Step 1:
           Write down Chemical formula, Overall compound is neutral, so overall charge on it is zero,

                                              Na₃AsO₂  =  0

Step 2:
           Write down the oxidation state of known elements, i.e O.S of Na is +1, and O.S of O is -2, Now put these values in above formula.

                                        (+1)₃ + As + (-2)₂  =  0

Step 3:
           Now solve for As,

                                        (+1)₃ + As + (-2)₂  =  0

                                        +3 + As - 4  =  0

                                         As  =  4 - 3

                                         As  = +1
Result:
           
Oxidation state of Arsenic in Na₃AsO₂ is +1.

A cylinder with a moveable piston contains 0.552 mol of gas and has a volume of 259 mL . Part A What will its volume be if an ad
Naddik [55]

Answer:

The new volume will be 367mL

Explanation:

Using PV = nRT

V1 = 259mL = 0.000259L

n1 = 0.552moles

At constant temperature and pressure, the value is

P * 0.000259 = 0.552 * RT ------equation 1

= 0.552 / 0.000259

= 2131.274

V2 = ?

n2 = 0.552 + 0.232

n2 = 0.784mole

Using ideal gas equation,

PV = nRT

P * V2 = 0.784 * RT ---------- equation 2

Combining equations 1 and 2 we have;

V2 = 0.784 / 2131.274

V2 = 0.000367L

V2 = 367mL

What phrase from the Preamble justifies a law like the Affordable Care Act?
Alexandra [31]
<span>The Affordable Care Act which was instated during Barack Obama´s presidency and is sometimes known as Obamacare is justified by the phrase ¨for the general welfare¨ in the Preamble. This concept can be defined as holding the US government responsable for providing care for all people, not just a few elites. Therefore the Affordable Care Act, which aims to increase access to healthcare to all Americans is adhering to this phrase.</span>

Sawing a board in half is an example of a chemical change
koban [17]

Sawing a board in half is a physical change not a chemical change the board doesnt change wood or whatever material it is is still would still be wood
If it were burned it would be a chemical change but its properties stay the same atomically so thats why its not a chemical change.
