MgCl2 is an ionic compound because chemical bonds in the molecule are formed by the transfer of electrons among Mg and Cl atoms.

<h3>What is chemical bond ?</h3>

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."

The positively charged protons in the nucleus and the negatively charged electrons in its orbit are attracted to one another by the basic electromagnetic force.

Why does increasing the number of trials increase confidence in the results of the experiment?
valkas [14]
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>

Answer:

1.G → giga  

2.da → deca

3.n → nano

4.m → milli

5.M → mega

6.k → kilo

7.c → centi

8.d → deci

9.h → hecto

10.µ → micro

Explanation:

In descending order:

1.G → giga (1 . 10⁹)  

5.M → mega (1 . 10⁶)

6.k → kilo (1 . 10³)

9.h → hecto (1 . 10²)

2.da → deca (1 . 10¹)

8.d → deci (1 . 10⁻¹)

7.c → centi (1 . 10⁻²)

4.m → milli (1 . 10⁻³)

10.µ → micro  (1 . 10⁻⁶)

3.n → nano (1 . 10⁻⁹)

In example:

1000000 m = 1 Mm

0,000000001 m = 1 nm

EASY POINTS EASY QUESTION ​
shepuryov [24]

Answer:

The safety button doesn't click before the jar has been opened because it shows a sign of freshness. Once you have opened it there is no way to make it click again.

If bacteria gets stored in the jar they will produce gas. If the button does not pop or click after opened that is a sign that it may not be so safe to eat. Clicking shows that there is still vacuum to the jar.
