Answer:
1.2 x 10²⁴ atoms
Explanation:
Given:
Number of moles of Ag = 2moles
Unknown is the number of atoms it contains:
Solution:
A mole of any substance is known to be made up of 6.02 x 10²³ atoms
Now;
2 moles of an atom will contain:
2 x 6.02 x 10²³ = 1.2 x 10²⁴ atoms
Answer:
51.1 g NH3
The required chemical reaction is given by:
N2 + 3H2 --> 2NH3
4.5 mol H2 × (2 mol NH3/3 mol H2) = 3 mol NH3
molar mass of NH3 is 17.031 g/mol
3 mol NH3 × (17.031 g NH3/1 mol NH3) = 51.1 g NH3
Answer:
Sigma bonds: 10
Pi bonds: 4
Explanation:
The compound described must be CH2=CH-CO-CH≡CH. If we look at the compound closely, we will notice that there are 10 sigma bonds and 4 pi bonds.
There are three pi bonds between carbon atoms and one pi bond between a carbon and an oxygen atom (C=O). All these can easily be seen in the structure of the formula chosen in this answer.
Answer:
6.Given,
Final Velocity =60m/s
Initial Velocity= 0
Time=10 sec
A=?
A=Final Velocity- Initial Velocity/time
=60-0/10
=60/10
=6m/s ans.
Explanation:
Acceleration = Final Velocity - Initial Velocity/Time
By using this Formula we can calculate Acceleration.
Latitude and Temperature
At the equator, the Sun's rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun's rays are less direct. The farther an area is from the equator, the lower its temperature.
