What is the formula equation for the reaction between sulfuric acid and dissolved sodium hydroxide if all products and reactants are in the aqueous or liquid phase?

Answers

Answer 1

Answer: The formula equation for the reaction between sulfuric acid and dissolved sodium hydroxide will be the same even if all products and reactants are in the aqueous or in the liquid phase. It is as follows:

H2SO4 + 2NaOH = Na2SO4 + 2H2O

Answer 2

Answer: C) H2SO4 + 2NaOH = Na2SO4 + 2H2O

A spherical ball of lead has a diameter of 2.5 cm . What is the mass of the sphere if lead has a density of 11.34 g/cm3? (The volume of a sphere is (43)πr3 where r is the radius.)

Answers

Answer : The mass of sphere is 92.727 grams.

Explanation :

To calculate the volume of sphere, we use the formula:

$V=(4)/(3)\pi r^3$ .....(1)

where,

r = radius of sphere

Given :

Diameter of sphere = 2.5 cm

Radius of sphere = $(Diameter)/(2)=(2.5cm)/(2)=1.25cm$

Now put all the given values in the above formula (1), we get:

$V=(4)/(3)* 3.14* (1.25cm)^3$

$V=8.177cm^3$

To calculate mass of a substance, we use the equation:

$Density=(Mass)/(Volume)$ .....(2)

Putting values in above equation (2), we get:

$11.34g/cm^3=(Mass)/(8.177cm^3)$

$Mass=92.727g$

Hence, the mass of sphere is 92.727 grams.

mass = volume x density

volume = πr²
since Diameter = 2.5 cm
then radius = 1.25cm

∴ volume = π x (1.25cm)³
≈ 6.1359 cm³

Thus mass = 6.1359 cm³ x 11.34 g / cm³
= 69.58 g

propose a mathematical equation to calculate tje charge on an ion from the number of protons and electrons in an ion.

Answers

If the ion is a cation, it has a positive charge because it LOST electrons. If its an anion, then it has a negative electron because it GAINED electrons.

Why are hydrophobic molecules such as fats and oils unable to dissolve in watery solutions?

Answers

Hydrophobic mplecules are unable to fissolve in watery solution becuse they dislike water.

Hydro= water
-phobic= fear

Hydrophobic= fear of water, or disliking water
*Think of it like this:
when you mix oil and water, do they mix, or does oil float at the top?

If your reply is "oil float to the top", then you're right. Oil and water DOES NOT mix together. Hope that help!
