Spell out the full name of the compound.

Part B

Spell out the full name of the compound.

Part C

Spell out the full name of the compound.

Part D

Spell out the full name of the compound.

IUPAC naming:

In organic chemistry, chemical compounds are named by a standardized method known as the IUPAC system. These four examples are all hydrocarbons with double and triple bonds. The names of the compounds are based on the length of the carbon chain, the position of the double or triple bonds and the position of any carbon groups branched off of the main chain.

Which example describes how the water cycle carries on energy transfer? a flooding river depositing silt on a floodplain a warm

Irina18 [472]

Answer:

The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

LenKa [72]

Answer: b) Doppler Effect

Explanation:

Line broadening in AAS, arises due to some effects, which can occur due to a number of factors. The line width broadening effects include: Doppler, Lorentz, Self absorption, and quenching effects.

Doppler effect arises because along the line of observation, atoms will have different components of velocity.

What are the five rules for significant figures? Give some examples

Lapatulllka [165]

"There are three rules on determining how many significant figures are in a number: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant."

Pls tell me how to solve this!

Anna35 [415]

Answer:

12 seconds

Explanation:

Time taken by 50cm³ of oxygen to diffuse from pinhole

= 1 minute = 60 seconds

⠀

$\textsf{ Rate of oxygen} \sf (O_2) = \frac{50}{60}$

⠀

Let time taken by 50cm³ of hydrogen to diffuse from pinhole = t seconds

⠀

$\textsf {Rate of hydrogen } \sf(H_2) = \frac{50}{t}$

⠀

According to the formula

$\sf \frac{Rate \: of \: hydrogen(H_2)}{Rate \: of \: oxygen(O_2) } = \sqrt{ \frac{Molar \: mass \: of \: O_2}{Molar \: mass \: of \: H_2} }$

⠀

$\large \sf \frac{50}{t} \div \frac{50}{60} = \sqrt{ \frac{\cancel{32}\small 16}{\cancel2} } \\ \\ \sf \large \frac{ \cancel{50}}{t} \times \frac{60}{ \cancel{50}} = \sqrt{16} \\ \\ \sf \large \frac{60}{t} = 4 \\ \\ \sf \large \frac{ \cancel{60} \: \small12}{ \cancel4} = t \\ \\ \large \underline{ \boxed{ \tt t = 12 \: seconds}}$

⠀

<h3>Henceforth, the time taken by 50cm³ of hydrogen to diffuse is 12 seconds. </h3>

⠀

<h2>Thank you!</h2>

Answer: The expression of $K_{sp}$ for calcium fluoride is $K_{sp}=[Ca^{2+}][2F^-]^2$

Explanation:

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

The given chemical equation follows:

$CaF_2\rightleftharpoons Ca^{2+}(aq.)+2F^-(aq.)$

1 mole of calcium fluoride produces 1 mole of calcium ions and 2 moles of fluorine ions.

The expression of $K_{sp}$ for above equation follows:

$K_{sp}=[Ca^{2+}][2F^-]^2$

Hence, the expression of $K_{sp}$ for calcium fluoride is $K_{sp}=[Ca^{2+}][2F^-]^2$
