Explanation:
Hello!
In this case, since calcium's oxidation state when forming ionic bonds is +2 and sulfur's oxidation state when bonding those bonds is -2, for the required formula we write:
Now, since they have the same charge number, we infer the ionic compound formed when they bond is calcium sulfide:
Best regards!
If the earth's orbit is far from the sun, then, its rate will be slower than when it is closer to the Sun. When gravitational field lines get closer together,
the magnetic force is strong. We
know that the heavier the body is, the stronger its gravitational pull.<span>

Answer:
P(total) = 164 mmHg
Explanation:
Given data:
Partial pressure of helium = 77 mmHg
Partial pressure of nitrogen = 87 mmHg
Total pressure of flask = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(He) + P(N₂)
P(total) = 77 mmHg + 87 mmHg
P(total) = 164 mmHg
