Answer:
K = 351.3
Explanation:
The relationship between the Celsius scale and kelvin scale is;
K = 273 + C
Since the Celsius temperature = 78.3
The kelvin temperature is given as;
K = 273 + 78.3
K = 351.3
Answer:
Temperature is not a chemical change because when a substance changes in temperature, its chemical makeup is not changing.
Answer:
The correct answer is: <em>The addition of water will change the concentration of the substances in equilibrium.</em>
Explanation:
For chemical reactions, the equilibrium constant is defined as the ratio between the concentration of products and reactants. In this expression pure substances should not be written, like pure liquids and gases. Since water is a pure liquid should not appear in the equilibrium. However, water is the solvent of all the solutes or substances in the reaction, thus the addition of water will make all the substances to be diluted. Also, because of the Le Châtelier principle the equilibrium should be re-establish and the concentrations whitten in the equilibrium constant should change too.
A root beer float is a combination of root beer, ice cream and foam.
The three states are:
a) Root beer is a liquid wherein the particles move freely and tend to take the shape of the container.
b) Ice cream is a solid in which the particles have a fixed shape and held strongly in place. Unlike liquids, solids retain their shape.
c) Foam is a gas which is produced by the reaction of root beer with the ice cream. Gas particles move quickly and fill the container they occupy.
Answer:
a) CH4 (g) (1 mole) + H2O (g) (1 mole) = CO (g) + 3H2 (g) (3 moles).
b) 3/1 or 3 will be the conversion factor used to convert moles of methane and the moles of hydrogen.
c) Based on the given mole-mole relation,
The number of moles of hydrogen produced by 1 mole of CH4 or methane is 3 moles. Therefore, the number of moles of hydrogen produced from 7 moles of CH4 would be,
3/1 * 7 = 21 moles.
d) The formation of 3 moles of hydrogen is taking place from 1 mole of water vapor or H2O. Therefore, the number of moles of water vapor required to produced 100.50 moles of hydrogen would be,
1/3 * 100.50 moles = 33.5 moles.
