Answer:
Atomic mass of Gallium is 69.7230 amu
Explanation:
100 atoms of gallium contains 60.11 number of 
atoms and 39.89 number of 
atoms.
Therefore atomic mass of gallium is given by-
= 
= 69.7230 amu
Answer:
23.76g
Explanation:
To solve for the mass of carbon dioxide (CO2), let us first obtain the number of mole of CO2.
From the question, the following were obtained:
V = 8.13L
P = 204kPa = 204000Pa
Recall: 101325Pa = 1atm
204000Pa = 204000/101325 = 2atm
T = 95°C = 95 + 273 = 368K
R = 0.082atm.L/K/mol
n =?
PV = nRT
n = PV /RT
n = 2 x 8.13/ 0.082 x 368
n = 0.54mole
Now let us convert 0.54mole of CO2 to gram. This is illustrated below:
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Number of mole of CO2 = 0.54mole
Mass of CO2 =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of CO2 = 0.54 x 44
Mass of CO2 = 23.76g
Given :
A chemical equation :
To Find :
What is the type of reaction :
A. Single replacement
B. Decomposition
C. Double replacement
Solution :
We know when a single compound turns into two or more compounds or element, this type of reaction is said to be decomposition reaction.
In the given equation 
decomposes into 
and 
.
Therefore, the given reaction is decomposition reaction.
Answer:
If one is standing in flowing water and thicker liquid, it will be easier to resist the force of the thicker liquid in comparison to water .
It is so because the thicker liquid has an internal resistance that acts when the liquid is in motion, and it is easy to oppose the motion of thicker liquid while water do not have internal resistance and it become harder to resist teh force.
