BASED ON THE INFORMATION BELOW. CALCULATE THE MASS FOR ONE OF THESE ATOMS:MASS OF A SINGLE CARBON ATOM:MASS

Answers

Answer 1

C = 12 g

O = 16 g

H = 1 g

Further explanation

Conservation of mass stated that  

In a closed system, the masses before and after the reaction are the same

we can calculate the mass of each atom in the compound :

O in O₂ :

mass O₂ = 32

mass O = 32 : 2 = 16 g

H in H₂O

mass H₂O = 18

mass 2.H + mass O = 18

mass 2.H + 16 = 18

mass 2.H=2

mass H = 1 g

C in CH₄

mass CH₄ = 16

mass C + mass 4.H = 16

mass C + 4.1=16

mass C = 12 g

or we can use formula :

Mass of a single C :

[tex]\tt =\dfrac{Ar~C}{MW~CO_2}\times mass~CO_2\\\\=\dfrac{12}{44}\times 44=12[/tex]

C. If an electron is added to the outer shell, how will this affect the charge and volume of the atom?
if an electron is added on the outer shell

Answers

Answer:

An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion.

Answer:

when an atom gains an electron, it gains a negative charge . it's volume increases as well due to the increase in repulsion between the electrons

What is the pH after two solutions are mixed: 1. A 0.155 M H2SO4 solution with a volume of 35.0 mL and 2. A 0.225 M solution of KOH with a volume of 35.0 mL. The volumes are additive.

Answers

Answer:

[tex]pH=1.67[/tex]

Explanation:

Hello.

In this case, since the reaction between the sulfuric acid and the potassium hydroxide is:

[tex]2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O[/tex]

We can see a 2:1 mole ratio between them, thus, we compute the moles of acid and base that are present in the solution by using the employed volume and its concentration:

[tex]n_{H_2SO_4}=0.155mol/L*0.0350L=0.005425molH_2SO_4\\\\n_{KOH}=0.225mol/L*0.0350L=0.007875molKOH\\[/tex]

Next, we use the 2:1 mole ratio to compute the consumed moles of acid:

[tex]n_{H_2SO_4}^{consumed}=0.007875molKOH*\frac{1molH_2SO_4}{2molKOH}=0.0039375molH_2SO_4[/tex]

It means that the leftover of sulfuric acid is:

[tex]n_{H_2SO_4}^{leftover}=0.005425-0.0039375=0.001488molH_2SO_4[/tex]

Therefore, since sulfuric acid is a strong acid, the pH is defined in terms of its concentration which is actually equal to the concentration of hydrogen ions in solution, which is computed considering the total additive volume:

[tex][H^+]=[H_2SO_4]=\frac{0.001488mol}{0.070L}=0.02125M[/tex]

So the pH turns out:

[tex]pH=-log(0.02125)\\\\pH=1.67[/tex]

Best regards.

According to the nissani what can be some possible ways to save the forest of third world countries​

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, there are ways to save the forest of third world countries - this includes

1) Creating of forest reserves: Wide areas of land that are still forested can still be preserved and converted to forest reserves which can prevent these areas from being deforested as a result of human activities or industrialization.

2) Government policies: Government can put policies in place to prevent people from embarking on deforestation of certain lands. This is because some parts of the third world countries still rely on wood for cooking and other sources of daily activities.

3) Replanting of deforested areas: Replanting of trees can also help third world countries in saving the forest.
