The two different mineral elements that a fertilizer can contain are:

Phosphorus - build up of nucleic acid and ATP
Nitrogen- synthesis of proteins

<h3>What are fertilizers?</h3>

Fertilizers are chemical substances added to the soil in order to improve crop growth and development.

Fertilizers are artificially made to contain mineral elements that are needed by the plants. Some of the mineral elements are as follows:

Phosphorus
Nitrogen
Pottasium

Phosphorus helps in the build up of nucleic acids and ATP for energy.
Nitrogen is useful in the synthesis of proteins.

An element has an atomic number of 92 and a mass number of 234. how many neutrons does the element have? 192 142 92

GuDViN [60]

The atomic number of an element is characteristic to that element. Atomic number is the number of protons of that element.
Mass number is the sum of protons and neutrons of the element.
since protons and neutrons have a mass of 1 unit each, they together make up the mass of the element.
atomic number - number of protons - 92
mass number - number of neutrons + protons = 234
number of neutrons = mass number - atomic number
neutrons = 234 - 92 = 142
answer is 142

Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentratio

velikii [3]

<u>Answer:</u> The amount of CO that is occupied in the room is $1.98\times 10^3L$

<u>Explanation:</u>

We are given:

Concentration of CO = $8.00\times 10^2ppm=800pm$ by volume

This means that $800\mu L\text{ or }800\times 10^{-6}$ of CO is present in 1 L of blood

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 10.99 m

b = breadth of cuboid = 18.97 m

h = height of cuboid = 11.89 m

$V=10.99\times 18.97\times 11.89=2478.83m^3$

Converting this into liters, by using conversion factor:

$1m^3=1000L$

So, $2478.83m^3=2.479\times 10^6L$

Applying unitary method:

In 1 L of blood, the amount of CO present is $800\times 10^{-6}$

So, in $2.479\times 10^6L$ of blood, the amount of CO present will be = $\frac{800\times 10^{-6}}{1}\times 2.479\times 10^{6}=1983.2L=1.98\times 10^3L$

Hence, the amount of CO that is occupied in the room is $1.98\times 10^3L$

Light of a certain energy Shines on a metal and causes electrons to be emitted based on the research of Albert Einstein what cha

Butoxors [25]

According to Albert Einstein's theory of photoelectric effect, metals will only emit electrons when the incident light has a frequency that is above the minimum or threshold frequency.

So if the frequency of the incident light is less than the threshold frequency then electrons will not be emitted from that metal.

gtnhenbr [62]

In the categorization of tornadoes, most tornadoes (87%) are no stronger than EF1 unless 'most' is considered 55% in which case the answer is EF0.
EF0 - 65 to 85 mph {104.61 to 136.79 km/h}EF1 - 86 to 110 mph {138.40 km/h to 177 km/h}
Hence the answer would have to be C
