The reaction equation is:
Li + Br → LiBr
39 grams of Li = 39 / 7 = 5.57 moles of lithium
41.5 grams of Br = 41.5 / 80 = 0.52 mole of bromine
The least reactive metal is lead, since it reacted with none of the salt solutions.
Answer:
380 mL is the new volume
Explanation:
At constant pressure.
V₁ / T₁ = V₂ / T₂
Temperature must be in Absolute Values (T°K = T°C + 273)
-125°C + 273 = 148 K
31°C + 273 = 304 K
185 mL / 148 K = V₂ / 304 K
V₂ = (185 mL / 148 K) . 304 K → 380 mL
The amount of atoms in each level and the positive and negative atoms in each level also
Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
