Answer: D
Explanation:
Because velocity is speed
Explanation:
Atomic number , protons and electrons have the same value / their value is same .
But for the neutron there is no specific technique. You have to remember the neutrons of every element
Answer:
D: a heterogeneous mixture with components of varying sizes
Heterogeneous mixture is a combination of substances that doesn't have uniform composition and properties. Just by looking at the mixture you can differentiate the compounds because they are so different. Using a sieve, allows the components with different sizes to separate, while one is retained, the others can pass the holes in the sieve.
Explanation:
Answer:
Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other.
Are you asking for a specific atom or just the general definition?
The general definition of alpha decay is the loss of two protons and two neutrons from a nucleus. (Also equal to a helium atom!) This decreases the total mass number by 4 and the atomic number by 2.
