Answer:

The correct option is: CO₂

Explanation:

Greenhouse effect refers to the natural phenomenon by which the Sun's radiation increases the temperature of the Earth's surface.

The incoming Sun's radiation is radiated by the greenhouse gases present in the Earth's atmosphere. A fraction of the radiated energy is then absorbed by the Earth's surface, thus resulting in increase in the temperature.

<u>Thus the green house effect depends upon the amount of green house gases present in the atmosphere.</u>

The green house gases are the r<u>adiatively active gases.</u> The main four green house gases are: water vapor (H₂O(g)), carbon dioxide (CO₂), methane (CH₄) and ozone (O₃).

<u>Human activities such as burning of fossil gases and deforestation increases the concentration of </u><u>CO₂ </u><u>significantly.</u><u> Thereby contributing to the greenhouse effect.</u>

What mass in grams of SO2 is needed to react with 37.50 mol of Oz?
-BARSIC- [3]

Answer:

4804.5 g of SO₂ are needed to the reaction

Explanation:

The reaction to produce sulfuric acid is:

2SO₂ + O₂ + 2H₂O →  2H₂SO₄

Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.

If 1 mol of O₂ react to 2 moles of SO₂

Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂

We convert the moles to mass, to know the answer:

75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂

What ions will form when baking soda is dissolved in water?
ad-work [718]

Answer:When you add baking powder to water or milk, the alkali and the acidreact with one another and produce carbon dioxide – the bubbles. Sodium bicarbonate is a weak base which is commonly known as baking soda and used in cooking. It weakly ionizes in water: NaHCO3 + H2O → H2CO3 + (OH-) + (Na+). u need to stop deleteing my answers ughh

A negatively charged balloon has 2.6 µc of charge. how many excess electrons are on this balloon? the elemental charge is 1.6 ×
Salsk061 [2.6K]
The given 2.6 µC of charge is due to a buildup of electrons, each of which has a charge of 1.6 x 10^-19 C. The 2.6 <span>µC is equivalent to 2.6 x 10^-6 C, so we can divide this by the individual charge of an electron:
</span>2.6 x 10^-6 C / 1.6 x 10^-19 (C/electron) = 1.625 x 10^13 electrons

What is/are the product(s) of a neutralization reaction of a carboxylic acid? View Available Hint(s) What is/are the product(s)
lutik1710 [3]

Answer:

A carboxylate salt and water

Explanation:

A carboxylic acid is an organic compound that has general formula RCOOH, where R is a carbon chain. Because it's an acid, the neutralization will happen when it reacts with a base, such as NaOH.

When this reaction occurs, the base will dissociate in Na⁺ and OH⁻, and the acid will ionize in RCOO⁻ and H⁺, so the products will be RCOO⁻Na⁺ (a carboxylate salt) and H₂O (water).
