Answer:10times
Step-by-step explanation:
Group 1 elements are comprised of: (1) hydrogen, sodium, lithium, potassium, rubidium, caesium, and francium. The tendency of these atoms is to lose one of their electrons such that they become charge +1.
Group 5 elements contains the vanadium, niobium, tantalum, and dubnium. It is quite hard to predict the oxidation number of these elements such that it will be hard to determine the number of atoms needed to react with them. Their valence electron is 5, and they react by losing them. Hence, in order to reach the octet rule, 3 group 1 elements should be reacted.
Answer:
B) Cube
Step-by-step explanation:
A) square pyramid has one square base and 4 congruent triangles
B) Cube has 6 congruent squares
C) Rectangular pyramid has one rectangle base and 4 congruent triangles
D) Rectangular prism has 3 sets of rectangles; total of 6 rectangles
Answer:
360 in.
Step-by-step explanation:
In order to get this answer, you have to multiply 5 and 8 by 3 because the drawing is 1/3 of the actual flag.
5 x 3 = 15
8 x 3 = 24
So, 24 x 15 = 360 in.
Hope this helps! :)
