Deforestation often leads to an increase in the number of endangered species of plants and or animals.
What is deforestation?Deforestation refers to the conversion of forests to non-forest uses. In other words, it is the removal of forest layers for non-forest reasons.
Since forests represent a hotspot for plant and animal biodiversity, their removal automatically means a decrease in biodiversity.
Endangered species are species of plants and animals that are under the threat of going extinct either due to natural or anthropological effects.
Thus, deforestation often leads to an increase in the number of endangered species.

How much of each reactant(zinc and hydrochloric acid) is needed to produce 150 grams of hydrogen gas
Explanation:
150 grams is .15 liters
1 mole of gas at STP occupies 22.414 liters
.15 liter of hydrogen represents .15/22.414 =
0.0066922 moles of H2
equation is
Zn + 2HCl → ZnCl2 + H2
1 mole of Zn will make 1 mole of H2
0.0066922 moles of Zn will make 0.0066922 moles of H2
To convert this molar quantity of zinc into grams we simply multiply by the atomic mass of zinc, which is
65.38 g/mol;-
Mass of Zn required = 0.0066922 moles * 65.38 g/mol = 0.4375390381 grams

A canister has a fixed volume. If the pressure of the cannister is 1.5 atm at 25 Celsius, what is the new pressure if the temperature rises to 75 degrees Celsius?
a) 4.5 atm
b) 1.6 atm
c) 1.3 atm
d) 1.8 atm
Answer:
d) 1.8 atm
Explanation:
According to Boyle's Law,
P₁/T₁ = P₂/T₂Here, we are given :
P₁ = 1.5 atmT₁ = 25°C = 298 KT₂ = 75°C = 348 KSolving
P₂ = P₁T₂/T₁P₂ = 1.5 x 348 / 298P₂ = 522/298P₂ = 1.8 atm (approximately)fossil fuel in a sentence

Based on your research, which source of energy do you think best meets the needs of society? Defend your answer in 50 to 100 words.
Energy is the fundamental need for lives. Fossil fuel is the energy source that is most needed in society. It is now replaced with solar energy as fossil fuels are nonrenewable resources.
What is the non-renewable and renewable source?Nonrenewable resources are energy sources that are finite in amount and get depleted after some time as it takes millions of years to produce these resources. Fossil fuels though are needed but are nonrenewable and cause pollution.
Solar energy is a renewable source that is present in abundant and infinite quantity and does not get depleted fast after they are used excessively. They are also environmentally friendly and do not produces much pollution.
Therefore, fossil fuel and solar energy are the most demanded sources.

Sulfuric acid can dissociate into _______ ions and hydrogen ions which lowers the ph causing acidic environments that are very harmful to many ecosystems.
Sulfuric acid can dissociate into hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−).
Does sulfuric acid dissociate or ionize?
Sulfuric acid is a very strong acid which ionizes into hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−) while on the other hand, in dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42−).
So we can conclude that Sulfuric acid can dissociate into hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−).

Kiera and Grace are sisters. They both have blue eyes. Kiera is extremely short for her age and Grace is exceptionally tall for her age. Develop a hypothesis as to why the sisters have different statures. Justify your hypothesis in two or more complete sentences.
The hypothesis as to why the sisters have different statures occurs because from genetics we know that it is linked to the alleles so one sister is shorter than the other one was they had different alleles.
What is the genetic similarity between siblings?On average, siblings share about 50% of their DNA with each other, but some siblings share even more and some less. So while we all have approximately 50% DNA from each parent, the segments we end up getting are completely random.
Hereditary character or gene that is manifested by the absence of the opposite gene, called dominant, in this case, Kiera is extremely short for her age.

What is the OH- in a solution with a pOH of 7.68?
Answer:
Explanation:
Answer: 1.380 × 10^-8 M
The pH is the measure of alkalinity or acidity of a substance.
It is the negative logarithm of H+ ions concentration [H+].
pH = -log[H+]
pOH on the other hand is negative logarith of OH- concentration [OH-].
pOH = -log[OH-]
In this case;
pOH = 7.86
We can calculate the [OH-]
pOH = -log[OH-]
But, pOH = 7.86
pOH = -log[OH-]
-log[OH-] = 7.86
[OH-] = Antilog -7.86
= 1.380 × 10^-8 M
Therefore, [OH-] is 1.380 × 10^-8 M
what are the molecular structure,structural formula and strength of intermolecular forces for the substances methylated spirits,Acetone,water,glycerine and oil?
Answer:
Glycerine, water and methylated spirits have hydrogen bonds between the molecules. However, in water and Glycerine these intermolecular forces are very strong while in the methylated spirits they are slightly weaker. This leads to the higher boiling point for water and Glycerine.
Explanation:
In chemistry a molecular formula indicates every single atom and its numbers in a chemical compound. Hence the molecular formula C3H8O3 simply says that there are three carbon (C) atoms, eight hydrogen (H) atoms and three oxygen (O) atoms in this compound.
Calculate molecular mass of Ca(OH)2
Answer:
The molar mass of calcium hydroxide,
Ca(OH)2, is 74.092 g/mol.
Explanation:
The molar mass of a compound is determined by multiplying the subscript of each element in the formula by its molar mass (atomic weight on the periodic table) in g/mol, and adding the results.
The formula for calcium hydroxide is: Ca(OH)2
Molar Mass Ca(OH)2:
(1×40.078g/mol Ca)+(2×15.999g/mol O)+(2×1.008g/mol H)
=74.092 g/mol Ca(OH)2
Answer:
74.093 g/mol
Explanation:
Add the mass of Ca (found on the periodic table), the mass of 2 oxygens and 2 hydrogens together.
40.078+2(15.999)+2(1.00784)=74.093
