What are the answer choices?
Answer:
Percent yield = 114.5%
Explanation:
Given data:
Calculated amount of product/ theoretical yield = 55 g
Actual amount of product after performing reaction = 63 g
Percent yield = ?
Solution:
Formula:
Percent yield = ( actual yield / theoretical yield )× 100
by putting values,
Percent yield = (63 g/ 55 g)× 100
Percent yield = 114.5%
Answer:
1, 1, 2, 3
Explanation:
The numbers 1 and 8 both have 1 sig. fig.
The number 13 has 2 sig. figs.
The number 104 has 3 sig. figs.
Answer:
Tetrahedral electron geometry and trigonal pyramidal molecular geometry.
Explanation:
The Lewis structure is shown in Figure 1.
The central N atom has three bonding pairs and one lone pair, for <em>four electron groups</em>.
VSEPR theory predicts a tetrahedral electron geometry with bond angles of 109.5°.
We do not count the lone pair in determining the molecular shape.
The molecular geometry is trigonal pyramidal (see Figure 2).
Answer:
D
Explanation:
I think it is D. Think about it- if a human jumps, they are less than the gravitational force. But, if you are greater than the gravitational force, I think you will go into space.
