Answer : The correct option is, (c) pyramidal
Explanation :
As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.
There are total 4 electron pairs. So, the hybridization will be 
and the electronic geometry of the molecule will be tetrahedral.
But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.
Hence, correct option is, (c) pyramidal
Answer:
=745 Kelvin
Explanation:
- According to the pressure law the relationship between the pressure and absolute temperature of a gas at a constant volume is directly proportional.
- An increase in temperature causes a corresponding increase in pressure at a constant volume.
That is;
Mathematically;
When there are two varying conditions;
In this case;
P1 = 0.8 atm
T1 = 25+273 = 298 K
P2 =2.00 atm
T2= ?
Therefore;
Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
Answer:
Explanation:
As one moves down the vertical groupings of elements on the periodic table, it is evident that new shells are being added from top to down.
An atomic orbital is the region of space surrounding the nucleus where there is a high probability of finding an electron.
Down a group, the atomic radius increases as more shells are added to an atom.
The units of ppm means parts per million. Also, It is equivalent to milligrams per liter. It is one way of expressing concentration of a substance. It u<span>sually used to describe the concentration of something in water or soil. We calculate the mass of CaCO3 as follows:
Mass = 75 mg/L (.050 L) = <span>3.75 mg CaCO3</span></span>
