Answer:100c
Explanation:
water boils at 100c the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure
Answer: m = 17.5 g Cl
Explanation: To find the mass of Cl we will need to convert the moles of Cl to mass using the relationship of 1 mole = molar mass of Cl.
0.500 mole Cl x 35 g Cl / 1 mole Cl
= 17. 5 g Cl
Arrhenius was seeking to understand the causes of ice ages.
He was the first to use basic principles of physical chemistry to calculate estimates of the extent to which increases in atmosphere carbon dioxide increases Earth's surface temperature through the Arrhenius effect. Arrhenius's paper was the first to quantify the contribution of carbon dioxide to the greenhouse effect and to speculate whether variations in the atmospheric concentration of carbon dioxide have contributed to long-term variations in climate.
Explanation:
Structureless rocks like granite and other intrusive rocks tend to weather into characteristic rounded shapes through this process
Hrxn = Q reaction / mol of reaction
mol of reaction = M * V = 10 * 1 = 10 mmol = 0.01 mol
Q water = m * C * (Tf - Ti)
= (10 + 10) (4.184) (26-20) = 502.08 J
Q reaction = - Q water = -502.08 J
Hrxn = -502.08 / (0.01) = - 50208 J = - 50.21 kJ/mol
