Explanation:

The process is photosynthesis as plants need carbon dioxide and humans need oxygen so plants release oxygen which humans breath/take in and plant/trees take in carbon dioxide which humans release.

The natural process which removes  carbon dioxide from the atmosphere is photosynthesis.

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Answer:

4

Explanation:

There are 4 different elements in the compound (N, H, P, O) but if you want to count the number of each element then the answer is different.

In NH4, theres 1 N and 4 H, but since there are 3 NH4s then u have 3 N and 12 H. There's 1 P and 4 Os as well.

Added together u have 3 + 12 + 1 + 4 = 20 elements in total.

B) ATP to form ADP, releasing energy.

Answer:

The speed will be 42 m/s

Explanation:

Wavelength is the minimum distance between two points on the wave that are in the same state of vibration. In other words, in a periodic wave the wavelength is the physical distance between two points from which the wave repeats.

Frequency (f) is the measure of the number of cycles or repetitions of the wave per unit of time. That is, it is the number of vibrations that occur in a unit of time. That is, how many peaks or valleys are repeated in a unit of time. If the unit of time is one second then the frequency is measured in Hertz (Hz).

The wavelength (λ) and the frequency (f) are two inversely proportional parameters and related by the propagation speed. The speed of propagation is the speed with which the wave travels, it is represented by the letter "v". The equation that links these three parameters is v = f * λ.

In this case:

Replacing:

v= 14 Hz* 3 m

Solving:

v= 42 m/s

The speed will be 42 m/s

Answer:

19.32 = moles of carbon

57.54 = moles of hydrogen

9.69 = moles of oxygen

Explanation:

232 g carbon × 1 mol C / 12.011 g C= 19.32 mol C

58 g hydrogen × 1 mol H / 1.008 g H = 57.54 mol H

155 g oxygen × 1 mol O / 15.999 g O = 9.69 mol O

Answer:

139.11 grams

Explanation:

The molarity (M) is equal to m (moles) /L (liters).

Notice how it is in mL so converting it would be 0.75 L (750*10-3)

Now plug in the information

1.75=m/0.75

m=1.3125

Now m is in moles so convert to grams to get the mass

1.3125 mol Na2CO3 * 105.9888 g Na2CO3 = 139.1103

Answer:

Let’s get back to simple physics and the laws of motion. Your car and everything in it are traveling in a given direction, to stop in requires force be applied in the opposite direction over a period of time. This occurs extremely quickly in an accident and the force is greater because the time the opposing force is acting on the vehicle is very short. The airbag system is designed to offer you protection from the violent forces exerted on you during an accident.

There are three main components to your airbag system, the bag, the inflator and the sensor. The sensor must register a collision force roughly equal to hitting a brick wall at 10 to 15 mile per hour before it will trigger the airbag inflation. Once tripped the airbag system inflates through a chemical reaction between sodium azide (NaN3) and potassium nitrate (KNO3) which creates nitrogen gas. An igniter is set off which quickly burns the chemical fuel and creates the gas needed for expansion. The bag then blows out of its storage in a split-second. Immediately after inflation, when the chemical burn is complete, the airbag begins to deflate as the gasses escape from holes in the fabric.

Explanation:

stronger gravitational gradient

Answer: 0.045 moles of [tex]F_2[/tex] will be required to  produce 3.0 grams of  [tex]KrF_6[/tex].

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} KrF_6=\frac{3.0g}{198g/mol}=0.015moles[/tex]

The balanced chemical equation is:

[tex]Kr+3F_2\rightarrow KrF_6[/tex]  

According to stoichiometry :

1 mole of [tex]KrF_6[/tex] is produced by = 3 moles of [tex]F_2[/tex]

Thus 0.015 moles of [tex]KrF_6[/tex] will be produced by=[tex]\frac{3}{1}\times 0.015=0.045moles[/tex]  of [tex]F_2[/tex]

Thus 0.045 moles of [tex]F_2[/tex] will be required to  produce 3.0 grams of  [tex]KrF_6[/tex].

A. Boyle's law: P1 V1 = P2 V2

B. Charles's law: V/T = k or V1 / T1 = V2 / T2

C. Avogadro's law: V = kn

D. Dalton's law: Ptotal = P1 + P2 + P3 + .

Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant. Charles' law is named after J. -A. -C.

Answer:

22.22 g

Explanation:

The balanced reaction equation is;

Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)

Number of moles of calcium reacted = 8.02g/40.1g/mol = 0.2 moles of Calcium

From the reaction equation;

1 mole of Ca yields 1 mole of CaCl2

Hence 0.2 moles of Ca also yields 0.2 moles of CaCl2

Mass of calcium chloride produced = number of moles * molar mass

Mass of calcium chloride = 0.2 moles of CaCl2 * 111.1g/mol = 22.22 g
