Answer:
Molecules in the gas move faster due to the fact they have more energy
Explanation:
If you put more heat the higher the volume will be. Less heat means less volume.

Answer:
d- 7.58 L
Explanation:
According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.
Mathematically, V1/T1 = V2/ T2
V1= initial volume= 6.6 L
T1= Initial temperature= 115 °C= (115 °C +273)=388K
V2= final volume
T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K
Substitute the values,
V2=( V1 × T2)/ T1
= (6.6×446)/388
= 2943.6/388
= 7.6L
Answer:
Explanation:
Take out your periodic table.
The choices that have one 1 member of the periodic table on it are elements.
He is the symbol for Helium
O2 oxygen
C3 but this is really odd. It is Carbon but Carbon usually does not combine in 3s.
The rest are all compounds (they are made up of the elements on the periodic table). For example
H2SO4
is made up of 2 Hydrogens
1 sulfur
4 oxygens.
All the others do exactly the same thing.
Answer:
Conduction only happens when the object is a solid, because conduction happens in objects that are closely, with molecules that are closely packed together, and have a definite shape. Since, in liquids and gases, the shape is not definite nor do they have closely packed molecules., conduction does not take place in them
Answer:
Explanation:
Hello.
In this case, for the given balanced reaction:
For 10.0 g of iron (III) oxide (molar mass = 160 g/mol), based on the 1:2 mole ratio with Al (atomic mass = 27 g/mol), the required mass is then:
Moreover, as 5.3 g of aluminum oxide are actually yielded, from the 10.0 g of iron (III) oxide, we can compute the theoretical mass of aluminum oxide (molar mass = 102 g/mol) via their 1:1 mole ratio:
Thus, the percent yield (actual/theoretical*100%) turns out:
Best regards.
