What is the bond between Ca and Cl

Chemistry
1 answer:
gtnhenbr [62]3 years ago
4 0

ionic bond is formed between ca and cl forming molecule cacl2 ca has 2 velancy and cl has one velancy (ca has 2 electrons in its outer most shell while cl has 1 electron vecancy in its outermost shell). So ca would make bond with 2 cl atoms

can a light object that was hit with a small force accelerate as rapidly as a heavier object hit with a big force? why or why no
Tcecarenko [31]

The acceleration is defined by force divided by the mass of the object. So, When the smaller object is hit by a small force, it can produce equal acceleration which is same as that of the bigger body hit with large force.

<h3><u>Explanation:</u></h3>

Force is defined as the product of the mass of the body its applied to and the acceleration of the body in the direction of the force. So acceleration is force divided by the mass of the body.

Let the mass of the smaller body be m and that of the larger body be M.

The smaller force applied on the smaller body be f and the larger force applied on the larger body be F.

So acceleration of the larger body = F/M.

Acceleration of the smaller body = f/m.

For the accelerations to be same,

F/M = f/m.

Or F/f = M/m.

So when the ratio of the force applied on two bodies is in ratio of their masses, the acceleration becomes equal.

The vapor pressure of water at 50.0 c is 12.33 kpa. What is this value in millimeters of mercury?
kramer

Answer:

  • <u>92.48 mmHg</u>

Explanation:

You need the conversion factor to convert the value of 12.33 kPa to milimiters of mercury, mmHg.

The converstion factors are looked at tables, which today you can find in internet.

Since the conversions between kPa and atm and between atm and mmHg are more widely known, I will show the conversion using those relations:

  • 1 atm = 101.325 kPa
  • 1 atm = 760 mmHg

⇒ 101.325 kPa = 760 mmHg

Then, dividing both sides by 101.325 kPa you get the conversion factor:

  • 1 = 760 mmHg / 101.325 kPa

Now, multiply 12.33 kPa by that conversion factor:

  • 12.33 kPa × 760 mmHg / 101.325 kPa = 92.48 mmHg ← answer

Evaluate (714 mm )/(37 s ) to three significant figures and express answer in si units using an appropriate prefix.
romanna [79]

The SI base units for length is meter (m) and for time is seconds (s).

The given ratio is \frac{714 mm}{37 s}

\frac{714 mm}{37 s} = 19.297 mm/s \simeq 19.3 mm/s

Converting mm/s to m/s as:

Since, 1 mm/s = 0.001 m/s

So, 19.3 mm/s = 0.0193 m/s

Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of \frac{714 mm}{37 s} to three significant figures and answer in SI units is 0.0193 m/s.
