Another type of weathering that attacks rocks is chemical weathering, a process that breaks down rock through chemical changes. The causes of chemical weathering include action of water, oxygen, carbon dioxide, living organisms, and acid rain. Chemical weathering can produce new minerals as it breaks down rock.

Explanation:

The stable nuclei can be identified if the count of proton and neutron are same then nuclei will be stable.

That kind of nuclei which posses identical number of proton and neutron as well can be referred as stable nuclei. For example: The isotope of carbon [tex]C^{12}[/tex] has 6 proton and 6 neutron as well. Hence it might be considered as stable nuclei.

A hydrogen atom's nucleus contains positively charged protons. Protons, electrons, as well as neutrons, make up an atom.

Answer:

Study the bone structure of limbs.

Explanation:

Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.

Use Charles' Law: V1/T1 = V2/T2. We assume the pressure and mass of the helium is constant. The units for temperature must be in Kelvin to use this equation (x °C = x + 273.15 K).

We want to solve for the new volume after the temperature is increased from 25 °C (298.15 K) to 55 °C (328.15 K). Since the volume and temperature of a gas at a constant pressure are directly proportional to each other, we should expect the new volume of the balloon to be greater than the initial 45 L.

Rearranging Charles' Law to solve for V2, we get V2 = V1T2/T1.  

(45 L)(328.15 K)/(298.15 K) = 49.5 ≈ 50 L (if we're considering sig figs).

parts per million are defined as the mass of solute in mg (In this case, mass of DDT) per kg of sample.

To solve this question we must find the mass of DDT in mg and the mass of sample in kg:

Mass DDT:

0.10g * (1000mg / 1g) = 100mg

Mass sample:

5000g * (1kg / 1000g) = 5kg

Parts per Million:

US. With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

Answer:

The thermal energy (heat) needed, to raise the temperature of oil of mass  'm' kilogram and specific heat capacity 'c' from 20°C to 180°C  is  160·m·c joules

Explanation:

The heat capacity, 'C', of a substance is the heat change, ΔQ, required by a given mass, 'm', of the substance to produce a unit temperature change, ΔT

∴ C = ΔQ/ΔT

ΔQ = C × ΔT

C = m × c

Where;

c = The specific heat capacity

ΔT = The temperature change = T₂ - T₁

∴ ΔQ = m × c × ΔT

Therefore, the thermal energy (heat) needed, ΔQ, to raise the temperature of oil of mass 'm' kilogram and specific heat capacity, 'c' from 20°C to 180°C  is given as follows;

ΔQ = m × c × (180° - 20°) = 160° × m·c

ΔQ = 160·m·c joules

A solute is a substance that is dissolved in another substance (option A).

A solute is any substance that is dissolved in a liquid solvent to create a solution.

This means that a solute + solvent = solution. For example; sugar (solute) is dissolved in water (solvent) to form a sugary solution.

Therefore, a solute is a substance that is dissolved in another substance.

Answer:

Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.

Explanation:

Kinetic energy is the speed of the particles in the bottle.

As you can see in the illustration below, the patricles in Picture 2 are moving faster than the ones in Picture 1.

The tempature of Container 1 is higher because all of the particles are sitting on top of one another. Not being able to move, their pressure builds up and creates heat.

Answer:

0.00331M

Explanation:

Molarity of a solution can be calculated as follows:

Molarity = number of moles (n) ÷ volume (V)

In the information provided in this question, the volume = 502mL = 502/1000 = 0.502L, mass of caffeine = 0.322g

Molar mass of caffeine (C8H10N4O2), where C = 12, H = 1, N = 14, O = 16 is as follows:

Molar mass = 12(8) + 1(10) + 14(4) + 16(2)

= 96 + 10 + 56 + 32

= 194g/mol

Using, moles = mass/molar mass

moles = 0.322/194

moles = 1.66 × 10-³ moles

mole = 0.00166mol

Molarity = number of moles ÷ volume

Molarity = 0.00166mol ÷ 0.502L

Molarity = 0.00331M.

Answer:

Explanation:

For a given substance, the molar heat of fusion basically tells you one thing from two perspectives

how much heat is needed in order to melt one mole of that substance at its melting point

how much heat must be removed in order to freeze one mole of that substance at its freezing point

It is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.

Answer:The video shows the electric circuit inside a flashlight. The battery provides power to the circuit. A metal strip is connected to the negative end of the battery. When the flashlight’s switch is pressed, the metal strip moves forward. It touches the metal connected to the bulb near the front. This motion closes the circuit, which creates a path for the electricity and causes the bulb to glow.
