I’m pretty sure the answer is
↳ To transport materials throughout the body!
Multicellular organisms need a circulatory system to transport substances to and from their cells!
There you go! I hope this helped, if there’s anything just let me know! ☻
Ionization is a process in which an electron present in the outermost orbital of an atom gets knocked out by absorbing an appropriate amount of energy. Release of electron from a neutral atom results in the formation of a cation- a positively charged ion.
Rubidium (Rb) is an alkali metal with a valence electron configuration of 5s¹. Ionization results in the loss of this '5s' electron forming a Rb+ ion. The reaction can be expressed as:
Rb (5s¹) → Rb⁺ (5s⁰) + e⁻

Question:
What is the total combined mass of carbon dioxide and water that is produced?
Answer:
<u><em>109 kg</em></u>
Explanation:
When 23 kg of gasoline burns by consuming 86 kg oxygen, they produce carbon dioxide and water. To find the total combined mass of carbon dioxide and water, we will use mass conversation law.
According to mass conversation law, the mass of the product is equal to the mass of reagent.
Mass of reagent = Mass of product
In this reaction,
Gasoline + O2 → CO2 + H2O
23 kg + 86 kg → ?
23 kg + 86 kg = 109 kg
Combined mass of carbon dioxide and water will be 109 kg.
