Hmm trick question here's my answer: the content: protons charge the electrons into its usage , the size: 1.6fm if I'm wrong sorry if I'm right: HA IN YOUR FACE HA!!!
Balanced equation
2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂
<h3>Further explanation</h3>
Given
Word equation
Required
Chemical equation
Solution
Chemical equations can be expressed in
- word equation
- skeleton equation
- balanced equation
Aluminum chlorate = Al(ClO₃)₃
Barium sulfate = BaSO₄
Aluminum sulfate = Al₂(SO₄)₃
Barium chlorate = Ba(ClO₃)₂
Al(ClO₃)₃ + BaSO₄⇒ Al₂(SO₄)₃ + Ba(ClO₃)₂
2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂
They push away from each other or repel due to the same charge they have.
Answer:
a) CaF₂.
b) 7.81g of CaF₂ are present.
Explanation:
a) The calcium ion has as charge Ca²⁺ and fluoride ion is F⁻, that means formula unit is:
CaF₂
b) 1 molecule of CaF₂ contains 2 anions, F⁻. Thus, the moles of CaF₂ is:
1.2x10²³ anions * (1 moleculeCaF₂ / 2 anions) = 6x10²² molecules of CaF₂
6.022x10²³ molecules = 1mol:
6x10²² molecules of CaF₂ * (1mol / 6.022x10²³molecules) = 0.10 moles CaF₂.
1 mole of CaF₂ has a mass of 78.07g:
0.10 moles CaF₂ * (78.07g / mol) =
7.81g of CaF₂ are present
Answer:
1. The organism becomes ill or may die.
2. Pathogens.
Explanation:
(1) When an organism fails to maintain homeostasis, the organism typically becomes ill, and they will die if homeostasis cannot be re-achieved.
(2) A pathogen is a virus that can cause diseases.
