Answer: from the lies this is synthesis reaction
Explanation:
It's also oxidation-reduction reaction. Li is oxidised and
H is reduced
According to Bohr, the electrons in an atom were only allowed to exist at certain energy levels. ... Just as children cannot hover between two steps on a staircase, Bohr suggested that electrons cannot hover between two energy levels in the atom. Bohr developed his energy level model further using principles from physic
Answer:
14.32g
Explanation:
Initial temperature = 83.8°C
Final temperature = 77.1°C
Temperature change, ΔT = 83.8°C - 77.1°C = 6.7
Heat, H = 167J
Specific heat, c = 1.740J/g °C
m = ?
All these parameters are related with the equation below;
H = mcΔT
m = H / cΔT
m = 167 / (1.740 * 6.7)
m = 167 / 11.658 = 14.32g
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
