Answer:

multiple voltaic cells that have spontaneous half reactions

Explanation:

A battery is an electrochemical device that stores energy. This is connected to an electrical circuit, and chemical energy is transformed into electrical energy. All are similar in construction, each of these cells is composed of a positive and a negative electrode in addition to a separator. When the battery is discharged, an electrochemical change occurs between the different materials in the two electrodes. The electrons are transported between the positive and negative electrodes through an external circuit (light bulbs, starter motors, etc.)

A 1.00 L volume of HCl reacted completely with 2.00 L of 1.50 M Ca(OH)2 according to the balanced chemical equation below. 2HCl

wolverine [178]

Answer:

$\boxed{\text{6.00 mol/L}}$

Explanation:

(a) Balanced equation

2HCl + Ca(OH)₂ ⟶ CaCl₂ + 2H₂O

(b) Moles of Ca(OH)₂

$\text{Moles of base} = \text{2.00L} \times \dfrac{\text{1.50 mol}}{\text{1 L}} = \text{3.000 mol base}$

(c) Moles of HCl

$\text{Moles of HCl} = \text{3.000 mol base} \times \dfrac{ \text{2 mol HCl}}{\text{1 mol base}} = \text{6.000 mol HCl}$

(d) Molar concentration of HCl

$\text{Molar concentration} = \dfrac{\text{moles of solute}}{\text{litres of solution}}\\\\c = \dfrac{ n }{ V}\\\\c= \dfrac{ \text{6.000 mol}}{ \text{1.000 L}} = \text{6.00 mol/L}$

The molar concentration of the HCl was $\boxed{\textbf{6.00 mol/L}}$

After an afternoon party, a small cooler full of ice is dumped onto the hot ground and melts. If the cooler contained 6.60 kg of

gtnhenbr [62]

Answer:

The quantity of heat required to melt all the ice at 0°C is 2.21 * 10⁶ J

Explanation:

Latent heat of fusion is the heat absorbed by a unit mass of a given solid at its melting point that completely converts the solid to a liquid at the same temperature. Its unit is Joules/kg or Joules/g.

1 calorie = 4.184 Joules

Therefore , 80.0 cal/g = 80.0 cal/g * 4.184 J/cal = 334.72 J/g

1 g = 0.001 kg; Heat of fusion in J/kg = 334.72 J/g * 1g /0.001 kg = 3.35 * 10⁵ J/kg

Quantity of heat, Q = mass * latent heat of fusion of ice

quantity of heat required = 6.60 kg * 3.35 * 10⁵ J/kg

Quantity of heat required = 2.21 * 10⁶ J

Therefore, the quantity of heat required to melt all the ice at 0°C is 2.21 * 10⁶ J

What is needed for our cells to get energy from our food?

denis-greek [22]

Answer:

cellular respiration is needed for our cells to get energy from our food.

Explanation:

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
