Two common materials we encounter in our daily lives are radiator coolant in automobiles and dry ice. The coolant in an automobi

le radiator, a solution of antifreeze (a glycol such as ethylene or propylene glycol) and water, freezes at 39°C and boils at 110°C. The temperature of the dry ice (solid carbon dioxide) used in some ice cream vending carts is –78°C. Convert the boiling point of radiator coolant (110°C) to degrees Fahrenheit. Convert the temperature of dry ice (–78°C) to the Kelvin scale.

Answer:

See explanation

Explanation:

Using the formula

°C = (F-32) × 5/9

Where;

°C = temperature in degrees centigrade

F= temperature in Fahrenheit

F= (9/5 ×°C) +32

F= (9/5 × 110) + 32

F= 230°F

To convert -78°C to Kelvin

-78°C + 273 = 195 K

Consider the following reaction at equilibrium: 2NH3 (g) N2 (g) + 3H2 (g) Le Châtelier's principle predicts that the moles of H2
Lilit [14]

Answer:

A decrease in the total volume of the reaction vessel (T constant)

Explanation:

  • Le Châtelier's principle predicts that the moles of H2 in the reaction container will increase with a decrease in the total volume of the reaction vessel.
  • <em><u>According to the Le Chatelier's principle, when a chnage is a applied to a system at equilibrium, then the equilibrium will shift in a way that counteracts the effect causing it.</u></em>
  • In this case, a decrease in volume means there is an increase in pressure, therefore the equilibrium will shift towards the side with the fewer number of moles of gas.

How much heat does it take to melt 5.0g solid copper?
Leya [2.2K]

Answer:

Q=1.04kJ

Explanation:

Hello,

In this case, for latent heat (phase change) we need to consider the enthalpy associated with the involved process, here, melting or fusion; thus, the enthalpy of fusion of copper is 13.2 kJ/mol, therefore, the heat is computed as:

Q=m\Delta H_{fus}

Nevertheless, since the given enthalpy is per mole of copper, we need to use its atomic mass to perform the correct calculation as follows:

Q=5.0g*\frac{1mol}{63.54}* 13.2\frac{kJ}{mol}\\ \\Q=1.04kJ

Which is positive as it needs to be supplied to the system.

Best regards.

I need this project using large intestine, if you help me with one of them or everything I will give you brainest. Please help a
Lelu [443]

Answer:

large intestine is right below the stomach and gallbladder and has the small intestine in the middle

works mainly with the digestive system

The large intestine gets rid of the undigested food that the small intestine could not absorb and reabsorbs water from the digestion

other organs include:

pancreas

small intestine

gallbladder

liver

stomach

esophagus

salivary glands

the function of the large intestine is to get rid of waste, absorb water, and absorb any nutrients which did not get absorbed in the small intestine
