aswer: protactinium-234 is more dang erous than uranium
Answer: The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. ... increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
Hope this helps

Answer:
Volume of bacteria cell into Pico liters = 60.27 Pico liters
Explanation:
Given:
Volume of bacteria cell = 6.027 x 10⁻¹⁰ L
Find:
Volume of bacteria cell into Pico liters
Computation:
1 L = 10¹² Pico liters
So,
Volume of bacteria cell = 6.027 x 10⁻¹⁰ L
Volume of bacteria cell = 6.027 x 10⁻¹⁰ x 10¹² Pico liters
Volume of bacteria cell into Pico liters = 60.27 Pico liters
Answer:
a) Neutralisation
b) Combustion
c) Synthesis
d) Decomposition
e) Neutralisation
f) Double Displacement Reaction
h) Single Displacement Reaction
i) Double Displacement Reaction
j) Combustion
Explanation:
Synthesis is a reaction where various compounds/ elements react to form a totally new compound.
Decomposition is a reaction where a single compound breaks down into several components due to excessive heating or energy applied.
Single Displacement Reaction is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
Double Displacement Reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Combustion is a reaction where a compound/ element oxidises in the presence of Oxygen.
Neutralisation reaction is a reaction where an acid reacts with a base to form a salt.
Answer:
B
Explanation:
If something says always, you have to know for sure that it's true otherwise don't pick it. Covalent compounds have non-metals like carbon(s), oxygen(g), and bromine (l)
