Answer:
The answer to your question is d. Li₂SO₄
Explanation:
Data
H₂SO₄ reacts with LiOH
Process
This is a neutralization reaction that occurs between an acid and a base and the products will always be water and a binary or ternary salt.
In this reaction, the acid is H₂SO₄ and the base is LiOH, then the products will be water and Lithium sulfate.
Balanced chemical reaction
H₂SO₄ + LiOH ⇒ Li₂SO₄ + H₂O
The new item formed is called a product.
P2 = 54.6 kPa
Explanation:
Given:
V1 = 10.0 L. V2 = 50.0 L
P1 = 273 kPa. P2 = ?
We can use Boyle's law to solve this problem.
P1V1 = P2V2
Solving for P2,
P2 = (V1/V2)P1
= (10.0 L/50.0 L)(273 kPa)
= 54.6 kPa
<h2>Answer:</h2>
The compound is known as the neurotransmitter or messenger chemicals.
<h3>Explanation:</h3>
- Neurotransmitters are the chemicals a type of messenger which is used to transmit information from one cell to the next cell.
- Some hormones are also known as messenger chemicals.
- The nerve cells are not linked to each other while they are separated from each other by a space known as synapses.
- The electric potential signal is converted into chemical signal by the release of neurotransmitters.
- These neurotransmitter signal next cell to produce equal amount of electric signal in nerve cell.
Answer:
850g/min
Explanation:
The reaction expression is given as:
P₄ + 5O₂ → P₄O₁₀
Given that:
Number of moles of product = 1.5moles
Time = 30s = 0.5min
Unknown:
The rate of the reaction = ?
Solution:
Convert the moles given to mass of the product.
So;
Mass of product = number of moles x molar mass
Molar mass of P₄O₁₀ = 4(31) + 10(16) = 284g/mol
Mass of product = 1.5moles x 284g/mol = 426g
So;
Reaction rate = 
= 
= 850g/min
