Answer:

Both temperature and pressure increase as you get closer to the Earth's centre.

Explanation:

The pressure increases as you go deeper because there is always more weight from above.

The pressure goes from 1 atm at the surface to 3.5 × 10⁶ atm in the core.

The core is hot because of

residual heat from when the Earth was formed
the energy released by decay of radioactive elements.

Here’s a table of approximate temperatures in the various layers.

Layer T/°C

Crust 300

Upper mantle 1300

Lower mantle 3300

Outer core 4500

Inner core 6000

Ppredict the identity of the precipitate in the below reaction: BaCl2(aq) + K2SO4(aq) →

Annette [7]

Answer: The precipitate formed is $BaSO_4$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

$K_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2KCl(aq)$

A certain gas is present in a 13.0 l cylinder at 4.0 atm pressure. if the pressure is increased to 8.0 atm , the volume of the g

ella [17]

Boyle's Law is k = PV so Initial k = 13.0 L x 4.0 atm = 52 L atm Final kf = 6.5 L x 8 atm = 52 L atm The gas obeys Boyle's Law The answer with two significant figures separated by a comma is k = 52, kf = 52.

A solution was made by dissolving 5.10 mg of hemoglobin in water to give a final volume of 1.00 ml. the osmotic pressure of this

Assoli18 [71]

The molecular weight of hemoglobin can be calculated using osmotic pressure

Osmotic pressure is a colligative property and it depends on molarity as

πV = nRT

where

π = osmotic pressure

V = volume = 1mL = 0.001 L

n = moles

R = gas constant = 0.0821 L atm / mol K

T = temperature = 25°C = 25 + 273 K = 298 K

Putting values we will get value of moles

$moles=\frac{\pi V}{RT}=\frac{0.00195X0.001}{0.0821X298}mol$

we know that

$moles=\frac{mass}{molarmass}$

Therefore

$molarmass=\frac{mass}{moles}=\frac{5.10X10^{-3}g}{7.97X10^{-8}}=6.399X10^{4}g$

Why is water a polar molecule but a fluorine molecule is not?

yKpoI14uk [10]

Answer:

The electrons in H2O are not shared equally, making it a polar molecule. The molecules in flourine, F2, are shared equally, making it not a polar molecule.
