35. 124.31 g of silver nitrate reacts with 52.89 g of sodium chloride.
g
a. What is the mass of the products?

Answers

Answer:  Thus mass of products is 177.2 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

[tex]AgNO_3+NaCl\rightarrow NaNO_3+AgCl[/tex]

mass of silver nitrate [tex](AgNO_3)[/tex] = 124.31 g

mass of sodium chloride [tex](NaCl)[/tex] = 52.89 g

mass of reactants = mass of silver nitrate [tex](AgNO_3)[/tex] +

mass of sodium chloride  [tex](NaCl)[/tex] = 124.31 g + 52.89 g = 177.2 g

Thus mass of products = mass of reactants = 177.2 g

Write a net ionic equation for the neutralization reaction of acid with a hydroxide base. (Include phase symbols)

Answers

Answer:

salt + water. It is called the ionic equation for neutralisation. the acid to form a salt solution.

Explanation:

So what you end up with is you always end up H+ plus OH- yields H2O, because HCl, and NaOH, since they're strong, they fully dissociate. So the Na+, and the Cl - are spectator ions. So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.

what is the percent of just the oreo(out of 100%) from the total mass of these 3 cookies combined

Answers

Answer:

Percent mass of oreo = 35.11%

Explanation:

Given:

Mass of oreo =  17.1

Mass of 1st cookie = 16.2

Mass of 3rd cookie = 15.4

Find:

Percent mass of oreo

Computation:

Total mass = Mass of oreo + Mass of 1st cookie + Mass of 3rd cookie

Total mass = 17.1 + 16.2 + 15.4

Total mass = 48.7

Percent mass of oreo = [Mass of oreo/Total mass]100

Percent mass of oreo = [17.1 / 48.7]100

Percent mass of oreo = 35.11%

4 Al + 3 O2 -> 2 Al2O3 How much aluminum would be needed to completely react with 45 grams of Oz?

Answers

Answer:

50.6g Al would be needed

Explanation:

Based on the reaction:

4Al + 3O₂ → 2Al₂O₃

4 moles of aluminium react with 3 moles of oxygen to produce 2 moles of Al₂O₃

To solve this question we need to find the moles of 45g of O₂. Then using the chemical equation find the moles of Al and its mass:

Moles O₂ -Molar mass: 32g/mol-:

45g O₂ * (1mol / 32g) = 1.41 moles O₂

Moles Al:

1.41 moles O₂ * (4mol Al / 3mol O₂) = 1.875 moles Al

Mass Al -Molar mass: 26.98g/mol-:

1.875 moles Al * (26.98g / mol) =

50.6g Al would be needed

The amount of aluminum that would be required to completely react with 45 grams of O2 would be 50.59 grams.

From the balanced equation of the reaction:

[tex]4 Al + 3 O_2 ---> 2 Al_2O_3[/tex]

The mole ratio of Al to O2 is 4:3.

Mole of 45 grams of O2 = mass/molar mass

                                     = 45/32

                                           = 1.4063 moles

Equivalent mole of Al: 4 x 1.4063/3

                                    = 1.875 moles

mass of Al = mole x molar mass

                 = 1.875 x 26.98

                  = 50.59 grams

explain why it is more difficult to produce drinking water from waste water than from water in lakes

Answers

Answer:

Drinking water can be produced from waste water and from lakes but the difference is in the difficulty of producing water which we can consume.

Drinking water should be clean and toxic free so that if does not affect the human body. Waste water carry more toxic matter in comparison to lake water that's why, producing drinking water from waste water takes more time, expensive and difficult.

So, producing drinking water from waste water is more difficult as it require the removal of more toxic matter than water in lakes.

How
many moles of hydrogen gas will form if 0.35 moles of Na reacts with an
excess of water?

Answers

Answer:

0.8 moles

Explanation:

2H2+O2 —›2H2O

Since , from given balanced chemical Equation.

2moles of H2 produce 2 moles of Water

So,

2moles H2= 2moles H2O

1moles H2= 1 mole of H2O

For 0.8 mole of H2O, multiply both sides by 0.8

0.8 H2=0.8 H2O

0.8 mole of H2= 0.8 mole H2O

So answer is 0.8 moles

According to law of conservation of mass the mass in isolated system can neither be created nor destroyed by chemical reaction and physical transformation but it transfer from one form to another.

When wood burn the mass of soot, gases and ashes is equal to the original mass of charcoal and the oxygen when it first created is one of the best example of law of conservation of mass.
