The nonmetals, as s class of elements contains both solids and gases at room temperature.
Some gases classed as nonmetals are : hydrogen, helium, oxygen, nitrogen, fluorine, neon, or radon and many others. An example of a solid that is a nonmetal is sulfur.
Kinetic energy id energy of motion and is equal to 1/2mv^2 where m = mass and v = velocity.
So the answer is a salmon leaping up a waterfall.
Answer:
If a material gains electrons, its going to be Negatively charged
If a material loses electrons, its gonna be positively charged.
Explanation:
Why?
This is because electrons are negative subatomic particles
Answer:
2 atm
Explanation:
Chemical reactions are carried out at a certain rate. Sometimes that rate is quite slow, so we want to speed things up, which is usually used by increasing temperature, increasing pressure or adding a catalyst (a substance that increases the rate without changing itself).
If this is the case, then, when writing a chemical equation, we state these special conditions over a right arrow.
Now let's look at the answers:
- 25°C is a value and unit of temperature
- ∆ is a symbol that denotes change
- 2 atm is a value and unit of pressure (atmosphere is old unit for pressure)
- Pt is a chemical symbol for platinum, an element often used as a catalyst.
So, the correct answer is C) 2 atm
