I think it might be C because we don't have too much room to dispose of these things with no harm to people
Answer:
Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium, and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame. When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colors. Each metal gives a characteristic flame emission spectrum
Answer:
Go for it!
Explanation:
You only live once, seriously just go up and talk to him. Say something like, "Hey, you seemed cool I just wanted to say hi. Do you have an ig?" :) you won't regret it.
Answer:
(Co,Fe)As2
Explanation:
The formula of the mineral safflorite, a compound made of cobalt, iron, and arsenic is (Co,Fe)As2. This itself is the imperical formula, it cannot be divided any further
Oxygen, glucose and starch
Oxygen and glucose are produced during photosynthesis. Glucose is then stored as starch.
