Many tall trees grow in a forest. Only a few small plants grow underneath the trees. Why is this so?

Answers

Answer 1

Answer:

Because as more and more trees are tall, they end up blocking the sun to the smaller vegetation and so many plants end up dying or they evolve to grow taller and taller as a way to stay alive.

Answer:

The answer is high entropy.

Explanation:

In this project, you will develop a model of a chemical reaction that either releases energy or absorbs energy. Whether a reaction releases or absorbs energy depends on the overall difference in the bond energies of the reactants and products. Your model should show the relationships between the parts of the system. These parts are the molecules and atoms that take part in the reaction. The model should also distinguish the reaction system from other systems.

Answers

Answer:

B. aq if the reaction is inorganic (double or single displacement), neutralization, etc.

Explanation:

Hello there!

In this case, unfortunately we are not given the undergoing chemical reaction; however, in the most of the double displacement, neutralization, precipitation and in general, inorganic reactions, the hydrochloric acid must be B. aq as it must be dissolved in water as the reaction media. On the other hand, in some organic reactions, it can be either aqueous or gaseous, the latter, specially as a product. For that reason, you will need to make sure whether your reaction is organic or inorganic to correctly figure out the phase label.

Answers

Answer: The missing product in the acid base reaction is NaCl.

Explanation:

Neutralization or acid base reaction is a chemical reaction in which acid and base combine to form salt and water. Acids donate [tex]H^+[/tex] ions and bases donate [tex]OH^-[/tex] ions  in water which combine to form water molecules.

The balanced chemical reaction for the given reaction is ;

[tex]HCl+NaOH\rightarrow NaCl+H_2O[/tex]

Thus the missing product is NaCl.

The missing product in the acid-base reaction is NaCl.

The balanced chemical reaction for the given reaction is ;

[tex]HCl +NaOH[/tex] → [tex]NaCl +H_20[/tex]

What is an acid-base reaction?

When acid and base react with each other they form salt and water. Water and salt both are neutral which means, whenever acid and base react together, they are neutralized by each other.

Neutralization or acid base reaction is a chemical reaction in which acid and base combine to form salt and water.

Acids donate  [tex]H^{+}[/tex] ions and bases donate  [tex]0H^{-}[/tex] ions in water which combine to form water molecules.

Since acid and base neutralize each other's effect,it is called neutralization reaction.

For Example: When Sodium Hydroxide ( NaOH) , a base, reacts with Hydrochloric acid (HCl) , it forms the salt, Sodium Chloride (NaCl) and Water.

The balanced chemical reaction for the given reaction is ;

[tex]HCl +NaOH[/tex] → [tex]NaCl +H_20[/tex]

Thus the missing product in the acid-base reaction is NaCl.

3ppt is the relative error of the method

Explanation:

The relative error is a measurement used to determine the accuracy of your experiment, the equation to find the value in parts per thousand is:

Error = |True Value - Observed Value| / True Value * 1000

Where True value is 23.24%

And Observed value is 23.17%

Answers

Answer:

[tex]0.824\ \text{M}[/tex]

[tex]5.62\ \text{L}[/tex]

[tex]20.89\ \text{mol}[/tex]

Explanation:

Molar mass of NaCl = 58.44 g/mol

Mass of NaCl = 195 g

Volume of solution = 4.05 L

Molarity of solution is

[tex]\dfrac{195}{4.05}\times \dfrac{1}{58.44}=0.824\ \text{M}[/tex]

The molarity of the solution is [tex]0.824\ \text{M}[/tex]

Moles of NaCl = 4.63 mol

Volume is given by

[tex]\dfrac{4.63}{0.824}=5.62\ \text{L}[/tex]

The volume of the solution that contains the required amount NaCl is [tex]5.62\ \text{L}[/tex]

Volume of solution = [tex]25.35\ \text{L}[/tex]

Moles of solution is given by

[tex]0.824\times 25.35=20.89\ \text{mol}[/tex]

The number of moles of NaCl is [tex]20.89\ \text{mol}[/tex].

