Find the acceleration of the 2 kg block in the following diagram. ( Hint find the net force!)
The acceleration of the block will be -2 m/s² in the backward direction.
What is force?
Force is defined as the product of mass of the body and the acceleration with which it is moving. Mathematically -
F = ma
It is a vector quantity. In the three dimensional coordinate system, the force vector can be resolved as -
[F] = F[x] a[x] + F[y] a[y] + F[z] a[z]
Given is a diagram in which two forces are acting on a block.
We can write -
Force 1 on block [F1] = 4 a[x]
Force 2 on block [F2] = 8 (- a[x]) = - 8 a[x]
Resultant of forces [F] = [F1] + [F2] = 4 a[x] + ( - 8 a[x]) = - 4 a[x]
Now, we know that -
F = MA
A = F/M
In vector form, acceleration will be -
[A] = - 1/m × (4 a[x])
[A] = -1/2 × (4 a[x])
[A] = - 2 a[x]
Therefore, the acceleration of the block will be -2 m/s² in the backward direction.

buffer is prepared by adding 275 mL of .676M of HCl to 500 mL of .525M sodium acetate. What is the pH?
The pH of the buffer prepared by adding 275 mL of .676M of HCl to 500 mL of .525M sodium acetate is 6.45.
How to calculate pH?The pH of a buffer solution can be calculated by initially calculating the millimoles of both the conjugate base and acid.
Millimoles of hydrochloric acid = 275mL × 0.676M = 185.9millimolesMillimoles of sodium acetate = 500mL × 0.525M = 262.5millimolesFrom, Henderson Hasselbalch equation,

A solution consists of 35.00 g of CuSO4 dissolved in 250.0 mL of water. The molar mass of Cu is 63.55 g/mol the molar mass of S is 32.07 g/mol, and the molar mass of O is 16.00 g/mol. What is the molarity of the solution?
The molarity of a solution that contains 35.00 g of CuSO4 dissolved in 250.0 mL of water is 0.88M.
How to calculate molarity?The molarity of a solution can be calculated using the following formula:
Molarity = no of moles/volume
According to this question, a solution consists of 35.00 g of CuSO4 dissolved in 250.0 mL of water.
no.of moles of CuSO4 = 35g ÷ 159.6g/mol
no. of moles of CuSO4 = 0.22 moles
Therefore; molarity of CuSO4 solution is calculated as follows:
M = 0.22 ÷ 0.25
M = 0.88M

If 3.500 moles of water react completely according to the following equation, how much heat must be absorbed in kilojoules? 6CO2+6H2O→C6H12O6+6O2ΔH=2,803 kJ
The amount of heat absorbed in kilojoules when 3.5 moles of water react is 1635.08 KJ
Balanced equation6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ ΔH = 2803 KJ
From the balanced equation for above,
6 moles of water reacted to absorb 2803 KJ of heat
How to determine the heat absorbedFrom the balanced equation for above,
6 moles of water reacted to absorb 2803 KJ of heat
Therefore,
3.5 moles of water will react to absorb = (3.5 × 2803) / 6 = 1635.08 KJ of heat
Thus, 1635.08 KJ of heat were absorbed by the reaction.

If 4.65 LL of CO2CO2 gas at 22 ∘C∘C at 793 mmHg mmHg is used, what is the final volume, in liters, of the gas at 35 ∘C∘C and a pressure of 743 mmHg mmHg , if the amount of CO2CO2 does not change?
Answer:
About 7.9 L.
Explanation:
We can utilize the ideal gas law. Recall that:
[tex]\displaystyle PV = nRT[/tex]
Because the amount of carbon dioxide does not change, we can rearrange to formula to:
[tex]\displaystyle \frac{PV}{T}= nR[/tex]
Because the right-hand side stays constant, we have that:
[tex]\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR[/tex]
Hence substitute initial values and known final values:
[tex]\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}[/tex]
Therefore, the final volume is about 7.9 L.

Lead(II) oxideExplanation:
Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula PbO. PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure. Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components. It is an amphoteric oxide.[3]IUPAC nameLead(II) oxideOther namesLead monoxideLithargeMassicotPlumbous oxideGalena PreparationPbO may be prepared by heating lead metal in air at approximately 600 °C (1,100 °F). At this temperature it is also the end product of oxidation of other oxides of lead in air:[4]Thermal decomposition of lead(II) nitrate or lead(II) carbonate also results in the formation of PbO:2 Pb(NO3)2 → 2 PbO + 4 NO2 + O2PbCO3 → PbO + CO2PbO is produced on a large scale as an intermediate product in refining raw lead ores into metallic lead. The usual lead ore is galena (lead(II) sulfide). At a temperature of around 1,000 °C (1,800 °F) the sulfide is converted to the oxide:[5]2 PbS + 3 O2 → 2 PbO + 2 SO2Metallic lead is obtained by reducing PbO with carbon monoxide at around 1,200 °C (2,200 °F):[6]PbO + CO → Pb + CO2pls brainlest meh
How is fission different than alpha or beta decay?
Fission is when the parent atom splits into two daughter products. Whereas atom with a mass number is lower by 4 and an atomic number is lower by 2.
Is nuclear fission alpha or beta?Fission outcomes emit beta radiation, while actinides mainly emit alpha radiation. Many of each also radiate gamma radiation.
The beta decays form an isobaric, fission-product decay chain for each mass number.
Thus, Fission is when the parent atom splits into two daughter products.
