Answer:
The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber
Explanation:
A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.
Answer:
To obtain the grams of fat that the ground round has, knowing that it weighs 1.33 pounds we must pass this value to grams. Since 1 pound equals 453.59 grams, 1.33 pounds equals 603.27 (453.59 x 1.33).
Now, to obtain 29 percent of 603.27, we must make the following calculation: 603.27 / 100 x 29, which gives a total of 174.94 grams.
In this way, your reasoning is correct and it is probably a mistake in the book.
Water with high levels of calcium ions is referred to as hard water. While hard water has health benefits, this type of water has economic implications in the industry and households too. In the industry, hard water can cause a breakdown of equipment such as boilers, over time. In the household, too much soap is used when washing with hard water than soft water. Therefore hard water requires to be softened before industrial use. Economically, this increases the cost of production.
Answer:
6.37.
Explanation:
What is given?
[H (+)] = 4.25 x 10⁻⁷ mol/dm³
Step-by-step solution:
First, let's see the formula to calculate the pH based on the hydrogen ion concentration (H (+)):
![pH=-log\lbrack H^+].](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack%20H%5E%2B%5D.)
*Logarithm must be in base 10!
Our given concentration of hydrogen ion is 4.25 x 10⁻⁷ mol/dm³. Remember that the units of concentration must be in M (mol/L) but in this case, 1 dm³ equals 1 L, so based on this, we have that:
So, we can replace this value in the formula of pH:
![pH=-log\lbrack4.25\cdot10^{-7}]\approx6.37.](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack4.25%5Ccdot10%5E%7B-7%7D%5D%5Capprox6.37.)
The pH of milk would be 6.37 which means that is slightly acid (weak acid).
