic mass of Mg=  1888.8 + 253.25 + 290.42 / 100

Average atomic mass of Mg = 2432.47 / 100

Average atomic mass of Mg = 24.323 amu.

Q = 46= What is electronic configuration for phosphorus?
