LiCl, because lithium (Li) has one positively charged ion (1+), and
chloride (Cl) has one negatively charged ion (1-), so they
cancel each other out.
<u>Answer:</u>
<em>They are a lot of religions and faiths across the globe.
</em>
<u>Explanation:</u>
There are a lot of monotheistic and polytheistic religions across the world that took origin at different points in the past.
Some of them are:
- Christianity- It is a monotheistic religion based on the teachings of Jesus Christ believed to be the son of god.
- Confucianism it evolved in China and is based on the teachings scholar and philosopher Confucius. It is a largely secular and humanistic.
- Buddhism it is based on the life and teachings of Gautama Buddha. Buddhism advocates a way of life with meditation and instructs its followers to be compassionate, kind and wise.
- Hinduism –It evolved during the period of Indus valley civilisation and is a polytheistic religion. Hinduism beliefs mention rebirths or ‘punarjanma’.
- Islam- Islam is a monotheistic religion.It considers Muhammad as the messenger of only god Allah.
Answer:
Time of flight A is greatest
Explanation:
Let u₁ , u₂, u₃ be their initial velocity and θ₁ , θ₂ and θ₃ be their angle of projection. They all achieve a common highest height of H.
So
H = u₁² sin²θ₁ /2g
H = u₂² sin²θ₂ /2g
H = u₃² sin²θ₃ /2g
On the basis of these equation we can write
u₁ sinθ₁ =u₂ sinθ₂=u₃ sinθ₃
For maximum range we can write
D = u₁² sin2θ₁ /g
1.5 D = u₂² sin2θ₂ / g
2 D =u₃² sin2θ₃ / g
1.5 D / D = u₂² sin2θ₂ /u₁² sin2θ₁
1.5 = u₂ cosθ₂ /u₁ cosθ₁ ( since , u₁ sinθ₁ =u₂ sinθ₂ )
u₂ cosθ₂ >u₁ cosθ₁
u₂ sinθ₂ < u₁ sinθ₁
2u₂ sinθ₂ / g < 2u₁ sinθ₁ /g
Time of flight B < Time of flight A
Similarly we can prove
Time of flight C < Time of flight B
Hence Time of flight A is greatest .
Bottom of the distillation flask
Explanation:
The solid in the mixture to be separate would be found at the bottom of the distillation flask.
Distillation is a separation technique for differentiating the components of mixtures based on the differences in their boiling points.
- Distillation is used to recover solvents from solution.
- The solutes are then left behind in the flask as the solvent boils out as vapor.
- The solution is boiled in a distillation flask to vaporize the solvent.
- The vapor is made to condense back into liquid by means of a condenser.
- The pure liquid called distillate is collected in the receiver.
- The solute which is the solid remains in the distillation flask
