Answer:

Because it is in such high concentrations that it cannot be compensated with its natural elimination process.

Explanation:

Substances like carbon dioxide are produced naturally by living beings in the breathing process. This carbon dioxide is taken by plants for their photosynthesis process, but currently, the carbon dioxide is also produced by the burning of organic materials in industries. The quantities that are produced are exceeding the capacity of the plants to transform it, which causes gas to accumulate in the atmosphere damaging the ozone layer

Because despite being natural they still harm the ozone layer and cause breathing problems, even suffocation.

The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v).

vovangra [49]

Answer:

Density is an intensive property

Explanation:

The intensive properties don´t depend on mass or size, if you have a liter of water, this litter have a density equal 1000 kg/m^3. If zo have 250 liters of water, the density is 1000 kg/m^3 too.

The density does not change with the addition or substraction of matter.

I hope I have been clear.

Consider the atom with the chemical symbol Ru.

Vinil7 [7]

Answer: 97

Explanation:

The element Ru is Ruthenium which has 44 protons.

In this case, our atom is an isotope with 53 neutrons.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = 44 protons + 53 neutrons

mass number = 97

What is the scaling factor if the molar mass of

Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

$sf=150/30=5$

Therefore, we can also infer that the molecular formula would be:

$C_5H_1_0O_5$

Best regards!
