Answer:

Mass = 206.38 g

Explanation:

Given data:

Mass of calcium chloride = 80.0 g

Mass of silver chloride formed = ?

Solution:

Chemical equation:

CaCl₂ + 2AgNO₃ → Ca(NO₃)₂ + 2AgCl

Number of moles of CaCl₂:

Number of moles = mass/molar mass

Number of moles = 80.0 g/ 110.98 g/mol

Number of moles = 0.72 mol

Now we will compare the moles of CaCl₂ and AgCl

CaCl₂ : AgCl

1 : 2

0.72 : 2/1×0.72 = 1.44 mol

Mass of silver chloride:

Mass = number of moles × molar mass

Mass = 1.44 mol × 143.32 g/mol

Mass = 206.38 g

Is cobalt 60 more dangerous than bananas ( potassium 40) and why ?

maxonik [38]

Answer:

To the best of my knowledge, it is because of the amount of gamma rays is given off.

Explanation:

While both are isotopes, Potassium 40 gives off fewer gamma rays compared to Cobalt 60. Potassium 40 isn't really harmful to humans, but Cobalt 60 (I believe) is used in chemotherapy.

55 L of a gas at 25oC has its temperature increased to 35oC. What is its new volume?

ladessa [460]

Answer:

Approximately 56.8 liters.

Assumption: this gas is an ideal gas, and this change in temperature is an isobaric process.

Explanation:

Assume that the gas here acts like an ideal gas. Assume that this process is isobaric (in other words, pressure on the gas stays the same.) By Charles's Law, the volume of an ideal gas is proportional to its absolute temperature when its pressure is constant. In other words

$\displaystyle V_2 = V_1\cdot \frac{T_2}{T_1}$ ,
