The limiting reagent when 5 g of NaOH and 4.4 g CO₂ allowed to react will be NaOH
<h3>What is Limiting reagent ?</h3>
The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
Given chemical equation in balanced form ;
2NaOH(s) + CO₂(g) → Na₂CO₃(s) + H₂O(l).
According to the Chemical equation ;
- The limiting reagent when 5 g of NaOH and 4.4 g CO₂ allowed to react will be NaOH
If 44 g CO₂ requires 80 g of NaOH, therefore, 4.4 g CO₂ will require atleast 8 g of NaOH.
But the available quantity is 5 g NaOH. thus, NaOH is the Limiting reagent.
- 6.625 g of Na₂CO₃ are expected to be produced 5.0 g of NaOH and 4.4 g of CO₂ are allowed to react
As 80 g NaOH produces 106 g of Na₂CO₃.
Therefore 5 g NaoH will produce ;
106 / 80 x 5 = 6.625 g

Answer:
0.052L
Explanation:
Molarity of a substance, which refers to the molar concentration, is calculated as follows:
Molarity (M) = number of moles (mol) ÷ volume (L)
Mole = mass ÷ molar mass
Molar Mass of AgNO3 since Ag = 108, N = 14, O = 16
108 + 14 + 16(3)
= 108 + 14 + 48
= 170g/mol
Mole = 21.89 g ÷ 170g/mol
Mole = 0.129moles
Using Molarity (M) = number of moles (mol) ÷ volume (L)
Volume = number of moles ÷ molarity
V = 0.129 ÷ 2.50
V = 0.0516
To the correct significant figure i.e. 4s.f, the numerical value of volume = 0.052L
Pressure and volume are inversely proportional <span />
Answer: Absolute zero is denoted as 0 K on the Kelvin scale, −273.15 °C on the Celsius scale, and −459.67 °F on the Fahrenheit scale.
Explanation: the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F.
The difference is actually a result of the the depth. Ponds, according to limnology (the study of water bodies) are shallow enough where plants could conceivably grow across the entire surface. ... As a result, there are some very small bodies of water, less than an acre that are deep enough to be called lakes.
