The answer is (4) synthesis. Synthesis reaction means that two or more reactants combine directly to one production. Substitution or single replacement means that one element of a compound is replaced by another element. Double replacement means that two ionic reactants exchange ions to form two new productions.
Answer:
3 years
Explanation:
Given data:
Initial amount of sample = 160 Kg
Amount left after 12 years = 10 Kg
Half life = ?
Solution:
at time zero = 160 Kg
1st half life = 160/2 = 80 kg
2nd half life = 80/2 = 40 kg
3rd half life = 40 / 2 = 20 kg
4th half life = 20 / 2 = 10 kg
Half life:
HL = elapsed time / half life
12 years / 4 = 3 years
Answer:
Chemical name for As2S3 is Arsenic sulfide
Explanation:
See image below for the lewis structure of acrolein
Answer:
Explanation:
1. Density from mass and volume

2. Volume from density and mass

3. Mass from density and volume

4. Density by displacement
Volume of water + object = 24.6 mL
Volume of water =<u> 12.8 mL</u>
Volume of object = 11.8 mL

Your drawing showing water displacement using a graduated cylinder should resemble the figure below.
