A greenhouse is filled with air that cotains more carbon dixoide than normal air has. How might phothsyphness and plant growth be affeacted

Answers

Answer 1

Answer:

See explanation

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as  in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.

What is a compound ?

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Which of the following compounds, sodium bicarbonate or water, should be used to extinguish a grease fire?

Answers

Answer:Douse the fire with baking soda: The chemical compound sodium bicarbonate, commonly called baking soda, is effective for extinguishing this type of fire. It takes a lot of baking soda to smother a grease fire, so pour it on while the flames are still small for the greatest effect

Explanation:

The grease fire has been put down by the addition of sodium bicarbonate as the extinguisher.

Grease fire has been defined as the fire that has been started with the over heating of the cooking oil at home. The fire has been started with the burning of the flammable liquids.

Extinguishing Grease fire

The fire in the cooking oil has been controlled with the addition of the sheet over the fire and turning off the flame.

The addition of water to grease fire results in the splashing of water over the fire and the spreading, resulting in the hazardous effects.

What is the state change of a gas to a liquid is called?

Answers

It is called condensation

Answer:The process in which a gas changes to a liquid is called condensation. Other examples of condensation are shown in Figure below. A gas condenses when it is cooled below its boiling point.

Explanation:

There are 4 phases for h20 solid liquid vapour and gas.

In the vacuum of space there are only 2 phases solid and gaseous, both liquid and vapour cannot exist in the absolute freezing temperature of the vacuum of space and crystalise instantly.

Watch a space shuttle dump water in space and it instantly freezes, and when in direct sunlight instantly turn to its gaseous phase and becomes invisible to the naked eye by the process of sublimation.

When h20 freezes in the shadow of the shuttle to ice crystals they instantly sublimate to the a gaseous state when they come into contact with direct sunlight.

You can see all 4 phases if you place ice cubes [ solid phase ] in a pan on a stove, the Solid beComes liquid [ liquid phase ]and the liquid becomes a gas in the bottom of the pan when the water boils, [ gaseous phase ] the bubbles coming up from the bottom are the instant phase change from liquid to gas, when the gas bubbles break the surface of the water and the gas comes into contact with the cooler air the gas instantly starts to condense to water droplets i.e. the vapour phase

You can see through the bubbles because h20 in its gaseous phase is invisible to the naked eye.

Gaseous h20 is hot dry and invisible

Vaporous h20 is warm wet and visible

Gaseous h20 is known as a condensing gas in physics because it condenses obviously, condensing gases are also known as optically active gases or radiatively active gases.

Hope this helps all the 3 phase numpties who think vapour i.e. water droplets is actually gas, it isnt or it wouldn’t be called vapour it would be called gas.

Liquid water has to reach its boiling point before it will phase change to its gaseous phase.

Vapor has to boil before the water droplets will phase change to a gaseous state, steam is not gas it is condensing gas i.e. vapour at a lower temperature than boiling point.

hope this helps have a nice day

Thanks!!

Answers

Answer:

a) 3.969

b) 3.487

Explanation:

Given data:

m =  0.27 M

pH = 8.7

a) Calculate PKa of acid HA

pH value = 1/2 ( Pkw + Pka + log C )

    8.7 * 2 = 14 + log C + Pka

        17.4 = 14 + log ( 0.27 ) + Pka

∴Pka = 17.4 - 14.5686 = 3.9686 ≈ 3.969

b) Calculate the pH of solution

pH = pKa + log ( salt / acid )

     = 3.9686 + log ( 0.1 / 0.3 )

     = 3.487

How many moles of a gas would occupy 11.4 L at 273K and 2.00 atm?

Answers

Answer:

1.02mol

Explanation:

Using the general gas equation below;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question,

P = 2.0 atm

V = 11.4L

T = 273K

n = ?

Using PV = nRT

n = PV/RT

n = 2 × 11.4/ 0.0821 × 273

n = 22.8/22.41

n = 1.017

n = 1.02mol

When filling a weather balloon with gas you have to consider that the gas will expand greatly as it rises and the pressure decreases. Let's say you put about 10.0 moles of He gas into a balloon that can inflate to hold 5000.0L. Currently, the balloon is not full because of the high pressure on the ground. What is the pressure when the balloon rises to a point where the temperature is -10.0°C and the balloon has completely filled with the gas.

Answers

Answer:

0.0432 atm

Explanation:

Step 1: Given data for when the balloon is full

Moles of Helium (n): 10.0 molVolume of the balloon (V): 5000.0 LTemperature (T): -10.0 °CIdeal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = -10.0°C + 273.15 = 263.2 K

Step 3: Calculate the pressure of He in the balloon

We will use the ideal gas equation.

P × V = n × R × T

P = n × R × T/V

P = 10.0 mol × (0.0821 atm.L/mol.K) × 263.2 K/5000.0 L = 0.0432 atm

How could a scientist use a sedimentary rock to provide evidence that the right k cycle is a valid scientific model

Answers

Answer:

By closely observing the sedimentary rock and the presence of organic materials and mineral grains in sedimentary rocks

Explanation:

The rock cycle explains how the three types of rock are formed over time from each other.

To use a sedimentary rock to prove that the rock cycle is a valid scientific model is by, closely observing the sedimentary rock. when the sedimentary rock is closed observed the principle of superposition will be seen ( i.e. younger segments deposited on top ), the presence of organic materials and mineral grains that can be found in Igneous or Metamorphic rocks can also be seen and this shows that Sedimentary rocks pass through the rock cycle. hence this proves that the rock cycle is a valid scientific model overtime

The pH scale runs from 0 to 14, with each number assigned a different color. At the bottom of the scale sits red, which represents the most acidic, and a dark blue at its opposite end represents 14 and alkalinity. In the middle zone, the pH scale becomes neutral

The pH of the solution could be 10. The basic solution has a pH value of more than 7.

What is pH?pH is a measure of acidity and basicity of aqueous solution.The range of pH goes from 0 - 14, with 7 being neutral.pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.pH is the measure of the relative amount of free hydrogen and hydroxyl ions in aqueous or other solutions.

Litmus paper helps us qualitatively determine a substance as an acid or base. For any substance to be a base, blue litmus must remain blue.
