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
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
