Answer:
Option B
Step-by-step explanation:
The question can be solved without observing the masses and calculating them.
How?
- Periodic table law states that masses get increased in group and get decreased in period.
- Hydrogen is the 1st element so it has least mass.
Now
Only option B and D has Hydrogen at first.
Now coming to last elements Carbon and Gold
Gold is heavier as per periodic table.
So option B is correct
The perimeter is 20 because you just count how many squares are touching the sides
Answer:
Quadrant II
Step-by-step explanation:
(-5,6)
The x coordinate is negative so the quadrant is either 2 or 3
The y coordinate is positive so the quadrant is either 1 or 2
To make both happen, it must be in quadrant 2
Quadrant II
Equation of a line: y=mx+b
m=slope(-1)
b=y-intercept(-7)
y=-1x-7 or y=-x-7
12/3 cup chopped nuts
which simplified is 4 cups
