Glass 1 Freshwater  

The egg went directly to the base of the glass. Consequently it has sunk and did not drift  

237.0  

237 (1 glass)  

1.000

Glass 2  

Water with 2 teaspoons of salt  

A similar outcome for glass 2 as container 1 when egg was set into the container it sank to the base.  

248.4  

237  

1.048

Glass 3  

Water with 3 teaspoons of salt  

In reference to glass 1 and 2 the egg sank to the base for a third time.  

254.1  

237  

1.072  

Glass 4  

Water with 4 teaspoons of salt  

The egg remained gliding to where a little bit of the egg was standing out on the top, and when pushed down the egg returned up.  

259.8  

237  

1.096

Hope this helps!

A reaction between liquid reactants takes place at −10.0°C in a sealed, evacuated vessel with a measured volume of 45.0L. Measur
maks197457 [2]

Answer: 0.0624 atm

Explanation:-

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = ?

V= Volume of the gas = 45.0 L

T= Temperature of the gas = -10.0°C = 263 K    0^00C=273K

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas

Moles of gas=\frac{\text{ given mass}}{\text{ molar mass}}= \frac{19.0g}{146g/mole}=0.130moles

P=\frac{nRT}{V}=\frac{0.130\times 0.0821\times 263}{45.0}=0.0624atm

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm

What is the typical percentage (by mass of elements other than hydrogen and helium in stars that are forming right now in the vi
Ipatiy [6.2K]
Considering mass percentages, stars in the vicinity of the sun contain only 2% other elements by mass. Other than the main components, hydrogen and helium, stars have some heavier elements such as carbon, nitrogen, oxygen and iron. These elements are found near or in the star's core and are ejected into space when the star dies.

adell [148]
I found this is the order of activity in Internet

Mn>Zn>Cr>Fe>Cd>Co>Ni>Pb

You can see that Fe is between Cr and Cd

Cr is more active than Fe and Fe is more active than Cd.

The Fe will displace Cd but not Cr.

Answer:Fe
