The equality of both units (i.e. mL and ounces) implies they measure the same quantity, and they can be converted between one another.
Given that:
[tex]1 fl\ oz = 29.7mL[/tex]
The measurement in part A is not given. So, I will use an assumed value to provide an explanation.
Assume that the amount of water measured using the measuring cup in part A is 10mL
The equivalent number of ounces (x) is calculated as follows:
[tex]1 fl\ oz = 29.7mL[/tex]
[tex]x = 10mL[/tex]
Cross multiply
[tex]x \times 29.7mL = 1fl\ oz \times 10mL[/tex]
Cancel out common units
[tex]x \times 29.7 = 1fl\ oz \times 10[/tex]
[tex]x \times 29.7 = 10fl\ oz[/tex]
Divide both sides by 29.7
[tex]x = \frac{10}{29.7}fl\ oz[/tex]
[tex]x = 0.3367 fl\ oz[/tex]
Approximate to the nearest half
[tex]x = 0.5 fl\ oz[/tex]
This means that the equivalent amount of water is 0.5 ounces
What if the measurement is 55mL.
We apply the same steps, as follows:
[tex]1 fl\ oz = 29.7mL[/tex]
[tex]x = 55mL[/tex]
Cross multiply
[tex]x \times 29.7mL = 1fl\ oz \times 55mL[/tex]
Cancel out common terms
[tex]x \times 29.7 = 1fl\ oz \times 55[/tex]
[tex]x \times 29.7 = 55fl\ oz[/tex]
Divide both sides by 29.7
[tex]x= \frac{55}{29.7 }fl\ oz[/tex]
[tex]x= 1.85185 fl\ oz[/tex]
Approximate to the nearest half
[tex]x = 2fl\ oz[/tex]
This means that the equivalent amount of water is 2 ounces

1. Why Isn't Hess's law helpful for calculating the heat of reaction Involved in the conversion of diamond to graphite?
Answer:
This law is not applicable or not helpful in the conversion of diamond to graphite because both are just allotropes of carbon along with C60 (Buckminsterfullerene or buckyball), C540, C70, amorphous carbon, and carbon nanotube

What is required for electrons to move from the stable energy level to an excited state?
answer
When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle

he difference between a stable isotope and an unstable isotope of an element is that __________. ANSWER the unstable isotope decays and is always transformed into a stable form of the same element the stable isotope has a nucleus that decays spontaneously and is radioactive the unstable isotope has a nucleus that does not decay spontaneously and is never radioactive the stable isotope has a nucleus that decays spontaneously but is not radioactive the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another elemen
We know that any known element is defined by the number of protons in its nucleus (which is the same as the number of orbiting electrons).
We can define isotopes as the atoms of the same element but that have a different number of neutrons in the nucleus. The correct statement of the difference between stable isotopes and unstable isotopes is:
"The difference between a stable isotope and an unstable isotope of an element is that the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another element"
Particularly we can define two of these, the stable isotopes, that can remain as they are for a lot of time, and the unstable isotopes, that have more neutrons in its nucleus than a stable isotope, and because having those extra neutrons in the nucleus needs energy, eventually the isotope will experience a spontaneous radioactive decay, which "breaks" the nucleus in different ways, and, in some cases, generates different elements in the process.
Then we can conclude that:
"The difference between a stable isotope and an unstable isotope of an element is that the unstable isotope has a nucleus that decays spontaneously, is radioactive, and can be transformed into an atom of another element"

Why will goats protect wildfires
Explanation:
The goats can stretch their necks up to 7 feet, biting branches and low lying leaves. They eat poison oak and can clear rocky cliffs -- something other livestock can't do. And it's easier to control where the goats cut a fire break, unlike controlled burns -- another method of removing wildfire fuel.

C. The Earth is flat. Anybody can see that!
D. Taking Vitamin C prevents the common cold. Linus Pauling, the Nobel laureate who discovered the structure of
Vitamin C, says it does.
E. Humans have a soul. I believe this because it says so in the Bible. The soul is what separates us from animals.
F. The rate of acceleration of all falling objects on Earth is constant. Two spheres of identical diameter and volume are

C: Flat Earthers still exist, but no one has ever fallen off the edge, that I'm aware of
E: I've had a few pets with souls. My cat has it in for me.
D: I met Linus Pauling twice - he was too enthusiastic with his vitamin C and did not critically evaluate the evidence, but he was far more correct than the Flat-Earthers.
A: Lots of good evidence, although it can also depend on the definition of "living," Is a virus "living?"
F: Yep, I've done it myself. Heavier object have more inertia - they are the couch potatoes of physics. They will take their own time to get moving.

what is the concentration of hydrogen ion, H+, present in a water sample if 100. ml of the sample requires 7.2 ml of 2.5 x 10 -3 M NaOH to be neutralized
Answer: 1.8x10^-4 M H+
Explanation: The number of moles of NaOH added to the 100 ml soultion will be equal to the number of moles of H+ present in that solution.
Moles NaOH in 7.2 ml of 2.5x10^-3 M NaOH
(2.5x10^-3 M NaOH) is the same as 2.5x10^-3 moles NaOH/liter
(2.5x10^-3 moles NaOH/liter)*(7.2 ml)*(1 liter/1000ml) = 1.8x10^-4 moles NaOH used to titrate 100 ml of the acid. That means there was 1.8x10^-4 moles of H^+ in 100 ml.
Concentration of H^+ = (1.8x10^-4 moles H)/0.100 l) = 1.8x10^-4 M H+
(pH of 3.74)
An excess of a divalent metal M was dissolved in a limited volume of hydrocloric acid. If 576cm³ of hydrogen was librated at s.t.p , what was the mass of metal that produced this volume of gydrogen?( M = 24, H = 1 , molar volume of gas at s.t.p = 22.4dm³)
Answer:
14.8 g
Explanation:
step 1 You first have to convert the cm^3 to dm^3 by dividing the volume by 1000 then find the number of mols for Hydrogen gas
from there you can use the of moles for hydrogen to find the moles of the metal step 2
then step 3 you multiply the number of by The Mr or Fr giving you your mass
what are the three formula of mole?
