Answer:

Explanation:

When you use electricity to charge your car, you can integrate renewable resources like solar into the fueling process. Without solar, your electric vehicle is still effectively running off of fossil fuels – it's just the fossil fuels utilized at the power plant and not within your engine.

When ice is melting, the heat being added causes:

In-s [12.5K]

Explanation:

Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. Even though the water's physical form changes, its molecules stay the same.

Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O) to form 10 molecules of carbon dioxide (CO2CO2). According to t

elena-s [515]

Answer:

According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.

LAW OF CONSERVATION OF MATTER:

The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.

This further means that the amount of matter in the reactant of a reaction must equate that of the products.

Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.

Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.

Two electrons are found in the same atom. One electron has the quantum number set (4, 1, 0, +½), and the other electron has the

Kruka [31]

Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.

You are burning wood to heat water for your industrial process. What is the mass of wood required to raise the temperature of 10

natta225 [31]

Answer:

18,8kg of wood

Explanation:

The energy you need to to raise the temperature of 1000 kg of water from 25.0 to 100.0 °C is:

q = C×m×ΔT

Where: q is heat, C is specific heat of water (4,184J/g°C), m is mass in grams (1000x10³g), and ΔT is 100,0°C - 25,0°C = 75,0°C

Replacing:

q = 4,184J/g°C×1000x10³g×75,0°C

q = 3,14x10⁸ J of heat are required

Now, if the heating value of dry wood is 16,72 MJ/kg = 16,72x10⁶ J/kg, mass of wood required is:

3,14x10⁸J × (1kg / 16,72x10⁶ J) = 18,8 kg of wood are required

I hope it helps!
