Answer:

The universe is expanding

Explanation:

As long as the amount of stuff doesn't go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there's too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.

What produces the large amount of energy released by a nuclear reaction?
Bingel [31]
Fusion power is the power generated by nuclear fusion processes. In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus. In doing so, they release a comparatively large amount of energy that arises from the binding energy, creating an increase in temperature of the reactants.

In a laboratory preparation room one may find a reagent bottle containing 5.0 L of 12 M NaOH. Write a set of instructions for th
kari74 [83]

<u>Answer:</u> The volume taken from the reagent bottle must be 72.91 mL

<u>Explanation:</u>

To calculate the volume of concentrated solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated solution  which is the reagent bottle.

M_2\text{ and }V_2 are the molarity and volume of diluted solution which is the solution to be prepared.

We are given:

M_1=12M\\V_1=?mL\\M_2=3.5M\\V_2=250mL

Putting values in above equation, we get:

12\times V_1=3.5\times 250\\\\V_1=72.91mL

Hence, the volume taken from the reagent bottle must be 72.91 mL
