Answer: Ethyl Ethanoate can be used as a developing solvent. It’s safer.
Explanation:Di ethyl ether should be carefully used because it’s highly flammable and intoxicating when inhaled and can cause explosions because of its high reactivity to air and light.

Answer:
D. Catalyst
Explanation:
Because a Catalyst is a substance that causes or accelerates a chemical reaction without itself being affected.
<h3>
Answer:</h3>
2.83 g/cm³
<h3>
Explanation:</h3>
- Density of a substance is the ratio of mass of the substance to its volume.
Therefore;
- Density is given by dividing mass of a substance by its volume.
- It is measure in g/cubic centimeters or kg per cubic meters.
In this case;
Density of Al = 2830 Kg/m³
We are required to convert is to g/cm³
We use the relationship;
1 g/cm³ = 1000 kg/m³
Therefore;
= 2830 kg/m³ ÷ 1000 kg/m³
= 2.83 g/cm³
Hence, 2830 kg/m³ of Aluminium is equivalent to 2.83 g/cm³
