Answer:

50g

Explanation:

moalr mass of CaCO3= 40g/mol+ 12g/mol+(16g/mol*3)

                                   =52g/mol+48g/mol

                                   =100g/mol

1 mol= 100g

0.5mol=x

by cross multiplication,

0.5*100gmol=x mol

x=50g

Answer: There is 0.8 liters (L) of water required to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

Explanation:

Given: [tex]M_{1}[/tex] = 0.5 M        

[tex]V_{1}[/tex] = 4800 mL

Convert mL into L as follows.

[tex]1 mL = 0.001 L\\4800 mL = 4800 mL \times \frac{0.001 L}{1 mL}\\= 4.8 L[/tex]

[tex]M_{2}[/tex] = 3 M

Formula used to calculate the volume of water required as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula.

[tex]M_{1}V_{1} = M_{2}V_{2}\\0.5 M \times 4.8 L = 3 M \times V_{2}\\V_{2} = \frac{0.5 M \times 4.8 L}{3 M}\\= 0.8 L[/tex]

Thus, we can conclude that 0.8 liters (L) of water need to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

Answer:

The rate at which the air temperature changes with height in the atmosphere surrounding a cloud or a rising parcel of air. The overall average rate is a decrease of about 6.5°C/km, but the rate varies greatly in different regions of the world, in different airstreams, and at different seasons of the year.

Answer:

The pressure of O₂ is 0.8 atm.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case:

PT=Pnitrogen + Pcarbon dioxide + Pother gases

Being:

and replacing:

PT= 593.4 mmHg + 3 mmHg + 7.1 mmHg

you get:

PT= 603.5 mmHg

Being 760 mmHg= 1 atm, you get:

PT= 603.5 mmHg= 0.8 atm

The pressure of O₂ is 0.8 atm.

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.

A)extrusion

Explanation:

The feature that causes a gap in the geologic record is called extrusion.

Sometimes magma can force itself through a crack or fault in the rock at the Earth's surface. It pours out over the Earth's surface in a volcanic eruption. This process is called extrusion. The rocks that form from extruded magma are called extrusive igneous rocks.

Direct Extrusion, Indirect Extrusion, Hydrostatic Extrusion and Lateral or Vertical Extrusion are some types of extrusion.

Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. Beneath the surface, magma may push into bodies of rock. There, the magma cools and hardens into a mass of igneous rock called an intrusion.

Therefore, The feature that causes a gap in the geologic record is called extrusion.

Answer:

203.63 K

Explanation:

Using Charles law equation,

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information in this question,

V1 = 675.6 mL

V2 = 410.9 mL

T1 = 61.8°C = 61.8 + 273 = 334.8K

T2 = ?

Using V1/T1 = V2/T2

675.6/334.8 = 410.9/T2

Cross multiply

675.6 × T2 = 334.8 × 410.9

675.6T2 = 137569.32

T2 = 137569.32 ÷ 675.6

T2 = 203.63 K

Answer:

The energy required is 8660.96 J.

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). This heat is given by the expression:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

Replacing:

Q= 4.18 [tex]\frac{J}{g*C}[/tex] *74 g* 28 C

Solving:

Q= 8660.96 J

The energy required is 8660.96 J.

Answer:

H₃P phosphidic acid

Explanation:

The Trihydrogen monophosphide, as stated in the exercise, can act as an acid. This is pretty similar to the case of hydrogen chloride, which is a gas but it can also be an acid, in this case, chloridic acid.

In the case of trihydrogen phosphide, we can write it molecular formula which is:

H₃P

Now, this is a binary compound because its composed of only two elements, in this case, hydrogen and phosphide. To name binary acid, we need to name the non metal with the sufije idic, and then, the word acid.

Following this simple rule, the trihydrogen phosphide would be, as acid:

H₃P: phosphidic acid
