It is being reduced

Gaining an electron

23
Q

What kind of bond do redux reactions form?

A

Ionic

24
Q

In general, atomic radius increases moving (up / down) a group due to the increasing number of electron shells

A

Down

25
Q

In general, atomic radius (increases/ decreases) moving from left to right across a period due to increasing number of protons in the energy level.

A

Decreases

26
Q

Where would we find atoms with the biggest atomic radii

A

Bottom left

27
Q

A tissue contains a variety of cell types that work together to preform a special function

True or False

A

False tissue is similar cells

28

Water becoming vapor is Endothermic or Exothermic

A

Endothermic

32
Q

If heat is moving from surroundings into system it is. Endothermic or Exothermic

A

Endothermic

33
Q

In this type of reaction heat moves out of the system. Exothermic or Endothermic

A

Exothermic

36
Q

C⁸H¹⁸ + O² —> H²O + CO²
Type of reaction is this
How do we know

A

Combustion
Reactants always C,H,O
Products always H²O & CO²

37

Type of reaction

A

Decomposition

38
Q

Mg + O² —> MgO
Type of reaction

A

Synthesis

39
Q

CH³COOH + H²O —> CH³OO- + H³O+
which is the brønsted Lowry Acid / Base

A

CH³COOH is Bronsted Lowry Acid because it released (H) CH³COO

H²O Accepted an H so it is a Bronsted Lowry Base H³O+

40