If 4.50 moles of C2H6 undergoes combustion, how many moles of oxygen would it combust with?

Answers

Answer:

First balance the equation

C2H6 + 7/2O2 2CO2 +3H2O

for one mole of C2H6 there are 7/2 mole of O2 required. so for4.50 moles you require 4.50 x 7/2 = 15.75 moles of O2.

What volume (in mL) of 0.3900 M HCl is required to neutralize 50.00 mL of 0.8000 M NaOH?

Answers

Answer:

102.6 mL

Explanation:

The reaction that takes place is:

NaOH + HCl → NaCl + H₂O

First we calculate how many NaOH moles are there in 50.00 mL of a 0.8000 M solution:

0.8000 M * 50.00 mL = 40 mmol NaOH

Then we convert NaOH moles into HCl moles:

40 mmol NaOH * [tex]\frac{1mmolHCl}{1mmolNaOH}[/tex] = 40 mmol HCl

Finally we calculate the volume of a 0.3900 M solution would contain 40 milimoles:

40 mmol / 0.3900 M = 102.6 mL

Convert 2.178×1010 g to each of the following units.

Answers

Answer:

2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.

Explanation:

The units are kg, μg, mg and metric tons (1metric ton = 1000kg)

To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:

kg:

2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg

mg:

2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg

μg:

2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg

metric tons:

2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons

In many cases, a negatively charged compound (ex Cl-) will interact with a positively charged metal (ex Fe2 ). Usually we would consider this type of interaction to be ionic, but in the case of metals we do not. What type of bond is being formed when a ligand interacts with a metal and how could you know that the bond you are forming is that type of bond

Answers

Answer:

See Explanation

Explanation:

An ionic bond occurs due to electrostatic attraction between a positively charged ion and a negatively charged ion.

A metal and a ligand are bound by a coordinate covalent bond or a dative bond. This bond occurs due to donation of electron pairs from ligands to available orbitals on metals.

The formation of coordinate bonds is evident when neutral molecules or negative ions with non bonding electrons donate same to empty metal orbitals. This is sometimes shown by an arrow pointing from the ligands to the metal center.

For instance; tetraammine copper II ion is formed when four ammonia molecules donate a lone pair each to available vacant orbitals of the copper metal center to form [Cu(NH3)4]^2+.

What is the Kc for the following reaction at equilibrium at 800∘C if [CO2]= 0.030 M ? CaCO3(s)⇌CaO(s)+CO2(g)

Answers

Answer:

0.030

Explanation:

Step 1: Write the balanced reaction at equilibrium

CaCO₃(s) ⇌ CaO(s) + CO₂(g)

Step 2: Calculate the concentration equilibrium constant

The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It doesn't include solids or pure liquids.

Kc = [CO₂] = 0.030

Ice at 0.0 degrees Celsius is combined with 50.0g of water at 75.0 degrees Celsius. Calculate the grams of ice present initially if the entire mixture comes to a final temperature of 25.00 degrees Celsius after the ice melts. Specific heat of water is 4.18 J/g degrees Celsius. SHOW WORK!

Answers

Answer:

m-Ice = 23.85g

Explanation:

The heat absorbed for the cold water (Heat of the increase of water + Heat of ice melting) is equal to the heat released for the water at 75°C. The equation is:

m-Ice-*C*ΔT + Hf*-m-Ice = m-water*C*ΔT

Where m-Ice- is our incognite

C is specific heat of water = 4.18J/g°C

ΔT is change in temperature = 25.0°C - 0.0°C = 25.0°C

Hf is enthalpy of fusion of water = 333.6J/g

m-water = 50.0g

ΔT is change in temperature = 75.0°C - 25.0°C = 50.0°C

m-Ice-*4.18J/g°C*25°C + 333.6J/g*-m-Ice = 50.0g*4.18J/g°C*50.0°C

104.5 m-Ice- + 333.6 m-Ice- = 10450

438.1 m-Ice = 10450

m-Ice = 23.85g
