To analyze. Oml they won't let me add it unless I write more. Smh.
Answer:
sun rises in the east so to the right of the front of your house and sets to the left which is south.
Explanation: what i just said
The one that will dissolve most quickly is : D. a tablespoon of ultrafine sugar
Unlike any other type of sugar, ultrafine sugar tend to have smaller crystal size. Which means that this substance will dissolve easier if it put into liquid such as tea or water
hope this helps
Before proceeding, we should write the reaction equation to better understand what is happening:
2AgNO₃ + Na₂S → Ag₂S + 2NaNO₃
Now, we may apply the law of conservation of mass, due to which the total mass before a chemical reaction is equivalent to the total mass after a chemical reaction. Therefore:
Mass of silver nitrate + mass of sodium sulfide = mass of silver sulfide + mass of sodium nitrate
Mass of silver nitrate + 156.2 = 595.8 + 340
Mass of silver nitrate = 779.6 grams
Answer:
Explanation:
q= mc theta
where,
Q = heat gained
m = mass of the substance = 670g
c = heat capacity of water= 4.1 J/g°C
theta =Change in temperature=(
66-25.7)
Now put all the given values in the above formula, we get the amount of heat needed.
q= mctheta
q=670*4.1*(66-25.7)
=670*4.1*40.3
=110704.1
