What would happen to our solar system if the Sun had an even greater mass than it currently does?
motikmotik

Answer: If the Sun had an even greater mass then it currently does, it would have a larger gravitational pull and since it's heat would be closer to Earth, both by magnitude and gravity, life on Earth wouldn't be possible and life on Mars would be reality. Also, when the sun would explode, it would have a larger supernova and possibly create a white dwarf (something that only happens to red supergiant stars when they die), with a gravitational force so strong it wold have two beams of light coming out it's north and south poles (like a black hole).

I hope this helps!

If you have a pitcher of lemonade and the recipe calls for 2 lemons and you decided to use 4, would this be considered diluted o
pantera1 [17]

Answer: This would be considered concentrated because if you're upping the recipe on your own accord, it would be way more sour, causing the lemonade to be more concentrated. It would be diluted if you added less than 2 lemons.

How many grams of NaCl (molecular weight = 58 Da) would you have to dissolve in 50ml to make a 2M stock solution? Answer:
Lerok [7]

Answer:

5.8 g

Explanation:

Molecular weight in Daltons is equivalent to the molecular weight in grams per mole.

The amount of NaCl required is calculated as follows:

(2 mol/L)(50 mL)(1 L/1000 mL) = 0.1 mol

This amount is converted to grams using the molar mass (58 g/mol).

(0.1 mol)(58 g/mol) = 5.8 g

Conservation of mass was discussed in the background. describe how conservation of mass (actual, not theoretical) could be check
rosijanka [135]

Conservation of mass can be checked in an experiment . There are three steps to do it in a best way:

1. Weigh all the equipment and materials required in the experiment before the experiment.

2. Avoid spillage and evaporation during the experiment.

3. Weigh all the equipment and materials after the experiment.

If the mass is conserved then weight from step 1 is equal to weight from step 3.
