Answer : The limiting reactant is 
Explanation : Given,
Mass of 
= 30.0 g
Mass of = 75.0 g
Molar mass of = 44 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 1 mole of
So, 2.34 moles of react with 
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Therefore, the limiting reactant is
The correct answer is:
a positron is emitted when proton converts to a neutron.
The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.
Answer:
A neutron is a subatomic particle with no charge and is found in the nucleus of an atom.
An atom is the smallest particle of an element that retains its identity in a chemical reaction.
Explanation:
hope this helps!! p.s. i really need brainliest :)
Based on concentration of solute particles and hence the osmotic pressure the solutions can be classified into three categories , with respect to other solutions
a) isotonic: when concentration of one of the solution is same as of the other solution then they are referred as isotonic to each other.
b) hypertonic: When concentration of the solution is greater than the concentration of other solution then it is said to be hypertonic.
c) hypotonic: when concentration of the solution is lesser than the concentration of other solution then it is said to be hypotonic.
So a solution with high concentration of solute will have higher osomotic pressure and will called to have high pressure or tone hence called as hypertonic.
Thus compartment A will have high concentration and will called as hypertonic while the compartment B will have low concentration and will called as hypotonic
Methane (CH4) is an organic compound an a hydrocarbon. The statement above is a fact and therefore the answer to the question is letter "A" or "A.True". I hope this helps you on your assignment.
