The nature of zinc powder and Cobalt (II )oxide is heated the following reaction occurs ;
Scilla [17]

1) The metal which reduces the other compound is the one higher in the reactivity. So in this case it is \mathrm{Zn}.

2) The substance which brings about reduction while itself getting oxidised (that is losing electrons) is called a reducing agent. Here, $\mathrm{Zn}$ is the reducing agent and reduces Cobalt Oxide to Cobalt while itself getting oxidised to Zinc oxide.

Jimmy's Chemical reaction/ Recipe for making Grilled chese sandwiches is given below: 1 slice of cheese + 2 slices of bread = 1
Juli2301 [7.4K]

Answer:

See explanation

Explanation:

We have been told in the question that the equation of the reaction is; 1 slice of cheese + 2 slices of bread = 1 Grilled cheese sandwich ( mole ratio is, 1:2:1) .

Then the reagents are 10 slices of cheese 30 slices of bread. It then follows that 10 slices of cheese should be combined with 20 slices of bread according to the mole ratio.

However, we have 30 slices of bread and 10 slices of cheese so cheese is the limiting reactant while bread is the reactant in excess.

Yes, the number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.

How is the wavelength of an electromagnetic wave related to the energy of the wave?
Sauron [17]

The equation that relates both energy and wavelength is:

e=\frac{h*c}{lambda}

where e is the energy and lambda is the wavelength.

Therefore, as we can see from this equation, the energy of an electromagnetic wave is inversely related to the wavelength of the electromagnetic wave.

How to solve what volume of 12.0 m hcl is required to make 75.0 ml of 3.50 m hcl?
pochemuha
75mL=0.075L

Molarity=moles/Liters
Moles=0.075(3.50)
=0.2625

Since the number of moles never changes,
we know there are 0.2625moles (or 0.26) in the 12M HCl.
0.2625/12=0.021875L

(0.022L)
