Answer:

Sperm Cell

Explanation:

Answer: D

Explanation:

The car will move to the left because Sam is implying a grater force (3 N < 6 N) but it is traveling at a constant speed because there is still a force being acted upon it. <3

The result of applying forces to a toy car is required.

Option D is correct.

Force applied by Bobby is 3 N to the right

Force applied by Sam is 6 N to the left

Right is taken as positive and left is taken as negative.

m = Mass of toy

a = Acceleration

Net force applied to the toy

[tex]F=3-6\\\Rightarrow F=-3\ \text{N}\\\Rightarrow ma=-3\\\Rightarrow a=\dfrac{-3}{m}[/tex]

So, the toy will move left with a constant acceleration.

Constant acceleration means its speed will be increasing.

So, option D is correct.

Answer:

Molarity of a solution where one mole of NaOH is added to 2000mL of water is 0.0005

Explanation:

Molarity is the equal to number of moles of solute divided by total volume of solvent

Given -

Number of moles of solute i.e  NaOH = 1

Total volume of solvent i.e water = 2000 mL

Molarity [tex]\frac{1}{2000} = 0.0005[/tex]

Answer:

13.25 M

Explanation:

Molarity is moles over liters so simply plug your values in as such:

5.30 mol ÷ 0.400 L = 13.25 M

Answer:

The correct answer is - 100 grams.

Explanation:

The solubility graph is a very useful tool because it tells you the amount of solute that can be dissolved per  100 mL  of water in order to have a saturated solution of potassium nitrate at a given temperature.

In order to find the solubility of the salt at  30 ∘ C , start from the  30 ∘ C

mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the  y  axis and read off the value that you land on which is 200. However, it is for 100 ml so half the value you read:

200/2 = 100 gram .

So, solubility  ≈  100 g / 50 mL water

So, a saturated solution of solute will hold about  100 g  of dissolved solute, that is of dissociated solute, per 50 mL  of water at  30 ∘ C .

Answer:

Tomar 82 mL de solución concentrada y agregar agua hasta un volumen final de 1.0 L.

Explanation:

Tenemos una solución concentrada de hipoclorito de sodio, cuya concentración es 6.1%, por lo tanto:

Cc = 6.1 %

Y debemos hacer una dilucion para obtener una solucion diluida con:

Cd = 0.5%

Vd = 1.0 L

Por lo tanto, podemos usar la siguiente fórmula para calcular el volumen a tomar de solucion concentrada (Vc):

Cc x Vc = Cd x Vd

⇒ Vc = (Cd x Vd)/Cc = (0.5% x 1.0 L)/6.1% = 0.082 L

0.082 L x 1000 mL/1 L = 82 mL

Por lo tanto, para preparar la solución debemos tomar 82 mL de solucion concentrada de hipoclorito de sodio 6.1% y agregar agua hasta un volumen final de 1.0 L.

Answer:

Molality = 9.498 mol  k g − 1

Explanation:

A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

molality = number of moles of solute/ mass of solvent in kg

number of moles of KI = mass of KI / molar mass of KI  

number of moles of KI = 9.49.8 g / 1.00 g  m o l − 1

number of moles of KI = 9.498 moles  

molality = 9.498 moles / 1kg  

molality = 9.498 mol  k g − 1

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

Answer:

Q = 63.9 kJ

Explanation:

Given that,

Mass of ice, m = 300 g

We need to find the heat needed to heat the given amount of ice at -5.00°C into steam at 100.°C

The specific heat of ice, c = 2.03 J/g °C

The formula for heat needed is given by :

[tex]Q=mc\Delta T\\\\Q=300\times 2.03\times (100-(-5))\\\\Q=63945\ J\\\\Q=63.9\ kJ[/tex]

So, 63.9 kJ of heat is needed.

Speed of jays increases first, again increases, decreases and then increases.

Explanation:

The speed of jays increases while moving from rest to point A and no acceleration due to constant speed. From point A to point B, the speed is continues to increase and no acceleration. From point B to point C, the speed of jays decreases and acceleration is produced in the journey due to change of speed and from point C to point D, the speed of jays again increases and acceleration is produced due to increasing the speed.

Answer:

The speed of jay's walk increases first, again increases, then it decreases and then increases due to his acceleration walk during parts A-D.

Answer:

because Sulphur is written as S₂

Explanation:

Answer:

The final pressure is approximately 0.78 atm

Explanation:

The original temperature of the gas, T₁ = 263.0 K

The final temperature of the gas, T₂ = 298.0 K

The original volume of the gas, V₁ = 24.0 liters

The final volume of the gas, V₂ = 35.0 liters

The original pressure of the gas, P₁ = 1.00 atm

Let P₂ represent the final pressure, we get;

[tex]\dfrac{P_1 \cdot V_1}{T_1} = \dfrac{P_2 \cdot V_2}{T_2}[/tex]

[tex]P_2 = \dfrac{P_1 \cdot V_1 \cdot T_2}{T_1 \cdot V_2}[/tex]

[tex]P_2 = \dfrac{1 \times 24.0 \times 298}{263.0 \times 35.0} = 0.776969038566[/tex]

∴ The final pressure P₂ ≈ 0.78 atm.
