if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4 according to this UNBALANCED equation below, how many grams of AgSO4 could be formed? AgNO3+H2SO4->Ag2SO4+HNO3
Answer:
62.36 g
Explanation:
AgNO3 + H2SO4 - > Ag2SO4 + HNO3
The balanced equation is given as;
2AgNO3 + H2SO4 → Ag2SO4 + 2HNO3
From the equation;
2 mol of AgNO3 reacts with 1 mol of H2SO4
if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4
The limiting reactant us AgNO3 as it determines the amount of products to be formed.
2 mol of AgNO3 produces 1 mol of Ag2SO4
0.2 mol of AgNO3 would produce x mol of Ag2SO4
Solving for x;
2 = 2
0.2 = x
x =0.2 * 2/ 2 = 0.2 mol
Converting moles to mass;
Mass = Number of Moles * Molar mass
Mass = 0.2 mol * 311.8 g/mol
Mass = 62.36 g
What is the molarity of 6.2 moles of NaCl in 2.5 L of water?
Full work plz
Molarity= no. of moles of solute/ volume of solution(in L)
Molarity = 6.2 moles/ 2.5 L = 62/25 mol/L
= 2.48 mol/L
Identify at least four limiting factors in the local ecosystem and their impact on native populations.
4 limiting factors could be water, space, pollution, and access to mates, could all be factors in limiting the native population. Water, could be affected by pollution, and this would remove water, which means that no living things would be able to survive, or at the best be hindered in its growth. Space could be removed by deforestation, or simple water rising, and this could kill off the population, thus removing mates for the population. (hope this helped, if it did, please consider marking brainiest)
The availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.
What are the limiting factors?The limiting factors such as availability of food, water, shelter and diseases can change animal and plant populations because these factors has a direct impact on the organisms and the organisms is depend on these factors for their survival.
So we can conclude that availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.

What is the density of a book with a mass of 60g and a volume of 20 cm3? *
Answer:
[tex]3 g/cm^{3}[/tex]
Explanation:
Density is a measure of a substance's mass over its volume.
d = m/v
Therefore d = 60g/20cm3 = 3 g/cm3
Compare the Atomic Radius of Lithium (Li) and
Potassium (K) and EXPLAIN.
Answer:
Lithium has a smaller atomic radius than potassium
Explanation:
Lithium has fewer electrons therefore fewer orbitals (1s2, 2s1) vs Potassium with more electron and therefore orbitals (1s2, 2s2, 2p6, 3s2, 3p6, 4s1)

Scientist are studying photosynthesisIn in a forest ecosystem that has plants animals and decomposers
Answer:
Ecosystem is food web of primary and secondary producers and consumers.
Explanation:
In an ecosystem, there exist primary producers, primary consumers, secondary consumers, and tertiary consumers such as detritivorous such as viruses and bacteria that act on the living bodies and recycle the nutrients back to plants through the soil. The primary producers such as all green plants and others make their own food being autotrophs they use sunlight and carry out photosynthesis process. On the depend on the herbivorous they eat grass etc. The secondary consumers are carnivores as heterotrophs that feed on herbivores.differentiate between hypothesis and Theory

The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

If you have 12 atoms of hydrogen before a chemical reaction, how many atoms of hydrogen will be present
Answer:
12 atoms of hydrogen will be present in the product
Explanation:
12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
The law of conservation states that the mass of the element remains the same during the course of the reaction.
The law of reaction conformed by the following:-
Mass of reactant Mass of productAccording to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms
Hence, the amount remains the same in the reaction that is 12 atoms

Which is the correct number of moles of nitrogen monoxide that is produced from 13.2 moles of oxygen gas in the presence of excess ammonia (NH3)?
Answer:
10.56 moles of NO will be produced
Explanation:
The balanced reaction of ammonia, NH₃ with oxygen, O₂ is:
4NH₃ + 5O₂ → 4NO + 6H₂O
Where 5 moles of oxygen react with an excess of ammonia to produce 4 moles of nitrogen monoxude.
If 13.2 moles of O₂ react:
13.2 mol O₂ * (4 mol NO / 5 mol O₂) =

40 g of NaCl is added to 1500 g of water. What is the molality of the resulting
solution?
Molality = moles of solute/mass (in kg) of solvent
The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.
The solvent here is water, of which you have 1500 g or 1.500 kg H2O.
The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.
If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.
