HELPPP PLEASEEEEEE DUE TODAY :(

Answer:

carbon-14 or carbon-6, sorry i'm not sure which one.

Explanation:

For example, carbon-12 has 6 protons and 6 neutrons and carbon-13 has 6 protons and 7 neutrons and both are stable isotopes, where as carbon-14 (a radioactive isotope) has 6 protons and 8 neutrons and will decay (Fig. 1).

Answer:

true All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis. ... So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!

Question: Next, click the Glass Layers tab in the black bar at the bottom of the simulation. Use the arrow in the Options field on the right to add one or more glass panes. This simulation shows how different photons would react to a layer of glass surrounding Earth, much like an actual greenhouse. How do the sunlight photons and infrared photons react differently to the glass layer(s)?

Edmentum answer:  The visible light photons pass through the glass unaffected. However, the infrared photons that Earth reflects often change direction or are absorbed back into Earth’s surface when they interact with the glass.

the greenhouse keep plants warm because allow the heat to be retained, the gases provide the heating of the Earth.

The operation of greenhouses is very simple: the sun's rays pass through the roof and heat the ground, and when the heat rises, it is not dissipated, remaining in the environment because it is trapped by the roof.

The denomination of greenhouse or shelter is used when the objective is to heat the environment. This technique is important as some plants do better in warmer temperatures. Cold can cause poor seed germination and poor nutrient absorption.

Answer:

The kinetic theory of matter explains that all matter is made of particles which are constantly moving/have energy. The energy varies depending on the temperature of the matter, therefore determining if the matter is solid, liquid, or gas. When the energy of a particle is increased or decreased, a phase change can occur.

Answer:

Yeah, probably population.

Explanation:

Population as in the species' population.

Answer:

Snow forms when the atmospheric temperature is at or below freezing, and there is a minimum amount of moisture in the air. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain

Explanation:

When water vapor cools and condenses forms clouds, that is, return to water or rain.

When the temperature in the atmosphere is at or below freezing 0 degrees Celsius and there is a minimal amount of moisture in the air, snow forms.

Clouds are formed by evaporating water or ice from the Earth's surface, or by plants releasing water and oxygen as a result of photosynthesis.

Water evaporates, or rises from the Earth's surface into the atmosphere, creating a gas called water vapor.

When water vapor cools and condenses—that is, returns to liquid water or ice—it forms clouds.

A significant snowstorm or blizzard requires three factors:

Thus, these are the conditions for snow and rain.

Answer:

26

because it just is

Answer:

Explanation:

Remember that the key is the water so

using the formula q=m*s*deltT

We have the mass 2000g

we have the specific heat of water which is 1.00 cal/ g C

and the final temperature 20 C

Remember that delt T is the change in temperature meaning (Tfinal - Tinitial) Assuming that the water is at room  temperature (25 C)  before starting the reaction then

q= (2000 g)(1.00 cal/g C)(20-25)

q= -10, 000 cal  

if you want you can convert to joules by multiplying by 4.314 J

In more simpler terms - If all the heat released was absorbed by the water, and it takes 1 calorie of heat to raise

the temperature of 1 gram of water by 1°C that is a total of 20 times 2000 or 40,000 cal.

or 40 kilocalories. If you want it in joules, there are 4.184 joules to one calorie so it is

4.184 times 40 or 167.36 kilojoules.

A snack that, when burned, heats 2,000 g of water by 20 °C, releases 4.0 × 10⁴ cal (1.7 × 10⁵ J).

A snack bar is burned in a calorimeter and heats 2,000 g  (m) of water by 20 °C (ΔT).

We can calculate the heat absorbed by the water (Qw) using the following expression.

[tex]Qw = c \times m \times \Delta T = \frac{1cal}{g.\° C } \times 2,000 g \times 20 \° C = 4.0 \times 10^{4} cal[/tex]

where,

According to the law of conservation of energy, the sum of the heat absorbed by the water (Qw) and the heat released by the combustion (Qc) is zero.

[tex]Qw + Qc = 0\\\\Qc = -Qw = -4.0 \times 10^{4} cal[/tex]

Finally, we can convert -4.0 × 10⁴ cal to J using the conversion factor 1 cal = 4.18 J.

[tex]-4.0 \times 10^{4} cal \times \frac{4.18 J}{1cal} = 1.7 \times 10^{5} J[/tex]

Answer

yes

Explanation:

the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.

Answer:

Particles become sorted on the basis of density, because of the energy of the transporting medium. High energy currents can carry larger fragments. As the energy decreases, heavier particles are deposited and lighter fragments continue to be transported. This results in sorting due to density.

i hope this will help u

pls add me as brainliest

Answer:

hope this helps

Explanation:

A conductor is a substance that quickly transmits energy, whereas an insulator is a material that resists energy transfer. Because there are numerous sorts of energy, there are different types of conductors and insulators. Electrical conductors are materials that conduct electrons, protons, or ions. Electrons in electrical conductors are usually loosely bonded. Thermal conductors are materials that conduct heat. Acoustic conductors are substances that transfer sound. Each type of conductor has a corresponding insulator.
