It means the system absorbs energy from surrounding objects; usually, but not always, involving heat
Answer:
Ionic bond
Explanation:
This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge. The sodium cation (Na+) and the chlorine anion (Cl-) are attracted to one another to form sodium chloride, or table salt.
Answer:
We have the final answer as
<h2>0.8 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass of pumpkin = 8 g
volume = 10 cm³
It's density is
![density = \frac{8}{10} = \frac{4}{5} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B8%7D%7B10%7D%20%20%3D%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%5C%5C%20)
We have the final answer as
<h3>0.8 g/cm³</h3>
Hope this helps you
Answer:
Kinetic energy has its determining factors and those are mass and speed or velocity
whereas the determining factors of potential energy are height, distance and mass.
EXAMPLE OF K.E
kinetic energy could be flowing water...
EXAMPLE OF P.E
potential energy is the water that is present at the top of the hill.
The answer is [OH⁻] = 1 x 10⁻⁴.
[OH⁻] = H₂O ÷ [H₃O⁺]
[OH⁻] = 1 x 10⁻¹⁴ / 1 x 10⁻¹⁰
[OH⁻] = 10⁻⁴
