Answer: 0.529 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.998 atm
= final pressure of gas = ?
= initial volume of gas = 2 L
= final volume of gas = 3.5 L
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Thus the pressure if it is brought to a higher altitude where it now occupies 3.5 L and is at 12.0 °C is 0.529 atm
Cheeze is the most one i hope it helps
Take a look at their electronegativity values for this one. Electronegativity is the relative attraction that a atom in a molecule has for the shared pair of electrons in a covalent bond<span>. Salt is Sodium Chloride which is NaCl. Na has an electronegativity value of 0.93. Cl has an electronegativity value of 3.16. The difference between the two is 2.23. This is much higher than 1.7 (a pure covalent bond e.g. Oxygen-Oxygen bond O2) therefore it is a highly ionic compound. If this was less than 1.7 it would be a polar covalent molecule. </span>
Answer:
A scientific problem is something you don't understand but you can do an experiment to help you understand. Scientific problems are usually based on observation of scientific phenomena. Here is some advice to help you identify a scientific problem you can address by designing your own experiment.
Explanation:
Example of a scientific problem are Clean Drinking Water.
Answer:
The answer to your question is: Cp = 0.129 J/g°C
Explanation:
Data
mass = 955 g of tungsten
T1 = 18°C
T2 = 100°C
Q = 10180 Joules
Cp = ?
Formula
Q = mCpΔT
Clear Cp from the equation
Cp = Q / mΔT
Substitution
Cp = 10180 / (955(100-18))
Cp = 10180 / (955(82))
Cp = 10180 / 78310
Cp = 0.129 J/g°C
