Continued deforestation will most likely lead to _______.a.
a decrease in the number of endangered species
b.
an increase in the number of endangered species
c.
an increase in the number of oil and chemical spills
d.
a decrease in glacial melting

Answers

Answer 1
Answer: In the question "Continued deforestation will most likely lead to _______." the correct answer is "an increase in the number of endangered species" (option b).
Deforestation is the clearing of forest areas for use for non forest activities. Because there are a lot of animals that use forests as their home, clearing of the forest will make them homeless and will subject them to conditions that may lead to their death and possible extinction.

The oxygen side of a water molecule is _____.neutral
slightly negative
slightly positive

Answers

Answer is "slightlynegative".

Explanation

In water molecule, there are 3 atoms which belonged to 2 elements. They are 2 Hatoms and 1 O atom. Oxygen atom is more electronegative than H atom. Hence,Oxygen atom in the water molecule gets a slightly negative chargeon it.

What is electronegativity?

Electronegativity is a value that tells us how an atom can attract electronstowards itself.
It helps us to tell the nature of molecule (as polar or non-polar) and thenature of the bond between atoms (as ionic or covalent). 
If the electronegativity is high, then the attraction to the electrons is highunless the attraction to the electrons is low. 
If the attraction towards electrons is high, then that atom gains a negativecharge on it. 

Answer:

The correct answer is: B

Explanation:

slightly negative

What is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid?

Answers

the theoretical  yield   of  hydrogen gas is  10 g

   calculation

Step 1: write the equation for reaction

Zn + 2 HCl →  zncl₂  + H₂

Step 2: use the mole ratio to find the moles of H₂

from equation above Zn : H₂  is 1: 1 therefore the  moles of H₂ = 5.00 moles

Step 3: find the theoretical yield(mass) for H₂

mass = moles  × molar mass

from periodic table the molar mass of H₂= 1×2  = 2 g/mol

mass  =  5  moles  × 2 g/mol  = 10 grams

Answer:

B.  10.1 g

An ionic bond would most likely form between atoms of which of these pairs?A. oxygen and oxygen
B. magnesium and oxygen
C. magnesium and magnesium

Answers

Magnesium and oxygen would form an ionic bond because magnesium is a metal and oxygen is a nonmetal, and metals and nonmetals usually form ionic bonds.

A particle has 5 protons, 6 neutrons, and 5 electrons. What is its net charge.

Answers

It would have a zero charge because it is a neutral atom. The number of electrons which is a negative charge is equal to the number of protons which is positive, they will cancel each other out hence meaning it will become neutral
