Tropism is the movement that plants make in response to a stimulus from the outside, hydrotropism and gravitropism work together in the roots adaptation.
What are hydrotropism and gravitropism?Hydrotropism is the response of the plant to an aquatic stimulus, it is usually reflected in the growth of the roots oriented by the availability of water.
On the other hand, the growth towards the ground of the roots is determined by another tropism: gravitropism, a response to the force of gravity, together with hydrotropism, plants take advantage of water throughout their development and adaptation.
Therefore, we can conclude that depending on the nature of the stimulus, tropisms are classified in different ways, hydrotropism and gravitropism work together in the plant's adaptation.

Besides color, what other factors do designers consider when coming up with winning color combos?
Answer:
Consider your personal preferences first because the colors you use in your home need to reflect those preferences as well as fit in with your lifestyle.
Light has an influence over the colors that can make them look stunning as well as dull. Different types of light sources such as incandescent, fluorescent, halogen, or LED will affect the way a color appears.
The orientation of the room such as the direction it faces or how much natural or artificial light is available can also affect how colors will appear in the room. So, consider the room specifications as well.
Consider fixed as well as furnished elements and accessories as they too have color. Take them into consideration to ensure that camouflaging or clashing doesn’t happen.
Consider the texture of walls whether they are smooth, rough, or in between. The texture will change the appearance of the color. Smooth walls will appear lighter while rough walls will appear darker.
Consider the kind of mood you want to set in a particular room. Different colors as well as their hues and combinations emote different feelings.
Consider the finishing if the paint whether to use gloss, semi-gloss, or satin to name a few. The finish of the t will have a lot to do with the final look of your color.

In an experiment, 200.00 grams of Al2O3 was decomposed producing 77.18 grams of Al. Calculate the percent yield for this experiment?
Answer:
Explanation:
Molecular weight of Al: 27
Molecular weight of O: 16
Percentage composition of Al by weight in Al2O3
= (27*2) / (27*2 + 16*3)
= 0.5294
In 200 grams of Al2O3, there are
= 200*0.5294
= 105.88 grams of Al
77.18 grams of Al was produced in the experiment.
Percent yield for the experiment
= product mass / reactant mass * 100%
= 77.18 / 105.88 * 100%
= 72.89%

How many moles of Sb2O3 will be formed when you have 20.0 moles of O2?
The number of mole of S₂O₃ produced from the reaction is 13.33 moles
Balanced equation
4Sb + 3O₂ —> 2S₂O₃
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles of S₂O₃
How to determine the mole of S₂O₃ producedFrom the balanced equation above,
3 moles of O₂ reacted to produce 2 moles of S₂O₃.
Therefore,
20 moles of O₂ will react to to produce = (20 × 2) / 3 = 13.33 moles of S₂O₃.
Thus, 13.33 moles of S₂O₃ were obtained from the reaction.

mention 10 products made from crude oil
Answer:
"After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt.
A U.S 42-gallon barrel of crude oil yields about 45 gallons of petroleum products in U.S. refineries because of refinery processing gain. This increase in volume is similar to what happens to popcorn when it is popped."
"What are petroleum products, and what is petroleum used for?
Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use. Of the approximately 7.21 billion barrels of total U.S. petroleum consumption in 2016, 47% was motor gasoline (includes ethanol), 20% was distillate fuel (heating oil and diesel fuel), and 8% was jet fuel."

In a first-order reaction, the initial concentration of A is 0.40 M. What is the concentration of A after 15 seconds if the half-life of the reaction is 3 seconds
Answer:
0.0125M
Explanation:
yess! i love half life reactions!
half life equation: [tex]N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} }[/tex]
so basically, the initial amount is N_o
t_1/2 is the half life
and t is the time
0.40(1/2)^15/3= 0.0125M
The concentration of A after 15 seconds if the half-life of the reaction is 3 seconds is 0.0125M.
What is half life reaction ?The amount of time needed for a reactant to achieve half of its starting concentration or pressure is known as the half-life of a reaction. The half-life for a first-order reaction is concentration-independent and stable over time.
The amount of time it takes for the concentration of a given reactant to reach 50% of its initial concentration is known as the half-life of a chemical reaction (i.e. the time taken for the reactant concentration to reach half of its initial value). It is commonly expressed in seconds and is represented by the sign "t1/2."
The amount of time required for the reactant concentration to drop to half its initial value is known as the half-life of a reaction. A constant that is connected to the rate constant is the half-life of a first-order reaction.
The half life equation is
N(t) = N₀ (1/2)⁽ t / t¹/²⁾
N(t) = quantity of the substance remaining
N₀ = initial quantity of the substance
t = time elapsed
t_{1/2} = half life of the substance
so basically, the initial amount is N₀
t_1/2 is the half life and t is the time
0.40(1/2)^15/3
= 0.0125M
Thus, The concentration of A after 15 seconds if the half-life of the reaction is 3 seconds is 0.0125M.

Explanation:
Because it's where the products and reactants meet together.
The system at dynamic equilibrium is 2.
What is dynamic equilibrium?
Rate of forward reaction is equal to the rate of backward reaction.Dynamic Equilibrium can be described because of the state of a given device wherein the reversible response taking vicinity in it stops converting the ratio of reactants and merchandise, but there may be a motion of materials between the reactants and the products.Many physical and chemical processes are reversible. A reversible system is stated to be in dynamic equilibrium while the ahead and reverse procedures arise on the same price, ensuing in no observable change within the system.
