How many moles of H2SO4 are needed to react with 4 moles of NaOH?
4 moles H2SO4
1 moles H2SO4
2 moles H2SO4
3 moles H2SO4
2moles of H₂SO₄ are needed to react with 4 moles of NaOH.
The number of moles present in a compound is the total number of atoms, ions or molecules present in that compound.
Number of moles of any substance
= mass of that substance/molar mass of the substance
1 mole of any substance contains 6.022 × 10²³ number of atoms, ions or molecules. 6.022 × 10²³ is also known as avogadro's number.
The mole ratio of NaOH:H₂SO₄ is 2: 1
Which means that 1mole of H₂SO₄ require 2 moles of NaOH.
Therefore 4 mole of NaOH will require: 4÷2=2 moles of H₂SO₄

At night, an equilibrium reaction between two different nitrogen compounds generates N2O5N2O5 in the atmosphere, as represented below.
Reaction 1: NO3(g)+NO2(g)⇄N2O5(g) K=2.6×10−11NO3(g)+NO2(g)⇄N2O5(g) K=2.6×10−11
During the day, solar radiation is absorbed by NO3(g), resulting in its decomposition. Which of the following best explains whether the equilibrium concentration of N2O5(g) in the atmosphere in the daytime is different from that in the nighttime, and why?
a) [N2O5] will be higher during the day, because the decomposition of NO3(g) results in an increase in the rate of production of N2O5(g).
b) [N2O5] will be higher during the day, because NO2(g) will be in excess, leading to an increase in the rate of production of N2O5(g)
c) [N2O5] will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N2O5(g) to reform NO3(g)
d) [N2O5] will be about the same at nighttime and daytime, because the amount of NO2(g) will not be changed and the equilibrium will not be affected.
The breakdown of NO3 in the day leads to more consumption of N2O5 in the day hence its concentration is greater at night than in the day.
What is equilibrium constant?The equilibrium constant is a number that shows how much reactants are converted to products in a reaction. It is often shown as capital letter K in English.
Given the situation described in the question, we know that the concentration of N205 will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N2O5(g) to reform NO3(g).

5. How many grams of cuso4 are needed to prepare 100. Ml of a 0. 10 m solution?.
Answer:
Remember that there are 5 moles of water for every 1 mole of hydrate
159.61g mol−1(159.61+5×18.015)g mol−1×100=63.92% CuSO4
This tells you that for every 100 g of copper(II) sulfate pentahydrate, you get 63.92 g of anhydrous copper(II) sulfate. Use this as a conversion factor to get
1.596g CuSO4⋅100 g CuSO4⋅5H2O63.92g CuSO4=2.497 g CuSO4⋅5H2O

What is the connection between kinetic energy, temperature, and freedom of movement?
Explanation:
They have a directly proportional relationship.
i.e.
when one of them varies in magnitude, the others will also vary directly.
Quantities expressed as products of each other are always inversely proportional & those expressed as quotients are directly proportional with each other.
KE = 1/2mv^2
Thus, we know that m & v in KE are inversely related.
Inverse proportionality - when m increases, v decreases. & vice versa.
Direct proportionality - when v increases KE also increases
If Temperature increases then the probability of atoms to randomly collide with each other increases rapidly.
the rapidity of these atoms result from the increase in speed(v). since v & KE have a direct r/n ship, KE also increases. as a result the atoms get a relatively high freedom of movement compared to that of those in solids.
Which of these describes why a stent is used?
O A. To open an artery near the heart
O B. To repair a weak heart valve
O C. To increase the biocompatibility of a heart transplant
O D. To enhance the durability of a pacemaker
SUBMIT
Answer:the correct answer is A.To open an artery near the heart
Explanation:I just took the test :)
A stent is used to open an artery near the heart and the correct option is option A.
A stent is commonly used in medical procedures to open up narrowed or blocked arteries near the heart. It is a small, mesh-like tube typically made of metal or synthetic materials. The stent is inserted into the affected artery and expands, effectively widening the artery and improving blood flow. This procedure is known as coronary angioplasty or stenting.
The narrowing or blockage of arteries can occur due to atherosclerosis, a condition in which plaque builds up on the artery walls. This can lead to reduced blood flow and potentially result in chest pain (angina) or even a heart attack. By placing a stent, the artery is opened up, allowing for improved blood flow to the heart muscle.
Thus, the ideal selection is option A.

Dr. Steiner and her team have been using GPS to track two plates that are moving toward each other. Which diagram shows what is happening at the place where the plates are moving toward each other?
Answer:
One plate is going underneath the other plate and sinking into soft rock below.
Explanation:
Tectonic plates will move each other to form rocks and mineral layers. The correct diagram which showing the result of two tectonic plates to each is diagram C. One plate is going underneath the other plate and sinking into the soft rock below.
What is plate movement?Earth's lithosphere composed of tectonic plates of different sizes and shapes. These plates move away or each other results in the formation of soft rocks and mineral layers.
The magma inside the mantle of earth crust become hot fluid by convection and it flows out. This flow of magma creates slight movement in tectonic plates finally they move in different directions.
The rocks in earth crust will undergoes weathering and results in sand formation. The boundaries of the tectonic plate will be different in different regions and characteristics of that region depends on the type of boundary such as presence of islands volcanoes etc.
When two tectonic plates moves each other one plate is going underneath the other plate and sinking into the soft rock below. Hence, option C correct.

A balloon filled with air has a volume of 4.24 liters at 23.00°C. If the balloon is cooled at constant pressure to 5.00°C, what is its new volume?
Answer:
The new volume if the balloon is cooled at constant pressure is 3.98 L
Explanation:
The new volume is calculated using the Charles law formula
that is V1/ T1 = V2/T2 where,
V1 = 4.24 l
T1= 23c into kelvin = 23 +273 =296 K
T2 = 5.00 c into kelvin = 5.00 + 273 = 278 K
V2 = ?
by making V2 subject the subject of the formula by multiplying both side by T2
V2 = V1 xT2/ T1
V2 = (4.24 L x 278 K) / 296 k = 3.98 L

The chemical equation shown represents photosynthesis. Carbon dioxide plus A plus light with a right-pointing arrow towards B plus oxygen. The arrow has an x above it. B represents a substance in a plant involved in photosynthesis. What is its role?
Answer: Option B; It traps light energy and converts it into chemical energy.
Explanation: This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.This pigment is present only in plants, so option A is incorrect.This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.
