Misha Larkins [42]
F = G(m1 m2)/(r)^2

Let m1 be the mass of Mars
Let m2 be the mass of Deimos.
Therefore, 6m2 is the mass of Phobos.

We know that G, m1, and m2 are just constants.

Phobos:

Fp = G(m1 * 6m2)/(9000000m)^2 = 7 × 10^(-14) * G m1 m2

Deimos

Fd = G(m1 * m2)/(23000000m)^2 = 2 × 10^(-15) * G m1 m2

Mars exerts a stronger gravitational force on Phobos since Fp > Fd

What are hybrid orbitals?
Ann [662]
Hybrid Orbitals: are used to describe the orbitals in covalently bonded atoms sp,sp2,sp3

You can find the hybridization by adding the number of bonded atoms and the number of lone pairs.

For example in BF3. The central atom (B) is bonded to three atoms. So the hybridization is sp2

In NH3, the central atom (N) is bonded to three atoms and has one lone pair. The hybridization is sp3

ira [324]

Question:

What is the total combined mass of carbon dioxide and water that is produced?

Answer:

<u><em>109 kg</em></u>

Explanation:

When 23 kg of gasoline burns by consuming 86 kg oxygen, they produce carbon dioxide and water. To find the total combined mass of carbon dioxide and water, we will use mass conversation law.

According to mass conversation law, the mass of the product is equal to the mass of reagent.

Mass of reagent = Mass of product

In this reaction,

Gasoline + O2 → CO2 + H2O

23 kg + 86 kg → ?

23 kg + 86 kg =  109 kg

Combined mass of carbon dioxide and water will be 109 kg.
