Hey there!


Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)

Calcium and bromine have formed a bond. Leading up to this, calcium gave up electrons. It was a(n)
scZoUnD [109]
Leading up to this, calcium gave up 2 valence electrons and thus was denoted as a cation. These 2 electrons were transferred to bromine, which received an overall negative charge because of the addition of 2 valence electrons in its valence shell, and thus formed a negatively charged ion, an anion.

Both formed an ionic bond, due to the electrostatic charge of attraction between the 2 oppositely charged ions. If many ions of Ca and Br are present and numerous ionic bonds have formed it will undergo an arrangement which is that of an ionic lattice, type of structure.

Is this an example of physical or chemical weathering?<br><br><br> chemical<br><br><br> physical
skelet666 [1.2K]

Answer:

Physical

Explanation:

because the erosion of the canyon did not change any of the chemical attributes of the rock it only changed the appearance. it may have changed the color which is an example of chemical properties but in this case, it is physical. But in other cases, you would refer to this type of weathering as mechanical weathering.

Answer:

C. Br and Cl

Explanation:

The pair that will share electrons when a bond forms between them is Br and Cl.

When electrons are shared between two atoms to form a bond, then the bond type formed is called a covalent bond.

  • A covalent bond forms between non-metals.
  • Br and Cl are non-metals
  • The electronegativity difference between the species must be very low or zero.
  • This is the case for the two non-metals.

What is the ph of 0.45m solution of the strong chloric acid HCIO3?​
AnnZ [28]

Answer:

pH = 0.35

Explanation:

For a strong acid, all of the acid dissociates into H3O+, and pH = -log[H3O+], where [H3O+] = [HClO3] = 0.45 M.
