1 answer:

4 0

Answer:Small-scale technique means a small quantity of chemicals that contribute to the safety of the experiments. Instead of using big beaker of chemical, micro scale technique utilize small quantities of chemical and scaled-down science equipment.

Arsenic produces a blue flame when heated. Calcium produces an orange-red flame. Which of these best explains why this differenc

MrMuchimi

Flame colors are produced from the movement of the electrons in the metal ions present in the compounds. When you heat it, the electrons gain energy and can jump into any of the empty orbitals at higher levels Each of these jumps involves a specific amount of energy being released as light energy, and each corresponds to a particular color. As a result of all these jumps, a spectrum of colored lines will be produced. The color you see will be a combination of all these individual colors.

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?

arsen [322]

Answer:

92.65256 cm^3

Explanation:

To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.

An aluminum ion has a charge of +3, and an oxide has a charge of -2. What would be the product of a reaction between these two e

kozerog [31]

The product of a reaction between these two elements is $Al_{2} O_{3}$ .

Explanation:

The oxidation state of an ion in a compound is equal to its charge.

The aluminum having a charge of +3 because oxidation state is +3

The oxide is having charge of -2

The product of these reactants will produce a chemical compound.

The compound formed is $Al_{2} O_{3}$ i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.

The +3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+.

A waste collection tank can hold 18754 kg of methanol, which has a density of 0.788 g/cm3.

quester [9]

Given:
Mass of methanol, m = 18754 kg
Density of methanol, ρ = 0.788 g/cm³

By definition, the volume of methanol in the collection tank is
Volume = mass/density
$= \frac{(18754 \, kg)*(10^{3} \, \frac{g}{kg}) }{(0.788 \, \frac{g}{cm^{3})} } \\ \\ =2.38 \times 10^{7} \, \frac{g}{cm^{3}}$

Answer: 2.38 x 10⁷ g/cm³
