what happens when carbon dioxide gas is cooled to -78 degree Celsius​

Answers

Answer 1

Answer:

It will be solid

Explanation:

-78 C° is the freezing point of carbon dioxide, so at the temperature of -78 Celsius, the particles of carbon dioxide will come closer together and have about a fixed position to vibrate. The carbon dioxide will turn into solid. The solid form of carbon dioxide is also called dry ice.

Jane made this picture to represent a chemical reaction:

Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.

Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)

It represents a synthesis reaction because one combined reactant forms multiple products.

It represents a synthesis reaction because the same atoms are present in the reactants and products.

It represents a decomposition reaction because one reactant breaks apart and forms two products.

It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.

Answers

The reaction represents a decomposition reaction because XY is broken into its constituents.

A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.

Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

1. Cu + 2AgNO3 ==> 2Ag + Cu(NO3)2 ... balanced equation. This is both a single replacement reaction and an oxidation reduction reaction.
Moles of Cu present = 19.0 g Cu x 1 mole Cu/63.55 g = 0.2990 moles Cu
Moles AgNO3 = 125 g AgNO3 x 1 mole AgNO3/169.9 g = 0.7357 moles AgNO3
Which reactant is limiting? It will be Cu because the mole ratio is 2 AgNO3 to 1 Cu and there is more than enough AgNO3. Thus, amount of Ag formed will depend on moles of Cu (0.2990)
Moles of Ag formed = 0.2990 moles Cu x 2 moles Ag/mole Cu = 0.598 moles Ag
Mass (grams) of Ag formed = 0.598 moles Ag x 107.9 g/mole = 64.52 g = 64.5 g of Ag (3 sig. figs.)

A sample of a certain gas has a volume of 452 mL at 711 mmHg and 26 degrees C. What would be the volume of this same sample of gas if it were measured at STP

Answers

The volume of this same sample of gas if it were measured at STP is 386.09mL

HOW TO CALCULATE VOLUME:

The new volume of a gas sample can be calculated using the following expression:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressureP2 = final pressureV1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperature

According to this question, a sample of a certain gas has a volume of 452 mL at 711 mmHg and 26°C (299K).

(711 × 452)/299 = 760 × V2/273

1074.82 = 2.78V2

V2 = 1074.82 ÷ 2.78

V2 = 386.09mL

Therefore, the volume of this same sample of gas if it were measured at STP is 386.09mL.

The bowl of fruit has a mass of 2.2 kg.
What net force must act on the bowl of fruit to make it accelerate to the right
at a rate of 4.4 m/s2? (Hint: Use F = ma.)
A. F = 9.68 N right
B. F = 9.68 N left
C. F = 6.60 N left
D. F= 6.60 N right

Answers

Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right

In first place, acceleration in a body occurs when a force acts on a body.

Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.

So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object

Mathematically, Newton's second law is expressed as:

F= m×a

where:

F = Force [N] m = Mass [kg] a = Acceleration [m/s²]

In this case, you know:

F= ? m= 2.2 kg a= 4.4 m/s²

Replacing in Newton's second law:

F= 2.2 kg× 4.4 m/s²

Solving:

F= 9.68 N

Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right
