No reaction

Explanation:

NaClO₄ → Sodium perchlorate

Ni(NO₃)₂ →  Nickel (II) nitrate

All the salts from nitrate are soluble salts

All the salts from perchlorate are soluble salts except for the KClO₄

Iron(II) sulfate, an iron supplement , FeSO4 Express your answer to four significant figures and include the appropriate units.
strojnjashka [21]

Answer:

Molar mass = 151.9 g/mol

Explanation:

The molar mass of a compound is obtained by adding u the individual atomic masses in the compound. The unit is g/mol.

In FeSO4, we have one Fe, one S and 4 O.

The atomic masses are given as follows;

Fe = 55.845 u

S =  32.065 u

O = 15.999 u

Molar mass = ( 1 * Fe) + (1 * S) + (4 * O)

Molar mass = (1 * 55.854 ) + ( 1 * 32.065) + (4 * 15.999)

Molar mass = 151.915  g/mol

In four significant figures;

Molar mass = 151.9 g/mol

kiruha [24]

Answer:

y = 5cos(\frac{2\pi }{6} x)

Explanation:

You can put that equation into a program like desmos on your browser and take a screenshot or use windows snippet tool.

Equation of a Wave: y = Acos(((2*pi)/B)x)

or

y = Acos(\frac{2\pi }{B} x)

A = Amplitude

B= Wavelength
