Answer:
Explanation:
The triple point of carbon dioxide is 5.11 atmosphere at -56.6 degree celsius . At pressure greater than 5.11 , solid carbon dioxide liquefies , as it is warmed. At pressure lesser than 5.11 atmosphere , it will go into gaseous state without liquefying . Excessive pressure helps liquification process.
So maximum pressure required is 5.11 atmosphere. Beyond this pressure , solid CO2 will liquify.
conduction is the transfer of energy by the movement of currents(it is true)
Answer:
C. 33.6L
Explanation:
Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.
To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:
<em>Moles H2:</em>
3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced
<em>Volume:</em>
PV = nRT
V = nRT / P
<em>Where P is pressure = 1atm at STP</em>
<em>V is volume = Our incognite</em>
<em>n are moles of the gas = 1.50 moles</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 273.15K</em>
<em />
V = nRT / P
V = 1.50mol*0.082atmL/molK*273.15K / 1atm
V = 33.6L
<h3>C. 33.6L</h3>
Answer:
Explanation:
(a) Convert pounds to kilograms.
(b) Calculate the dose
Answer:
If the data is given we can find out the density, melting point and solubility by using the formula given below.
Explanation:
Density is defined as mass of the substance per unit volume of the solution and its formula is p = mass / volume. We can calculate melting point by noting the temperature at which the particular substance starts melting. Solubility refers to the maximum amount of a substance or solute that can be dissolved in a solvent at a given temperature. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g we get solubility in g or in 100g.
