Answer: The answer is YES. There would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use.
Explanation:
Carbon is an element in the periodic table with the atomic number of 12. It has 4 electrons on its outermost shell in the electronic configuration. These are valence electrons which are used to form bonds in a wide range of both organic and inorganic compounds, giving rise to simply molecules like carbondioxide.
CARBON CYCLE is a natural process through which carbon and it's compounds are kept fairly constant through recycling. They are found in fossils fuels such as oil, coal, and natural gas. When these fossil fuels are burnt and used as energy, carbon is released in form of carbondioxide. This is just one of the ways carbon is returned to the atmosphere. Other ways include:
--> respiration of plants and animals
--> decomposition of organic substances
--> action of dilute acids and heat on trioxocarbonates (V) and hydrogen trioxocarbonates (IV).
Carbon is then removed from the atmosphere through:
--> plants in photosynthesis
--> rain water as weak trioxocarbonate (IV) acid.
Therefore, there would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use because the burning of fossil fuels is not the only way carbon is returned to the atmosphere during carbon cycle.

Assume that you have to prepare a 200 g salt solution, and the concentration must be 15 % by mass. How many grams of solute and water you must mix together.
Answer:
170 g
Explanation:
w/w% concentration = mass of solute/ mass of solution * 100
mass of solute = x
mass of solution = 200 g
w/w% concentration = 15 % by mass
15 = x/200 * 100
15 = 100x/200
200 * 15 = 100x
x = 200 * 15/100
x = 2 * 15
x = 30g
But mass of solution = mass of solute + mass of solvent
mass of solute = 30g
mass of solvent = mass of solution - mass of solute
mass of solvent = 200 g - 30 g
mass of solvent = 170 g

Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.
What is soil?The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of elements such as carbon through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.
It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. A practical understanding of soils including their management has also developed out of need since the development of agriculture with forestry in the eighth millennium BCE.

Using the information in the passage, rank the types of galaxies by their ability to form new stars, from most to least activity.
Answer:
The correct answer is number 2. Elliptical, Spiral, Irregular.
Explanation:
Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.
So we are going to answer this question with our own knowledge.
The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."
That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.
Scientists still studying the universe and the galaxies to understand the way galaxies are formed.

Answer:
B. Radiation
Explanation:
Lol this weekend I got a rlly bad sunburn and ik a lot ab the sun
The method of heat transfer occurs when your skin feels hot outside on a sunny, summer day is radiation. Therefore, option B is correct.
What is radiation ?Energy that emanates from a source and moves through space at the speed of light is referred to as radiation. This energy has wave-like qualities and is accompanied by an electric field and a magnetic field. Radiation may also be referred to as electromagnetic waves.
As a mutagen, radiation has the potential to eventually cause cancer. Radiation has the power to kill cells or harm the DNA within them, which impairs the cells' capacity for reproduction and may ultimately result in cancer. High energy particles flow through your body when radiation is present.
The DNA in our cells can be harmed by radiation. Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries can result from high radiation doses (CRI). Cancer may develop later in life as a result of high radiation doses.
Thus, option B is correct.

Benzoic acid contains 68.8% carbon, 4.95% hydrogen, and 26.25% oxygen. Find the empirical formula of benzoic acid.
Answer:
C7H6O2
Explanation:
Let;
68.8% of Carbon represents 68.8g
4.95% of Hydrogen represents 4.95g
26.25% of Oxygen represent 26.25g
Next, we convert each gram value to mole value by dividing by their respective molar mass {C = 12, H = 1, O = 16}
C = 68.8/12 = 5.73 mol
H = 4.95/1 = 4.95 mol
O = 26.25/16 = 1.64 mol
Next, we divide each mole value by the smallest (1.64mol)
C = 5.73 ÷ 1.64 = 3.49
H = 4.95 ÷ 1.64 = 3.02
O = 1.64 ÷ 1.64 = 1
Next, we multiply each ratio by 2 to obtain our simplest whole number ratio (empirical formula)
C = 3.5 × 2 = 7
H = 3.02 × 2 = 6
O = 1 × 2 = 2
Hence, the ratio of C, H and O is 7:6:2 and the empirical formula of benzoic acid is C7H6O2
