Answer:
answer is 18g
Explanation:
acording to mass formula
mass=concentration x volume
When it reaches the boiling point. When a substance reaches their boiling point, they change from liquid state to vapor state. Alcohol has a boiling point of around 78°C, so when you heat liquid alcohol to that temperature, it'll change to vapor.
Answer:
The proton and electrons are equal,
15protons and 15electrons
Explanation:
An atom is the smallest electrical neutral particle of an element so it means that every atom have same number of protons and electrons.
Answer:
False.
Explanation:
1. Most liquids do not have ionized atoms or particles within them, as the state of matter does not really allow that to freely happen.
2. Liquids may not have a definite shape, however, they have a definite volume. No matter the container you pour them into, their volume remains constant.
3. Liquids are not good conductors of electricity. Take for example water. Pure water does not conduct electricity
Hence, the statement is false with regards to liquids. However, it is true when talking about the foruth state of matter - Plasma
First let's find how much 30Si in nature: 100%-92.2%-4.67%=3.13%
Average M = M(28Si) * 0.922 + M(29Si) * 0.0467 + M(30Si) * 0.0313;
Let's substitute all the values we know:
28.09 = 27.98*0.922 + 28.98*0.0467 +x * 0.0313;
x = 30.03 g/mol
