Beryllium iodide is BeI2. The molecular weight of BeI2 is 2(9.01) + 126.90 = 144.92g/mol. So, in 0.02 moles of BeI2, you have 0.02 * 144.92 = 2.9 grams (3 g if you want to stick to significant figures)
Hi there!
The answer is D.
Could you please Brainliest me please?
Answer:
See the answer below, please.
Explanation:
The bonds formed between metals and nonmetals are called ionics. These occur between atoms with electronegativity difference. Example: NaCl (Sodium Chloride)
Instead, covalent bonds are formed between two nonmetals (one or more electron pairs are shared). Example: H202 (hydrogen peroxide).
In the case of metal formed bonds, they are called metallic.
He decided that atoms could not be separated into smaller pieces, they can. Please mark Brainliest!!!
This is going to be a true answer so put true
