Answer:
5.The limiting reactant is completely used up in the reaction
Explanation:
The limiting reactant is completely used up in the reaction is the correct answer because a limiting reactant is a reactant in chemical reaction that is completely consumed or used up in the chemical reaction. Limiting reactant when it is completely used up limits the amount of products that will be formed. The reaction will be halted or will stop when the limiting reactant is totally used up.
<span>The equation that describes the problem is Fe(NO3)3(aq) + 3NaOH(aq) ---> Fe(OH)3(s) + 3 NaNO3(aq)
The Net ionic equation is written as follows:
Fe^3(aq) + 3NO3-(aq) + 3Na+(aq) + 3OH-(aq) ---> Fe(OH)3(s) + 3Na+(aq) + 3NO^3-(aq)</span>
Answer:
Magnetic: Magnet being pulled to a metal surface- non- contact force
Friction: skateboard slowing down on a rough surface- contact force
Gravity: Ball falling to the ground - non-contact force
Electrical: Charged balloon pulling up on arm hair - non- contact force
Tension (pull): people playing tug-of-war - contact force
Applied (push): a person pushing a toy car - contact force
Air resistance: wind pushing on the sail of a sailboat - contact force
Spring: springs being pushed together -contact force
Explanation:
A contact force is a type of force that can only act when two bodies touch other physically. Examples of this include a push or a pull.
A non-contact force is a type of force that can only act when two bodies do not touch other physically. Examples include; electric force, magnetic force, etc.
Answer:
the answer is c)Irregular galaxies contain many newly-formed stars.
Explanation:
In order to know this you need to have in mind the following: Normaly, <span>speed of gas molecules depends on temperature. That means that the lower the temperature, the slower the molecules. For this case, the slowest is the closest to absolute zero. So your answer is 0.0005 m/s </span>
