The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.

What can be created with differential weathering

Afina-wow [57]

rocks weather at different rates and in different ways. Rocks may be more or less susceptible to weathering because of such things as composition or induration, the hardening of a rock through processes like increased temperature of formation, pressure of formation or cementation of particles by precipitated minerals.

An Sulfur tetrafluoride gas is collected at 23.0 °C in an evacuated flask with a measured volume of 20.0 L. When all the gas has

Jlenok [28]

mass = 20.48 g

moles=0.1895

<h3>Further explanation</h3>

In general, the gas equation can be written

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.08205 L.atm / mol K

T = temperature, Kelvin

P=0.23 atm

V=20 L

T=23+273=296 K

$\tt n=\dfrac{PV}{RT}=\dfrac{0.23\times 20}{0.082\times 296}=0.1895$

mass SF₄ (MW=108,07 g/mol) :

$\tt 0.1895\times 108,07 g/mol=20.48~g$

Calculate the amount of heat energy required to convert 55.0 g of water at 62.5°C to steam at 124.0°C. (Cwater = 4.18 J/g°C; Cst

Grace [21]

Answer:

= 135,647.65 Joules or 135.65 kJ

Explanation:

Heat require to raise the temperature of 55 g water from 62.5°C to 124.0°C will be calculated in steps;

Step 1; heat required to raise water from 62.5°C to 100 °C

Heat = 55 g × 4.18 J/g°C × (100 -62.5)

= 8,621.25 Joules

Step 2; Heat required to convert water to steam without change in temperature;

Heat = moles × Molar Latent heat of vaporization.

= (55g / 18 g/mol)× 4.07 ✕ 104 J/mol

= 12.436 × 10^4 Joules

Step 3: Heat required to raise the temperature of steam from 100°C to 124 °C.

Heat = mass × specific heat capacity × ΔT

= 55 g × 2.02 J/g°C × (124-100)

= 2,666.4 Joules

Therefore; total amount of heat required is;

= 8,621.25 J + 124360 J + 2,666.4 J

<u> = 135,647.65 Joules or 135.65 kJ</u>

the relationship between the heated air particles inside a hot air balloon and the cooler air outside the balloon?

Tamiku [17]

The heated air temperature from inside the balloon more likely rises since it can't escape its trapped resulting in different density from the cooler air, the cooler air from the outside is a bit denser than the heated.

Is alka seltzer and acid or a base or netural

fiasKO [112]

Answer:

Base

Explanation:

Why is Alka-Seltzer a base?

Alka-Seltzer contains sodium bicarbonate and citric acid. The sodium citrate acts as an antacid. Excess sodium bicarbonate from the Alka-Seltzer acts to neutralize base.
