Answer:

In 70s we were not much familiar with coca cola. Pepsi were sold in liter and milk is traditionally sold locally sold in gallon.

Explanation:

Sarah Brew said that unlike to the global brand like coca cola, Pepsi are sold at global level but milk is sold at local level follow the local custom measurement. If we look back in history, the milkman sold milk door to door in the form of quartz and the gallons. Same things consumers expected from seller.

These are two ways that play a role in grocery shopping. That's why the congress make a product list in form of liter and metric and traditional inches , gallons, pounds, milk etc.

2. Explain Why would it be difficult to find the volume of a rock using a ruler?

dedylja [7]

Answer:

Most of these rocks are not made up of common geometric shapes

Explanation:

Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's volume using a ruler

A student is asked to standardize a solution of potassium hydroxide. He weighs out 1.08 g potassium hydrogen phthalate (KHC8H4O4

natka813 [3]

Answer:

A. 0.143 M

B. 0.0523 M

Explanation:

Let's consider the neutralization reaction between potassium hydroxide and potassium hydrogen phthalate (KHP).

KOH + KHC₈H₄O₄ → H₂O + K₂C₈H₄O₄

The molar mass of KHP is 204.22 g/mol. The moles corresponding to 1.08 g are:

1.08 g × (1 mol/204.22 g) = 5.28 × 10⁻³ mol

The molar ratio of KOH to KHC₈H₄O₄ is 1:1. The reacting moles of KOH are 5.28 × 10⁻³ moles.

5.28 × 10⁻³ moles of KOH occupy a volume of 36.8 mL. The molarity of the KOH solution is:

M = 5.28 × 10⁻³ mol / 0.0368 L = 0.143 M

Let's consider the neutralization of potassium hydroxide and perchloric acid.

KOH + HClO₄ → KClO₄ + H₂O

When the molar ratio of acid (A) to base (B) is 1:1, we can use the following expression.

$M_{A} \times V_{A} = M_{B} \times V_{B}\\M_{A} = \frac{M_{B} \times V_{B}}{V_{A}} \\M_{A} = \frac{0.143 M \times 10.1mL}{27.6mL}\\M_{A} =0.0523 M$

An atom has a nucleus that has mass and volume. How does the mass of the nucleus compare to the mass of the atom? How does the v

makvit [3.9K]

Answer:

The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.

The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.

The reaction below shows how silver chloride can be synthesized.

Vesna [10]

$AgNO_{3} _{(aq)} + NaCl_{(aq)} ----\ \textgreater \ NaNO_{3} _{(aq)} + AgCl _{(aq)}$
mole ration of $AgCl _{(aq)} : AgNO_{3} _{(aq)}$ = 1 : 1

∴ if moles of $AgNO_{3} _{(aq)}$ = 15.0 mol
then " " $AgCl _{(aq)}$ = 15.0 mol

∴ the Option 2 is the answer.
