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
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 temperatureAccording 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.

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.
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.

calculate the number of atoms in a sample containing 3.5 g of silicon atoms
Answer:
there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
Explanation:
So, 1 mole of silicon will have a mass of 28.0855 g and the number of atoms will be 6.022 x 1023. Therefore, there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
Answer:
1 mole of silicon will have a mass of 28.0855 g and the number of atoms will be 6.022*1023 . Therefore , there are 7.505*1022 atom in 3.5 g of silicon .

Explanation:
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
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/s²Replacing 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
