How to get the absolute zero from the graph for Charles law in Celsius? In this case what would be my value? Please help need it
k0ka [10]

At time t = 273.15 °C, the x-intercept occurs. According to Charles' law, an ideal gas's volume decreases as its temperature rises. At t = 273.15 °C, the graph's x-intercept, volume approaches zero.

<h3>Charles law experiment: what is it?</h3>

Describe the Charles Law experiment. Gases have a tendency to expand when heated, according to Charles' law (sometimes referred to as the law of volumes), an experimental gas law. The Kelvin temperature and the volume will be directly proportional when the pressure on a sample of the a dry gas is held constant, according to a current interpretation of Charles's law.

<h3>Which laws—Charles and Boyles—have similarities?</h3>

Boyle's law is formulated for systems with constant temperature, whereas Charles' law is formulated for systems with constant pressure.

Which substance can be broken down by chemical means
Maru [420]

Answer:

1. Ammonia  

Step-by-step explanation:

Ammonia, NH₃, is a <em>compound</em> of nitrogen and hydrogen.

Thus, it can be broken down by chemical means into the <em>elements</em> nitrogen and hydrogen.

The other options are <em>wrong</em>, because Al, Sb, and Pb are elements. They cannot be broken down chemically into simpler substances.

Calculate the molarity of 90.0 mL of a solution that is 0.92 % by mass NaCl. Assume the density of the solution is the same as p
jeka94
Answer is: molarity is 0,155 M.
V(solution) = 90,0 mL = 0,09 L.
ω(NaCl) = 0,92% ÷ 100% = 0,0092.
d(solution) = 1 g/mL.
m(solution) = V(solution) · d(solution).
m(solution) = 90 mL · 1 g/mL = 90 g.
m(NaCl) = 90 g · 0,0092 = 0,828 g.
n(NaCl) = 0,828 g ÷ 58,4 g/mol.
n(NaCl) = 0,014 mol.
c(solution) = 0,014 mol ÷ 0,09 L.
c(solution) = 0,155 mol/L.

12. Convert 600 mg to grams. Show your work.
nadya68 [22]

Answer:

600 milligrams=0.6 grams

Explanation:

1 milligram=0.001 grams and 1 gram= 1000 milligrams

So, to convert milligrams to grams, multiply the mg value by 0.001 or divide by 1,000.

Example:

If you want to know how many grams 300 mg is, you would divide 300 by 1,000, which would get you 0.3 grams.
