Answer:

As water is cooled its density increases 4 degrees Celsius is reached

Explanation:

  • Thus water being a solvent has various physical and chemical properties it expands as gs and contracts as icy layers until it reaches a freezing point by approx 9% of water density.
  • Schooling of a substance causes water to slow down at a faster rate occupying a smaller rate as hot water is less dense than the room temperature as cold water is denser and will freeze at room temperature.
  • Thus water has to condense to a certain point to produce the desired effects.

Acellus<br> How many grams of strontium<br> (Sr, 87.62 g/mol) are in 2.92<br> moles of strontium?
saul85 [17]

Answer:

There are 255, 85 grams of Strontium in 2,92 moles.

Explanation:

We perform a simple rule of three to calculate the number of grams, knowing that one mole of Sr weights 87, 62 grams:

1 mol Sr---------87, 62 grams

2,92 mol Sr-----x=(2,92 mol Sr x-87, 62 grams)/1 mol Sr= 255,8504 grams

A motor cyclist starts from rest and reaches a speed of 6m/s after travelling with uniform acceleration for 3s. What is his acce
choli [55]

Answer:

2m/s²

Explanation:

When an object starts or at its state of rest it has an Initial speed U = 0

Final speed = 6m/s

total time taken for the acceleration = 3s

Acceleration =?

Acceleration is the change in velocity (speed) with time

OR

Time rate of change of velocity

Acceleration = <u>Change in Speed(velocity)</u>

Time taken

Hence,

Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>

t

a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>

3

a = <u>6</u><u> </u><u> </u>

3

a = 2m/s²

What is ionization energy? What is fist ionization energy?
Flura [38]
The ionization energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.The first ionisation energy is the energy required to remove one mole of the most loosely held electrons from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+. I hope this helps :3
