Explanation:

Sublimation is the conversion of a substance from the solid to the gaseous state without its becoming liquid. ... Freeze-drying of food to preserve it involves sublimation of water from the food in a frozen state under high vacuum. See also vaporization; phase diagram.

3) A child has a toy balloon with a volume of 1.8 liters. The temperature of the balloon when it was filled was 22° C and the pr
mestny [16]

This is a combined gas law problem, according to which

\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}

where P is the pressure of the gas, V is the volume of the gas, and T is the temperature of the gas, and the subscripts 1 and 2 correspond to the initial and final conditions of the gas. In this problem, we are given the initial pressure, volume, and temperature of the gas in the balloon:

P₁ = 1.0 atm

V₁ = 1.8 L

T₁ = 295.15 K (K = °C + 273.15).

Moreover, we are given the final pressure and temperature of the gas in the balloon.

P₂ = 0.86 atm

T₂ = 281.15 K.

What we want to find is the final volume, V₂, which we can obtain by rearranging the combined gas equation to solve for V₂:

V_2=\frac{P_1V_1T_2}{T_1P_2} = \frac{(1.0 \text{ atm})(1.8 \text{ L})(281.15 \text{ K})}{(295.15 \text{ K})(0.86 \text{ atm})} \\ V_2 = 1.99 \text{ L}

This answer has three significant figures. However, the question as written would warrant an answer that comprises one significant figure (as 8 °C has only one sig fig). In that case, the answer would be 2 L. If the answer is to be given to two significant figures, the volume would then be 2.0 L.

How many grams of zinc oxide can be produced from 7.3 moles of oxygen? *
eimsori [14]

Answer:

Mass = 1188.13 g

Explanation:

Given data:

Mass of ZnO produced = ?

Moles of oxygen = 7.3 mol

Solution:

Chemical equation:

2Zn + O₂       →      2ZnO

Now we will compare the moles oxygen and and ZnO.

               O₂          ;        ZnO

                1            :           2

              7.3          :           2/1×7.3 = 14.6 mol

Mass of ZnO:

Mass = number of moles × molar mass

Mass = 14.6 mol × 81.38 g/mol

Mass = 1188.13 g

One electron in an atom has the quantum number set (3, 1, 0, ½), and another electron in the same atom has the quantum number se
guapka [62]
There are four quantum numbers that describe the placement of electrons in an atom's electron cloud: principal quantum number (n), angular quantum number (l), magnetic quantum number (ml) and electron spin number (ms). When presented, they are written as (n, l, ml, ms).

From the given set, they have same n and l quantum numbers. The n represents the shell, the l as subshell, ml is the orientation in space and ms is the direction of the spin. Therefore, these two electrons of the atom share a subshell but differ in the shape of the orbital only.
