Answer:
One million of silver atoms weigh 1.79 xx 10^(-16)g. Calculate the atomic mass of silver. Atomic mass of silver =107.8g=107.8u
Answer:
Elements can be separated into smaller atoms
Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant = 
T = Temperature of gas = ?
Now put all the given values in above equation, we get:
Therefore, the temperature of gas is, 295 K
A compound differs from an element in that it can be decomposed by a chemical reaction.
A compound, by definition, is made up of two or more elements that have been combined together through a chemical bond.
Thus, the chemical bond or bonds in a compound can be decomposed by a chemical reaction giving rise to the individual elements that make up the compound.
This is unlike an element that can not be decomposed by any chemical reaction.
