Balance the following chemical equations

IrinaVladis [17]

Answer:

Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below

Always use the upper case for the first character in the element name and the lower case for the second character.

To enter an electron into a chemical equation use {-} or e

To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}. Example: Fe{3+} + I{-} =...

Substitute immutable groups in chemical compounds to avoid ambiguity. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2...

The average daily demand for component B is 750 units. The average time for waiting during the production process and materials

Greeley [361]

Answer:

4 containers

Explanation:

Given

Average daily demand, d= 750 units

Average time for waiting during production and materials handling, w = 0.15 days

Processing time per container, t = 0.1 days

Container capacity, c = 50 units

Policy variable, α = 5% = 0.05

Number of containers required for component B is calculated as follows;

Total Production/Container Capacity.

Total Production = d(w + t)(1 + α)

Total Production = 750 * (0.15 + 0.1) * (1 + 0.05)

Total Production = 196.875

Number of containers = 196.875/50

Number of containers = 3.9375

Number of containers = 4 --- approximated

What is the electric flux φ through each of the six faces of the cube? Use ϵ0 for the permittivity of free space?

exis [7]

If total charge Q is enclosed in the surface of cube

then we will have say that total flux linked with all surfaces of the cube will be given by

$\phi = \frac{Q}{\epsilon_0}$

since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube

So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces

so flux linked with each face is given by formula

$\phi = \frac{Q}{6\epsilon_0}$

so each face will have above flux due to central position of charge Q
