what is different about these two different foxes is the fox in Florida looks like he is on a diet of plants. The fox in wyoming looks like he has a squirel or some kind of animal in his mouth. Also their environment that they live in is completely different from each other hope it helps
Explanation:
The elements are arranged in horizontal rows, or periods, by order of increasing atomic number, which equals the number of protons in the atomic nucleus of each element.
Answer:
0.497 moles/L
Explanation:
The reaction that takes place is:
- C₃H₆O₃ + NaOH → C₃H₅ONa + H₂O
First we c<u>alculate the moles of lactic acid in 0,821 g</u>, using its molar mass:
- 0,821 g ÷ 90 g/mol = 9,122x10⁻³mol lactic acid
<em>One mole of lactic acid reacts with one mole of sodium hydroxide</em> (it is a monoprotic acid), so in 18,34 mL of NaOH solution there are 9,122x10⁻³moles of NaOH:
- 18.34 mL ÷ 1000 = 0,01834 L
- 9,122x10⁻³mol ÷ 0,01834 L = 0.497 moles/L
It is fresher because of new transportation techniques and refrigerated trailers.
Answer: the first and fourth
Explanation:
Ripening and rotting can be explained as chemical changes in chemistry. The other two answers are physics-related. Venus rotates in an opposite direction because it has like forces with mercury, so it repels it, causing it to turn away. This is electromagnetic force, something definitely not directly related to chemistry. The 200-pound person problem has to do with weight, mass, and gravitational force, which is mainly in physics.
