Answers
Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.

If 12.7 grams of hydrogen reacted with an unknown amount of oxygen, how many grams of water would be produced? (Write a balanced equation and show your work under the equation)
Answers
Answer:
2H2 + 1 O2 ------> 2H2O
m = 12.7g m = ?
Get the number of moles for Hydrogen gas (H2) by dividing the mass by the molar mass (1.01g/mol as listed in the periodic table for its atomic mass)
12.7/1.01 = 12.57 mol of H2
Now use the mole to mole ratio of Hydrogen gas (H2) and water (H2O).
From the balanced equation, we can see that 2 mol of H2 gives us 2 mol of H2O. Since both of the ratios are equal (2:2), the moles we have for hydrogen gas is the same as the moles we get for water.
12.57 mol of H2O
Now that we have the amount of mol for H2O produced in this reaction, we can convert it to grams by multiplying the moles by the molar mass.
Molar mass of H2O = (1.01 x 2) + (16) = 18.02g/mol
12.57 x 18.02 = 226.5g (rounded)
Therefore 226.5g of water will be produced in this reaction
According to law of conservation of mass and stoichiometry, 114.3 g of water are produced if 12.7 grams of hydrogen reacted with an unknown amount of oxygen.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
2 H₂ + O₂[tex]\rightarrow[/tex] 2 H₂O,according to this equation,4 g hydrogen reacts with 32 g oxygen to give 36 g water, thus 12.7 g of hydrogen will produce 12.7×36/4=114.3 g water and hence for this amount of water to be formed 12.7 g of hydrogen reacts with 101.6 g of oxygen which is obtained as 114.3-12.7=101.6 g
Thus, 114.3 g of water is produced.

Answers
The types of mixtures are homogeneous and heterogeneous, you can identify these based on their features.
A mixture occurs when two or more materials are mixed or combined. For example, if you combine two or more liquids. Moreover, this can lead to two types of mixtures:
Homogenous mixtures.Heterogeneous mixture.Each of these has defined features that affect the characteristics and properties of a mixture:
Homogenous mixtures:
Once the mixture is done its components cannot be easily identified.The composition is uniform.Some examples include lemonade, smoothy, and concrete.Heterogeneous mixture:
The components can be easily identified and even separated after the mixture.The composition is not uniform.Some examples include salad, pizza and oil mixed with water.Note: This question is incomplete because of this, I answered based on general knowledge.

Answers
Some molecules in a substance have a high kinetic energy hence they are able to convert into vapor. These molecules exert pressure on the liquid surface.
We know that the molecules that compose matter are in constant random motion. The kinetic energy of all the molecules in the liquid are not the same. The molecules at the surface of the liquid posses more kinetic energy than the molecules below.

Gasoline has a density of 0.7197 grams per milliliter. Calculate the mass, in grams, of a sample of gasoline with a volume of 48.5 milliliters.
Answers
Answer:
34.9103 or 34.9 g
Explanation:
Remember Density is a broken heart: m/v.
In this scenario (Let x = # of grams in the sample of gasoline),
D = 0.7198 g/mL = x g / 48.5 mL
So,
(0.7198 g/mL) * (48.5 mL) = x g
x g = 34.9103 = 34.9 g (Accounting for Significant Figures)

How many moles of AgNO3 must react to form 0. 854 mol Ag? mol AgNO3.
Answers
The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.
The balanced chemical equation for the dissolution of silver nitrate has been:
[tex]\rm AgNO_3\;\rightarrow\;Ag^+\;+\;NO_3^-[/tex]
The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.
In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.
From, the balanced equation,
[tex]\rm 1\;mol\;AgNO_3=1\;mol\;Ag[/tex]
The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:
[tex]\rm 1\;mol\;Ag^+=1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;\times\;1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;mol\;AgNO_3[/tex]
The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.
