Answer:
To prevent error or inaccuracy.
Explanation:
It is quite necessary to know the exact volume of distilled water used to dissolve the acid and also the exact volume of the solution transferred from the beaker to the Erlenmeyer flask because it is very important that an equal amount of acid and its conjugate base are put in our two beakers to prevent error or inaccuracy
Answer:
See explanation below
Explanation:
Water has the anomality of having the solid less dense than the liquid state. The reason for this is that the hydrogen bonds in the solid ice forces the molecule to occupy more room to properly have the stability afforded by the hydrogen bonds. That is the reason why ice floats on water.
The other interesting consequence of this anomality is that the slope of the solid/liquid phase boundary is negative since at higher pressures the ice can be changed to its liquid phase which can be seen from the negative slope of the solid/liquid boundary.
A) True
B) False
C) False
D) True
E) False
F) True close up to 4 ºC when the water molecules start to behave like other liquids, that is the density of the liquid decreases.
G) True
H) True ( repeated question)
These days, scientists all over the world use a standard system of measurements. It's the SI or metric system.
What about scientists in the United States, Liberia, and Burma ? These three countries are the only ones in the world that haven't adopted the metric system. What do THEY do ?Easy. When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using. But when they go to work, they use the same metric system that everyone else in the world is using.

IF THE FIRST ONE DOESN'T WORK TRY THE SECOND
1. They use the same measuring system (metric)2. Clearly and properly collect and record data, recording the procedure and results3. Releasing the data into the public, letting everyone have access to it

Light Spectrum:
Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio
I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
Answer:
- be or mg
Explanation:
because of the it is easier to remove electron from the outer most shell
