Answer:
6 sig figs
Explanation:
sig figs are numbers that are more than 0, but in this case, after the decimal, the 0's at the end count as sig figs as well
Answer:
It’s false
Explanation:
it could be true if the question mentioned alkaline solution
Answer:
The pressure of the gas sample will be 0.954 atm.
Explanation:
Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. That is, if the pressure increases, the volume decreases; conversely if the pressure decreases, the volume increases.
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
To determine the change in pressure or volume during a transformation at constant temperature, the following is true:
P1 · V1 = P2 · V2
That is, the product between the initial pressure and the initial volume is equal to the product of the final pressure times the final volume.
In this case:
- P1= 0.609 atm
- V1= 19.9 L
- P2=?
- V2= 12.7 L
Replacing:
0.609 atm* 19.9 L= P2* 12.7 L
Solving:
![P2=\frac{0.609 atm* 19.9 L}{12.7 L}](https://tex.z-dn.net/?f=P2%3D%5Cfrac%7B0.609%20atm%2A%2019.9%20L%7D%7B12.7%20L%7D)
P2= 0.954 atm
<u><em>The pressure of the gas sample will be 0.954 atm.</em></u>

Answer:
Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
Explanation:
For classification, the protists are divided into three groups: Animal-like protists, which are heterotrophs and have the ability to move. Plant-like protists, which are autotrophs that photosynthesize. Fungi-like protists, which are heterotrophs, and they have cells with cell walls and reproduce by forming spores.
