The answer is 3 moles as per given balanced equation one mole Zn produces 1mole Hydrogen
when reacted with excess acid.
<span>So 3 moles Zn will give 3moles Hydroge</span>
Answer:
According to Thompson's model, Every atom consists of a positively charged sphere of radius 10-- 10m in which entire mass and positive charge of the atom are uniformly distributed inside the sphere electrons are embedded like seeds in watermelon. According Rutherford entire poistive charge and mass of the atom are concentrated in a tiny central core of the atom which is called atomic nucleus contains. Size of nucleus = 10-- 15m. The nucleus contains protons and neutrons. Negatively charged electrons revolve around the nucleus in circular orbits.
Explanation:
Answer:
Has a hydroxide concentration of 0.01M
Explanation:
When NaOH dissociates, it gives 1mol Na+ and 1mol OH- this multiplies the concentration value and we get 0.01×1= 0.01M
Answer:
The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.
the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.
