Answer:

-2

Explanation:

The model of the oxygen atom will probably have an electrical charge of -2.

Now let us explain how to find the charge on any atom.

The charge on an atom is the number of electrons gained or lost by specie. Electrons are usually lost in any atom so that they can attain stability.

These electrons are removed from the valence shell because they are the outermost shell electrons. They are most weakly held electrons in an atom.

An atom of oxygen has:

     8 electrons with a configuration of 1s² 2s² 2p⁴

   Charge = number of protons - number of electrons

        neutral oxygen has 8 electrons and protons, charge is 0

When baking soda (NaHCO3) is heated, it decomposes, producing carbon dioxide, water, and sodium carbonate. The carbon dioxide is
11Alexandr11 [23.1K]

Answer:

mass of carbon-dioxide = 0.262 g

Explanation:

Firstly, write the chemical equation of the reaction and balance the equation accordingly.

2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)

Calculate the molecular mass of  baking soda

molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g

2 moles of baking soda = 2 × 84 = 168 g

molar mass of CO2 = 12 + 32 = 44 g

if  168 g of baking soda produces 44 g of carbon-dioxide

1 g of baking soda will produce ? grams of carbon-dioxide

cross multiply

mass of carbon-dioxide = 44/168

mass of carbon-dioxide = 0.2619047619

mass of carbon-dioxide = 0.262 g

murzikaleks [220]

Answer: Option C) The unicellular organism creates a new organism.

Explanation:

Cell division involves the multiplication of cells whereby one cell divides into two daughter cells or offsprings, two divides into four and so on.

In unicellular organisms, cell division could be by the following ways:

- Binary fission in Ameoba

- Budding in Hydra

- fragmentation in Sponges.

Thus, each of these unicellular organisms divides to give rise to new organisms that are similar to their parents
