Answer:
2 
bonds and 2 
bonds
Explanation:
If we consider the the bonding in the 
molecule:
Thus carbon forms double bonds with oxygen:
O = C = O
Now,
We know that double bond comprises of a 
and a 
Since, in the , there are 2 double bonds thus there are 2 bonds and 2 bonds in the molecules.
Answer:
533.92 m/s
Explanation:
The root-mean-square speed of a gas is given by v = √(3RT/M)
R = molar gas constant = 8.3145 J/mol-K
T = Temperature = 320 K
M = Molar mass of Nitrogen in kg/mol = 2 × 14 × 10⁻³ kg/mol = 28 × 10⁻³ kg/mol
v = √(3RT/M) = √(3 × 8.3145 J/mol-K × 320 K/28 × 10⁻³ kg/mol) = √7981920/28 = √285.068.57 = 533.92 m/s
For me: WASH OUR HANDS REGULARLY
Answer:
I don't know what you mean about which changes occurred in this process but if its why the dough starts rising then its caused by the carbon dioxide in baking soda and yeast which is a fungus
