<span>Answer:
CH3-CH2-0-CH2-CH3
that is diethyl ether
mechanism is SN2</span>
Isotopes are two atoms with the same number of protons, but a different number of neutrons. Because they have the same number of proton they are atoms of the same element, but with different masses.
so, the answer is c.
i hope this will help you
the answer will there for be ironic
Answer:
128.4 g
Explanation:
Step 1: Given data
- Mass percent of element X in X(NO₃)₂: 52.55%
- Mass of the element X in the sample: 67.50 g
Step 2: Determine the total mass of the sample
The mass percent of element X in X(NO₃)₂ is 52.55%, that is, there are 52.55 g of X every 100 g of X(NO₃)₂. Then, the mass of X(NO₃)₂ that contains 67.50 g of X is:
67.50 g X × 100 g X(NO₃)₂/52.55 g X = 128.4 g X(NO₃)₂
