Answer:
Solar panels capture the sun's rays and convert it into heat and electricity, which is used to heat and cool your home, while geothermal solutions use the constant core temperature of the Earth to warm and cool a property.

The second reaction with the volume of 5L will occur faster as compared to the first reaction of volume 10L.
Volume is inversely proportional to the rate of reaction.
As volume increases rate of reaction decreases and as volume decreases rate of reaction increases.
Let's consider a reaction A → B.
r is rate of reaction and K is rate constant, A is the concentration of reaction.
r = k(A)
r is directly proportional to the A.
But the concentration of A is in Moles/liters (i.e. moles per unit volume)
r is inversely proportional to the volume of vessel or chamber.
Hence as volume increases rate of reaction decreases.

Answer:
Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

Answer:
1.27 atm is the final pressure of the oxygen in the flask (with the stopcock closed).
2.6592 grams of oxygen remain in the flask.
Explanation:
Volume of the flask remains constant = V = 2.0 L
Initial pressure of the oxygen gas = 
Initial temperature of the oxygen gas = 
Final pressure of the oxygen gas = 
Final temperature of the oxygen gas = 
Using Gay Lussac's law:
1.27 atm is the final pressure of the oxygen in the flask (with the stopcock closed).
Moles of oxygen gas = n
(ideal gas equation)
Mass of 0.08310 moles of oxygen gas:
0.08310 mol × 32 g/mol = 2.6592 g
2.6592 grams of oxygen remain in the flask.
Hey there!
Organic acid present in the methylene chloride when treated with aqueous NaOH it will be converted to aqueous soluble sodium carboxylate salt as shown below :
RCOOH (DCM layer) + NaOH ----------------> RCOONa (aqueous layer) + H₂O
the organic layer methylene chloride is immiscible with water, therefore it will present as two-layer, the large denser layer will present at the bottom
Density of dichloromethane = 1.325 g/mL
Density of water = 1 g/mL
Since dichloromethane density is more it will present at the bottom and water density is lesser, therefore, it will present its top, since RCOONa is aqueous soluble it present at the top aqueous layer
*Organic acid will present in the top layer
