Explanation: The Ice Would Sink Toward the Bottom

Density of Ice at 0 Celsius is 0.92 grams per milliliter. Therefore the Ice has a greater density than ethanol, and the ice cube should sink toward the bottom

you are given an unknown gaseous binary compound. when 10.0g of the compound isburned in excess oxygen, 16.3g of water is produc
Flauer [41]
Since the compound has 1.38 time that of oxygen gas at the same conditions of temperature and pressure, we have the relationship:
MW/MWoxygen = 1.38
MW = 44.16

Since there is water formed during the reaction, the formula of the compound must be:
XaHb
where a and b are the coefficients of each element.

If the compound reactions with oxygen forming water and an oxide of the element X, the combustion reaction must be:
XaHb + ((2a + (b/2))/2) O2 = a (XO2) + (b/2)(H2O)
Using dimensional analysis:
10 (1/44.16) (b/2 / 1) (18) = 16.3
Solving for b:
b = 8

The compound now is XaH8. Most probably, the compound is C3H8 since it has a molecular formula of 44 and it reacts with O2 to form water and CO2.

the pressure of a has is 1.0 atm and it occupies a volume of 2.50 L. What will he the new volume of this has if the pressure is
NikAS [45]

Answer:

<h2>1.25 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{1 \times 2.5}{2}  =  \frac{2.5}{2}  \\

We have the final answer as

<h3>1.25 L</h3>

Hope this helps you
