Answer: The entire water/ice solution is at the melting/freezing point, 32°F (0°C). Adding rock salt — or any substance that dissolves in water — disrupts this equilibrium.

Explanation: Hope this helps! Have a great day :)

How are energy storage molecules affected if there is LESS carbon dioxide?
kipiarov [429]

Answer:

When there is less carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available for producers making energy storage molecules. When there is more sunlight, producers can make more energy storage molecules from the carbon in carbon dioxide.

Hope this helps.

Explanation:

44.5 divided by 25.2 = 1.765873 (i used calculator to double check)

1.765873 x 0.967 = 1.707599191 (used calculator)

Francium is the most reactive element in Group 1.
natali 33 [55]

Answer:

Francium is hypothesized to be the most reactive metal, but so little of it exists or can be synthesized, and the longest half-life of its most abundant isotope is 22.00 minutes, so that its reactivity cannot be determined experimentally.

Explanation:

Francium is an alkali metal in group 1/IA. All alkali metals have one valence electron. As you go down the group, the number of electron energy levels increases – lithium has two, sodium has three, etc..., as indicated by the period number. The result is that the outermost electron gets further from the nucleus. The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive.

Experimentally speaking, cesium (caesium) is the most reactive metal.

What are Newton's three laws of motion? Are they correct?​
muminat

Answer:

Explanation:

Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.

Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.

Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.

Newtons third law of motion states that to every action there is equal and opposite reaction.

Hope it will be helpful :)
