Nitrogen can be converted to both biological and chemical ways. Why is nitrification an important process? 1. Bacteria converts ammonia into nitrites and nitrates that plants can use. 2. Fungi convert nitrogen in dead plants into ammonium which converts proteins into ammonia. 3. Nitrogen is converted into a usable form through lightning fixation. 4. Plant enzymes reduce nitrogen compounds into amino acids.
Answer:
it is option A
Explanation: nitrification, is the process by which bacteria in the soil convert ammonia to nitrites and nitrates. Ammonia (NH3) was produced by nitrogen fixation, but plants prefer nitrites and nitrates as a source of nitrogen and oxygen.

What is one thing rock, air and water all have in common
Answer: all can be affected by the natural environment ( not sure answer hope it helped)
Explanation:
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, rock, air and water all are matter.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Rock, air and water all are matter.
Therefore, rock, air and water all are matter.

Explanation:
In covalent bonding, atoms share electrons from their last shell to other atoms to gain stability.
Chlorine has 7 electrons in its last shell, it needs to gain 1 electron to become stable.
Group 1 elements have 1 electron in their last shell, they need to lose 1 electron to become stable.
Group 1 elements can bond with chlorine.
Katherine was given a tiny lamb by her uncle. The lamb was a runt and had to be fed by hand. Every 3 hours
Katherine had to give it 290 milliliters of milk. How much milk, in LITERS, will the lamb get in 24 hours?
Answer:
2.32 liters
Explanation:
you would just divide 24 by 3 which is 8 and multiply 290 by it which is 2320 and divide by 1000 which is 2.32
The quantity of milk that will the lamb give in 24 hours is 2.32 Liter.
What is a Lamb?Lamb may be defined as the youngest form of sheep. In other words, it may be characterized as the little offspring produced by a sheep.
According to the question,
The amount of milk given by lamb in three hours = 290 milliliters.
∴ The amount of milk given by lamb in one hour = 96.66 milliliters.
Now, the amount of milk given by a lamb in 24 hours = 24 × 96.66 = 2320 milliliters.
Now, as per the requirement of the question, convert milliliter into liter.
One liter = 1000 milliliters.
∴2320 milliliters = 2320/1000 = 2.32 liters.
Therefore, the quantity of milk that will the lamb give in 24 hours is 2.32 Liter.

What is the mass of an rock that has a density of 3.52 g/cc. and when put in a graduated cylinder with 50ml of water makes the level rise to 62ml.
Answer:
m = 42.24 grams
Explanation:
Given that,
The density of the mass of a rock is 3.52 g/cm³.
Initial volume of the graduated cylinder is 50 mL and when rock is put in it the water level makes the level rise to 62 mL.
We need to find the mass of the rock.
Volume of rock = final volume - initial volume
Volume of rock = 62 mL - 50 mL
Volume of rock = 12 mL
1 ml = 1 cm³
So, 12 mL = 12 cm³
Density=mass/volume
[tex]m=d\times V\\\\m=3.52\ g/cm^3\times 12\ cm^3\\\\m=42.24\ g[/tex]
So, the mass of the rock is 42.24 grams.
The mass of the rock is 42.24 g
We'll begin by calculating the the volume of the rock.
Volume of water = 50 mL Volume of water + rock = 62 mL Volume of rock =?Volume of rock = (Volume of water + rock) – (Volume of water)
Volume of rock = 62 – 50
Volume of rock = 12 mL
Finally, we shall determine the mass of the rock.
Volume of rock = 12 mLDensity of rock = 3.52 g/cm³ = 3.52 g/mLMass of rock =?
Mass = Density × Volume
Mass of rock = 3.52 × 12
Mass of rock = 42.24 g

A cubic container is filled up with an unknown liquid whose density is 0.180 g/cm3. The side lengh of the container is 5.00cm. Whaf is the mass of this liquid??
Answer:
22.5
Explanation:
M=D*V
V=5*5*5=125
M=0.180*125= 22.5
The mass of the liquid is 22.5 g.
A cubic container has a side length (l) of 5.00 cm. We can find the volume of the cube occupied by the liquid using the following expression.
[tex]V = l^{3} =(5.00cm)^{3} =125 cm^{3}[/tex]
We have 125 cm³ of a liquid with a density of 0.180 g/cm³. The mass of the liquid is:
[tex]125 cm^{3} \times \frac{0.180g}{cm^{3} } = 22.5 g[/tex]
The mass of the liquid is 22.5 g.

a. 313, 000 kPa
b. 0.117 kPa
c. 0.542 kPa
d. 54.9 kPa
Answer:
d. 54.9 kPa
Explanation:
mmHg and Pa are units of pressure used in chemistry principally in the study of gases. 1mmHg is equal to 133.322Pa. 412mmHg are:
412 mmHg * (133.322Pa / 1mmHg) = 54929 Pa

Change 6.03x107 to standard notation
Answer:
The answer is 60300000
Explanation:
The standard notation is the counterpart of the scientific notation, while the scientific notation tries to make the number smaller by using exponential numbers with base 10, the standard notation leaves them as whole numbers or decimal numbers.
Example: 5x10∧3 is written in standard notation as 5000; Where 3 tells us the amount of 0 that follows the whole number.
2.05x10∧2 is = 205 in standard notation; Where the 2 tells us the number of times the comma is moved to the right.

Which can lead scientists to change a theory that has already been accepted? Check all that apply. changes to scientific laws new experimental methods new hypotheses technological inventions repetitions of old experiments
Answer:
New experimental methods
Technological inventions
Explanation:
A scientific theory is usually not based on speculation. Scientific theories must have a solid empirical basis.
However, experimental methods are limited to the caliber of equipments available at the time in which a theory is formulated. With advancing years, more technological sophistication leads to the invention of new instruments and ultimately, the development of new experimental methods.
These innovations are likely to alter existing scientific theories as new evidences emerge, hence the answer.
