Answer:
a) Sodium Chloride is the limiting reactant.
b)285g of Ba3(PO4)2
Explanation:
a) 1000g Nacl x (1mol of Nacl/58.5g) x (2 Mol Na3PO4/6 mol of NaCl)= 5.70
- 2000g Ba3 (PO4)2 X 1 mol of Ba3 (PO4)2/601.9 x 2 mol of Na3PO4/1 mol of Ba3 (PO4)2= 6.65
Hence; NaCl is the limiting Reactant.
b) 1000g Nacl x (1mol of Nacl/58.5g) x 1 mol of Ba3 (PO4)2/ 6 mol of NaCl x601.9g/1 mol= 1715g Ba3(PO4)2 USED.
2000g- 1715g=285g of Ba3(PO4)2 Left.
Sodium chloride is a limiting reagent.
284 grams of barium phosphate (excess reactant) are left.
Explanation:
Given:
[tex]6NaCl+Ba_3(PO_4)_2\rightarrow 2Na_3PO_4+3BaCl_2[/tex]
1000 grams of sodium chloride and 2000 grams of barium phosphate.
To find:
The limiting reactant and mass of excess reactant left.
Solution:
Mass of sodium chloride = 1000 g
Moles of sodium chloride =[tex]\frac{1000 g}{58.44 g/mol}=17.11mol[/tex]
Mass of barium phosphate = 2000 g
Moles of barium phosphate =[tex]\frac{2000 g}{601.93 g/mol}=3.323 mol[/tex]
[tex]6NaCl+Ba_3(PO_4)_2\rightarrow 2Na_3PO_4+3BaCl_2[/tex]
According to reaction, 6 moles of sodium chloride reacts with 1 mole of barium phosphate, then 17.11 moles of sodium chloride will react with:
[tex]=\frac{1}{6}\times 17.11mol=2.852 \text{ mol of }Ba_3(PO_4)_2[/tex]
2.852 moles of barium phosphate reacted with 17.11 moles of sodium chloride.
But according to the question, we have 3.323 moles of barium phosphate which is more than 2.852 moles.
This indicates that barium phosphate is an excessive reagent and sodium chloride is a limiting reagent.
Moles of barium phosphate left unreacted:
[tex]=3.323 mol - 2.852 mol = 0.471 mol[/tex]
Mass of 0.471 moles of barium phosphate:
[tex]=0.471 mol\times 601.93 g/mol=283.51\approx 284 g[/tex]
Sodium chloride is a limiting reagent.
284 grams of barium phosphate (excess reactant) are left.

Barium chloride solution was used to test for sulfate ions in the presence of dilute hydrochloric acid. What color precipitate would
form if sulfate ions were present?
Answer:
white
Explanation:
A white precipitate of barium sulfate forms if sulfate ions are present. The hydrochloric acid is added first to remove any carbonate ions that might be present - they would also produce a white precipitate, giving a false positive result. Barium nitrate solution can be used instead of barium chloride solution

The symbol equation for combustion of a hydrocarbon is shown below. What number will go before the oxygen reactant when
this equation is balanced?
Answer:
Yes it is indeed
Explanation:
Thanks if you found this helpful
The balanced chemical equation is [tex]\rm C_3H_8 + 5O_2- \rightarrow 3CO_2 + 4H_2O[/tex].
What is chemical equation?Chemical equation is defined as a formulation of mathematics that captures the chemical reaction. We can learn about the reactants and products involved in a chemical reaction by developing a chemical equation. It includes the symbols for the atoms of each element found in the compound, together with a count of how many of each element there are overall in the form of subscripts.
Chemical equations must be balanced in order to satisfy the law of conservation of mass, which states that "the total mass of all products of reaction in a chemical reaction is equal to the total mass of all reactants." A chemical equation is said to be balanced when the number of various elemental atoms on the reactants and products sides are equal. Chemical equations must be balanced by a process of trial and error.
Thus, the balanced chemical equation is [tex]\rm C_3H_8 + 5O_2- \rightarrow 3CO_2 + 4H_2O[/tex].

Answer:
Malaria
Explanation:
Mosquitos mainly carry Malaria since the dawn of men.
Answer:
malaria
Explanation:
"Malaria" is a mosquito-borne illness that is caused by a parasitic protist called "Plasmodium protozoa." These parasites are carried by mosquitoes. Once a mosquito bites a human, it creates an opening for the parasites to enter. The parasites then become harmful once they enter the human body. They infect the human's Red Blood Cells (RBCs), which causes several symptoms such as fever, fatigue, headache, cough, nausea, etc.

A fixed mass of oxygen gas occupies 300cm cube at 0 degree centigrade. what volume would the gas occupy at 15 degree centigrade
Answer:
Volume occupied by oxygen gas at 15 degree centigrade is equal to [tex]316.5[/tex] centimeter cube
Explanation:
Assuming Pressure is constant.
[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]
where T1 and T2 are temperature in Kelvin
Substituting the give values we get-
[tex]\frac{300}{273} = \frac{V_2}{288}[/tex]
[tex]V_2 = \frac{288*300}{273} \\V_2 = 316.5[/tex]
Volume occupied by oxygen gas at 15 degree centigrade is equal to [tex]316.5[/tex] centimeter cube
2. A sample of oxygen gas is placed in a rigid 1.5L glass container at STP. If the gas is
heated to 100 degrees (Celcius) what is the new pressure in mmHg?
The new pressure : P₂ = 1038.39 mmHg
Further explanationGiven
1.5 L container at STP
Heated to 100 °C
Required
The new pressure
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).
So P₁ = 1 atm = 760 mmHg
T₁ = 273 K
T₂ = 100 °C+273 = 373 K
Gay Lussac's Law
When the volume is not changed, the gas pressure is proportional to its absolute temperature
[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]
Input the value :
P₂=(P₁.T₂)/T₁
P₂=(760 x 373)/273
P₂ = 1038.39 mmHg

How much heat is released when 24.8 g of ch4 is burned in excess oxygen gas?
The given question is incomplete. The complete question is:
How much heat is produced when 24.8 g of [tex]CH_4[/tex] is burned in excess oxygen gas
Given: [tex]CH _4 +2O_2\rightarrow CO_2+2H_2O[/tex] ΔH= −802 kJ.
Answer: 1243.1 kJ
Explanation:
Heat of combustion is the amount of heat released on complete combustion of 1 mole of substance.
Given :
Amount of heat released on combustion of 1 mole of methane = 802 kJ kJ/mol
According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
1 mole of [tex]CH_4[/tex] weighs = 16 g
Thus we can say:
16 g of [tex]CH_4[/tex] on combustion releases heat = 802 kJ
Thus 24.8 g of [tex]CH_4[/tex] on combustion releases =[tex]\frac{802}{16}\times 24.8=1243.1kJ[/tex]
Thus heat released when 24.8 g of methane is burned in excess oxygen gas is 1243.1 kJ
