229.25 mL of isopropyl alcohol
425.75 mL of water
Explanation:
Knowing that the solution have a 35.0 % (v/v) isopropyl alcohol in water, we can calculate the volume of each component as following.
volume of isopropyl alcohol = (35/100) × solution volume
volume of isopropyl alcohol = 0.35 × 655 mL = 229.25 mL
Now, knowing the volume of isopropyl alcohol we can determine the volume of water.
volume of the solution = volume of isopropyl alcohol + volume of water
volume of water = volume of the solution - volume of isopropyl alcohol
volume of water = 655 mL - 229.25 mL = 425.75 mL

H is 2
Total is 5
Explanation:
They are asking for the number of atoms in each element.
Answer:
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
Explanation:
please mark me brainliest.
the balanced equation is as follows
2H₂S + 3O₂ --> 2SO₂ + 2H₂O
molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation
molar ratio can be determined by the coefficients of the compounds in the balanced reaction
coefficient is the number in front of the chemical compound
coefficients for the compounds in this reaction are as follows
H₂S - 2
O₂ - 3
SO₂ - 2
H₂O - 2
therefore correct option is
H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2
