Answer: 2.78 L
Explanation:
Given that,
Original volume V1 = 1.2 L
Original pressure P1 = 5.1 kPa
New pressure P2 = 2.2 kPa
New volume V2 = ?
Since pressure and volume are given while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
5.1 kPa x 1.2L = 2.2 kPa x V2
6.12 kPa L = 2.2 kPa x V2
V2 = 6.12 kPa L / 2.2L
V2 = 2.78 L
Thus, the new volume of the gas would be 2.78 Liters
0.025 g
Sig Fig applies only to numbers that not zero, only except when the zero is after the the number.
For example:
0.0255 is three sigfigs
0.0050 is two sig figs
0.0005 is one sigfig
There are a few that look like fluffy heaps of cotton. The ones I would assume you're talking about are Cumulus clouds.
Clouds on the ground are called fog.
601 expressed as an integer is 3.
An integer refers to a whole number, a number which do not contain any decimal point.
To express any given number as an integer, just count the number of significant figures in the number and write this down as a whole number.
Answer:
H2S(g) + 2OH^-(aq) --------> S^2-(aq) + 2H2O(l)
Explanation:
We know that the net ionic equation shows the major reaction that occurs in the reaction system.
The molecular reaction equation is;
H2S(g) + 2NaOH(aq) ------> Na2S(aq) + 2H2O(l)
The complete ionic equation is;
H2S(g) + 2Na^+(aq) + 2OH^-(aq) --------> 2Na^+(aq) + S^2-(aq) + 2H2O(l)
Net ionic equation;
H2S(g) + 2OH^-(aq) --------> S^2-(aq) + 2H2O(l)
