28. Students in a science class prepared flash cards so that they could quiz one another about the arrangement of the periodic table. One of the flash cards
contained information about two elements, Element Land Element M.
Atoms of Element Mhave two more
valence daction than atoms of Element
- Atoms of Elementare more active than
stoms of Element M
- Soth demente metal
The students had to use the information on the flash card to determine possible
positions of the two elements on a blank periodic table. Which periodic table
has the elements placed in locations that match the information on the flash
card?
F
H
N
G

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

answer; natural resources;

2b2t

explanation:

2b2t

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
