Without the process of transpiration, what might happen to a plant? A.
It might turn orange.
B.
It would grow more slowly.
C.
It would have fewer leaves.
D.
It might burst.
Transpiration is the process of release of water from the plants. In the absence of transpiration, the plant bursts. Thus, option D is correct.
How the process of transpiration takes place?The transpiration process is the release of water from the plants through stomata. The pressure of water allows the movement of the stomatal guard cell, and the stomata opens.
The opening of stomata releases the water inside the plants, and release of pressure results in the relaxation of stomata, thereby closing the stomata.
The absence of transpiration in plants results in the accumulation of water inside the body. The access water in the body exerts the force to the plant body, and it may burst.
Therefore, in the condition of loss of transpiration by the plants, the plant may burst out. Thus, option D is correct.

Chemical and physical properties are used to help identify substances. A substance's chemical properties identify whether or not that substance reacts with another substance. What chemical property is present in substances that react slowly to oxygen?
Chemical and physical properties are used to help identify substances. A substance's chemical properties identify whether or not that substance reacts with another substance or it can be said that a chemical property of a substance will helps in deciding whether the substance will react or not with another substance. To react with oxygen, the substance should have the ability to burn, the more quickly the substance burn, more readily the substance will burn to produce light and heat.
This can also be explained with the formation of rust on a chemical compound, The more readily the compound reacts with oxygen, more readily it undergoes rusting .
For example when iron kept in open air, it undergoes rust as it reacts with oxygen.
How would you best describe the texture of an igneous rock that formed extremely slowly underground
Answer;
Pegmatitic
Explanation;
-The texture of igneous rocks can be analyzed by geologists to understand the manner in which the rock became solid or crystallized from liquid, or how it is a melted rock. A pegmatitic texture is one in which the mineral grains are exceptionally large.
-Igneous rocks may be identified by determining their composition and texture. Once the two characteristics have been identified, the Igneous Rock Identification chart is used to identify the name of the rock.

51.8 g of magnesium sulfate heptahydrate is heated in an oven until all the water is driven off. What is the mass of the anhydrous compound?.
If 51.8 g of is heated until all the water is driven off. The mass of the anhydrous compound is 25.4g.
Given here,
The mass of is 51.8 g
Molar mass of is 246g/mol
Molar mass of is 120.4 g/mol
The mass of
Hence, we can conclude that the mass of the anhydrous compound is 25.4g.

How many atoms of oxygen are in 8.43 g of magnesium sulfate heptahydrate (Epsom salts)?How many atoms of oxygen are in 8.43 g of magnesium sulfate heptahydrate (Epsom salts)?
Answer: The number of oxygen atoms in given amount of magnesium sulfate heptahydrate is
Explanation:
To calculate the number of moles, we use the equation:
Given mass of magnesium sulfate heptahydrate = 8.43 g
Molar mass of magnesium sulfate heptahydrate = 246.47 g/mol
Putting values in above equation, we get:
The chemical formula of magnesium sulfate heptahydrate is
1 mole of magnesium sulfate heptahydrate contains 1 mole of magnesium atoms, 1 mole of sulfur atoms, 11 moles of oxygen atoms and 14 moles of hydrogen atoms
According to mole concept:
1 mole of a compound contains number of particles
So, 0.0342 moles of magnesium sulfate heptahydrate will contain = number of oxygen atoms
Hence, the number of oxygen atoms in given amount of magnesium sulfate heptahydrate is
***50 POINTS*** Which of the following combinations will result in a reaction that is only spontaneous at low temperatures?
A) positive enthalpy change and positive entropy change
B) positive enthalpy change and negative entropy change
C) negative enthalpy change and positive entropy change
D) negative enthalpy change and negative entropy change
I think it's C, or maybe D, please help!
Given the data, the correct statement is negative enthalpy change and negative entropy change (Option D)
Gibbs free energyΔG = ΔH – TΔS
Where
NOTE
Since the reaction is at low temperature, then TΔS must be smaller than ΔH
Thus, ΔH and ΔS must be negative for the reaction to be spontaneous as illustrated below:
ΔG = ΔH – TΔS
ΔG = (-ve) – T(-ve)
ΔG = (-ve) – T(-ve)
ΔG = –ve

What is the number of protons in the isotope 14C
Which of these statements does not refer to radiation A. some of this energy is is reflected off earths atmosphere
B.warm air rises and takes heat with it eventually it cools and sinks
C.sunlight travels through space without aid of fluids or solids
D.land and ocean absorb and re-emit heat from the sun
Please help quick
The answer is: B.warm air rises and takes heat with it eventually it cools and sinks.
Solar radiation is the source of electric energy.
The thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter.
Heat spontaneously flows from a hotter to a colder body.
The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.
Radiative zone is around the inner core and in this area energy is transported by radiation.
Answer: B.warm air rises and takes heat with it eventually it cools and sinks
Explanation: There are three modes of heat transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases and thus it moves upwards.
3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Warm air rises and takes heat with it eventually it cools and sinks is an example of convection and not radiation.
