The balanced equation is:
Then proceed with the following equations.
The answer is
.
Answer:
See below
Explanation:
The common formula of the same alkene series is CnH2n, where n is the quantity of atoms of carbon. Owing to the hydrocarbons of alkenes with at least one double carbon relation, the alkene-like sequence starts with ethen C2H4.

Sn(s) + 2 HF(aq) ----> SnF2(s) + H2(g)
M HF = 20 g/mol
M SnF2 = 157 g/mol
40 g (HF) -----> 157 g (SnF2)
30 g (HF) -----> x g (SnF2)
x = 30 g × 157 g / 40 g = 117,75g
Answer: 117,75 g

Answer:
temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above.The Earth's magnetic field is generated by the outer core.
Explanation:
Answer:
Electrons are in orbitals, each orbital can take two electrons and each electron would have an opposite spin. - Orbitals can have no electrons, one electron or be filled with two electrons. - Orbitals are arranged in energy levels
