Calculate the massa of water produced if 1.00 gran of hydrogen is burned in 10.00 grams of oxygen(work as well pleaseee)

Answers

Answer 1

Answer: The first step to this question is finding the balanced chemical reaction.
H₂+1/2O₂⇒H₂O
Then you need to find the limiting reagent by finding the moles of each reactant then finding how much product each amount of reactants will form. The reactant that produces the least amount of product is the limiting reagent.
moles of H₂:
1g/(1g/mol)=1mol
moles of O₂:
10g/32g/mol=0.3125mol
moles of H₂O formed with amount of H₂:
1molH₂x(1molH₂O/1molH₂O)=1molH₂O
moles of H₂O formed with amount of O₂:
0.3125molO₂x(1molH₂O/0.5molO₂)=0.625molH₂O
Since less water is produced with the amount of oxygen given, oxygen is the limiting reagent and the moles of water formed from the oxygen is the moles of H₂O we will use to find the amount of H₂O produced.
0.625molH₂Ox18g/mol=11.25g H₂O

In a titration of 0.5 M HCl and an unknown concentration NaOH, 25.0 ml of NaOH was required to completely neutralize 25.0 ml of HCl. What is the concentration of the NaOH?

Answers

When an acid is neutralized by a base, that means moles of H+ = moles of OH-

moles of H+ = 0.5 M * 0.025 L HCl = 0.0125 moles H+

moles of OH- should be equal to 0.0125 moles, so
0.0125 moles = (x) * 0.025 L NaOH

x is the concentration of NaOH, which we want to find.

x = 0.5 M

The correct answer is C) 0.5 M.

Dinitrogen trisulfide symbol

Answers

Dinitrogen trisulfide symbol:N2S3

Final answer:

The symbol for the compound dinitrogen trisulfide is N2S3. It is derived from the number of nitrogen and sulfur atoms present in the compound.

Explanation:

The chemical compound dinitrogen trisulfide is composed of two elements: nitrogen (N) and sulfur (S). When we name the compound according to IUPAC nomenclature rules, we consider the number of each type of atom present. Dinitrogen means there are two nitrogen atoms, represented by the subscript 2, and trisulfide implies that there are three sulfur atoms, signified by the subscript 3. Hence, the symbol or chemical formula for dinitrogen trisulfide is N2S3.

What defines the mass number of an isotope? the sum of the neutrons and protons the sum of the neutrons and electrons the number of neutrons the number of protons

Answers

Answer:

The mass number of an isotope is the sum of neutrons and protons.

Explanation:

In any elemental isotope, the only things that will affect molar mass and mass number is the number of protons and neutrons. Electrons are not counted because we usually assume they are equal to the amount of protons and have no weight.

Protons are what gives the element its atomic number and the neutrons determine the type of isotope it is within the element.

For instance:

There can be a regular Carbon - 12

But there are isotopes like Carbon - 13 and Carbon - 14.

*The number of protons stays the same but the number of neutrons are different
