By increasing the amount of energy produced by friction of the cloth can generate a electrical charge.
Answer:
These are the same element.
Explanation:
H = 1p + 1e
D = 1p + 1e + 1n
Protium (H) and deuterium (D) are isotopes of the same element (H).
If two atoms have the same number of protons, they are the same element.
If they have the same number of protons but different numbers of neutrons, they are isotopes.
Answer:
The central portion is called neutron.
Explanation:
An atom has a central part known as nucleus and outer shells.
The central nucleus contains protons (the positively charged sub atomic particle) and neutrons (the neutral sub atomic particle).
The outer portion has negatively charged sub atomic particle known as electrons.
The atomic number of an element is the number of protons present in the nucleus.
Answer:
pH 8
Step-by-step explanation:
Red cabbage contains a compound called <em>anthocyanin</em>.
It produces different colours depending on the pH of the solution.
In the image below, you can see that the cabbage indicator is blue between pH 7 and pH 9, so a possible pH for your solution is pH 8.
