I believe it would make the most sense to say that the highest mass will have the highest density, and the lowest mass will have the lowest density, if we’re speaking in terms of that the density is affected my its mass.

If the density of an object is affected by its mass, then <u>osmium</u> will have the highest density and <u>hydrogen</u> will have the lowest density

Density = mass/volume or <em>D = m</em>/<em>V </em>

If we hold <em>V</em> constant, we can write <em>D = km</em>. where <em>k</em> = 1/<em>V</em>.

Thus, D ∝ <em>m</em>. As the <em>mass</em> of a fixed volume of a substance <em>increase</em>s, the <em>density increases</em>.

The mass of H₂ in 1 cm³ 0.080 g. The mass of Os in 1 cm³ is 22.6 g.

However, there are substances with even higher densities. For example, the material at the centre of a neutron star is so dense that 1 cm³ of the material has a mass of 10¹² kg!

A glass cup of orange juice is found to have pOH of 11.40. Calculate the concentration of the hydrogen ions in the juice.​
fgiga [73]

Answer: The concentration of hydrogen ion is 2.5 x 10∧-3.

Explanation:

It is well known that; pH + pOH = 14

∴ pH + 11.40 = 14

  pH = 14 -11.40 = 2.60

Remember that,

pH = - Log [ H+ ]

2.60 = - log [H+]

To get the  hydrogen ion concentration, we take the anti-log of 2.60.

[H+] = Antilog 2.60 = 2.5 x 10∧-3.

Bonds payable to whomever holds them are called _____ bonds or unregistered bonds.
Hatshy [7]

Bonds payable to whomever holds them are called bearer bonds or unregistered bonds.

<h3>What is bearer bond ?</h3>

Bonds that have no registered owners are known as bearer bonds. Instead, the bond is owned by whoever "bears" (or has possession of) it. Bearer bonds, sometimes known as coupons, have coupons that bondholders can detach and present to receive interest payments.

<h3>What are interest payments ?</h3>

An interest rate is the amount of interest that is payable each period stated as a percentage of the amount that was lent, deposited, or borrowed. The principal amount, interest rate, frequency of compounding, and duration of the loan, deposit, or borrowing determine the total amount of interest on a sum that was lent or borrowed.

When a person pushes off a wall with 15N of force,how much force does the wall push back
aivan3 [116]
Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.
